본 연구는 발달적 위기에 놓여있는 중년여성의 피로도와 스트레스 저항력 그리고 정서와의 상관관계를 알아보기 위하여 뇌신경 생리학적 지표인 뇌파 측정을 이용하여 분석해 보고자 하였다. 2005년 3월부터 2009년 6월까지 한국정신과학연구소에 뇌파 측정을 의뢰한 우리나라 중년여성 4403명(35세~65세)을 기준으로 선정된 뇌기능 지수(긴장도, 항스트레스지수, 정서지수)를 시계열 선형분석과 상관분석으로 한 결과 중년여성의 피로도, 스트레스 저항력 그리고 정서에는 밀접한 관계가 있었다. 그러므로 사회적으로나 가정적으로 성숙하고 책임감 있는 중년여성의 역할이 필요한 현대사회에서, 중년기의 심리적 생리적 문제에 적극적으로 대처하는 것이 개인생활은 물론 가족의 원만한 기능과 안녕을 유지, 증진하는데 반드시 필요하다.

Recently, feasible services in ubiquitous computing environment are commonly based on context -aware computing. With the concept of context-awareness we can imagine more effective way to measure human being's daily stress and provide anti-stress services. Our study introduces logical and methodological approach to manage the stress through the development of stress index. From the practical perspectives, we also designed a business model for u-SMC, which is a profitable organization specialized in providing stress measurement services and personalized anti-stress services by utilizing the stress index model.

일반적으로 사람은 육체적, 정신적 그리고 심리적 자극에 반응할 경우 스트레스(Stress)가 유발된다. 이 스트레스는 정상적인 업무수행 뿐만 아니라 건강에 악영향을 미칠 수 있고, 피로누적의 한 원인이 되기 한다. 특히 열악한 환경에서 직무를 수행하는 선원에게 있어서 스트레스는 해양사고의 직간접적인 요인이 될 수 있기 때문에 선박 인적자원관리의 한 측면으로 중요하게 다루어질 필요가 있다. 이 연구는 해운기업이 선원의 인사 및 안전관리 시스템에 활용할 수 있는 선원용 스트레스 평가도구를 개발하기 위한 것으로, 기본영역, 가족생활영역, 재정영역, 직업 및 선박생활영역에 대하여 90개의 항목으로 구성된 설문도구를 개발하여 설문조사를 수행하였고, Holmes & Rahe의 사회적응평가도구의 항목 및 평가지수와 비교분석하여 한국 선원의 문화적 차이를 고려한 설문도구를 개발하기 위한 기초적 연구를 수행하였다.

The purpose of this paper is to analyze thermal sensation which is measured by human physioclimatic reactions in South Korea. Relationships between Temperature-Humidity Index(THI) and human thermal sensation scale are derived from a questionnaire, which investigates degree of volunteer's thermal sensation with respect to each biometeorological condition. Analyses of these empirical relationships make it possible to calculate thermal sensational indices and to classify bioclimatic types for individual weather stations based on long-term(1971-2000) averages of monthly temperature and humidity data. A generalized annual physioclimatic maps for each Annual Cumulative Thermal Sensation Index for the 68 stations are constructed to show men tend to feel in various areas. The Monthly thermal sensations are affected by latitude, altitude, orographic effects and systems of airmasses. The Annual Cumulative Thermal sensations are increasing towards northern areas and inland, and that the major factors are largely derived from cold stress in winter. The Annual Physioclimatic Types are grouped 8 climatic types(M, ES, M-ES, M-S, W-ES, C-ES, C-M, C-M-ES) according to climatic stress. Results of this study can be applied for evaluation of thermal environment in our daily activities, and for searching relevant sports training-sites, climatherapy etc.

This study analyzed the correlation between stress measurements calculated through HRV signals and thyroid function test items. 181 healthy adults without disease who visited Clinic K were the subjects of this study. Stress resistance (SR) and stress index (SI) were calculated using the acquired HRV signal, and TSH, Free T4, and T3 were used as thyroid function test items. For the measured values, the relationship between each item was statistically analyzed through Pearson correlation analysis. From the results, it was confirmed that Free T4 and SR had a positive correlation (r=0.18) and a negative correlation with SI (r=-0.16). Through this, it was confirmed that there is a significant relationship between thyroid function and HRV signal.

강우 변동성과 기온의 증가 추세로 전 세계 여러 지역에서 가뭄의 빈도, 지속기간, 심각도, 영향면적이 증가하고 있다. 기후변화로 인한 극심한 가뭄은 담수 생태계에 심각한 결과를 가져올 수 있으며, 이는 중대한 사회적 경제적 영향을 미칠 수 있다. 본 연구에서는 낙동강 수질오염총량관리 단위유역에서 기상학적 가뭄 발생 시 하천 수생태계가 받는 수질 스트레스 위험도가 식별된다. 기상학적 가뭄은 표준강수지수(SPI)로 한정되며 하천 수질은 BOD로 한정되어 분석이 수행된다. 또한, 본 연구에서는 하천의 수질 스트레스를 식별하기 위하여 가뭄 시 환경영향 지수인 Environmental Drought Condition Index-water quality(EDCI-wq)를 제안한다. EDCI-wq는 기상학적 가뭄이 발생하였을 때 수생태계가 평상시 대비 스트레스를 받을 가능성을 표현한 지수이다. 최종적으로 산정된 EDCI-wq를 기반으로 하천 구간별로 관심, 주의, 경계, 심각 단계 구분 기준을 마련하여 기상학적 가뭄 발생 시 하천 수생태계가 받는 수질 스트레스를 단계적으로 식별할 수 있는 수질 스트레스 위험도 지도가 작성된다.

This study was conducted to evaluate the effects of an abdominal obesity management program on dietary intake, stress index, and waist to hip ratio (WHR) in abdominally obese women. The subjects were 195 adult abdominally obese women (WHR ${\geq}$ 0.80) who had been participating in a nutrition education (total of nine times) and dietary habits and life style modification programs (total of six times) for 12 weeks. The abdominal obesity management program focused on the nutrition provided by breakfast, lunch, and dinner, proper dietary habits, and practices to improve life style. The subjects were divided into a WHR decrease group and a WHR increase group according to changes in the WHR. Daily nutrient intake was assessed with a 3-day food record, body measurements and blood vessel age, stress index, and a health index that were measured at baseline and after 12 weeks. After the intervention, weight, waist circumference, hip circumference, WHR, and body mass index (BMI) decreased significantly in the WHR decrease group. Energy intake increased from 1486.2 kcal to 1541.4 kcal with a significant improvement in nutrient density for animal protein, total fat, animal fat, fiber, calcium, phosphorus, zinc, vitamin $B_6$, vitamin C, vitamin E, and saturated fatty acids in the WHR decrease group. Additionally, dietary diversity increased significantly in the WHR decrease group compared to that in the WHR increase group. The WHR decrease group showed a significant improvement in the stress and health indices. Changes in WHR were correlated with changes in nutrient intake (animal protein, total fat, animal fat, plant fat, fiber, calcium, iron, potassium, vitamin A, vitamin $B_2$, vitamin $B_6$, vitamin C, and folate) and medical index profiles (stress and indices) adjusted for age, birth status, baseline BMI, and baseline WHR. These results show that an abdominal obesity management program was effective not only for reducing the WHR but also to improve dietary intake and the stress index in abdominally obese women.

현재 우리나라는 보유 또는 지배선박이 약 1,000척, 3천만G/T로 노르웨이에 이어 세계 6위의 해운강국으로 성장하였다. 그리고 수많은 사관과 부원들이 다양한 선박에 승선하고 있으며 해운산업이 성장할수록 더 많은 선원들이 선박에 근무할 것으로 예상된다. 그러나 IMO와 ILO 등에서는 선원들의 선박근무환경 및 휴식 등에 관해서 최소한만을 규정하고 있고, 이로 인하여 선원들이 높은 노동 강도에 시달리게 되고 피로와 스트레스가 누적되어 해양사고의 한 원인이 되고 있는 실정이다. 이 연구에서는 각 선박의 고유 특성과 운항환경 등으로 고려한 선박의 근무강도를 평가할 수 있는 요소와 지수를 개발하기 위하여 선박에 장기간 승선한 경험이 있는 응답자로 하여금 각 평가요소에 대하여 주관적으로 인지하는 선박의 근무강도를 평가하도록 하였다. 이 평가요소와 지수를 기반으로 선원들을 각 선원의 특성과 여건에 맞는 선박에 배정함으로서 선원들의 피로와 스트레스를 경감시켜 해양사고의 예방에 기여할 수 있을 것으로 예상된다.

The purpose of this study was to examine the relationships between depression, stress, self-esteem, oral health-related quality of life (OHIP-14) in middle-aged women. Data were as collected by self-reported questionnaires from 205 middle-age women. The instruments were the Center for Epidemiologic Studies Depression scale (CES-D), Brief Encounter Psychosocial Instrument (BEPSI), Self-Esteem Scale (SES). The data were analyzed using t-test, one-way ANOVA, Pearson correlation coefficients and multiple regression with IBM SPSS Statistics ver. 21.0. Pearson correlation coefficient analysis found that oral health impact profile (OHIP) was significantly associated with depression (r=-0.560, p<0.001), stress (r=-0.595, p<0.001), self-esteem (r=0.522, p<0.001). The OHIP was explained 39.4% by stress (${\beta}$=-0.362, p<0.001), self-esteem (${\beta}$=0.203, p=0.009) using multiple regression analysis. These results indicate that the intervention program of oral health promotion for community-middle- aged women is needed from now on.

The purpose of this study was to evaluate the association between industrial workers' job stress and oral health related quality of life and subjective happiness. The subjects of this study were 228 workers, from August 8 to September 2, 2016, research tool was the structured, anonymous, self-administrated questionnaire. The data were analyzed by SPSSWIN 18.0, t-test and one way ANOVA, Scheffe' post hoc test, Pearson correlation and Hierarchial multiple regression. Negative correlation was found between job stress and OHIP-14 and between job stress and subjective happiness and positive correlation was found between OHIP-14 and subjective happiness. As for the explanatory power of the independent variables affecting subjective happiness, gender, self-reported living status, self-reported general health, dental checkups, and job stress were significant variables. It is therefore necessary to run an industrial oral intervention program on a regular basis and cope positively with stress with the objective of helping workers improve their subjective happiness.
