Nowadays a sense of community based on our community further weakens due to globalization, industrialization, the development of transportation and communication, etc and the community as cultural and psychological units is focused on. In other words, the concept that emphasizes the aspect of 'we' sharing the unique value and goal of community is used. In this current situation, school as an important community organization has been in the spotlight. In particular, college compared with other communities has a special influence on the community. Therefore it is regarded as an important community organization and its importance as part of our efforts to decrease the college students wastage rates continues to grow. The study about school as an important community organization has been conducted actively. However the people in most studies are elementary, middle, and high school students, so there are limitations to what these study findings apply to college. Therefore, this study conducted factor analysis of college sense of community for local college students, categorized it, analyzed the factors having influence on each factor and then looked for suggestions of ways to strengthen college sense of community. According to study, sense of community is categorized into three factors such as 'sense of belonging', 'sense of solidarity', and 'sense of emotional closeness'. After analyzing the factors influencing types of sense of community, factors relevant to them are grades, intimate friends, subjective well-being, community volunteer work, college service satisfaction, and so on.

The rural extension in Korea faces transient period since Green Revolution. The urban-centered rapid industrialization policies have initiated the changes in rural and agricultural sector. Nowadays, the World Trade Organization (WTO), newly established by the agreement of the Uruguay Round (UR), is accelerating the changes in rural areas. The rural structural adjustment program established in 1990, in order to cope with the internal and external changes encompassing rural Korea. The rural structure adjustment program is a political responses to reduce the development gaps among industries and regions within the country and to reinforce the price competitiveness of agricultural products toward trade liberalization. This study aims to apply the contents and principles of the rural structural adjustment program for the extension education. It argues that the rural extension should play a pivotal role to gather, process, and deliver the information related to the rural structural adjustment initiating rapid rural social changes. It suggests that the rural extension services should deal with the development of industries through introducing business management techniques and linking relevant laborers, and the education and employment guidance of potential employees as well as the technological assistance on farm management to farmers.

Populus. caspica L. is an Iranian indigenous poplar species which naturally distributed in the northern part of country. Unfortunately, overuse has removed many of the stems of better form, so that natural stands now usually appear small and crook. Therefore genetic variation for selection of new superior clone of this species is needed. Conventional hybridization system is currently used to induce genetic variation in poplar species but incompatibility barriers have been observed between them. In vitro ovule embryo culture was used to overcome incompatibility obstacle for interspecific hybridization between Populus caspica L. with Populus deltoids L.62/75. Female flowers of Populus caspica L. have artificially been pollinated with pollen grain of P. deltoides 62/75 in one direction using twig and pot crossing system. Ovaries at different ages (7, 14 and 21 days after pollination) were disinfected through 70% ethanol for 1 minute, 5% of sodium-hypochlorite solution for fifteen min followed by three time rising with sterile distil-water. Isolated ovaries were then transferred to MS hormone free medium containing 30 and 60 g/L sucrose for embryo development and germination. Collected data have been analyzed by two factorial experimental designs. The results indicated that there were significant differences between age of embryos for development and germination at ${\alpha}=0.01%$. Highest embryo germination (45%) was observed from 21 days old ovaries. No significant differences were observed between MS culture media containing 30 and 60 g/L for percentages of ovary-embryo germination and number of germinated embryo per ovary at ${\alpha}=0.05%$. Fourteen percentage of embryo germination obtained in MS medium supplemented with 60 g/L sucrose, while only 35% of isolated ovaries were able to germinate in MS containing 30 g/L sucrose. Induced plantlets in 4 cm height were transferred into pots containing soilless (1:1:1 peat, per lit and vermiculite) medium for acclimatization. After successful acclimatization, plants were delivered to nursery.

Objectives: Nowadays cancer treatment is an important challenge in the medical world that needs better therapies. Many active secretions produced by insects such as honey bees used to discover new anticancer drugs. Bee venom (BV) has a potent anti inflammatory, anti cancer and tumor effects. The aim of present study is evaluation of anticancer effects induced by Apis mellifera venom (AmV) on cell Lines. Methods: AmV was selected for study on cancer cell lines. Total protein, molecular weight and LD50 of crude venom were determined. Then, cells were grown in Dulbecco's Modified Eagle medium supplemented with 10% fetal bovine serum and 1% antibiotics. The A549, HeLa and MDA-MB-231 cell Lines were exposed by different concentration of AmV. The morphology of cells was determined and cell viability was studed by MTT assay. Evaluation of cell death was determined by and DNA fragmentation. Results: The results from MTT assay showed that 3.125 ㎍/mL of A549, 12.5 for HeLa and 6.25 ㎍/mL of MDA-MB-231 killed 50% of cells (p < 0.05). Morphological analysis and the results from hoescht staining and DNA fragmentation indicated that cell death induced by AmV was significantly apoptosis. Conclusion: The data showed that using lower dosage of AmV during treatment period cause inhibition of proliferation in time and dose dependant manner. Findings indicated that some ingredients of AmV have anticancer effects and with further investigation it can be used in production of anticancer drugs.

This study was conducted to evaluate the effects of co-dried fish protein hydrolysate (CFPH) on broilers performance, intestinal microbiology, and cellular immune responses. Five hundred one-day-old (Ross 308) male broilers were allocated to four treatments with five replicates of 25 birds in a completely randomized design. The experimental treatments included four levels of CFPH (0% as the control, 2.5%, 5%, and 7.5%) in the isonitrogenous and isocaloric diets. During the experiment, body weight (BW) and feed intake (FI) were periodically recorded in addition to calculating average daily gain (ADG), feed conversion ratio (FCR), liveability index, and European broiler index (EBI). In addition, cellular immune responses were evaluated at 30 days of age. On day 42, ileal contents were obtained to examine the microbial population. Based on the findings, Dietary supplementation of 5 and 7.5% CFPH increased the percentage of the thigh while decreasing the relative weight of the gizzard compared to the control group. The highest relative length of jejunum was observed in birds receiving 2.5 and 5% CFPH, and its highest relative weight belonged to birds fed with 5% CFPH. The number of coliforms, enterobacters, and total gram-negative bacteria in the intestines of birds receiving CFPH was less than that of the control group. In general, the application of CFPH in broiler nutrition can decrease the level of soybean meal in diet and it can be considered as a new protein supplement in poultry production. It is suggested to study the incorporation of this new supplement in other livestock's diets.

This article indicates that the perceptions on the quality of agro-food are socially constructed. Farmers who were producing red pepper in Eumsung county had somewhat different perceptions on the quality of red pepper according to their own marketing channels. Farmers who were selling their red pepper to consumers by direct marketing tend to think the quality attributes more important as follows; information on producers, ingredients, taste and smell, amount of pesticides input, cleaning the harvested red pepper, quality certification by public authority, and brands. Consumers tend to think safety and production area more important, while farmers tend to think the quality attributes as follows; taste, color, variety, soil environment, and largeness. Based on these research findings, we can give some recommendations as follows; 1) the agricultural extension organization in the Eumsung county should change the strategy for local agriculture towards quality management of red peppers. and 2) the local government need to examine the feasibility of quality certifying on red pepper.

This study is on the organizational principles of Chinese traditional houses. It has been assumed that a common cultural background did influence dwelling construction in most areas of China, some specific concepts are used to build a connection between the culture and architecture. There are four aspects of cultural influence being explored: traditional concept of space by the philosophical influence, religious influence, the Feng Shut method, and traditional system of family organization. The influence of the Chinese culture on dwelling architecture is predominant. Housing types from different areas of China, despite their different physical appearance, have similar spatial concepts. This cultural influence was due to the historic development of the Chinese empire. The organizational principles of Chinese dwelling architecture determined by its own cultural background have five major invariable norms. They are as follows: 1. Internal and enclosed spatial organization. 2. Grouping of buildings around axes. 3. Spatial organization and extension by courtyard. 4. Spatial expansion by adding units. 5. Hierarchical organization of space.

1, The Purpose of Study This is a study on the Evaluation of the operating of Fisheries Extension Services of Korea, for performing the activities such as guiding fisheries technique as well as offering industrial information to the fishermen in fishing village. By doing so, the Fisheries Extension Sevices(FES) can materialize the continued growth of fisheries, the social and economic development of fishing village, and the increase in income by enhancing the knowledge level of Fishermen, etc. In performing fisheries policy, this activity plays a great role on the research and development activity, and it has become practical since 1976 in Korea. In order to meet immediately with the problem of fisheries technical innovation and rapid environmental changes surrounding the fisheries, the fishermen should not only enhance their scientific and comprehensive capacity in fisheries technique but abtain various effective information. Generally, as most of all the fishemen are poor in the managerial structure and scattered in fishing villages, they have little opportunity in the contact of information. As a result, it is nessessary for the FES to perform the fishing business by the extension service officials who has received special training and acquired fisheries know-how in these fields. And yet, FES is under the unfullfilled circumstance in such factors as manpower, technical know-how, equipment, and the service system etc., which is required in promoting the social, economic development of fishing village and in resolving the high technique demand of fisherman. This study on the fisheries extension services have been studied from those backgrounds. 2. Research Method The data of collecting methods which were necessary in carrying out this study was adopted by the questionaire research on the present extension service activity, through the subject of the extension services (driving agency of the work and the officials), the object(fishemen) and the 3rd observers to the extension services (the authorities concerned). The research sample was taken by the sampling extraction of total 1, 774 men from the above 3 groups. And the research was carried out from August, 1986 to October, 1986, supported from the Fisheries Extension Office (FEO) located in field during the research process. In this study, the levels of the extension operating were determined and estimated in accordance with the extension service method, morale of extension service officials and the extension service system, etc. through the collected data of the research questionaire paper. And based on this result, the essential conditions of the extension services were grasped, and also we tried to present the various activity plan necessary to promote the operating of the extension services. The questionaire research data was calculated by the computer center of National Fisheries University of Pusan, and the total result was again tried on the one demension analysis along with two dimension analysis to search out the relativity between the questionaire, and the statistical test was done $\chi$$^2$test in significance level of l~5%. 3. Contents of Study This study consists of 7 chapters and the contents are as follows : Chapter I : The object and method of the study Chapter II : The assessment and analysis of the extension services Chapter III : The contents and method of the extension services Chapter IV : Analysis of the essential conditions for the extension services Chapter V : The evaluation of activities of extension services Chapter Ⅵ : Conclusion.4. Results and RecommendationTherefore, the results of this study estimated by logical process and analysis are as follows : 1) Most of Korean fishing villages and coastal fishermen have shown much concerns about fisheries technique and social changes, thus many of them were confronted with new problems on how to adapt and to meet changes. 2) Majority of fishermen estimated FEO as an organization of specific technologies with all the thing concerning the fisheries technique in general. Therefore the fishermen wanted to utilize the FEO as an adaptable method for the modern fisheries techniques as well as the environmental changes. 3) In contrast with the fast changes of the fisheries technique, the complexity and variety of technical system and the broadness of fishing village and fishermen, it was revealed that the necessary factors such as the facilities, manpower, budget, and the level of applying techniques of the FEO located in field were highly insufficient. Accordingly, the guiding efficiency was low and the extension services did not provide full solution to the various request from fishermen. 4) It is possible to classify the activation factor for the extension service into two large dimension ; personal dimension relevant to guidance officials and work dimension relevant to the organization. And it was found that the activation level of the work dimension was far lower than the personal dimension between them. So, the activation should be done first in the dimesion to promote the activation of the extension services. 5) The extension services officials are now demoralized in general, thus it is necessary to take reality into consideration : the expense of activity, the adequate endowment of activity scope and the reasonable operation of the position class, etc to enhance its morale. However, in order to do the FES activation, first of all, the systems should be established which is lain unsettled stage until now. And there must be change in the understanding of government i.e. the fisheries extension services are the essential policy subject to build up the base of fisheries growth and modernize the fisheries management. And it should be driven positively with the recognition of the "lasting project".g project".uot;.
