The frequent occurrence of traditional machine security systems is generating conflicts between the police and users and providers have creeping costs problems due to frequent responses. The current machine security systems simply combined with an intrusion alarm system, an access control system, and an image monitoring system have increased the security, safety, and criminal arrest ratio but the profitability of providers deteriorated considerably due to burden of investment costs. Therefore, industries have badly needed a development of new type of security system. The intelligent video security system appearing in current situation is growing its interest because it is expected to be adopted the emerging artificial intelligence. However, there is a lack of theoretical definition and researches on acceptance intention. This study is aiming to consider influential factors on acceptance intention of intelligent video security system synthetically to consolidate Information System Success Model by DeLone & McLean(2003) and Value-based Adoption Model by Kim et al.(2007). This study assumed that users recognize the intelligent video security system as an information equipment for security and safety in the analysis process of acceptance intention of intelligent video security system. Based on this realization, the major factors related with D&M IS model were analyzed to apply this study. Moreover, the intelligent video security system user was considered as a user who is responsible for expenses spontaneously as occasion demands and VAM was used for analysis to consider an aspect of Benefits and an aspect of Sacrifices from new technology use simultaneously. The study hypothesis was established to verify empirically and SPSS 22.0 and AMOS 22.0 were used for analysis. The results were as follows. First, the Benefits factors such as information quality of D&M IS model, system quality, and service quality had positive effect on acceptance intention of intelligent video security system. Second, the recognized security and the perceived expense among Sacrifices factors such as a privacy concern, recognized security, and the perceived expense did not have any effect due to rejecting hypothesis and the privacy concern had a negative effect by adopting hypothesis. Third, perceived value had a positive effect on both user satisfaction and acceptance intention and the user satisfaction had also a positive effect on acceptance intention. The most influential factor to acceptance intention of intelligent video security system was the system quality because an image analysis function could be a core factor to decide quality of intelligent video security system. Therefore, correct and detailed image analysis program should be developed for adoption of intelligent video security system by consumers. This study has a scientific meaning because it suggested new approach method combined with D&M IS model and VAM for a field of influential effect to acceptance intention of intelligent video security system. According to the study on influential effect to acceptance intention of intelligent video security system, the results from the study combined two models showed that the hypothesis of privacy concern was adopted as opposed to the information system adopted by organizations. It showed that the invasion of consumer's privacy should be considered. The results of this study would offer various implications for providers who want to offer service by using the intelligent video security system and workers who study related technology. If the intelligent video security system is commercialized in earnest, overinvesting costs of machine security system and structural problems of incorrect or frequent alarms would be solved. In addition, consumer utility could be increasing more because of lower cost and more safe state-of-the art security. 전통적인 기계경비시스템은 오·경보가 자주 발행하여 경찰 및 사용자와의 갈등요인으로 작용하였고 제공 사업자는 잦은 출동으로 인해 비용이 늘어나는 문제가 있었다. 침입경보시스템, 출입통제시스템 및 영상감시시스템이 단순하게 결합된 현재의 기계경비시스템은 보안·안전 및 범인 검거 비율은 향상되었지만 제공 사업자의 투자비 부담이 가중되어 수익성은 크게 악화 되었다. 이에 따라 업계에서는 새로운 방식의 보안시스템 개발이 절실하였다. 이러한 환경에서 등장한 지능형 영상보안시스템은 최근 새롭게 대두되고 있는 인공지능이 가장 먼저 적용될 산업으로 전망되면서 관심이 증가하고 있으나 이론적 정의와 수용의도에 관한 연구는 부족한 것이 사실이다. 이에 본 연구는 이러한 부족한 연구를 메우기 위해 DeLone & McLean(2003)의 정보시스템 성공모형(Information System Success Model)과 Kim et al.(2007)의 가치기반 수용모델(Value-based Adoption Model)을 통합하여 지능형 영상보안시스템의 수용의도에 영향을 미치는 요인에 대하여 종합적으로 고찰하는데 목적이 있다. 본 연구는 지능형 영상보안시스템의 수용의도를 분석하는 과정에서 이용자들은 지능형 영상보안시스템을 보안·안전에 필요한 정보기기로 인식한다고 가정하였다. 이와 같은 인식을 바탕으로 D&M IS 모형에 관련된 주요 요인들을 분석하여 본 연구에 적용하였다. 또한 지능형 영상보안시스템의 이용자를 개인이 필요에 따라 자발적으로 비용을 부담하는 소비자로 간주하고 신기술 사용으로 얻게 되는 편익(Benefits) 측면과 희생(Sacrifices) 측면을 동시에 고려하고자 VAM을 활용하여 분석하였다. 연구 과제를 실증적으로 검증하기 위해 연구가설을 설정하고 SPSS 22.0과 AMOS 22.0을 활용하여 분석한 결과 첫째, D&M IS 모형의 정보 품질, 시스템 품질, 서비스 품질 등 편익 요인은 지능형 영상보안시스템의 수용의도에 긍정적인 영향을 미치는 것으로 나타났다. 둘째, 프라이버시 염려, 인지된 보안, 지각된 비용 등의 희생 요인 중에서 인지된 보안과 지각된 비용은 가설이 기각되어 영향이 없는 것으로 확인되었고, 프라이버시 염려는 가설이 채택되어 부정적인 영향을 미치는 것으로 나타났다. 셋째, 지각된 가치는 사용자 만족과 수용의도에 모두 긍정적인 영향을 미치는 것으로 나타났고, 사용자 만족 또한 수용의도에 긍정적인 영향을 미치는 것으로 확인되었다. 특히, 지능형 영상보안시스템의 수용의도에 가장 큰 영향을 미치는 요인은 시스템 품질로 나타났다. 이와 같은 연구결과가 도출된 이유는 영상분석 기능이 지능형 영상보안시스템의 품질을 결정하는 핵심요인으로 볼 수 있기 때문이다. 따라서 지능형 영상보안시스템이 소비자에게 성공적으로 수용되기 위해서는 다른 무엇보다 정확하고 정교한 영상분석 프로그램 개발이 선행되어야 할 것이다. 본 연구는 D&M IS 모형과 VAM을 통합하여 지능형 영상보안시스템의 수용의도에 영향을 미치는 요인에 대한 연구 분야에서 새로운 접근방법을 제시했다는 점에서 학술적 의의가 있다. 두 가지 모델을 통합하여 연구한 결과 지능형 영상보안시스템의 수용의도에 영향을 미치는 요인에 관한 연구에서는 조직에서의 정보시스템 도입과는 다르게 프라이버시 염려라는 가설이 채택되어 소비자의 사생활 침해에 대한 고려가 필요하다는 것을 알 수 있었다. 이와 같은 결과는 지능형 영상보안시스템을 활용하여 서비스를 제공 하고자 하는 사업자나 관련 기술을 연구하는 실무자에게 많은 시사점을 제공할 것이다. 그리고 지능형 영상보안시스템이 본격적으로 상용화 된다면 기계경비시스템의 과도한 투자비와 구조적인 오·경보 문제도 극복될 것으로 기대한다. 또한 소비자는 보다 안전한 첨단 보안 서비스를 보다 저렴한 가격으로 이용할 수 있어 소비자 효용이 더욱 증가할 것으로 기대한다.

This study analyzes the impact of the spirituality of workers on job satisfaction in social work practice. The purpose of this research is to explore the overall aspects of resilience based on the personal and demographic characteristics of individuals working in social welfare facilities and their work characteristics. Furthermore, it aims to examine the relationship between the resilience of social workers and job satisfaction, and to find ways to improve job satisfaction among social workers and the quality of social welfare services. To achieve this, the following research questions were established: Fist, Does the spirituality of social workers affect job satisfaction? Second, Does the spirituality of social workers affect resilience? Third, Does the resilience of social workers affect job satisfaction? Fourth, Does the spirituality of social workers influence job satisfaction through resilience as a mediator? The subjects of the study aim to examine the relationships and influences among the factors of spirituality, job satisfaction, and resilience in social workers. The participants included 2,013 social workers employed in eight social welfare facilities located in Ansan, Gyeonggi Province. The analysis method involved conducting descriptive statistics, correlation analysis, multiple regression analysis, and Sobel tests using SPSS 22.0. The analysis results are as follows: A significant relationship was confirmed between spirituality, job satisfaction, and resilience. Horizontal spirituality positively influenced job satisfaction, while vertical spirituality did not influence the positive relationship with job satisfaction, resulting in partial acceptance of the hypothesis "the spirituality of social workers will positively affect job satisfaction." Next, in the relationship between spirituality and resilience, the horizontal spirituality of social workers positively impacted self-regulation ability, positivity, and interpersonal skills, whereas vertical spirituality had no effect, leading to partial acceptance of the hypothesis "the spirituality of social workers will positively influence resilience." The third verification of the relationship between resilience and job satisfaction found that resilience positively impacted the hypothesis regarding satisfaction with colleagues, and partially accepted hypotheses regarding satisfaction with job and supervisors, but rejected the hypothesis regarding satisfaction with compensation and promotions. Thus, the hypothesis "the resilience of social workers will positively affect job satisfaction" was partially accepted. Similarly, in testing for mediating effects using Baron & Kenny's (1986) three-step method, it was confirmed through the Sobel test that resilience has a partial mediating effect on the relationship between the independent variable, spirituality, and the dependent variable, job satisfaction. Therefore, the research hypothesis "resilience will mediate the effect of the spirituality of social workers on job satisfaction" was accepted. The implications of this study are as follows: According to the results of this study, horizontal spirituality significantly affected resilience and job satisfaction. Therefore, there is a need to develop and educate existential spirituality programs for social workers so that they can fulfill their duties effectively in challenging practice settings and promote their personal growth. Additionally, it suggests that spirituality and resilience can be one of the measures for improving the treatment of social workers. As mentioned above, the positivity and self-regulation abilities associated with horizontal spirituality and resilience positively impacted the job satisfaction of social workers. Professionals providing services in practice settings experience burnout due to poor working conditions and client violence. By enhancing the level of spirituality among workers, they can engage in self-reflection and restore their capabilities. Lastly, this study may serve as a foundational resource in the field of religious social work practice. Spirituality is an area of interest in the field of religious social work. Considering that a significant portion of Koreans practice a religion, spiritually-informed social work practice can reinforce essential skills professionals need when providing services to clients, such as rapport building, gentleness, and a non-judgmental attitude, ultimately contributing to their recovery from a strengths perspective. The limitations of this study are as follows: This study cannot be generalized. First, as this research targeted a specific subset of social welfare institutions in Ansan through convenience sampling, it has limitations in representing the population. Second, while more detailed and specific analyses, such as confirmatory factor analysis or structural equation modeling, are needed, the analysis was performed at a basic level, so the reliability and validity of the measurement tools cannot be deemed accurate. Third, the study subjects predominantly included elderly care workers, women, and those in their 50s and 60s, which does not represent all social workers. Lastly, this empirical study verified the causality between spirituality, resilience, and job satisfaction but failed to present the in-depth processes and outcomes regarding how the spirituality perceived by workers connects and influences resilience and job satisfaction. 본 연구는 사회복지 종사자의 영성이 직무만족에 미치는 영향을 분석 하였다. 연구 목적은 사회복지시설에 사회복지 종사하고 있는 개인적· 인구학적 특성 및 근무특성에 따른 회복탄력성의 전반적인 양상을 알아보고, 사회복지 종사자의 회복탄력성이 직무만족의 관계와 이에 미치는 영향을 살펴봄으로써 사회복지 종사자의 직무만족을 향상시키고 사회복 지서비스의 질을 향상시킬 수 있는 방안을 모색하는데 목적이 있다. 이를 위해 다음과 같은 연구문제를 설정하였다. 첫째, 사회복지 종사자의 영성은 직무만족에 영향을 미치는가? 둘째, 사회복지 종사자의 영성은 회복탄력성에 영향을 미치는가? 셋째, 사회복지 종사자의 회복탄력성은 직무만족에 영향을 미치는가? 넷째, 사회복지 종사자 영성의 회복탄력성을 매개로 직무만족에 영향을 미치는가? 연구 대상자는 사회복지 종사자의 영성, 직무만족, 회복탄력성 각 요인 사이의 관계와 영향력을 살펴보는 것이다. 연구 대상은 경기도 안산에 소재한 사회복지시설 8곳에 근무하는 사회복지 종사자 213명이었다. 분석 방법은 SPSS 22.0을 통해 기술통계, 상관분석, 다중회귀분석, Sobel test를 실시하였다. 분석 결과는 다음과 같다. 영성과 직무만족, 회복탄력성 사이의 유의미한 관계가 있는 것이 확인되었다. 그리고 영성의 수평적 영성이 직무만족에 정(+)의 관계에 영향을 미쳤지만 수직적 영성은 직무만족의 정(+)의 관계에 영향을 미치지 않음으로써 ‘사회복지 종사자의 영성은 직무만족에 정(+)의 영향을 미칠 것이다’의 가설은 부분 채택되었다. 다음으로 영성과 회복탄력성의 관계에서 사회복지 종사자의 수평적 영성이 자기조절능력, 긍정성, 대인관계 능력에 정(+)의 영향에 미쳤으나 수직적 영성은 미치지 않는 것으로 나타났다. 따라서 ‘사회복지 종사자의 영성이 회복탄력성에 정(+)의 영향을 미칠 것이다’ 가설을 부분 채택되었다. 세 번째 회복탄력성과 직무만족 관계를 검증한 결과 회복탄력성은 직무만족의 동료에 대한 가설은 채택 되었으며, 직무, 상사에 대한 만족의 가설에 부분 채택되었고, 보수와 승진 만족에 대해서는 기각되었다. 따라서 ‘사회복지 종사자의 회복탄력성이 직무만족에 정(+)의 영향을 미칠 것이다’ 가설은 부분 채택되었다. Baron & Kenny(1986)의 3단계 매개효과 검증 분석과 동일하게 Sobel test에서도 독립변수인 영성과 종속변수인 직무만족의 관계에서 회복탄력성은 부분 매개 효과가 있는 것으로 검증되었다. 이에 연구가설 ‘사회 복지 종사자의 영성이 직무만족에 미치는 영향에서 회복탄력성은 매개효과가 있을 것이다’는 채택되었다. 본 연구의 함의는 다음과 같다. 본 연구 결과에 의하면 영성 중 수평적 영성이 회복탄력성과 직무만족에 유의미한 영향을 미쳤다. 따라서 사회복지 종사자가 힘든 실천 현장에서 자신의 본연의 업무를 충실히하고 자기 성장을 위해 사회복지 종사자들을 위한 실존적 영성 프로그램을 개발하고 교육시킬 필요가 있다. 영성과 회복탄력성을 사회복지 종사자의 처우 개선을 위한 방안 중에 하나가 될 수 있다는 것을 시사했다. 상기한 것처럼 수평적 영성과 회복 탄력성의 긍정성과 자기조절 능력은 사회복지 종사자의 직무만족에 긍정적인 영향을 미쳤다. 실천현장에서 서비스를 제공하는 종사자들은 열악한 근무 환경과 클라이언트 폭력으로 인해 소진을 경험하게 된다. 이를 방지하고 극복하기 위해서 종사자들의 영성 정도를 높여준다면 성찰하면서 스스로 회복하고 능력을 높일 수 있을 것이다. 마지막으로 종교 사회복지 실천 분야에 기초자료로 제공할 수 있을 것이다. 종교 사회복지 분야에서 영성은 관심분야이다. 한국 사람들의 상당수가 종교를 갖고 있다는 점을 감안할 때 영성적 사회복지 실천은 종사자들이 클라이언트에게 서비스를 제공할 때 필수 기술인 라포형성이나 온화함, 비심판적 태도 등을 강화할 수 있고 강점 관점에서 이들이 회복하는데 기여할 것이다. 본 연구의 제한점은 다음과 같다. 이 연구는 안산시 소재 일부 사회복지 기관을 대상으로 유의표집 방식이기 때문에 모집단을 대변하는 데에 한계가 있다. 두 번째 본 연구 분석은 확인적 요인 분석이나 구조 방정식 등 좀 더 구체적이고 세밀한 분석이 필요함에도 기초적인 수준에서 분석이 수행되었다. 그래서 측정도 구의 신뢰도와 타당도가 정확하다고 볼 수 없다. 셋째 연구 대상자들이 요양보호사, 여성, 50~60대 노인복지기관이 상당수를 차지하는 바 모든 사회복지종사자를 대표한다고 볼 수 없다. 넷째, 본 연구는 실증적 연구로 영성과 회복탄력성, 직무만족 간에 인과성은 검증했으나 종사자들이 인식하는 영성이 어떻게 회복탄력성과 직무만족에 연결되고 영향을 미치는 심도 있는 과정과 결과를 제시하지 못했다.

The purpose of this study was to examine whether there was the difference of leg muscle isokinetic strength between Rugby Athletes and Swimmers. The subjects were 14 male athletes(Rugby Athletes 7, Swimmers 7) in C national university and they performed the isokinetic strength test of both legs at each angular speed of the 60°/sec, 180°/sec, 240°/sec by the Cybex 770. The obtained results are as follows: 1. There were significant differences between the two groups in mean values of peak torque, total work and deficit at flextion of speed of 60°/sec(p < .05). Mean values of peak torque, total work and right-left difference in Rugby athletes were significantly higher than those of swimmers. 2. There were significant differences between the two groups in mean values of peak torque and deficit at extension of speed of 60°/sec(p < .05). Mean values of peak torque and right-left difference in Rugby athletes were significantly higher than those of swimmers. 3. There were significant differences between the two groups in mean values of peak torque at flextion of speed of 180°/sec(p < .05). Mean values of peak torque in Rugby athletes were significantly higher than those of swimmers. 4. There were significant differences between the two groups in the mean values of peak torque at extension of speed of 180°/sec(p < .05). Mean values of peak torque in Rugby athletes were significantly higher than those of swimmers. 5. There were significant differences between the two groups in mean values of muscle endurance at extension of speed of 240°/sec(p < .05). Mean values of muscle endurance in swimmers were significantly higher than those of Rugby athletes. This results indicate that the Rugby athletes have much higher muscle strength and power than Swimmer. On the other hand, the endurance of Swimmer was higher than that of Rugby athletes.

To expand the utilization of domestic sprout soybeans that can not be used as sprouts, among the physiologically active substances present in sprout soybeans, the conversion to aglycone, a physiologically active form of isoflavone which acts as a vegetable estrogen, was carried out by using the mushroom mycelium. Irpex lacteus mycelia, which showed fast activity and relatively high level of isoflavone bioactive conversion in sprout soybean liquid medium, was used as a spawn for a sprout soybean solid culture. Beans were treated with steaming(SS), germinating(GS), roasting(RS) and fermented with I. lacteus mycelia 10%(v/w) for 20 days to enhance biological activities of their sprouts. The total phenolic contents, flavonoids, isoflavone, and DPPH(2,2-diphenyl-1-picrylhydra zyl) radical scavenging activity of each fermented bean were examined every 5 days for 20 days(25℃, 80%). For the application to food, free amino acid, β-glucan contents, antioxidative activity by luminol method, and cytotoxicity were measured for sprout soybeans fermented with I. lacteus mycelia on the 5th day. The quality characteristics of soymilk were investigated using sprout soybeans powder fermented with I. lacteus mycelia. The total phenolic, flavonoid, isoflavone, and radical scavenging activity of each fermented bean preparation were examined every 5 days for 20 days. The total phenolic content of SS, GS, and RS preparations was 9.61, 10.23, and 10.46 mg/g, respectively, after 15 days of fermentation. These concentrations were approximately 4-5 folds higher compared to initial levels. The total flavonoid content was 2-4 folds higher than initial levels. Of all the treatments, the isoflavone content was highest in the RS sample(6.84 mg/g). The 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity of beans fermented with I. lacteus mycelia was increased 2-8 folds after 20 days of fermentation. Antioxidant activity components were increased by fermentation of I. lacteus mycelia irrespective of soybean treatments. The correlation coefficients between antioxidant activity(DPPH) and total phenol content(TPC) was highest in all the treatments. The β-glucan contents of beans fermented with I. lacteus mycelia was increased 4∼5 folds after 5th day of fermentation, SS(3.16%), GS(3.11%), and RS(3.20%). Free amino acids were detected 23 species, there were no difference in contents according to processing method, amino acid contents of the sprout soybeans fermented with I. lacteus mycelia after 5th days, increased from 5.69 mg/g to 19.11 mg/g(SS), from 5.68 mg/g to 18.91 mg/g(GS), from 4.16 mg/g to 23.57 mg/g(RS). Volatile components were identified by Puge & trap method, SS isolated forty fractions, SS fermented with I. lacteus mycelia after 5th days(SSF) isolated forty one, GS isolated forty fractions, GS fermented with I. lacteus mycelia after 5th days(GSF) isolated forty five, RS isolated twenty-five fractions, RS fermented with I. lacteus mycelia after 5th days(RSF) isolated thirty fractions. Volatile components of sprout soybean fermented with I. lacteus mycelia decreased the ratio of 2-ethyl furan to n-hexanal, 1-hexanal, propanone, propanol and benzaldehyde by fermented mushroom mycelia, 1-octen-3-ol, 3-octanol and 5-undecene, which are typical fragrance components of mushrooms, were increased. Cell viability rate(%) investigated inhibitory effect on HT29 cell, human colorectal carcinoma cell and HepG2, human hepatocellular carcinoma cells in CCK-8 assay of sprout soybeans fermented with I. lacteus mycelia. Cell viability rate(%) in HT29 cell were significantly lower than that of blank. Cell viability rate(%) in HepG2 cell were higher than that of blank. In general, the inhibitory effect on HT29 cell of sprout soybean fermented with I. lacteus mycelia were confirmed in all samples, and cell viability was decreased with increasing concentration. Soymilk was manufactured adding sprout soybean powder fermented with I. lacteus mycelia, which was determined to be adequate in terms of isoflavone contents and sensory testing by the 7 point scale method(P<0.05), with a 10% powder added. Based on the above results, it is expected to use of I. lacteus mycelia as a new material of mushroom mycelium which gives fast growth, increase of physiological activity and change of volatile components in sprout soybean media. The concentration of the liquid-media for inoculation in the sprout soybean solid medium was obtained by inoculating a mycelium 10%(v/w), which was activated in the liquid medium for the secondary time, and cultured at 25℃, 80% for 5 days. The antioxidant activity of roasted soybeans was higher in the physiological activity test by applying the mycelium to the different processing methods(steaming, germinating, and roasting) of the soybeans. More researches of the activity of various enzymes in I. lacteus mycelia such as how to apply the processing method to food materials are needed. In addition, the future research in the application to various foods and the toxicity test for normal cells will be also needed.
