박우철,Park, Woochul 대한가정학회 2022 Human Ecology Research(HER) Vol.60 No.1

The present study examined the effectiveness of repeated marriage checkups at intervals of six months in a Family Center in Seoul. To achieve this, the pilot study protocol (Park, 2019) was adapted, emphasizing strength-based, counseling-oriented approaches. Two couples and family therapists with master's degrees were trained and their practice was monitored to ensure program fidelity. The methods employed for the assessment of marriage checkup were an online survey, a video recording of couple problem-solving, and a clinical interview. A total of 14 couples participated in the 1st checkup, 10 of whom also completed the 2nd checkup. Couples with varying levels of marital satisfaction participated in the program. Descriptive statistics indicated gradual increases over 8-9 months in diverse indices such as marital satisfaction and relationship strength, while other indices fluctuated slightly but converged to higher levels over time. A non-parametric analysis appropriate for small samples demonstrated statistically significant increases over the 8-9 months in marital satisfaction among couples. The current study evidenced the effectiveness of repeated marriage checkups in the Family Center, which is the primary public institution for family policy and services in Korea. Repeated marriage checkups are therefore a promising way to enhance couples' relationship health and improve the family management system of the Family Center.

Objectives: It is well-established in the public health literature that marriage relationship health is a powerful predictor of physical and mental health. Inspired by the annual health checkup model in public health, marriage relationship health checkup was developed by Cordova et al.(2001). The present study applied the marriage checkup at one of the Healthy Family and Multicultural Family Support Centers which are nationwide community-based institutions delivering Korean Healthy Family Policy to the community. Method: Sixteen married couples participated in the marriage checkup. They attended the assessment session where survey, observation of problem-solving discussion, and short interview were conducted. Then, the couples participated in the feedback session two weeks later which provided results of the checkup and some recommendations for the relationship. Results: It was found that the marriage checkup couples differentiated from the couples who sought couple therapy in their level of marital adjustment and other characteristics, such as, mental health. The marriage checkup significantly improved the couples’ understanding of relationship, knowing how to improve relationship, and self-efficacy. Participants reported high level of satisfaction with the marriage checkup at the posttest. Conclusions: This study shows that the marriage checkup is a promising program for attracting new families to the center and improving their relationship health. To fit the context of Korean Healthy Family Policy, a new operation system, ‘Family Relationship Health Management System’ in which the marriage checkup plays a pivotal role of attracting and assessing couples/families is proposed.

Longitudinal studies have shown mixed findings on the association between body image dissatisfaction and self-esteem among adolescents. This study examined the longitudinal, reciprocal influences between body image dissatisfaction and self-esteem among Korean pre- and early adolescents by using nationally representative longitudinal panel data from the Korean Youth Panel Study (KYPS). Analyses based on 2,230 participants indicated that girls’ body image dissatisfaction was significantly higher than boys’. The trajectory of body image dissatisfaction increased sharply during pre- and early adolescence, but stabilized afterwards for both boys and girls. Self-esteem deteriorated rapidly initially, but began to recover as adolescent girls and boys matured. Structural equation modeling showed that reciprocal influences between body image dissatisfaction and self-esteem were detected for boys. Body image dissatisfaction among girls predicted self-esteem during the entire period, while the opposite direction from self-esteem to body image dissatisfaction emerged two years later. The present study found that, during pre- and early adolescence, body image dissatisfaction and self-esteem develop in a circular fashion by forming a vicious cycle. Implications for the development of intervention and prevention programs are discussed in consideration of age and gender.

Few studies have utilized observational methods in the field of couple research even though using self-report questionnaires is prone to the subjective biases of the reporter. This study validates the Marital Interaction Coding System-Global (MICS-G), a global version of the well-established microanalytic observational coding system, Marital Interaction Coding System (MICS). Participants in the study consisted of 30 married couples with varied levels of marital adjustment who visited one of the Healthy Family and Multicultural Family Support Centers in Seoul, either for couple therapy or the “Marriage Checkup”program. Ten-minute problem-solving discussions were rated by two undergraduate student raters who were trained for 10 hours. Interobserver agreement based on percentage agreement and intraclass correlation coefficients showed a high level of agreement between raters in establishing interrater reliability. Convergent validity was established by: correlations among marital adjustment, psychological aggression, mental health, and MICS-G categories of conflicts, validation, invalidation, facilitation, and withdrawal. MICS-G categories also were successful in discriminating between distressed and nondistressed couples, which provides evidence of discriminant validity for MICS-G. This study showed that MICS-G is a promising method for researchers to observe couple interactions in a more cost-effective way. Methodological issues and practical applications are also discussed.

Recently, the use of steering wheel mounted switches has been receiving attention. Such switches allow a driver to maintain his or her focus on the road. If the number of steering wheel integrated switches or their arrangement is improper, the advantage of using them may be diminished, and many operator errors may occur. The objective of this study was to examine how the number of steering wheel mounted switches and their arrangement interactively affected a driver’s performance. The participants were required to press a specified switch while performing a first-order tracking task. The Dial wheel-type control was more effective than a cross functional-type and touch wheel-type arrangement. The Dial wheel-type arrangement with steering wheel mounted switches provided the best performance and highest psychological rating.

Regular exercise and a certain level of physical activity reduce the mortality rate in the elderly. The purpose of this study was to investigate the effect of physical activity on the prevention of fracture in the middle aged or older in Korea. The basic data are based on the Ansan and Ansung community cohort studies of the Korean Genome and Epidemiology Study conducted by the Korea Centers for Disease Control and Prevention in 2001, and the fracture data from the third survey in 2005 to the sixth survey in 2011. The physical activity of the aged in the 40s was mostly distributed in the World Health Organization (WHO) recommended range of 7.5 to 30.0 metabolic equivalent·hr/wk, and the activity was gradually divided into the low and high groups in the 50s and 60s. In the 60s, the risk of fracture was reduced to 0.63 times compared to that of the 50s when physical activity was the recommended level (odds ratio, 0.63; p<0.001). For Korean adults, there was no significant difference in fracture incidence according to the amount of physical activity in the middle-aged people. However, for the elderly aged 60 and over, the risk of fracture decreased when the WHO recommended level of activity was performed, and the risk increased when less or more activities were performed.

현재 EMP(Electromagnetic Pulse) 방호시설의 차폐효과 성능 평가를 위해 적용하고 있는 규격들에서는 통상적으로 송신안테나를 시설 외부에 배치하고, 수신안테나를 시설 내부에 배치하여 차폐효과(Shielding Effectiveness: SE)를 측정하도록 규정하고 있다. 하지만 차폐효과 측정 시 방호시설과 외부 콘크리트 구조물 사이에 충분한 공간을 확보하지 못하는 경우, 차폐효과 측정이 불가능하게 된다. 본 논문에서는 송신안테나를 EMP 방호시설 내부에 배치하여 전자파의 차폐효과를 측정할 수 있는 시험방법을 찾기 위해 다양한 시험을 수행하였다. 차폐효과 측정 시 송수신 안테나의 위치에 따른 영향을 비교?분석하기 위해 송신안테나를 EMP 방호시설 내부에 배치하여 차폐효과를 측정한 결과, 외부에 배치했을 때보다 시험주파수 영역 10 kHz~1 GHz에서 전체적으로 평균 ±4 dB 수준의 차이가 발생하는 것으로 나타났다. EMP(Electromagnetic Pulse) protection facility was evaluated according to standard of shielding effectiveness. To comply with the standard, transmitting antenna was placed on outside of protection facility and receiving antenna was placed on inside of protection facility. However, measurement is impossible that place does not have enough space between protection facility and external concrete structure. In this paper, we performed a various of tests that put transmitting antenna inside the EMP protection facility in order to find out test method for measuring the shielding effectiveness of electromagnetic wave. Transmitting antenna was placed on inside of the EMP protection facility for measuring the shielding effectiveness to compare and analyze the impact of the position regarding to the transmitting and receiving antenna. As a result of test, in case that transmitting antenna was placed on inside of the EMP protection facility, it was found that test frequency range 10 kHz~1 GHz were occurred overall average difference of ±4 dB level.
