This study is a basic study to prepare policies related to selecting media to be included in textbooks. Researchers looked at previous studies focusing on how media affect children's and adolescent's emotions according to their developmental stages. Researchers also wanted to identify how the media is related to student emotions, health, and educational effectiveness. The researchers then examined a wide range of domestic media review and rating criteria, and argued that it is necessary to institutionalize the rating system of media at national level policy level. Based on the previous discussion, the researchers made seven suggestions. First, it is necessary to specify media selection criteria in the guidelines for issuing textbooks at the national level. Second, guidelines are needed to help review the political neutrality and human rights aspects of the media for inclusion in textbooks. Third, media selection guidelines in textbooks should be detailed with reference to categories and age based criteria of domestic and foreign media rating system. Fourth, the media rating system should be applied flexibly if there is a clear educational purpose. Fifth, institutional support is needed for setting guidelines for media collection of textbooks. Sixth, media experts should participate in the whole process of textbook development. Seventh, educational programs should be implemented to support teachers to use self directed learning by using educational media in classroom instruction.

The purpose of this study was to improve forestland characteristic evaluation system's indicators for rational development and ecosystem conservation. There has been no consideration for statistical duplication between variables, and it caused inefficient data collection. Furthermore, the same evaluation criteria were applied for all forestlands without considering regionally different characteristics, and it made variation for designation cancel rates of preservation semi-preservation forestlands between cities. To solve these problems, we first removed 'DBH' variable which has a multicollinearity. Second, we applied standard normal distribution for each forest watershed type. As a result of eliminating 'DBH', the numbers of parcels for all grades except A were changed but their numbers and areas were not large enough to consider the change of total score. For the output of analyses with the existing same regional criteria, the total scores of urban type and urban-fringe type forestlands were higher than those of other types. The numbers of parcels for A and B were increased and those for C and E were decreased by applying standard normal distribution. This caused the increase of preservation-oriented parcels. Finally, we suggested a new evaluation method based on standard normal distribution to consider regional forest characteristics and to solve regional imbalance.

The western cherry fruit fly, Rhagoletis indifferens Curran (Diptera:Tephritidae), is the most important pest of cultivated cherries in the Pacific Northwest area of the United States, being widely distributed throughout Oregon, Washington, Montana, Utah, Idaho, Colorado and parts of Nevada. The control of R. indifferens has been based on calendar sprays after its first emergence because of their zero tolerance for quarantine. Therefore, a good prediction model is needed for the spray timing. This study was conducted to obtain the empirical population dynamic information of R. indifferens after overwintering in the major cherry growing area of the Pacific Northwest of the United States, where the information is critically needed to develop and validate the prediction model of the fruit fly. Adult fly populations were monitored by using yellow sticky and emergence traps. Larvae growth and density in fruits were observed by fruit sampling and the pupal growth and density were monitored by pupal collection traps. The first adult was emerged around mid May and a large number of adults were caught in early June. A fruit had more than one larva from mid June to early July. A large number of pupae were caught in early July. The pupae were collected in various period of time to determine the effect of pupation timing and the soil moisture content during the winter. A series of population density data collected in each of the developmental stage were analyzed and organized to provide more reliable validation information for the population dynamic models.

'In the age of information, invasion of personal information resulted from the development of information and communication technology is one of the greatest problems all the countries in the world face. Therefore, Personal information protection Act is one of basic laws to protect personal information and rights and it is also an essential law in the age of information. In that sense, new Personal information protection Act is the advanced act containing various items to minimize the national damages from the leaking of private information and protect right to informational self-determination in the information society. It is expected that this legislation contributes to reduce the leaking of private information, enhance the level of privacy protection and develop privacy related industries. However, active participation of all members of our society and improvement of their recognition should be preceded for the rational and legal use of private information and the settlement of its protection culture. While the purpose of Personal information protection Act can protect privacy from collection, leaking, misuse and abuse of private information and enhance national interests and protect personal dignity and value, it also must perform the roles of balancing privacy protection with liberal information flow.

In today's data-driven society, we've been hearing a great deal about the power of Big Data over the last couple of years. At the same time, it has become the most important issue that the problems is caused by the data collection, management and utilization. Moreover, Big Data has a wide applications ranging from situation awareness, decision-making to the area to enable for the foreseeable future with man-made and analysis of data. It is necessary to process data into meaningful information given that the huge amount of structured and unstructured data being created in the private and the public sector, even in disaster management. This data should be public and private sector at the same time for the appropriate linkage analysis for effective disaster management. In this paper, we conducted a literature review and case study efficient Big Data to derive the revitalization of national disaster management. The study obtained data on the role and responsibility of the public sector and the private sector to leverage Big Data for promotion of national disaster management plan. Both public and private sectors should promote common development challenges related to the openness and sharing of Big Data, technology and expansion of infrastructure, legal and institutional maintenance. The implications of the finding were discussed.

The purpose of this study is to identify the citing behaviors of researchers in the field of mechanical engineering. It tries to verify if there is a significant difference on citing behavior of researchers between the past and the present with dissertations produced in P University as samples. For the comparison, years 1996 and 2004 are selected for the citation analysis. It analyzed four aspects, such as types of resources cited, languages used in cited documents, years since their publication of cited documents, and the journals indexed in SCI. The results of the analysis are; First, journals are the most cited than any other types of information resources. The citation of WWW resources which are gradually increasing for research is not shown in 1996, but there were some cited in 2004. Second, doctoral candidates usually cite document in English for their study. Statistics show that the use of resources in Japanese is on the decrease. Third, doctoral candidates in the discipline prefer materials published within 4-7 years, 8-11 years rather than 0-3 years since their publication. Last, journals indexed in SCI among the citation in dissertations are about 33 percent for both 1996 and 2004.

An attempt was made to find out the possibility of utilizing water-melon seed as resources of food fats and protein. The water-melon seed contained 40.40% of crude fat and 28.36% of crude protein. The lipid fraction obtained by silicic acid column chromatography was composed of about 97.35% neutral lipid, and the main components of neutral lipid by thin layer chromatography were triglyceride(50.40%), diglyceride(21.84%) and sterol(11.48%). The predominant fatty acids of total and major lipid classes were linoleic acid(55.30-67.85%), palmitic acid(12.07-28.12%) and oleic acid(9.06-16.40%), whereas stearic acid and linolenic acid were detected as small amounts. The salt soluble protein of watermelon seed was highly dispersible in 0.02M sodium phosphate buffer containing about 0.7M $MgSO_4$, and the extractability of seed protein was about 27%. Glutamic acid and arginine were major amino acids, and the essential amino acids such as lysine, threonine, valine, methionine, isoleucine, leucine and phenylalanine were also detected. The electrophoretic analysis showed 6 bands in water-melon seed protein, and the collection rate of the main protein fraction purified by sephadex G-100 and G-200 was 52.4%. The amino acids of the main fraction protein were also mainly composed of glutamic acid and arginine. The molecular weight for the main protein of the water-melon seed was estimated to be 120,000.

Objectives: This research was done to identify relationships among job stress, fatigue, job satisfaction, and commitment to organization in customized home health care nurses. Methods: Research participants were 130 nurses who worked in the customized home health care of 20 county in Gyeongnam province. Data collection for this descriptive correlational study was done at August 2010 using self report questionnaires, and analyzed using descriptive statistics, t-test, ANOVA, and we analyzed a four step approach in which several regression analyses were conducted and significance of the coefficients is examined at each step. Results: The results from step 1 showed that, the effect of each job stress was significantly related to job satisfaction. In step 2, the direct effect of commitment to organization on job satisfactions were all significant too. Step 3 analysis showed that the total effect of each job stress on commitment to organization symptoms was significant. Step 4 showed the results of controlling for mediating factor (job satisfaction): job demand and insecurity were significantly associated with commitment to organization(p<0.001), the finding supports that others were fully mediated by each job satisfaction, and, the job demand and insecurity were partially mediated by job satisfaction. Conclusion: Results of this research indicated that job stress in customized home health care nurses was the principal variable affecting job satisfaction and commitment to organization. Appropriate stress management strategies based on assessment of job demand and job security for these nurses lead to development of improved commitment to organization.

Floating and hatching rates, size and survival activity index(SAI) of spawned eggs of red spotted grouper, Epinephelus akaara were studied to understand egg qualities during the spawning periods in 1992, 1993 and 1995. The fish spawned from mid-July to mid-August when temperature ranged 23~$28^\circC$. Floating, fertilization and hatching rates were higher in the eggs from early to middle than those from late during the spawning period. SAI ranged 1.8~9.6, and it was closely related to survival rate until mouth operning time (SMOT). Egg diameter decreased gradually with the time of spawning, while diameter of oil globule was constant during the spawning periods. Induced spawnings were carried out with one injection of HCG over 5, 000 IU/kg body weight. Floating, fertilization and hatching rates of the induced spawning eggs were higher than those of untreated ones. Thus, induced spawning method with HCG was recommended for collecting fertilized eggs in bulk. Optimal time for the collection of high quality eggs was supposed to be from early to middle during the spawning periods. Considering that egg qualities were vulnerable within the period, hatchability, incidence of malformed larvae, SMOT and SAI were factors to be considered together to get good quality of eggs.
