To determinate self-purification constants of pollutants loaded in the ecosystems, the self- purification process was formulated, and a measurement method of the self-purification constants was derived. $C=C_0e^{-st}$ When $C_0$ is the initial pollutant amounts loaded in a ecosystem, and C is the rest pollutant amounts after the time, t, the equation of the self-purification, s, is $s=\frac{P}{C}$ When in aquatic ecosystem, $C_0$ is the initial polluant amounts loaded in water body, and Cis the rest pollutation amounts after the time, t, the self-purification constant, s, is $s=(\frac{\ln C_0-\ln C}{t}$ Self-purification constants of pine and oak forests at kwangneung in kyonggido were 0.07 and 10 respectively, of BOD in gokneung stream in kyonggido was 0.51, and of glucose and phosphate in pools on the stone in mt.jiri were 0.49 and 15.19 respectively.

본 연구는 비영리단체에 기부를 하는 소비자들의 자선충동의 동기가 심리적 성과에 미치는 영향을 탐색적으로 살펴보았다. 이를 위해 본 연구는 자기결정성 이론에 근거한 비영리 단체에 대한 자선충동 동기가 소비자-비영리단체 간의 동일시를 매개변수로 하여 기부충성도에 영향을 미치는 요인임을 제시하였다. 본 연구는 기부자들이 비영리단체에 대한 심리적 측면에서의 자선충동 동기에 관한 연구가 전무한 실정에서 자선모금기관이 재원을 확보할 수 있는 효과적인 마케팅 전략을 구축하는데 기초자료를 제공하며 소비자들의 자선충동 동기에 대해 탐색하는 최초의 연구로서 중요한 의의를 가진다.

This paper presents the main method to analyze the dynamic characteristics of power transmission system using the multi-body dynamics, which is based on the concept of subsystem equation, subsystem assembling, and the self-determination technique for the system degree of freedom. We can model the mechanical components of power transmission system easily with the advantage of multi-body dynamics. Based on the theory, a dynamic simulation program was developed to analyze system performances, transient phenomena, and other dynamic problems. The driving performance of automatic transmission was simulated with using the multi-body dynamics and Newtonian method, and the validity of program was proved by comparing the two kinds of result.

본 연구의 목적은 남녀 대학생의 자기결정성, 우울, 자아존중감, 충동성, 스마트폰 과의존간의 관계를 탐색함으로써 이들 요인이 대학생의 스마트폰 과의존에 미치는 영향을 규명하기 위함이다. 2개 대학교에 재학중인 남녀 대학생 263명을 대상으로 자가보고형 설문조사를 실시하였다. 연구결과 남학생의 스마트폰 과의존에 영향을 미치는 요인은 스마트폰의 중요성에 대한 인식(${\beta}=.411$, p<.001), 충동성(${\beta}=.204$, p=.007)과 우울(${\beta}=.200$, p=.040)인 것으로 나타났다. 여학생의 스마트폰과의존에 영향을 미치는 요인은 스마트폰의 중요성에 대한 인식(${\beta}=.630$, p<.001)과 충동성(${\beta}=.185$, p=.010) 이었다. 본 연구결과를 바탕으로 남녀 대학생의 충동성 조절 및 스마트폰에 대한 왜곡된 인식 변화를 통해서 남녀 대학생의 스마트폰 과의존을 예방하기 위한 맞춤형 프로그램 개발이 필요하다.

Purpose: This study was done to discover the contents needed for a sexual education program in the lower grades (the first to the third grade) by primary school teachers and to discover difficulties in confronting sexual education. Method: This was a descriptive study of 198 teachers for lower grade students in 15 primary schools. A questionnaire on sexual education was distributed and collected by mail. Result: The contents for sexual education that teachers felt were highly needed are as follows: sanitation of genitals, sexual violence, pregnancy & childbirth, family, selfassertion, and sexual self-determination. Teachers think prevention of sexual violence is the main reason for sexual education. Teachers indicated that sexual education considering the developmental stage was difficult. Conclusion: Development of a sexual education curriculum for lower grade primary school students is necessary for increasing the problem-solving ability of students focused on sexual violence, self-assertion and sexual self-determination, in addition to providing simple information.

Purpose: The purpose of this study was to develop and test a hypothetical model which explains health behavior adherence in elderly people with prehypertension. The model was based on self-determination theory (SDT). Methods: Data were collected from June 21 to July 15, 2010, using self-report questionnaires. The participants were 140 elders with prehypertension who lived in D Metropolitan City. Collected data were analyzed using PASW 18.0 for descriptive statistics and correlation analysis and AMOS 5.0 for covariance structure analysis. Results: It appeared that the overall fit index was good with a ${\chi}^2$ score of 13.23 (p<0.05), GFI of 0.97, AGFI of 0.79 and RMR of 0.28 in the modified model. The results revealed that significant main effects of both health provider's autonomy support and autonomous motivations were found on the measure of health behavior adherence. These factors explained 72% of variance in the participants, health behavior adherence. Conclusion: The overall findings may provide useful assistance in developing effective motivation-enhanced programs for health behavior adherence.

This paper proposes an autonomous fault determination, fault zone isolation and fault restoration strategy based on the ethernet communication as a new attempt to solve the problem the of the existing central control method. In proposed method, The FRTU(Feeder Remote Terminal Unit)s on the feeder determines autonomously where the faulted zone is by exchanging the voltage and current information with neighbor FRTUs based on the network communication, and then separates the faulted zone in an nil-voltage status to make the protective device to reclose successively. In particular, the minimization of outage time and relational load balancing is archived by each interconnection switch which determines autonomously the load zone to be allocated among those zones after the sound outage zones was separated individually. Finally, to show effectiveness of the proposed fault restoration strategy, the several fault cases are simulated for the test distribution system, and the load balancing index of the proposed solution is compared with all of feasible solutions.

Purpose: This study aimed to develop a motivational interviewing pulmonary rehabilitation program based on self-determination theory to maintain pulmonary rehabilitation-related health behaviors in patients with chronic obstructive pulmonary disease. The program was developed by reviewing the literature on pulmonary rehabilitation guidelines, drawing on the self-determinism theory to establish its contents, recruiting experts to test its validity, and conducting a preliminary survey. Methods: A quasi-experimental design was used to confirm the effect of the program. The participants were outpatients diagnosed with chronic obstructive pulmonary disease at three general hospitals in Busan. There were 33 subjects: 15 in the experimental group and 18 in the control group. The experimental group performed a motivational interviewing pulmonary rehabilitation program which comprised 11 sessions delivered over 10 weeks. The outcomes were measured using basic psychological needs, dyspnea, 6-minute walking distance, and functional status. Intervention effects were analyzed using repeated-measures ANOVA. Results: The analysis revealed significant differences between the experimental and control groups in competence among the subdomains of basic psychological needs, dyspnea during exercise, and functional status. Conclusion: The developed program affects physical conditions and can be applied as an effective clinical nursing intervention to continuously improve the pulmonary rehabilitation behavior of patients with chronic obstructive pulmonary disease.

In a world where opportunities and chances are common, the phenomenon referred to as "generation maybe" describes people in their 20s and early 30s who are usually being indecisive. With the increase in breadth of information and choices, the number of people who are hesitant in deciding whether to purchase increases at a fast pace, as does the number of products and services targeting this group. In order to enhance our understanding of the phenomenon of consumer hesitation, this study explores contextual factors and consumer characteristics that affect consumer hesitation in the purchase decision-making process. Specifically, this study examines whether seven contextual factors, self-determination tendencies, and five decision-making styles influence consumer hesitation in the product decision making process. An online survey was administered to test our research questions. A total of 309 Korean consumers (female=48.9%) aged from 20 to 35 were surveyed. A regression analysis revealed that four contextual factors (product involvement, need for information on alternatives, relative price, and uncertain need), two sub-dimensions of self-determination (perceived competence and relatedness), and two decision-making styles (price seeking and advice seeking) have noticeable influences on consumer hesitation. We also found that the degree of consumer hesitation positively influences consumer post-purchase satisfaction. The study concludes with discussions and practical implications.
