The purpose of this study was to develop a program that reduces adolescent delinquency and enhances adolescents' social problem-solving, emotional regulation, and self-control skills and to assess the effectiveness of the program. The program was administered in the form of a role-playing game ("RPG") to increase the participants' motivation to participate in and the effectiveness of the therapy. The subjects in this study were 36 adolescents who engaged in delinquent behavior and their 18 homeroom teachers in middle schools located in Seoul and Gyeonggi Province. The subjects were randomly assigned to the experimental group or the comparison group. The experimental group received the proposed RPG-based cognitive behavioral group therapy while comparison group received problem-solving group therapy. Teachers in the experimental group were educated about how to guide their students following each therapy session while teachers in the comparison group did not receive any education. The dependent variables in this study were incidences of delinquent behavior and social problem-solving, emotional regulation, and self-control skill level. Each variable was assessed before treatment, immediately after the end of the full treatment program, and two months after the end of the full treatment program. At the end of the full treatment program, the experimental group engaged statistically significantly in fewer delinquent behaviors and displayed statistically significantly higher levels of social problem-solving, emotional regulation, and self-control skills than the comparison group. These differences persisted until the assessment two months after the end of the full treatment program. Moreover, the experimental group reported higher levels of satisfaction with the treatment program than the comparison group. The findings of this study suggest that this RPG-based cognitive behavioral group therapy program is effective at reducing adolescent delinquency, improving adolescents' social and emotional management techniques and strategies for avoiding delinquency, and in motivating delinquent adolescents to engage more actively in treatment.

This study examined the effects of 1:1 online coaching for college students on self-directed learning, learning motivation and time management. The coaching program consisted of motivation, behavior and cognitive control, which are sub-factors of self-directed learning. Total of 7 sessions(80 minutes per session) were progressed. Seven participants who wanted coaching, out of the total 16 participants, were assigned to the experimental group. A non-equal control group experimental design was applied. Dependent variables were measured by questionnaire before and after the coaching, and satisfaction survey and post-interview were also conducted after the coaching. ANCOVA was adopted to test the effectiveness of the program. The statistical results indicated that the learning coaching of this study has positive effect on self-directed learning and learning motivation of university students, and has partially positive effect on time management. In addition, the mean of satisfaction survey was 4.85 and participants showed positive responses on the program.

본 논문의 목적은 첫째, 자본자유화로 인해 통화공급 구조가 이미 균형에서 이탈하여 심각한 수준의 불균형 상해에 있다는 점을 실증적으로 입증하고자 한다. 둘째, 자본유입에 따른 정책조정 비용을 감안한 통화정책 모형을 통해 주장에 대한 이론적 근거를 제시하고, 정책 조절에 수반되는 손실비용(損失費用)과 Mundell의 $\ulcorner$할당 문제(割當 問題)$\lrcorner$를 다시 조명해 보고자 한다. 세째, 자본유입에 따르는 문제점들을 해결할 수 있는 정책방안들을 Modigliani ar Miller의 명제(命題)에 입각한 새로운 각도에서 합리적 인 증시정책을 모색해 보고자 한다. 분석의 이론적 틀로서는 자본유입에 따라 수반되는 불확실성하의 정책조절 비용을 감안한 손실비용 최소화(loss cost minimization)를 통해, 통화 당국자는 총통화량을 정책적으로 내정된 목표값에 수렴시킨다고 가정하였다. 다른 한편, 자본유입에 따르는 문제점들을 통화시장에만 제한시키는 부분적(部分的) 균형분석(均衡分析) 대신, 이를 증권시장으로 직접 연계시켜 두 시장으로 확장된 틀을 활용하였다. 본 논문의 연구방법은 다음 두가지 측면의 접근식을 따랐다. 첫째, 자본자유화정책의 특성을 살펴보기 위해, 자본자유화 시점을 기준으로 삼아 과거 자본통제 시대의 $\ulcorner$사후적(事後的)인 중화정책(中和政策)$\lrcorner$에 의존하는 $\ulcorner$소극적(消極的)인 증권정책(證券政策)$\lrcorner$과 자본자유화시대의 $\ulcorner$사전적(事前的)인 상살정책(相殺政策)$\lrcorner$에 의한 $\ulcorner$거시적(巨視的)인 증권정책(證券政策)$\lrcorner$을 통해 고찰하는 비교분석론에 입각한 접근식을 택했다. 둘째, 외국자본의 유입동기(流入動機)를 문제해결의 시발점으로 삼아 이를 새로운 개방정책과 직결시켜 문제해결의 실마리를 풀어 보려는 선험적(先驗的) 접근식(接近式)을 택했다.

우리나라는 토지이용이 고도화 되어 있고 상수원에 각종 오염시설이 이미 입지해 있으며 개발압력이 가중되고 있는 현실을 고려해 볼 때 환경기초시설 확충 및 배출기준 강화 등 사후적 관리방법으로는 상수원의 수질개선에 한계가 있다. 그리고 상수원수질보전을 위한 기존의 토지이용 규제정책도 일정 규모 이하는 규제 대상에서 제외되어 소규모 시설에 대한 효율적 규제가 안 되고 있을 뿐만 아니라, 토지이용 규제에 의한 주민의 재산권 제한으로 민원도 계속되고 있다. 따라서 오염원의 총량적인 증가에 효율적으로 대처하고 주민이 스스로 오염원 총량발생을 억제함과 동시에 환경친화적으로 지역을 개발할 수 있는 새로운 수질관리 기법이 도입될 필요가 있다. 이에 본 연구에서는 섬진강을 대상하천으로 각 배수구역별 유황분석을 실시하고, 오염원조사, 부하량 산정, 수질모델링의 불확실성등 안전율을 고려하여, 오염원 총량관리 기본방침을 기준으로 오염총량관리대상 오염물질의 종류인 생물학적 산소요구량(BOD)에 대하여 2006년과 2011년의 장래수질예측을 실시하였고 그 결과 목표수질을 달성할 수 있는 배수구역별 부하량을 할당하였다.

The purpose of this study was to evaluate the effects of a computerized cognitive training(CCT) on cognitive, depression, life satisfaction and activity of daily living in older adults with mild dementia. The participants were 32 older adults diagnosed with mild dementia who reside in nursing hospital and were randomly divided into an 16 for an experimental group and 16 for a control group. A CCT was performed for a day/week for 8 weeks in an experimental group. The CoTras-G was used for CCT. The MMSE-K, SGDS-K, ELS and BI were administered to the experimental group and the control group in the same way in order to examine the effects of CCT. The difference of the effects between before and after a CCT conduction were identified by paired t-test. Moreover, the Mann-Whitney U-test was conducted to identify differences in variances between groups. Only participants in the experimental group reported significant improvements in cognitive function, depression, life satisfaction and activity of daily living when compared to those in the control group after CCT. There was a significant difference in cognitive function, depression, life satisfaction and activity of daily living between the experimental group and the control group after CCT. These findings suggest that the CCT can be used as effective cognitive training program to improve cognitive function, depression, life satisfaction and activity of daily living in older adults with mild dementia.

Survey research, data is commonly collected through a sample design with complex design features that allow the relative efficiency on the precision of an estimator to be measured using the concept of the design effect compared to simple random sampling as a reference design. This concept is most useful when the design effect can be expressed as a function of various design features. We propose a design effect formula suitable under a stratified multistage sampling by generalizing Gabler et al. (1999, 2006)'s approaches for multistage sampling. Its use can either guide improvement in the design efficiency when in design stage or enable the evaluation of the adopted design features afterwards.

This study examined the effect of valence for best reply on the conformity of general reply in online environment. A total of 194 participants participated in this study, each participant assigned randomly in three experimental groups(positive, negative, and control). Participants were asked to read online news article, best reply and general 6 replies, and then, to write their own opinions in the reply section. In addition, the level of self-expression and issue commitment were measured. The contents of reply participants written was categorized three valence(positive, negative, and neutral) by the four experimenters' judgment. The mean of inter-rater reliability was 84.9%. The results indicated that the level of self-expression and issue commitment were comparable across experimental conditions. However, the result of cross-table analysis showed that there is a significant difference in the valence of general reply across experimental conditions. Specifically, there were significant difference in the valence of general reply between positive and negative experimental group and positive and control group, but there is no significant difference between negative and control group.

A stochastic modeling approach as a mathematical method for workflow intelligence is widely used for analyzing and simulating workflow models in the literature. In particular, as a resource-centric modeling approach, this paper proposes a stochastic model to represent work-handover relationships between performers in a workflow-supported social network. Calculating probabilities for the work-handover relationships are determined by two types of probabilities. One is the work-transition probability between activities, and the other is the task assignment probability between activities and performers. In this paper, we describe formal definitions of stochastic workflow models and stochastic work-handover relationship models, as well. Then, we propose an algorithm for extracting a stochastic work-handover relationship model from a stochastic workflow model. As a consequence, the proposed model ought to be useful in performing resource-centric workflow simulations and model-log comparison analyses.

This sturdy proposed and tested whether the six core treatment processes of Acceptance and Commitment Therapy (ACT) reduce self-criticism and dichotomous thinking in Evaluative concerns perfectionists and even diminish depression and ultimately verify it. The sample consisted of 22 subjects who displayed high EC perfectionism and depression. The subjects were randomly assigned to ACT groups or control groups (n-11/each). The ACT program was administered in eight sessions. All participants completed scale about EC perfectionism, self-criticism, dichotomous thinking, depression and acceptance & action at the pre-test, post-test, and the six week follow-up. The results showed that evaluative concerns perfectionism, self-criticism, dichotomous thinking, and depression decreased more in the treatment group than in the control group, whereas acceptance & action increased in the former. Finally, the implications and limitations of this study, along with suggestions for future study were discussed.

This study looked into the effects of acceptance and commitment therapy(ACT) program on the premenstrual symptoms, attitudes toward menstruation and perceived stress, in females in their 20's suffering from premenstrual syndrome(PMS). Among the 263 students from 3~4 year universities, 21 were selected as participants. 7 were assigned to the acceptance and commitment therapy(ACT) group, 7 were assigned to the cognitive behavior therapy(CBT) group, and 7 were assigned to the control group. As a result, emotional factor from the premenstrual symptoms has significantly decreased more in the acceptance and commitment therapy(ACT) group, and the cognitive behavior therapy(CBT) group in comparison to the control group. In regards to attitudes toward menstruation, there were no statistical significance in the acceptance and commitment therapy(ACT) group, however there were positive changes, and the cognitive behavior therapy(CBT) group displayed significant change in the follow-up study. In perceived stress, acceptance and commitment therapy(ACT) group displayed more significant decrease than the control group and the cognitive behavior therapy(CBT) group, and that level remained unchanged until the follow-up study.
