The primary purpose of this study was to develop performance evaluation indices for measuring the results of the work and performance of the career exploration support centers. For the study, First, to describe the current status of the management system across the 228 centers, examine the staff's perceptions of the current evaluation method and system of each center, and analyze the needs of measuring indices of each center for its performance evaluation, a cross-sectional survey method was employed. Second, relevant literature was reviewed. Next, measurement indices were developed employing the Delphi method with a panel of 15 experts in developing instruments of accomplishment. Based upon the conclusion of this study, The measurement indices developed in this study focuses on the core measurement indices. These indices include a checkbox of necessary and unnecessary in each item so that each local department of education or each center can select indicating items (indices) according to its own needs. The newly developed measurement indices consists of four domains to assess: (1) Institutional competencies-goals, budget, system, and resources, (2) Practitional competences-qualities of programs, administration of experiential career program providers, promotion of centers and programs, management of human resources such as instructors or guides, and establishment of community-center cooperative networking system, (3) Accomplishments-finding new experiential career program providers, the number of participants such as schools and students, reciprocal system, and the degree of participants' satisfaction with the center and programs, and (4) specialized indicators-extra scores for center-based specialized programs.

The purpose of this paper was to classify areas demanding to be transformed to green spaces and evaluate their grades for urban park and green networks. The results of this study are summarized below; 1. The results of the classified green spaces in the research areas fall into three types including children parks, neighborhood parks, and public green spaces. The three types of green spaces were analysed with recreational indexes. The zones disturbing the green-networks were sorted out. These zones should be changed into a supplementary green spaces for improving the recreational functions in the city. 2. For urban park and green networks, distances between the parks and size of the parks were adopted as indices. Based on the index of distances between the parks, disturbing zones were evaluated with 3 grades. The first grade includes primary industrial complexes and housing complexes. The second grade was observed mostly in industrial complex areas. The third grade includes housing complexes. Based on the indexes of size of parks, disturbing zones were evaluated with 2 grades. In the case of grade I, it appeared in housing complex. In the case of grade II, it appeared in industrial complex. 3. Then, we prioritized the disturbing zones with severity in order to make supplementary green spaces. Through the process, the zones of the grade I for two each recreational index were evaluated to two grades. The analysis results of evaluated zones were that grade II appeared over industrial and housing complexes widely. Grade I appeared over housing complexes. 4. It is necessary that the grade of disturbing zones should be considered as an order to make green spaces to supplement a green-network. For this, we formed a basic frame of a green-networks in Dalsu-Gu and placed the disturbing zones on the basic frame of a green-network. Consequently, The results were that the green-networks in Dalsu-Gu was composed on four green-network axes and its shape mirrored a cruciform (+) of northwest$\leftrightarrow$southeast direction and southwest$\leftrightarrow$northeast direction.

Stress is experienced when a person tries to maintain stability in the face of life change but is not able to meet the adaptive demands of change. This can be especially true for the parents who has a cerebral palsy childs who needs long term rare, where parents, are the primary source of care and responsibility. Successful coping leads to maintenance of the parents role and this has an effect on the health status of the child. This descriptive study was attempted to identify stress factors, levels and helpful coping patterns for parents who must take care of cerebral palsy children. Data were collected from 43 subjects who were parents of children diagnosed with cerebral palsy The informations gathered from March 25, 1994 to April 14, 1994 by means of structured questionnaires were analyzed. Two instruments were used to collect the data 1) Lee's stress questionnaire consisted of 33 stress factors and measured by four point Likert scale. 2) Modified Chronic Health Inventory for parents: The modified CHIP included 43 items of coping methods with four point Likert scale. The results of this study were as follows: 1) Stress items could have a maximum score of three points, for a total possible score of 132 points. The mean score for the total was 92.02 points. The item mean score was 2.85 points showing that the parents were experiencing moderate to much stress. 2) The items with the highest stress items were 16 items. The stress items with the lowest mean scores were 10 items. 3) Of the stress categories: The highest stress category was related to changes in the illness status of the child and difficulty in taking rare of the child. The second stressful category was related to the prognosis of the child's condition. The least stress was noticed to social-personal relationships and the responsibility of the care givers. 4) Items measuring coping in the parents had a maximum score of three points each with a total possible roping score of 172 points. The mean score for the total was 103,9 paints. The item mean score was 2.42 points indicating that there were responses of little helpful to moderately helpful on each coping pattern. 5) The most helpful coping items were 7 items. The least helpful coping items were 2 items. 6) Effectiveness of the coping for each patterns was examined : Understanding the illness condition from communication with parents of children with the same condition and consultation with the medical team was the most helpful coping pattern. Family's coorperation and integration and optimism were a moderately helpful coping pattern. Social support psychological stability and self esteem were the least helpful toping pattern. In conclusion, the highest stress for parents of children with cerebropalsy was found to be very stressful changes in the illness of the child and to taking care of a child who is suffering. The parents were helped by the coping methods using understanding of the illness condition through consultation with the medical learn and communication with parents in the same situation. Based on the knowledge, care could develop intervention strategies appropriate for them, help them to develop their effective coping patterns, and give support them in the process of coping with their stress.

Background and Purpose : Hypertension is one of the modifiable risk factors for stroke. Lowering blood pressure is a primary or secondary preventative measure for stroke. This study aims to assess the efficacy of Chunghyul-dan(Qingxue-dan) in stage 1 hypertensive patients who have suffered a stroke by 24 hour ambulatory blood pressure monitoring(24ABPM). Subjects& Methods : We enrolled 40 hospitalized stroke patients with stage 1 hypertension and divided them into 2 groups by stratified randomization; group A took 1200mg of Chunghyul-dan(Qingxue-dan) at 8:00 a.m. for two weeks without changing herbal medicine, and group B was the control group. 28 patients were included in the final analysis(15 in group A. 13 in group B). Blood pressure is monitored from 8:00 am to 7:30 am every 30 minutes for 24 hours. Blood pressure was monitored two times at baseline and again two weeks later. We used 3 parameters for evaluating the efficacy of Chunghyul-dan(Qingxue-dan); The first parameter is change from baseline to two weeks later in blood pressure and pulse rate. The second parameter is the trough/peak ratio(TPR) and smoothness index(SI). The third parameter is antihypertensive rate by antihypertensive efficacy guideline. Results : There is no significant difference in the baseline assessment hetween the two groups. Systolic blood pressure $(141.37{\pm}8.96\;mmHg\;vs\;132.28{\pm}9.46\;mmHg)$ decreased after two weeks of 1200mg(P=0.03) intake of Chunghyul-dan(Qingxue-dan). Systolic TPR and SI was 0.87 and 1.04 in group A. Antihypertensive rate was higher in group A. Conclusion: These results suggest that 1200mg doses of Clunghyul-dan(Qingxue-dan) is an effective antihypertensive agent on stage 1 hypertension patients who have suffered a stroke.

The random utility theory and the multinomial logit model (including a more recent variant--the mixed multinomial logit) derived from it have constituted a back bone for theoretical and empirical analyses of various travel demand features including mode choice. In their empirical applications, however, it is customary to specify random utilities which are linear in modal attributes such as time and cost, and in socio-economic variables. The linearity helps easy derivation of important information such as value of travel time savings by calculating marginal rate of substitution between time and cost. In this paper the author focuses on the very linearity of the random utilities. Taking into account the fact that the mode chooser is also labour supplier, commodity consumer as well as leisure-seeker, the author sets up a maximization model of the traveller, which encompasses various economic activities of the traveller. The author derive from the model the indifference curve defined on the space of modal attributes, time and cost and investigate under what conditions the random utility of the traveller becomes linear. It turns out that there exist the conditions under which the random utility is really linear in modal attributes, but the property does not hold when the traveller has a corner solution on the space of modal attributes, or when the primary utility function of the traveller is directly affected by labour provided and/or the travel time itself. As a corollary of the analysis, a random utility is suggested, approximated up to the second order of the variables involved for empirical studies of the field.

The purpose of this study is to analyze elementary school teachers' perception on application of STEAM education. For this study, a survey was administered to 80 primary teachers. The result showed as follows: First, even though, elementary school teachers have known about the meaning and aims of the STEAM education in detail, they often took a neutral attitude toward the actual teaching method. In addition, they take a negative attitude toward having the gathering. Second, only a few elementary school teachers prepared and used the teaching materials related to the STEAM education in class and teach students the concept based on the STEAM education. Only a few elementary school teachers said that they used the developed modules. However, the demand, developing the modules, was extremely high. This result means that the easy and available modules should be developed to establish the STEAM education. Third, only a few elementary school teachers applied the subject, activity, and estimation related to the STEAM education in actual class. Forth, even though, after applying, there much be the positive affects, most elementary school teachers could not recognize the positive affects. At the same time, elementary school teachers suggested the curriculum should be reorganized for students to connect between the results of the STEAM education and the contents of the textbook, and the easy and available program should be developed and spread, also. The attitude of elementary school teachers toward the application of the STEAM education was normally negative. Therefore, it is needed to include more STEAM related contents in the science textbooks and to develop various STEAM education materials and circulate them as well as to establish adequate teaching and assessment methods for STEAM education.

In this study, we analyzed the written and drawn explanations of thirty elementary school pre-service teachers in order to examine their perception on the seasonal length of day and night. The main findings are as follows: First, pre-service teachers used the most common term in the description of the texts, such as meridian altitude, axis of rotation, and revolution, and there were more misconceptions in the drawn explanation than in the written explanation. Second, by analyzing the pre-service teachers' perceptions by combining written and drawn explanations, it is possible to detect scientific errors that the distance between the Earth and the Sun is closer when the axis of rotation is tilted in relation to the revolution and seasonal changes due to changes in the orbital radius of the Earth. In addition, there have been types of explanations such as seasonally changing meridian altitudes related to the rotation of the Earth but no change in the location of the Sun. Based on the results of the analysis, we discussed the lack of experience in constructing an explanatory system of specific phenomena using scientific knowledge, lack of observational experiences about natural phenomena, and lack of exposure to other explanatory systems that cause cognitive conflicts. We hope that it will be concrete and practical help to improve the understanding of pre-service teachers in the science domain of primary teacher training program.

This study is to objectively deduce components of a public library culture and define a library culture. Thus, the study gathers the opinions and the experiences of the expertise in this specific area of a library culture. Furthermore, the study takes gathered informations and dates into consideration, to derive a measurement of final components, delphi technique. Through usage of Delphi technique, it allowed selected final components to operate a comparative analysis of the elements, which then it helps to measure each element's critical importance, identify priorities of each element by using a hierarchical decision making method. The major conclusions of this study are as follows. First, the study used a two-step delphi survey which was conducted on a panel of experts (Faculty of Library and Information Science (LIS) and the librarians), deduced the components of a library culture. In the primary survey, the study found 29 components (material culture 6, non-material culture 23). In the secondary survey, it deduced 21 components (material culture 3, non-material culture 18). Second, through comparative analysis, the prioritization of the public library culture components presented in following orders, , , and . The Most weighted values of each components were, of 'data usage and its method.'; of 'core values of librarianship'; of 'library ethical consciousness.' appeared as such.

Amine-type PP-g-VBC-EDA adsorbent, which possesses anionic exchangeable function, was prepared through photoinduced graft polymerization of vinylbenzyl chloride (VBC) onto polypropylene non-woven fabric and subsequent amination reaction using ethylenediamine (EDA). Adsorption characteristics of anionic nutrients on the PP-g-VBC-EDA adsorbent have been studied by batch adsorption experiments. The equilibrium data well fitted the Langmuir isotherm model, and the maximum monolayer sorption capacity was found to be 59.9 mg/g for $NO_3-N$ and 111.4 mg/g for $PO_4-P$. The adsorption energies were higher than 8 kJ/mol indicating anion-exchange process as the primary adsorption mechanism. The pseudo-second order kinetic model described well the kinetic data and resulted in the activation energy of 9.8-36.7 kJ/mol suggesting that the overall rates of $NO_3-N$ and $PO_4-P$ adsorption are controlled by the chemical process. Thermodynamic parameters such as ${\Delta}G^o$, ${\Delta}H^o$ and ${\Delta}S^o$ indicated that the adsorption nature of PP-g-VBC-EDA for anionic nutrients is spontaneous and exothermic. The PP-g-VBC-EDA could be regenerated by washing with 0.1 N HCl.

Tibetans who live in the Tibetan highlands, the Roof of the World, have their own unique lifestyle wherein they conform to its long history, natural environment, and their own form of clothing culture. In their costumes, the use of colors, patterns and designs express religious meaning and represent the hopes and heart of life, which respects nature. This study aims to analyze the colors used in Tibetan costumes and examine the meaning of these colors. In addition, this study intends to understand the specificity of Tibetan culture through a consideration of the symbolism of the colors of ethnic costumes. By examining the literature and conducting case studies, colors of Tibetan costumes were analyzed through the I.R.I HUE-TONE system. We analyzed 96 photographs of the costumes photographed during the Tibet ceremony costume, photographs seen at the Qinghai Tibet Culture Museum and photographs from the Internet museum. The results revealed the following: First, the most important element of the costumes is connected to the five colors of JangOsaek, which gives meaning to each color. Red, navy blue, yellow, white and green symbolize fire, the sky, earth, clouds or snow, and grasslands, respectively. Second, Tibetan costumes are characterized by bold color contrasts such as red and green, black and white, red and yellow, and yellow and purple to achieve an intense harmony of colors. Third, these fancy costumes express the unique aesthetics of the Tibetan people. The primary colors follow general emotions, but they can also include their own emotion.
