This study examines the usage status of legal services provided by lawyers targeting domestic consumers and investigates empirically how much online platforms that facilitate lawyer search and consultation can increase consumers' utility, and how much the lawyer legal service market will expand through this. To this end, this study applies a discrete choice demand model to the data collected through a conjoint survey to estimate the value of the lawyer search and consultation platform perceived by consumers, and estimates the effectiveness of the platform in expanding the market for lawyer legal services through a simulation method. As a result of the analysis, the relative value that consumers place on finding and consulting a lawyer using the online platform instead of being introduced to a lawyer by an acquaintance or searching for a lawyer offline is estimated to be about 70,414 won. It was found that the existence of lawyer search and consultation platforms could increase the market size of legal services by as little as 18.9% to as much as 70.2%. In particular, the platforms are expected to increase the accessibility of legal services to vulnerable groups.

박민수,김도현,이재훈,김종학 한국막학회 2019 멤브레인 Vol.29 No.6

It is a highly important problem for mankind to supply sufficient energy, which has been connected to production and supply of electricity. In terms of the problems, this study fabricated a new sort of solid polymer electrolyte membrane for supercapacitors. The fabricated electrolyte employed grafting poly(oxyethylene methacrylate) (POEM) side chain on poly(vinyl alcohol) (PVA) main chain by free-radical polymerization. It is the first time to utilize PVA-g-POEM graft copolymer as an electrolyte membrane for supercapacitor. The chain behavior of PVA was transformed by grafting POEM side chains, which was analyzed by FT-IR spectra. Also, the capacitance performances of fabricated supercapacitors were explored by cyclic voltammetry (CV), galvanostatic charge/discharge (GCD), and ragone plot. We suggest a new point, the grafting of the electrolyte of supercapacitor in this study.

During the period of August 20 to October 20, 1970 opinion polls were conducted regarding the implementation of functional division between physicians and pharmacists, prepared questionnaire sheets were distributed to the 648 pharmacists practising in Youndungp'o-gu, Seoul (as of August 20, 1970), and to 200 ordinary citizens living in the same area Questionnaire sheets were collected from 247 pharmacists and 135 ordinary citizens. As the results of studies and analysis of the questionnairs collected form the total of 382 respondent pollees, the following conclustion was reached: 1. Out of the total of 247 pharmacists who responded to the questionnaires, 61.5 per cent conditionally supported the division of labor between hpysicians and pharmacists, 25.9 per cent opposed it, and 12.6 per cent gave miscellaneous answers. 2. The groups of pharmacists who supported or opposed the division of labor were broken down by sex as follows: 61.3 per cent of male pharmacists and 62.0 per cent of female pharmacists conditionally supported it while 26.8 per cent of male pharmacists and 24.1 per cent of female pharmacists opposed it. 3. As for ordinary citizens, 41.5 per cent conditionally supported the division of labor between physicians and pharmacists, 34.8 per cent gave miscellaneous asnwers, and 23.7 per cent opposed it. 4. Mass-communications media were regarded as the most importance source of information for the pollees concering the division of laborbetween physicians and pharmacists in as much as 44.5 per cent of respondent practising pharmacists and 43.0 per cent of respondent ordinary citizens termed masscommunications media as their main sourees of information on this matter. 5. The greatest respective proportions, or 45.7 per cent of respondent practising pharmacists and 33.3 per cent of ordinary citizens, supported the step-by-step implementation of functional division between physicians and pharmacists by extending the system from selected model areas to other areas. 6. The idea of deisgnating one specific ward of the city as amodel area was supported by 43.7 per cent of respondent pollees, and the idea of implementing division of labor between physicians and pharmacists in a model area on a trial basis for one year by 41.2 per cent. These groups consituted the greatest porportions respectively. 7. As for the enforcement system of functional division 37.2 per cent of repondent physicians preferred a voluntary implementation, and 30.4 per cent preferred a mandatory implementation, while 31.1 per cent of respondent ordinary citizens gave miscellaneous answers('I don't kow") and 27.4 per cent preferred a voluntary system. 8. As for the number of pharmaceuticals to be subject to functional division between physicians and pharmacists, 38.5 per cent of respondent practising pharmacists preferred the simultaneous control of two or more kinds of pharmaceuticals (including narecotics and antibiotics), 32.8 per cent preferred the control of only narcotics, 17.0 per cent preferred the control of only antibiotics, and 11.7 preferred the control of only habitual durgs. Meanwhile, 38.5 per cent of respondent ordinary citizens wanted the control of only narcotics in the initial stage, and 28.1 per cent wanted the contro, of antitiotios first. 9. The greatest proportion or 42.9 per cent of respordent practising pharmacists said that they filled 20 cases of prescription on the daily average. As for the ratio of profit form the preparation of pharmaceuticals on the basis of prescriptions, 37.2 per cent or the greatest proportion said that such profit constituted 31 to 40 per cent of gross sales, and 14.2 per cent or the smallest proportion said that is constituted 10 to 20 per cent. 10. 46.0 per cent of respondent practising pharmacists predicted that gross income of pharmacies would decrease if functional division between physicians and pharmacists was enforced while 32.0 pear cent believed that there would be no remarkable change in their gross income. 11. 40.0 per cent of respondent practising pharmacists said that pharmaceutical companies would concentrate their development of pharmaceuticals on therapeutical preparations if functional division between physicians and pharmacists was realized, while 36.3 per cent of respondent ordinary citizens predicted that its implementation would restrain excessive advertisements on pharmaceuticals. 12. 55.9 per cent of respondent practising pharmacists opposed the designation of Yongdungp'o-gu, Seoul as a model area for the trial-basis implementation of functional division between physicians and pharmcists, while 32.0 per cent supported it and 12.1 per cent gave miscellaneous answers. On the basis of the above results of survey, the following matters are considered prerequisite tofunctional division between physicians and pharmacists in Korea 1. Functional division between physicians and pharmacists Should be implemented after these social conditions are achieved the elimination of doctor-less areas and pharmacists-less areas, and the implementation of the medical insurance system. 2. In should be implemented after occupational functions are systematically classfied between physicians and pharmacists regarding their in come and professional skills. 3. Adequate legal protection and a definite government policy are necessary for fair distribution of income between physicians and pharmacists. Parmaceutical items to be subject to its enforcement should be designated step by step. The System should then be implemented gradually through trial implementation in model districts.

박민수,정연주,김영택 한국해안,해양공학회 2022 한국해안해양공학회 논문집 Vol.34 No.6

New businesses such as marine leisure and floating construction have recently flourished on the coast. As a result, consideration is given to a floating structure appropriate for marine environments. In this study, we applied a damping plate to increase the stability of a hybrid floating structure that was expanded by vertical and horizontal stacking of mobile unit modules. In the numerical analysis using ANSYS AQWA, the behavioral characteristics of the floating structure were analyzed according to the length change of the damping plate. However, the wave forces acting on a floating structure are excessively calculated by the resonance of fluid surrounded by the structure in the numerical analysis using potential flow. Therefore, we used the damping zone option of the ANSYS AQWA in the frequency domain analysis. 최근 연안에서 해상관광레저, 플로팅 건축 등의 사업발굴이 활발히 진행 중에 있어 해상조건에 적합한 부유식 구조물의 필요성이 대두되고 있다. 본 연구에서는 육상 이동이 가능한 단위 모듈의 수직 및 수평 적층으로 확장된 하이브리드 부유식 구조물의 안정성을 향상시키기 위해 수평감쇠판을 적용하였다. 적용된 수평감쇠판의 길이변화에 따른 하이브리드 부유식 구조물의 거동 특성을 상용 프로그램인 ANSYS AQWA를 이용하여 분석하였다. 하지만 제안된 하이브리드 부유식 구조물의 경우 구조물에 의해 둘러싸인 유체영역이 존재하고 이로 인해 특정 주기에서 공진이 발생할 가능성이 있다. 따라서 구조물에 의해 둘러싸인 유체영역에 ANSYS AQWA에서 제공되는 감쇠존 효과를 고려하여 부유식 구조물의 거동 특성을 주파수 영역 수치해석을 통해 면밀하게 분석하였다.

The design and the construction were carried out by installing new caissons on the back or the front of existing caissons to increase the structural stability of caisson breakwaters. In this study, we used the ANSYS AQWA program to analyze the wave forces acting on individual caissons according to the effects of wave-structure interaction when new caissons were additionally installed on existing caisson breakwaters. The wave force characteristics acting on the individual caisson were analyzed according to the distance among caissons in frequency domain analysis. In addition, the dynamic wave force characteristics were closely examined on the basis of the frequency at which the unusual distribution of wave forces occurs in irregular wave conditions using time domain analysis. 기존 케이슨방파제의 전면 또는 후면에 추가로 케이슨을 설치하여 구조물의 안정성을 향상시키기 위한 설계 및 시공사례가 보고되고 있다. 본 연구에서는 상용프로그램인 ANSYS AQWA를 이용하여 신규 케이슨이 추가로설치되는 경우 입사하는 파랑과 케이슨들간의 상호작용 영향에 의해 개별 케이슨에 작용하는 파력 특성을 분석하였다. 앞뒤 케이슨간의 간격변화에 따른 개별 케이슨에 작용하는 파력 특성을 주파수영역에서 수치해석을 수행하였다. 그리고 특이한 파력분포 특성이 발생되는 주파수에 대해서는 불규칙파 조건에서의 시간영역 수치해석을 통해 개별케이슨에 작용하는 동적파력 특성을 면밀하게 검토하였다.

박민수,최충석 한국화재소방학회 2020 한국화재소방학회논문지 Vol.34 No.4

This study analyzed flame growth characteristics and carbonization patterns when floor materials were burned verticallyusing a needle flame produced for this study. It was found that PVC flooring was fire retardant and the area under directflame contracted inward. Vertical combustion causes solidification in the form of a lump at the bottom and also generatessoot in a pattern that progresses upwards. This study found that laminated flooring exhibited no fire retarding characteristicsand that the laminated layer of its upper surface was destroyed by fire, causing irregular delamination. The carbonizationranges at the left and right sides were determined to be symmetrical. A vertical combustion test of a sample carpet showedthat it exhibited no fire-retarding characteristics. It was observed that if heat accumulated in the carpet, the flame formedan ascending air current, and that when flammable materials were present around the flame, they further accelerated thediffusion of the flame. The carbonization pattern at the carpet surface exposed to direct flame revealed that the carpetsurface had melted and had flown downwards and that many tiny holes formed on it. 자체 제작된 니들 플레임을 이용하여 바닥재를 수직 연소시켰을 때의 화염의 성장 특성 및 탄화 패턴을 해석하였다. PVC 장판은 난연성이 있는 것으로 확인되었고, 직사 화염을 받은 곳은 안쪽으로 수축되는 패턴을 나타냈다. 수직 연소가 진행되면 하부에 망울 형태의 고형화가 발생하며, 그을음은 상부로 성장하는 패턴이 형성된다. 강화마루는 난연성이 없는 것으로 확인되었으며, 상부 표면인 라미네이트층의 소실과 불규칙적인 박리가 형성되는 것을 알수 있다. 좌측면과 우측면의 탄화의 범위는 대칭적 구조를 나타내는 것으로 해석된다. 강화마루와 마찬가지로 카펫은 수직 연소 실험에서 난연성이 없는 것이 확인되었다. 카펫에 축열이 형성되면 화염은 상승기류를 형성하고, 주변에 가연성 물질이 있을 때 화염의 확산은 더욱 촉진하는 것을 알 수 있었다. 직사화염을 받은 카펫 표면의 탄화 패턴은 표면이 용융되어 흘러내렸을 뿐만 아니라 작은 구멍이 다수 발생되는 것을 알 수 있다.

박민수 한국해안,해양공학회 2019 한국해안해양공학회 논문집 Vol.31 No.6

In order to increse the stability of old caissons, the design and the construction are performed by installation of new caissons on the back of or on the front of old caissons. In this study, we use the eigenfunction expasnion method to analyze the characteristics of wave forces when new circular caissons are installed on the back of old caissons. The comparison of numerical results between eigenfunction expansion method and ANSYS AQWA is made and the wave force acting on each circular caisson is calculated by considering the wave-structure interaction effect. 기존 케이슨의 안정성을 높이기 위해 신규 케이슨을 기존 케이슨 전면 또는 후면에 추가로 설치하여 보강 하는 설계 및 시공사례가 발생되고 있다. 본 연구에서는 고유함수전개법을 이용하여 원형케이슨으로 구성된 기존 방 파제 후면에 신규 원형케이슨이 설치될 경우 각 원형케이슨에 작용하는 파력특성을 분석하였다. 수치해석의 신뢰성 을 확보하기 위해 상용화 프로그램인 ANSYS AQWA의 수치 해석결과와 비교를 수행하였으며, 원형 케이슨 추가 설치에 따른 파와 구조물의 상호작용 영향을 고려하여 각 원형케이슨에 작용하는 파력을 산출하였다.

용, 바람, 구름: 명대 국정 운영과 황제 권력

박민수 한국역사연구회 2024 역사와 현실 Vol.- No.131

This paper offers a comprehensive examination of the Ming Dynasty, focusing on two key areas : the evolution of its political history and the various facets of the Ming Emperor’s authority. The early Ming emperors, beginning with Ming Taizu Zhu Yuanzhang, also known as the Hongwu Emperor, established autocratic power through strong charisma and extensive institutional reforms. The imperial power’s legitimacy was further cemented internally and externally by the Yongle Emperor’s strategic relocation of the capital to Beijing, accompanied by his proactive foreign policies. Initially, the cabinet and eunuchs were established as private entities to support imperial power. However, they gradually expanded their influence, bolstered by the emperor’s support and protection. Key to this expansion was the cabinet’s ability to draft suggested rescripts – ‘piaoyi’ (票擬) –and the eunuchs’ practice of applying red ink annotations to memorials – ‘pihong’ (批紅). These practices became institutionalized mechanisms, allowing officials and eunuchs to influence imperial policy decisions. However, the emergence of less governance-focused emperors during the middle period of the Ming Dynasty disrupted the balance between the cabinet and the eunuchs, leading to escalating political chaos. This period was marked by a growing clash between the private desires of imperial power, often manifested through the eunuchs, and the public ideals held by the bureaucrats. The ensuing debate over the ‘public’ and ‘private’ aspects of imperial power ultimately led to a state of national governance chaos in the late Ming Dynasty. Despite efforts at reform by Zhang Juzheng and resistance from the Donglin Faction, the crisis of imperial power in the Ming Dynasty could not be resolved, culminating in the empire’s eventual collapse.

환상을 통해 드러나는 폭력과 위반 - 옌롄커의 『 일광유년(日光流年)』 연구 -

박민수 중국인문학회 2024 중국인문과학 Vol.- No.87

The theme that penetrates the "『日光流年』" is 'death'. To avoid 'death' is to protect 'life' or face 'death' proudly. As such, the topic of ‘三姓村’ is 'life and death', one big 'conflict' penetrating the entire novel. Compared to other people, it has a limited lifespan of 40 years, and no one exceeded this. Delaying the time of 'death', in other words, and increasing the time of 'life', is a task to be solved by ‘三姓村’ and the driving force of the novel. Conflict can be said to reveal the character's character and values and to grasp the subject of the novel through confrontation and conflict between characters and characters, or characters and groups and classes. In this article, I would like to focus on the conflict in the novel. First, in "『日光 流年』", conflict is 'life and death', that is, increasing the lifespan of the villagers. It is the village's 'village chief' who leads the business of increasing life expectancy. In an environment of life and death, the authority of the 'village chief' is absolute. For the villagers, his attitude appears as a sacrificial spirit and extreme violence. The spirit of sacrifice is the distribution of grains to famine. Violence is more powerful in the common goal of living over the age of 40. Especially in the value of the group, individual sacrifice is taken for granted and expressed violently. However, on the one hand, the constant challenge of the death of the villagers is the struggle for life and consideration of human development. It tries to explore human desire through the 'village chief'. Second, through conflict analysis in the novel, it was revealed that it criticized the barbaric political violence in modern Chinese history. And it was revealed that the 'village chief' and modern Chinese history in the novel are metaphors for the political disaster and those in power that occurred in modern China. Third, we explored the violent, anti-human, and anti-ethics actions of the 'village chief' to prevent disasters. In addition, it was revealed that the project to live a long life is a utopian fantasy that cannot be realized. Fourth, in the novel, the life of the protagonist '司马蓝' unfolds in reverse. I would like to analyze why I chose this narrative structure, focusing on the love of '司马 蓝'. The desire for '司马蓝' to become a 'village chief' conflicts with the ethical norms of the villagers, and at the same time, love with '蓝四十' has not been achieved. I want to explore the restoration of humanity through the love of the two through the novel.
