This study used a structuralized survey to examine widowed male and female senior over 65 years of age in Daegu to study how relationship with opposite sex have influence on senior`s life satisfaction. Among 250 returned survey forms, 215 forms, excluding incomplete or invalid forms, were analyzed. The following are the findings of this study: First, as for the need of relationship with opposite sex according to general and family characteristics, people in need of relationship were characterized by sex and educational level. Male and those with higher educational level showed higher need of relationship with opposite sex. Second, as for the intimacy with other sex according to general and family characteristics, more intimate people were characterized by sex, personality, and family relations. Male, the more extroverted, and those with happier families showed more intimacy with opposite sex. Third, as for the difficulties in having relationship with opposite sex according to general and family characteristics, people having difficulties in relationship were charaterized by age, personality, and health conditions. The older, the more introverted, and those with worse health conditions showed more difficulties in having relationsl1ip with opposite sex. Fourth, as for the degree of relationship with opposite sex according to general and family characteristics, people who have more active relationship were characterized by sex, monthly allowance, income, and personality. Male, those with higher monthly allowance, those with higher income, the more extroverted, and the healthier showed more active relationship with opposite sex. Fifth, as for the life satisfaction according to general and family characteristics, more satisfied people were characterized by income, personality, health conditions, and family relations. Those with higher income, the more extroverted, the healthier, and those with happier families showed higher life satisfcation. Sixth, the factors that were considerably correlated to life satisfaction include the need of relationship with opposite sex (r=0.179), intimacy with opposite sex (r=0.274), and degree of relationship with opposite sex (r=0.207). Among these factors, intimacy with opposite sex had the strongest correlation with life satisfaction. Seventh, the factors that were considerably influential on life satisfaction were income (b=0.094), personality (b=0.098), health conditions (b=0.154), family relations (b=0.126), and intimacy with opposite sex (b=0.202). Among these factors, intimacy with opposite sex was the most influential one on life satisfaction.

The purpose of this study is to determine the relationship between the health-promoting behaviors and quality of life and adjusting effects in state of health targeting the elderly who live in Korea. According to the analysis of the secondary materials from <2009 The Fourth National Health and Nutrition Examination Survey> by Korea Centers for Disease Control and Prevention on 1575 seniors in the age older than 65 years, the following conclusions were obtained. 1) The difference in health status by the general characteristics. The health status appeared to be better in male subjects, lower age, higher level of education, living with spouse, living in the residential town houses, with more economic activity and higher house hold income and with company medical insurance. 2) The quality of life by the general characteristics and health status. The variable that regulate the health status was economic activity. In both group, with and without economic activity, subjects with higher health status had better quality of life and there was a correlation found between the economic activity and health status. 3) The relationship between factors related to quality of life. In the relationship between factors related to the quality of life, it was found that the health status(r=0.493) were significantly correlated displaying better quality of life with more higher health status. 4) Factors affecting the quality of life. Factors affecting quality of life are seen as the following attributes, gender, age, housing type, economic activity, total household income, health insurance type, and health status.It was appeared that the quality of life is better in male subjects, lower age, residential apartments or townhouse housing type, economic activity, higher household income, local medical insurance, and higher health status.

정재필(Jae-Pil Chung),박정철(Jung-cheul Park) 한국정보전자통신기술학회 2021 한국정보전자통신기술학회논문지 Vol.14 No.5
본 논문은 multiplex deposition sputter system을 사용하였고 ITO 유리기판 위에 CdS 박막을 증착하여 투과율을 향상시키고 제작비용을 절감하는데 목적을 두었다. CdS 박막을 제작할 때 열처리시간을 변화시켜 태양전지를 제작할 때 우수한 조건을 찾고자 하였다. 열처리 시간 변화에 따른 두께와 면 저항은 큰 차이가 없는 것으로 관찰되었다. 비저항은 최소값 6.68에서 최대값 6.98로 측정되었다. 열처리 시간이 20분 이상하였을 때 투과율은 75% 이상으로 측정되었다. 열처리시간이 10분일 때 밴드갭은 3.665 eV이고 20분 이상은 3.713 eV로 똑같은 결과로 측정되었다. XRD를 분석한 결과 CdS의 구조는 hexagonal로 나왔으며 다른 불순물이 없이 CdS 박막 만 증착되었다. 반치폭 (FWHM)을 계산한 결과는 열처리시간을 20분으로 하였을 때 0.142로 최대값으로 측정되었고 40분일 때 0.133으로 최소값으로 측정되어 열처리 시간을 변화 주었을 때 반치폭은 큰 차이가 없었다. 입자 크기를 측정한 것으로는 열처리시간을 40분으로 하였을 때 11.65 Å으로 최대값이고 20분일 때 10.93 Å으로 최소값으로 측정되었다. This paper uses a multiplex deposition sputter system and aims to improve transmittance and reduce production costs by depositing a CdS thin film on an ITO glass substrate. When manufacturing CdS thin films, we wanted to find excellent conditions when manufacturing solar cells by changing heat treatment time. It was observed that thickness and sheet resistance were not significantly different depending on heat treatment time changes. The specific resistance was measured from a minimum of 6.68 to a maximum of 6.98. When the heat treatment time was more than 20 minutes, the transmittance was measured to be more than 75%. When the heat treatment time was 10 minutes, the bandgap was 3.665 eV and more than 20 minutes was 3.713 eV, which was measured as the same result. The XRD analysis showed that the structure of CdS was hexagonal and only CdS thin films were deposited without any other impurities. The result of calculating the FWHM was a maximum of 0.142 when the heat treatment time was 20 minutes, and a minimum of 0.133 when the heat treatment time was 40 minutes, so there was no significant difference in the FWHM when the heat treatment time was changed. The particle size was measured at 11.65 Å when the heat treatment time was 40 minutes, and at 10.93 Å when the heat treatment time was 20 minutes.

장재석(Jae-Seok Jang),정재필(Jae-Pil Chung),박정철(Jung-Cheul Park) 한국정보전자통신기술학회 2020 한국정보전자통신기술학회논문지 Vol.13 No.2
본 논문은 SET에 노출된 전자기기는 불규칙한 작동 및 출력 오류를 나타낼 수 있으므로 집적회로에서 SET 상황에 대해서 연구하였다. 폴디드 캐스코드 비교기에서 지수정류파(iexp)을 이용하여 SET 환경을 설정하였다. 비교기가 SET에 의해 어떤 영향이 있는지에 대해 실험하였다. SET현상을 발생시키지 않은 폴디드 비교기에서는 전파 지연은 0.26㎲, 이득은 0.649으로 측정되었다. SET현상을 발생시킨 폴디드 비교기에서 출력단과 가까운 MOSFET는 민감하게 측정되었으며 전파 지연은 0.36~0.37㎲,이득은 0.649로 계산되었다. 중간에 위치한 MOSFET는 0.28~0.30㎲, 이득은 0.649로 계산되었다. 폴디드 비교기에서 출력단과 가장 멀리 떨어져 있는 MOSFET는 전파지연이 0.25~0.26㎲, 이득은 0.649로 계산되었다. SET 환경에서, 폴디드 비교기에서 출력부분에 가까이 있는 MOSFET는 민감하였다. 그리고 출력부분과 멀리 떨어져 있는 MOSFET에서는 SET를 입력하지 않은 정상적인 폴디드 비교기와 같은 결과를 얻었다. This paper studied the SET situation in VLSI because the electronic devices exposed to SET can indicate irregular operation and output errors. The SET environment was established using the exponential static wave (iexp) in the fold-cascode comparator. The comparator was experimented with how it affected it by the SET. In a folded comparator that did not enter the SET situation, the propagation delay was measured at 0.26㎲ and the gain was 0.649. The MOSFET close to the output stage was measured sensitively in the folded comparator that entered the SET situation. And propagation delay was calculated from 0.36 to 0.37㎲ and the gain was 0.649. The mid-position MOSFET was calculated from 0.28 to 0.30㎲ and the gain was 0.649. The MOSFET, which is farthest from the output stage from the folded comparator, was calculated with the propagation delay between 0.25 and 0.26㎲ and the gain of 0.649. In SET situations, the MOSFET close to the output portion of the folded comparator was sensitive. And at the MOSFET far from the output, the same results were obtained as a normal folded comparator without the SET input.

Purpose: This study was done to evaluate the incidence, type of injury, medical consequences, mortality, and prognostic factors associated with stab wounds in patients who visited Kangnam Sacred Heart Hospital, Hallym University, Seoul, Korea. Methods: A retrospective analysis of the clinical data of 40 patients with abdominal stab wounds who visited Kangnam Sacred Heart Hospital, Hallym University, Seoul, Korea from January 1, 2000 to December 31, 2004. Results: 1) The most prevalent age group was patients in their the twenties to fourties (77.5% of all patients), and average age of the patients was 39.3 years. The male-to-female ratio was 2.07:1. 2) The external site of stab wounds was most commonly the periumbilcal area of the abdomen (14 cases, 33.3%). 3) The most commonly injured organs were the liver and the stomach (10 cases each, 16.9%). 4) Operations were performed on all 40 patients, with 9 (22.5%) negative operation findings. 5) Death occurred in 5 cases (12.5%). 6) The trauma indices of the death group were TRISS 51.9%, RTS 3.6 points, and APACHE II 23.0 points. 7) The average transfusion amount of the death group was 13.8 pints Conclusion: These data suggest that the transfusion amount and the trauma index of abdominal stab injuries may be statistically significant factors for predicting mortality.
