이대인,황성훈 한국건강심리학회 2026 한국심리학회지 건강 Vol.31 No.1

행동 활성화 체계(Behavioral Activation System [BAS])의 민감성은 양극성 장애의 신경생물학적 취약성으로 밝혀진 바 있다. 본 연구는 BAS가 양극성 장애 증상으로 이어지는 기제로서 이원 열정과 향유의 작용을 알아보려 했다. BAS는 보상 경험을 추구하므로, 좋아하는 일에 대한 열정으로 나타날 수 있다. 열정은 자기 체계와의 통합성에 따라 적응적 결과가 달라지는데, BAS에 따른 열정적 추구가 강박적이면 취약성이 되므로 향유될 수 없고 따라서 양극성 장애 증상의 증가로 이어질 수 있다. 반면, 열정이 자기 체계와 조화를 이루면 향유를 통해 자원화되므로 양극성 장애 증상의 감소로 이어질 수 있다고 가정하였다. 이를 검증하기 위해 사이버대생 450명에게 행동 활성화 체계 척도(BAS), 열정 척도(PS), 향유 신념 척도(SBI), 현재의 양극성 증상을 측정하는 내적 상태 척도(ISS), 과거의 조증 병력을 평가하는 양극성 스펙트럼 진단 척도(BSDS)를 온라인으로 실시하였다. SPSS Process Macro 80번 모형을 적용한 결과, 가설은 지지되었다. BAS가 강박열정으로 이어지면 향유는 감소하고, 그 결과 양극성 장애 증상의 증가에 이르는 간접효과(즉, 악화 경로)가 성립하였다. 반면에 BAS가 삶의 다른 측면과 균형을 이루는 조화열정으로 이어지면 향유를 경유하여 양극성 장애 증상의 감소에 이르는 간접효과(즉, 완화 경로)가 유의하였다. 양극성 장애의 새로운 중간 기제로서 열정과 향유가 갖는 임상적 시사점을 논의하였으며, 연구의 한계와 미래 연구의 방향을 제시하였다. Sensitivity of the Behavioral Activation System (BAS) has been identified as a neurobiological vulnerability in bipolar disorder. This study aimed to investigate how dual passion and savoring function as mechanisms through which BAS contributes to bipolar disorder symptoms. Since BAS seeks rewarding experiences, it can manifest as a passion for activities individuals love. The outcomes of this passion can be adaptive or maladaptive, depending on how well it integrates with the self-system. When the pursuit driven by BAS becomes compulsive, it becomes vulnerable, preventing savoring and potentially leading to an increase in bipolar disorder symptoms. Conversely, when passion aligns harmoniously with the self-system, it may decrease symptoms of bipolar disorder by serving as a resource through savoring. To explore this relationship, 450 cyber university students participated in an online study, completing the Behavioral Activation System Scale (BAS), Passion Scale (PS), Savoring Beliefs Inventory (SBI), Internal State Scale (ISS) to assess current bipolar symptoms, and the Bipolar Spectrum Diagnostic Scale (BSDS) to evaluate past episodes of mania. Using the SPSS process macro model 80, our hypothesis was supported. We found that when BAS leads to obsessive passion, savoring decreases, establishing an indirect pathway that worsens bipolar disorder symptoms. In contrast, when BAS fosters harmonious passion balanced with other life aspects, there is a significant indirect effect that reduces bipolar disorder symptoms through savoring. The clinical implications of passion and savoring as new mediating mechanisms in bipolar disorder are discussed, along with the study's limitations and suggestions for future research.

We report a case about a 27-year-old healthy young male who developed syncope during exercise, which was subsequently identified to be attributable to non-sustained polymorphic ventricular tachycardia (VT). Occurrence of polymorphic VT was neither related to a pro-longed QT interval nor a fixed short coupling interval. Standard examinations including echocardiography, coronary angiography, isopro -terenol infusion study, and cardiac MRI showed no structural heart disease. On the electrophysiology study, activation mapping revealed that a discrete potential preceded the premature ventricular complex (PVC) triggered polymorphic VT, which was recorded just above the pulmonary valve. After radiofrequency ablation at this area, PVC and polymorphic VT disappeared and did not recur after a 2 month fol-low up.

This study analyzed the spatio-temporal variation characteristics of major environmental factors such as primary productivity (PP), chlorophyll a, nutrients, sinking particle matters, and organic contamination and biochemical composition of surface sediment on a monthly basis for approximately 2 years around shellfish mariculture in Jaran Bay, Korea. In addition, PP in Jaran Bay was compared with that in other coastal areas and related policy plans were proposed. The average PP of the study area was high in summer and autumn with 6.43∼115.43 ㎎C m⁻² hr⁻¹ range. This was lower than that in Gamak Bay and Masan Bay, whereas higher than that in Garorim Bay and the West Sea. The PP in coastal waters, where many aquaculture farms were distributed, significantly fluctuated. The different size compositions of phytoplanktons constituting chlorophyll a slightly varied by month, and little restriction existed on the productivity of phytoplanktons owing to the depletion of nutrients. Typically, the Redfield ratio was less than 16, indicating that nitrogen was the limiting factor for the growth of phytoplanktons. The biochemical composition of particulate organic matters in the water column showed the highest carbohydrates, but lipids and protein contents were high in surface sediments. The concentration of TOC and AVS of the surface sediments was high at inside of bay, and sometimes, exceeded the environmental criteria of fishing grounds. The organic C:N ratio of sediments ranged from 8.1 to 10.4 on average. PP had the highest correlation with chlorophyll a, nitrogen and protein of particle organic materials. Recently, chlorophyll a, DIN, and DIP of water column trends tended to decrease, however, the contamination of sediments increased. Considering the annual PP of 125.9 gC m⁻² yr⁻¹ and mariculture area (oyster) of 4.97 ㎞², the annual carbon production from phytoplanktons was estimated to be about 625 tons, and the annual total wet weight of shellfish (oyster) was estimated to be about 6,250 tons. 본 논문은 남해안 자란만 패류양식어장에서 약 2년 동안 월별로 기초생산력, Chl. a, 영양염류, 입자유기물질과 퇴적물의 유기오염 정도 및 생화학 조성 등 주요 양식생물의 서식환경인자의 변동특성과 상관성 등을 분석하였다. 또한, 다른 연안 어장과 기초생산력을 비교하고 어장환경관리와 관련된 정책방안을 제시하였다. 월별 평균 기초생산력은 6.43∼115.43㎎C m⁻² hr⁻¹ 범위로 여름과 가을에 높았는데, 가막만과 마산만 보다는 낮았고, 가로림만과 서해보다는 높았으며, 대체적으로 양식장이 많이 분포한 내만은 그 변동 폭이 상대적으로 컸다. Chl. a를 구성하는 식물플랑크톤의 크기별 점유율이 시기별로 다소 차이가 있었고, 영양염의 고갈로 인한 식물플랑크톤의 생산력 제한은 거의 없었으나, 대부분 시기에 N/P비가 16 이하로 질소가 상대적으로 부족한 것으로 판단되었다. 수층 입자유기물질의 생화학적 조성은 탄수화물이 가장 높았으나, 반면 표층 퇴적물에서는 지질과 단백질 함량이 높았다. 퇴적물의 TOC와 AVS 농도는 만 안쪽에서 높았고 일부 시기에는 어장환경기준을 초과한 상태였으며, C:N 비는 평균 8.1∼10.4 범위로 나타났다. 기초생산력은 Chl. a와의 상관성이 가장 높았고, 입자물질성분 중에서는 탄소보다는 질소 및 단백질과의 상관성이 높았다. 최근 5년 동안의 수층에서의 Chl. a, DIN, DIP 농도는 감소하는 경향이었지만, 반대로 퇴적물의 오염도는 증가하는 추세였다. 자란만의 연간 기초생산력 125.9gC m⁻² yr⁻¹, 굴 양식장 면적 4.97㎞²를 고려하면 연간 식물플랑크톤으로부터 생산되는 탄소량이 약 625ton이며, 연간 굴 생산 습중량은 약 6,250ton으로 추정되었다.

The objective of this study is understanding and evaluation of temporal and spatial variation of pollutant loads by input sources for water quality management in Kamak Bay. Flow rate of rivers and ditches ranges from about 2,592-63,072㎥/d in October to 864-55,296㎥/d in January. In particular, the R2 predominated flow rate among input sources. Total COD, BOD, DIN and DIP loadings in January were about 896㎏/d, 718㎏/d, 2,152㎏/d, and 154㎏/d, respectively, which exceeded those of October. Lower POC/TOC levels are estimated in R2, and also in October. Temporal variation of pollutant loads were closely related to the human activity. Total discharging loadings of BOD, TN and TP by unit loading estimation were 4,993.0㎏/d, 2,558.7㎏/d, and 289.2㎏/d, respectively, and were mainly affected by the population. Runoff ratio of BOD was about 0.14 in January. Mean NH_4^+-N and PO_4^3--P loadings from sediment were 16.23㎎/㎡/d and 7.26㎎/㎡/d, respectively. For the improvement of water quality in this area, not only pollutant loads of rivers and ditches but also benthic flux from sediment should be reduced within the limits of the environmental capacity.

This study examined principles and techniques of efficient water quality management as well as total coastal pollutant loads and the relevant examples in the advanced countries from the viewpoints of water quality improvement and pollution control in coastal areas. The problems and improvements in an estimation of the current total pollutant loads were also pointed out. In addition, discussion was made on the relationship between total pollutant loads and environmental capacity as well as particulars requiring extensive examination on access to and study on water quality model used as prediction tool for marine environment. Furthermore, this study proposed details of and improvement plans for water quality control to be reflected and absorbed into systems and policies related to coastal water quality. In coastal areas, which are subject to total coastal pollutant loads, it is necessary to calculate pollutant loads reduction and allocation, to propose them in detail in statement in relations to new pollution sources for the corresponding projects or plans in environmental impact assessment and prior environmental review system. Also, in relations to regional plans for coastal management, the local government concerned must focus more on environmental management plan to implement data on pollution sources and pollutant loads flown into sea areas under basic jurisdiction, therefore it is required to actively respond to expansion and introduction of total coastal pollutant loads system in the future. Total coastal pollutant loads system must be expanded and executed by considering characteristics of sea area and changes in the environment of land. For pollution sources in land, the competent authorities in charge of coastal environment will need to initiatively administer supervision, monitoring activities and achieve integration and operation of the related laws by preparing legal bases for management system or adjusting the related laws.

For preliminary diagnosis on current fishing ground environment and basic information for establishment of effective and rational management policy in fisheries resources protection area, water and sediment quality and changes of total area in the 10 marine protection areas designated for fisheries resources management in Korea were assessed. Results showed that environmental quality in these areas has been degraded by pollution sources, coastal utilization and development stress, etc. The pattern and degree of contamination differed by protection areas, suggesting that it is necessary for optimum environmental management plan considering the regional characteristics. The total designated area of protection areas in 2003 changed by $-22.9{\sim}2.4%$, on average -6.4%, compared with the first year of designation; Wando-Doam Bay showd the highest increase rate (2.4%), and Hansan Bay has the highest decrease rate (-22.9%) Decrease rate of land and sea in total area showd 6.1% and 6.6%. An integrated management of environmental data in protection areas is required for systematic assessment. Therefore, the suitable environmental and information management is needed specifically considering the environment characteristics such as development and utilization conditions of land and sea area Furthermore, bemuse urbanization and industrialization threats the junctions of the protection areas, authorized ministry (MIFAFF) should develope and establish monitoring and management procedures based on the related laws.
