The purpose of this study is to analyze whether a group reminiscence program is effective in improving self-esteem and reducing depression in the elderly. The subjects of the study were 20 men and women aged 65 or older who used a senior welfare center located in N City. They were randomly assigned to the experimental group (n=10) and control group (n=10). Self-esteem and Korean Depression Scale (GDS-K) were used as measurement tools to verify the effectiveness of the program. The experimental group conducted a total of 10 sessions, once a week, for 80 minutes each. A group counseling program was implemented for the experimental group, and no measures were taken for the control group during the same period. To verify the effectiveness of this program, the SPSS 21.0 statistical program was used to calculate the mean and standard deviation of the pre- and post-tests for each group and conduct an independent samples t-test. As a result of the study, the experimental group that implemented the program significantly improved self-esteem and significantly decreased depression compared to the control group. Based on these results, the significance and limitations of the study were discussed.

The purpose of this study done by group-based application was to clarify the effect of cognitive health promotion program depending on group size. Data of 377 elderly who had a normal cognitive function was obtained through each health centers located in Incheon city. In the result, there was significant effects on cognition and quality of life, but no effect on depression. Also theres was no difference of the program's effect depending the group sizes. The result of this study would support the program of this study could be provided to more elderly by group-based application.

The purpose of the study was to develop a death education program and evaluate the effectiveness of the program on the attitudes toward death, suicidal ideation and meaning in life among university students. The participants were 24 students, 11 in the experimental group and 13 in the control group. The death education program was developed and practiced with the experimental group for 8 sessions. The death education program reduced the negative attitude significantly toward death, and increased the meaning in life significantly in the experimental group. Suicidal ideation was also decreased but it was not statistically significant. There were significant differences in attitude toward death and meaning in life between the experimental and control group but not in suicidal ideation.

The Internet is being utilized as a means of communication channel for science information. In this study, an experiment was conducted against college students, in which participants were assigned to one of the following four conditions: source status(professor, student) x social categorization(in-group, out-group). When the participants finished reading an online news article, perceived usefulness of and attitude toward the science technology were measured. The results show that the effect of source expertise on perceived usefulness was moderated by social categorization.

Salix koriyanagi is a deciduous shrub and native to Korea. The spatial distribution of multilocus allelic frequencies and geographical distances of the natural population in upper swampy area at the Namgang River in Korea were studied. The species showed a significant positive and negative spatial autocorrelation according to geographical distances as measured by Moran's I. Genetic similarity of individuals was found among subpopulations at up to a scale of a 12 m distance, and this was partly due to a combination of allelic frequencies, and therefore, a significant spatial autocorrelation was composed of a scale of 12 m intervals. Within S. koriyanagi in swampy area at the Namgang River, a strong spatial structure was observed for allozyme markers, indicating a migration within subpopulations.

본 연구에서는 대량 맞춤화(Mass Customization)에 적절한 의류 제품 디자인 프로세스를 연구하기 위하여, 맞춤화 정도를 달리한 두 가지의 디자인 프로세스 모형을 제안하고 이를 종래의 대량 생산형 디자인 프로세스와 비교 고찰함으로써 보다 효과적인 디자인 프로세스의 방향을 모색하였다. 대량 맞춤화형 제품에 대한 선호도가 높은 집단이 전체 응답자의 과반수 이상을 차지하였으며 맞춤화가 가장 심화된 디자인 프로세스 모형에서의 디자인 만족도가 높았으므로, 의류 제품에 있어 대량 맞춤화형 디자인 프로세스에 대한 소비자 수용 가능성이 있는 것으로 사료되었다. 또한 전체 응답자를 대상으로 하여 디자인 요소별 선호도를 분석해 본 결과, 대량 맞춤화형 디자인 프로세스에서 색채가 중요한 요인으로 분석되어 소비자에게 색채를 선택할 수 있는 기회를 주는 것이 중요함을 알 수 있었다. 연구집단으로 선정한 '대량 맞춤화형 제품에 대한 선호도가 높은 집단'의 경우 전체 응답자 집단에 비하여 소재 변수를 의미 있게 평가하는 것으로 나타났다. 또한 전체 응답자 집단과 연구집단의 경우 모두 스타일이 가장 중요하며 통계적으로 의미 있는 영향을 미치는 디자인 요소인 것으로 나타났다. 결론적으로 본 연구를 통하여 소비자의 요구를 반영할 수 있는 대량 맞춤화형 의류 제품의 수용 가능성과 이에 적합한 의류 제품 디자인 프로세스의 방향을 모색해 볼 수 있었다.

One of the important fields for heuristics algorithm is how to balance between Intensificationand Diversification. Ant Colony System(ACS) is a new meta heuristics algorithm to solve hard combinatorial optimization problem. It is a population based approach that uses exploitation of positive feedback as well as greedy search. It was first proposed for tackling the well known Traveling Salesman Problem(TSP). In this paper, we propose Multi Colony Interaction Ant Model that achieves positive negative interaction through elite strategy divided by intensification strategy and diversification strategy to improve the performance of original ACS. And, we apply multi colony interaction ant model by this proposed elite strategy to TSP and compares with original ACS method for the performance.

In interim analysis, group sequential tests are widely used for the ethical, scientific, and economic reasons. In this paper, we propose the group sequential tests using both type I and type II error spending rate functions when the response variable is discrete, especially binomial distribution, in the interim analysis. In addition, we propose new error spending rate function which covers the formerly proposed. Our method has good property that is flexible, fast and easily applicable. A numerical simulations are carried out to evaluate our method and it shows good performance.

본 연구는 모바일기기 사용자들의 특성을 알아보고자 사용자들의 모바일기기 휴대의도에 영향을 미치는 변수들을 기준으로 사용자들을 세분화 하였다. 선행문헌연구를 통해 휴대의도에 영향을 미치는 변수들로 유용성, 즐거움, 불안감과 사회적 영향인 주관적 규범, 가시성, 이미지, 자발성 등을 도출하였다. 자료수집을 위해 서울 및 수도권에 거주하고 휴대폰이나 노트북, PDA등을 소유한 대학생 및 대학원생과 직장인들을 대상으로 설문조사를 실시하였다. 휴대의도의 영향변수 분석결과 불안감과 주관적 규범이 휴대의도에 유의한 양의 영향을 미치는 것으로 검증되었다. 이를 기준변수로 군집분석을 통해 전체 표본을 네 집단으로 세분화 하였다. 세분화 결과 군집 1은 주관적 규범만이 영향을 미치는 집단으로 전체응답의 36.25%를 차지하고 있으며, 군집 2는 불안감만이 영향을 미치는 집단으로 전체 응답의 13.44%를 구성하는 것으로 나타났다. 군집 3은 불안감과 주관적 규범 모두 영향을 미치지 않는 집단으로서 전체 응답에서 19.06%를 차지하고 마지막으로 군집 4는 불안감과 주관적 규범 모두 영향을 미치는 집단으로 전체응답의 31.25%를 구성하는 것으로 나타났다.
