This study was conducted to know whether Gamiyookmijihwangtang(GY) which is Yookmijihwang added with Liriopis tuber, Anemarrhenae rhizoma and Phellodendri cortex can remedy the overt diabetes in diabetes-prone BB(BBDP) rats. The rats were given GY through the mother from the fetal stage until birth. After birth they received GY through breast feeding until 20 days old. From 21 days old which is the beginning of the weaning period 60 BB rats(30 males and 30 females) were divided into 2 experimental groups(BBDP and BBDP-GY) and placed individually in metabolic cages. BBDP was the control group which didn't receive any GY and BBDP-GY received 16 mL/㎏ B.W./day of GY until 120 days old. The antidiabetic effects of GY were characterized by the clinical features such as polyurea, polydipsia, hyperglycaemia and the rapid loss of body weight. Body weight, water consumption, urine volume and blood glucose level showed no signs of impending diabetes but after onset there were big changes in those parameters. The onset of diabetes was delayed and the incidence of diabetes was also much decreased with GY but after onset there were no beneficial effects from it.

The main purpose of this research is to provide scientific informations about standard wage and performance tariffs in forest management with special reference to working time for thinning. To identify relationships between net working time and tree characteristics, three geographically different sample plots were established at Yangsan, Bongpyung and Jinan and 460 oaks, 372 Japanese larches, 232 red pine and 240 pitch pine mere selected at each sample plots. The results of statistical analysis using multiple regression are as follows ; 1. Five independent variables of breast height diameter(DBH), mid-diameter(MD) large end diameter(LD), log-length(L), No. of branches(NOB) were stable independent of worker and tree species. 2. Comparing correlation coefficient of five independent variables, the best predictive variables, breast height diameter and No. of branches, were selected. Breast height diameter and No. of branches were identified as the most important independent variables in terms of effect on the dependent variable of the working time. 3. Comparing coefficient of determination (Rp) and residual mean square (MSEp), the best Linear regression equation for each tree species was selected as follower : $WT=a+b1{\times}NOB+b2{\times}DBF$ 4. Proportion of hang-up time to total working time in thinning were 66% in oak stand, 74%, in Japanese larch stand, 55%, in red pine stand and 52% in pitch pine stand, respectively. 5. Based on the best regression equation, a table of working time was made by strata of number of branches and breast height diameter. 6. Total working time using the best regression equation in Table 5 can be predicted in terms of felling time, limbing time, hang-up time, i.e., total working time increases by 11 to 13 seconds with every 1 centimeter increase in breast height diameter from 7 to 16 centimeter.

This study aimed to investigate the mediating effects of spiritual well-being and ego resilience in the association between parent-child relationships and cultural adaption among children from multi-cultural families. For this purpose, surveys were administered to 4th to 6th graders in 200 elementary schools (150 multi-culturally focused and 50 in preparation for multi-cultural education) located in seven provinces in Korea. For the current study, we analyzed data collected from 706 children in 119 schools by utilizing structural equation modeling. To verify the mediating effects and its significance, a Sobel test was conducted. The results showed that parent-child relationships within the multi-cultural families was positively and significantly associated with spiritual well-being and ego-resilience in children, but not with children's cultural adaptation. Also, the results of the Sobel test showed significant mediating effects of spiritual well-being and ego-resilience in children in the association between parent-child relationships and children's cultural adaptation. Based on these results, policy and practice implications for children from multi-cultural families are suggested.

Several criticisms notwithstanding, the major political parties in South Korea seem to have developed relatively coherent 'collective identities' with regard to the unification question between South and North Korea. A comparative analysis in this paper reveals a certain pattern of convergence and divergence in unification policies among major parties. First, diachronically, the two major political parties in the history of South Korea, which I call for simplicity "conservative parties" and "democratic parties" respectively, have converged into allelosubjective attitudes towards North Korea since President Park Chung-hee's proclamation of peaceful unification plan in 1970. The governments of conservative parties since then promoted allelosubjective relations between South and North Korea, which the governments of democratic parties succeeded and developed into a partial integration policy. Though the succeeding governments of conservative parties of Lee Myung-bak and Park Geun-hye seem to have stepped back from the allelosubjective attitudes, seemingly they have not yet withdrawn to the monosubjective stance before 1970. Next, synchronically, an analysis of the platforms of major parties and their campaign promises in the 20th general election in 2016 reveals converging and diverging points in their unification policies. All the major parties show relatively allelosubjective attitudes towards North Korea, with significant differences. "Saenuri Party," the current conservative party, maintains quite bit of monosubjective attitudes towards North Korea and requires unilateral changes of North Korea in the process of unification. "Justice Party," the minor progressive party, is the most allelosubjective in that it presupposes the co-existence and mutual survival of the two Koreas in unification. In between lie "The Minjoo Party of Korea" and "The People's Party", the two parties separated in the democratic party bloc.

Traditionally, travel demand forecasts have been conducted based on the data collected by a survey of individual travel behavior, and their limitations such as the accuracy of travel demand forecasts have been also raised. In recent, advancements in information and communication technologies are enabling new datasets in travel demand forecasting research. Such datasets include data from global positioning system (GPS) devices, data from mobile phone signalling, and data from call detail record (CDR), and they are used for reducing the errors in travel demand forecasts. Based on these background, the objective of this study is to assess the feasibility of CDR as a base data for travel demand forecasts. To perform this objective, CDR data collected for Daegu Metropolitan area for four days in April including weekdays and weekend days, 2017, were used. Based on these data, we analyzed the correlation between CDR and travel demand by travel survey data. The result showed that there exists the correlation and the correlation tends to be higher in discretionary trips such as non-home based business, non-home based shopping, and non-home based other trips.

The management standard on soil conditions in 'Fuji' apple to produce high quality fruit were not yet made. Therefore, this study was carried out to investigate the optimum soil environmental conditions of ten contents on production of high quality fruit in 'Fuji' apple. The soil and fruit characteristics were analyzed at total 60 orchards in major apple producing areas such as Chungju, Moonkyeung, yeongju, andong, yeosan and yeongcheon (10 orchards an area). The soil environmental factors affected fruit weight was highest relative contribution in saturated hydraulic conductivity of 36.5%. The bulk density and soil pH were low as relative contribution. The fruit weight was influenced by soil physical properties more than soil chemical properties. The soil environmental factors affected sugar content were hydraulic conductivity of 28.3% and organic matter content of 18.2%. The cultivation layer depth and soil pH were low as relative contribution. The fruit coloring was highest relative contribution in saturated hydraulic conductivity 55.9%. while soil pH, cation and soil texture were low. Fruit coloring was high influenced over 70% by soil physical properties. Finally, relative contribution on fruit quality related with sugar content, fruit weight, and coloring were high influenced by saturated hydraulic conductivity of 21.% and organic matter content of 18.7% but bulk density and cultivation layer depth were low relative contribution. The fruit growth and saturated hydraulic conductivity in 'Fuji' apple were very closely related. Therefore, orchard soil management to produce high quality fruit was very importance drainage management and organic matter application. We concluded that scientific soil management is possible by qualifiable of soil management factors.

This study tries to compare dose distribution between arc radiation therapy and Tomotherapy, which are main radiation therapy modalities. The subjects of this study are lung cancer patients. For planning target volume (PTV), a dose of 60.0 Gy was set as a basis. The PTVmean of Arc was 61.04 Gy, and that of Tomotherapy was 58.50 Gy. The total lung capacities of Arc and Tomotherapy were 3.0 Gy and 4.24 Gy, respectively. The mean heart doses of Arc and Tomotherapy were 0.13 and 0.34, respectively; the mean trachea dose of Arc and Tomotherapy were 1.35 and 2.58, respectively; the mean esophagus dose of Arc and Tomotherapy were 0.41 and 0.86, respectively; the mean spinal cord dose of Arc and Tomotherapy were 3.65 and 4.68, respectively. With regard to the appropriateness of therapeutic effect in DHV, both modalities seemed appropriate. Tomotherapy protected normal tissues better than Arc radiation therapy. In Tomotherapy, patients need to have treatment long in a limited space. If such a point is overcome, Tomotherapy is better. Otherwise, Arc radiation therapy can be applied. This study was conducted with treatment planning images. Therefore, the results of this study are different from actual treatment results. If more research is conducted to overcome the limitation, the effects of radiation therapy are expected to increase further.

Although planning techniques linking parks, green areas, and waterways have become common, there are frequent disruptions in the operation and management of landscape-use artificial channels (LuAC). Therefore, this study examined a design to promote the sustainable management and operation of a LuAC using rainwater for the streamlets of the Jeonju-Wanju Innovative City. In order to accomplish the purpose of this study, scenarios were set up by dividing the design into waterhead and waterway portions. First, the scenario regarding the waterhead was analyzed to calculate the water supply and storage required for the waterway and waterhead. The analysis showed that the waterway requires a water supply of 676.8 tons/months, 3,018 tons to 5,512 tons of storage space, and a water depth of 0.75 m to 1.37 m considering the ecological and landscape aspects. The second scenario is to select an effective system of facilities for the operation and management of the LuAC. To accomplish this, a single-circulation system (SCS), which transports water to a highland location was compared to a multi-circulation system (MCS), which supplied water separately to each water space and operated independently. The results showed that the MCS, which was operated independently by small power units, was more effective owing to the vast difference in water supply operation times.

In that all aspects of education can be compared from an international perspective, Comparative Education can share research subjects with most of the subdisciplinary study of Education. Especially Educational Finance and Economics, which is an important part of institutions and policies of education, has been one of the important areas in Comparative Education studies. In this regard, this paper summed up the relationship between Comparative Education and Educational Finance and Economics. Not only for the development of Educational Finance and Economics itself, but also in point of view of Comparative Education, it is as follows to discuss several tasks for Educational Finance and Economics to develop from now on. First, it is necessary to diversify the methods and approaches to Educational Finance and Economics. Comparative Educational studies or exploration on Educational Finance and Economics should require additional analysis from a variety of perspectives. Second, more efforts should be made to establish an independent theoretical framework for Educational Finance and Economics. Comparative Education may also be interested in international comparisons of these theoretical orientations or directions of Educational Finance and Economics. Third, we have to secure the identity of the Korean Educational Finance and Economics. Various comparative educational studies on Educational Finance and Economics of Education from an international perspective should be attempted on the basis of indigenous and independent Educational finance and Economics. Educational Finance and Economics are areas in which comparative educational analysis is needed more than any other study field of Education. We look forward to more active research on Educational Finance and Economics in the future from a comparative educational standpoint.
