The aim of this research is to attempt to extend previous work in this field by devising a set of intervention activities which could be used by teachers to help children to develop towards the commonly accepted scientific understanding of sound from constructivist strategies, and to compare the children's ideas about sound between pre- and post- Intervention. A set of structured activities was then provided which should allow children to explore sound phenomena. Full sets of data were collected from 43 children in total(n=11 for grade 1, n=15 for grade 3, n=17 for grade 5). These data related to everyday sound, string telephone, drum, funnel and rubber band activities were analysed by some categorical schemes. The major findings of this study are as follows: 1. There are significant changes in children's ideas over the interventions. These changes are most conspicuous in connection with sound production and sound transmission. The age group which show most distinctive changes are the grade 3 and grade 5. The most effective activities in promoting change of sound production are drum and rubber band. 2. Examining the individual changes of schematic chart show that a large number of children have developed their ideas in a way which can help them to develop scientific thinking.

Many psychiatrists insist that early parental loss is an etiologic factor for psychiatric disorders, but some investigators refute this hypothesis. The aim of this study was to investigate the relationship between parental loss in childhood and the development of psychiatric disorders, and to examine the above two controversial opinions. The author studied the frequency of parental loss, sex of the lost parent, reason of parental loss, and age at parental loss in 300 psychiatric patients and 300 controls who were age and sex matched. The results were as follows; 1. The psychoneurotics had significantly higher frequency of maternal and both parental loss compared with controls. But no significant difference was found between the psychotics and controls. 2. Psychiatric patients had higher frequency of early (before 18 years) parental loss than controls, but the difference was not significant except in the both parental loss group. In the early (before 18 years) parental loss group of psychiatric patients, the frequency of one parental (paternal or maternal) loss was significanty high in 0-5years compared with controls. 3. Frequency of maternal seperation was high in the psychiatric patients compared with controls.

The purpose of this study was to examine the influence of the achievement goal orientation of amateur marathoners on their participation satisfaction and exercise adherence in an effort to provide some information on those engaging in marathon as a sport for all and to expedite the development of sports for all. The subjects in this study were 300 amateur marathoners who were selected by convenience sampling from among the participants in nationwide marathon competitions that were respectively held in North Chungcheong Province and Incheon in 2014. After a survey was conducted, the answer sheets from 261 respondents were analyzed except 39 ones that were incomplete or included multiple replies. The instrument used in this study was questionnaire that consisted of five items, which were two about demographic characteristics of gender and age and three about the period, frequency and time of participation. As for achievement goal orientation, Kim Byeong-joon(2001)'s Sport Achievement Goal Orientation Questionnaire that was an adapted version of Duda & Nicholls(1992)'s Task and Ego-Orientation in Sport Questionnaire(TEOSQ) was modified to be suitable for marathon. Concerning participation satisfaction, Kim Young-jae(2004)'s Korean Leisure Satisfaction Scale(KLSS) that was based on Beard and Ragheb(1980)'s Leisure Satisfaction Scale(LSS) was modified to suit marathon. Regarding exercise adherence, Choi Seong-hoon(2005)'s Korean Exercise Adherence Scale for Sports for All and Leisure Sports was utilized. As for data analysis, a statistical package SPSS WIN 21.0 was employed to analyze the collected data. A frequency analysis was made to find out the demographic characteristics of the respondents, and t-test and one-way ANOVA were used to see whether there would be any differences in achievement goal orientation, participation satisfaction and exercise adherence according to their gender, age, period of participation, frequency of participation and time of participation. To determine the mutual influence of achievement goal orientation, participation satisfaction and exercise adherence, simple regression analysis and multiple regression analysis were made. The level of statistical significance was all set at .05. The findings of the study were as follows: First, concerning the influence of the achievement goal orientation of the amateur marathoners on participation satisfaction, task orientation had a significant impact on participation satisfaction. Second, regarding the impact of the achievement goal orientation of the amateur marathoners on exercise adherence, task orientation exerted a significant influence on exercise adherence.

금속 이온이 존재하는 조건에서 성장하는 식물이나 효모에서 발견되는 금속-결합 펩티드는 글루타티온으로부터 유도되며 (γglu-cys)_(n)X 구조를 갖고 있다. 이런 펩티드를 피토켈라틴, γ-글루타밀 펩티드, 또는 부류 III 메탈로티오네인 (class III metallothionein)이라고 한다. 여기에서는 피토켈라틴의 일차구조, 금속-티올 배위결합, 생합성 및 관련된 효소, 금속내성과 항상성 같은 기능에 대하여 논의한다. Metal-binding peptides derived from glutathione were found in yeasts and plant species in the presence of added metal ions. The structure of these peptides was established as (γGlu-Cys)_(n)X. They have been designated as phytochelatins, γ-glutamyl peptides, and class III metallothioneins. In this paper, we reviewed phytochelatins in respect of the primary structure, metal-thiol coordinated cluster, biosynthesis and related enzymes, and functions such as metal tolerance and homeostasis.

The purpose of format conversion is to convert a wide range of personal computer video formats into a target format. Circuits for the conversion have been developed by means of interpolation techniques, such as zero-order interpolation, bilinear interpolation, and bisigmoidal interpolation. This paper proposes a scan converter using cubic splines. The converter was modeled in VHDL on Max+PlusⅡ and implemented with an FPGA chip. The circuit gives much better conversion performance than a scan converter with zero-order or linear interpolation.

The prevalence of PPNG among pretreated gonorrhea cases isolated at the STD clinic of Choong-Ku Public Health Center in Seoul has been studied and reported annually since 1981. In 1991, 123 strains of N.gonorrhoeae were isolated, among which 58(47.1%) were PPNG. In 1992, 98 starains of N.gonorrhoeae were isolated, among which 51(52.0%) were PPNG. In all, 109(49.3%) strains were found to be PPNG among 221 strains isolated between 1991-1992. The prevalence of PPNG in Seoul showed increased tendency till 1989, thereafter, it has been stationary or slightly decreasing.

Geographic information system-based identification of suitable cultivation sites for wood-cultivated ginseng

Beon, Mu Sup,Park, Jun Ho,Kang, Hag Mo,Cho, Sung Jong,Kim, Hyun The Korean Society of Ginseng 2013 Journal of Ginseng Research Vol.37 No.4

Wood-cultivated ginseng, including roots in its dried form, is produced in forest land without using artificial facilities such as light barriers. To identify suitable sites for the propagation of wood-cultivated ginseng, factor combination technique (FCT) and linear combination technique (LCT) were used with geographic information system and the results were superimposed onto an actual wood-cultivated ginseng plantation. The LCT more extensively searched for suitable sites of cultivation than that by the FCT; further, the LCT probed wide areas considering the predominance of precipitous mountains in Korea. In addition, the LCT showed the much higher degree of overlap with the actual cultivation sites; therefore, the LCT more comprehensively reflects the cultivator's intention for site selection. On the other hand, the inclusion of additional factors for the selection of suitable cultivation sites and experts' opinions may enhance the effectiveness and accuracy of the LCT for site application.
