Block copolymer lithography has attracted great attention for emerging nanolithography since nanoscaleperiodic patterns can be easily obtained through self-assembly process without conventional top-down patterning process. Since the morphologies of self-assembled block copolymer patterns are strongly dependent on surface energy of a substrate, suitable surface modification is required. Until now, the surface modification has been studied by using random copolymer or self-assembled mono layers (SAMs). However, the research on surface modifications has been limited within several substrates such as Si-based materials. In present study, we investigated the formation of block copolymer on Au substrate by $O_2$ plasma treatment with the SAM of 3-(p-methoxy-phenyl)propyltrichloro-silane [MPTS, $CH_3OPh(CH_2)_3SiCl_3$]. After $O_2$ plasma treatment, the chemical bonding states of the surface were analyzed by X-ray photoelectron spectroscopy (XPS). The static contact angle measurement was performed to study the effects of $O_2$ plasma treatment on the formation of MPTS monolayer. The block copolymer nanotemplates formed on Au surface were analyzed by scanning electron microscopy. The results showed that the ordering of self-assembled block copolymer pattern and the formation of cylindrical nano hole arrays were enhanced dramatically by oxygen plasma treatment. Thus, the oxidation of gold surface by $O_2$ plasma treatment enables the MPTS to form the monolayer assembly leading to surface neutralization of gold substrates.

Purpose: The purpose of this study was to investigate the effect of laughter therapy and cognitive reinforcement program on self-efficacy, depression and cognitive functions of the elderly with mild cognitive impairments (MCI). Methods: The study design was a non-equivalent control group pre and posttest design. Thirty-six subjects over the age of 65 with a diagnosis of mild cognitive impairment were assigned either to a treatment or a comparison group. Data were collected from February 7 to March 27, 2012 in the dementia supporting center. An eight week treatment program that included laughter therapy coupled with a cognitive reinforcing program including hand exercise, laughter dance routine, laughter technic and cognitive training for attention, memory, orientation and execution skill. Results: MoCA-K (t=-6.86, p<.001) and Stroop test CW correct (t=-2.54, p=.008), self-efficacy (t=-3.62, p=.001) in the treatment group were significantly higher than those of the comparison group. Reported depression (t=2.29, p=.014), Stroop test CW error (U=53.50, p<.001) in the treatment group was significantly less than the comparison group. Conclusion: In this study, the treatment was effective in improving self-efficacy, cognitive function and reducing depression in the elderly with MCI.

[ $Pt/SBT/Seed/Pt/Ti/SiO_2/Si$ ]의 구조로 $SBT(SrBi_2Ta_2O_9)$ 박막을 Self-seed layer를 사용하여 R.F. Magnetron sputter를 이용하여 증착을 하였다. Self-seed layer는 기판온도 RT(room temperature)와 $600^{\circ}C$에서 두께 30 nm으로 증착하였다. Self-seed layer의 결정화 온도를 알아보기 위해 열처리온도를 변화시켰고 이를 XRD를 통하여 결정화 유무를 확인하였다. Self-seed layer 위에 증착한 SBT를 XRD와 전기적 측정을 통해 특성을 관찰하였다.

Purpose: This study examined the effects of a yoga exercise program on stress response, physical fitness and self-esteem among middle-aged women. Methods: Participants were 39 middle-aged females from District Y in Seoul who were assigned to either a treatment (N=19) or to a control group (N=20). The treatment participated three times a week in a yoga exercise program which included classes and practices. Data collection instruments included the Symptoms of Stress Inventory (1977), the Rosenberg's self-esteem scale (1965) and measurements of grip strength, flexibility and balance. The data were analyzed using the SPSS-WIN 12.0 program. Results: The treatment group had significantly lower score for stress response (t=-6.18, p<.001) and higher scores on grip strength (t=2.52, p=.018), balance (t=3.24, p=.003), and self-esteem (t=4.46, p<.001). There was no significant difference in flexibility (F=0.51, p=.479). Conclusion: The yoga exercise program can be used as a nursing intervention for middle-aged women to reduce stress and improve self-esteem.

This paper presents energy self-sufficiency simulated in municipal wastewater treatment plants (WWTPs) by adopting solar energy production systems that were simulated by varying azimuth and super-hydrophilic coating on the surface of photovoltaic (PV). Relative to the national average energy consumption in WWTPs, the employment of 100 kW PV system was simulated to achieve 2.75% of energy self-sufficiency. The simulated results suggested that the installation of PVs toward South or Southwest would produce the highest energy self-sufficiency in WWTPs. When super-hydrophilic coating was employed in the conventional PV, 5% of additional solar energy production was achievable as compared to uncoated conventional PV. When 100 kW of PV system was installed in a future test-bed site, Kihyeung Respia WWTP located in Yongin, South Korea, the energy self-sufficiency by solar power was simulated to be 1.77%. The simulated solar power production by azimuth and super-hydrophilic coating will be useful reference for practitioners in designing the solar PV systems in the WWTPs.

The purpose of the study was to identify the motives of women's appearance-management behavior, and examine how women perceived the appearance -management behavior and pursuit of ideal body image. The depth interview method was managed to five female subjects who had experiences in plastic surgery and obesity treatment. The instance analysis used in this study. The results were as follows : There were four types of women's appearance-management behavior. First, women perceived themselves by using other people's evaluation, and it was the first motive of appearance-management behavior. It shows that appearance is not based on the real self-image but is the evaluated self-image by others. Second, women were willing to suffer the pain in the plastic surgery and obesity treatment by the expectation of appearance improvement. It means the result of reducing the difference between the actual self-figure and the ideal self-image. Third, the sexual discrimination culture had an influence on appearance-management behavior. It seems the sense of male superiority spreaded over the Korean society. Lastly, women improved self-satisfaction and self-esteem through their physical appearance as an alternative method for better life.

Purpose: This study investigated the factors influencing the risk of relapse in community-dwelling adults with alcohol use disorder. Methods: This study included 122 community-dwelling individuals with alcohol use disorder who were receiving outpatient treatment at a mental health treatment hospital or were enrolled in a treatment program at the Community Addition Management Center in Gyeonggi Province. Data were collected using self-administered questionnaires from July to August 2020. Data were analyzed using descriptive statistics, independent t-test, one-way ANOVA, Pearson's correlation coefficient, and multiple regression analysis using SPSS 25.0. Results: Abstinence self-efficacy (𝛽=-.56, p<.001), social support (𝛽=-.35, p=.009), female sex (𝛽=11.29, p=.015), and a family history of alcoholism (𝛽=9.41, p=.026) were significant predictors of relapse risk, accounting for 56% of the variance (F=12.68, p<.001). Conclusion: The findings of this study suggest that abstinence self-efficacy and social support are pivotal in reducing risk of relapse in individuals with alcohol use disorder. Therefore, relevant and effective interventions focusing on enhancing abstinence self-efficacy and social support are required.

다른 근골격성 질환에서와 같이, 측두하악장애의 징후와 증상은 일시적이거나 자기 한정적(self-limiting)인 경우가 많다. 따라서 복잡한 교합 치료나 수술과 같은 비보존적, 비가역적 치료를 초기치료로 선택하는 것은 가급적 피해야 한다. 또한 자가요법, 행동 수정, 물리치료, 약물요법, 장치치료 등과 같은 보존적, 가역적 치료가 측두하악장애의 초기치료로 추천된다.
