The purpose of this research is to target the health examination examinees to compare and analyze the common elements that influence prevention and preventive medical services and to analyze the share of the physical examination categories desired following the analysis by element. Likewise, this research was attempted to provide base data so that it is possible to reduce cost required for the prevention and treatment of each examination. This research targeted health examination examinees and conducted survey from April 1to May 31, 2010. The key findings after conducting analysis on 707 examinees are as follows. In case of men, those who are older and who live their spouses tended to be subjected to health examination, cancer examination and preventive injections. Those who had subscribed to the medical policy from the private sector, those with healthy state, those with higher educational level, tended to get health examination, cancer examination and preventive injections less. In case of women, those who are older, tended to get health examination and cancer examination more while those who had subscribed to the medical policy from the private sector and those with higher educational level tended to get health examination, cancer examination and preventive injections less. Those who are healthy and who live their spouse tended to get more cancerexamination and preventive injections.

We tried to find out the technological innovation properties of the National Research and Development Projects (NRDPs) through scientometric analysis of patent data generated by the NRDPs. The distribution of technology groups in patent data shows that NRDPs are highly focused on the Information Technology(IT) group. The Relative Cites Index(RCI) analysis implies that the Biotechnology(BT) group will emerge in the future. The Relative Family Indices(RFIs) are high among the high technological impact groups such as BT and IT. We defined new measures related with technological convergence and collaborativenessopenness relations among R&D agents. Using network analysis techniques, we analysed the absorption-derivation relations among technology groups and the opennesscollaborativeness relations among R&D agents. Recently, both the share of hetero-plural technology groups and the collaboration among different R&D agents are increasing.

The fraction concept consists of various meanings and is one of the abstract and difficult in elementary school mathematics. This study intends to find out the implication for introducing the fraction concept by comparing mathematics textbooks of Korea and Singapore. Both countries' students peformed well in recent TIMMSs. Some implications are as follows; The term 'equal' is not defined and the results of various 'equal partitioning' activities can not easily examined in Korea's mathematics textbook. And contexts of introducing fractions as a quotient and a ratio are unnatural in Korea's mathematics textbook in comparison with Singapore's mathematics textbook. So these ideas should be reconsidered in order to seek the direction for improvement of it. And Korea's textbooks need the emphasis on the fraction as a measure and on constructing fraction concept by unit fraction.

The paper uses a panel gravity model to analyse the determinants of export via Gwangyang port for the period from 2000-2012. The gravity model includes export via Gwangyang port, GDP and population of trading partners, the distances between Korea and its partners, and Korea-ASEAN FTA dummy. Hausman test shows up which one is exactly appropriate between random effect estimation and fixed effect estimation to use panel dataset. It depends on whether or not existence or nonexistence of the correlation between unobserved omitted factors and variables. Fixed effect estimation is suitable for this paper by the rejection of null hypothesis. An Empirical analysis of this paper shows GDP influences positive effects and distance influences negative effects to Gwangyang port trading partners. In addition, the results strongly supported the effects of Korea-ASEAN FTA on the growth of Gwangyang port export.

Korean management agency and production's size is bigger than ever applying diversification strategy since the Korean Wave started in 2000. Thus, the cross-ownership between two sectors is widespread and it's side effect such as unfair trading occurred among them. Came up with this problem, this study has focused on the analysis of the cross-ownership status of the entire Korean listed agencies and productions and the quest of the alternatives to solve the problem through in-depth interviews of the stakeholders and experts. Results showed that the horizontal regulation and American regulatory systems should be applied considering the previous law because the cross-ownership level was so high. In conclusion, it was proposed three regulatory models as follows : first, accept the cross-ownership and prohibit casting their contracted actors in their art, second, ban on the cross-ownership and allow mutual investment within a 10 to 20 percent stake, third, blanket ban on the cross-ownership and investment.

The purpose of this study was to examine the effects of participation in a forest program on the level of depression changes in the participants. Total of 501 university students residing in the middle province of Korea were administered Beck Depression Inventory(BDI). Among them, 32 students were selected as participants of the program based on the scores of the BDI. A 5-day forest program included climbing, sharing experience with others and so on. Pre and post tests control group research design was employed for this study, with BDI measures taken from each of 32 participants on three time frames : 2 weeks before the program, immediately before participation, and immediately after participation. BDI scores were expected to decrease as a result of forest program participation. The study results supported this hypothesis.

This study analyzed backward and forward linkage effects among Korea, China and Japan by International Input-Output(I-O) tables. Index of dispersion power and sensitivity degrees were measured after making 'Korea, China and Japan International Input-Output(I-O) Table'. The study showed that the inter-dependency between Korea and China was increased while the influences of Japanese was decreased among the 3 countries. Under the de-industrialization, the 3 countries decreased influences over their domestic industry but increased the inter-dependency over the other countries. In addition, backward and forward linkage effects was significantly high in some industrial sectors such as petroleum, transportation, machinery equipment, service and public administration in 3 countries. In the case of service, the linkage effects among the 3 countries increased which means that the roles and inter-dependency of service was also gradually increasing in 3 countries.

Logistics industry was changed after China join into the WTO. Compared with other countries, cost of logistics is very high in China. Besides, there are several problems with the demand basis, service and information technology of the third-party logistics. The forth-party logistics was appeared in logistics market in this context. The forth-party logistics was just become to develop in China so there are many problems recent years. Chinese government propose some solutions with the development of the fourth-party logistics such as the adjustment of the logistics industry policy, strengthening of the logistics information system and infrastructure, training logistics expertise. This research pointed out the obstacles in the development of the forth-party logistics in China by analyzing the present situation and the development strategy of some representative companies such as ANDE Logistics Company and Philips Logistics Company. The purpose of this paper is to research the development of the forth-party logistics in China by analyzing the problems with Chinese government and logistics companies, and finally bring up some solutions with these problems.

DEA(Data Envelopment Analysis) is useful to measure the relative efficiency of organizational units where the presence of multiple inputs and outputs. This study applied DEA-CCR and DEA-BCC to evaluate the technical, pure technical, and scale efficiency of 29 university libraries. The input variables were number of books, print edition expenses, building space, staff, number of seats. As output variables we estimated: reader visits, number of borrowed items, number of visitors. It was found out that number of libraries with 100% relative efficiency among 29 libraries were 13. Also the results shows that main reason of inefficiency was from scale rather than from pure technical. Many inefficient libraries were operations of increasing return to scale.

The glasses, which the $\beta$-spodumene as the principal crystalline phase could be precipitated, were melted by adding >, $P_2O_5, TiO_2, ZrO_2 in the Li_2O-Al_2O_3-SiO_2$ system. In order to achieve the glass-ceramic body of near-theoritical density by sintering method, the optimum condition of heat treatment, the effect of glass powder size and the properties were investigated by DTA, XRD, bulk density, thermal expansion and SEM. Addition of $P_20_5$ imProved the tendency of sintering and the sample with 9wt% $P_20_5$ content was the most dense OOdy by sintering method. The optimum condition of heat treatmemt was sintered for densitification at $740^{\circ}C$ and crystallized at $950^{\circ}C$. In the optimum condition, the relative density was above 90% and the thermal expansion was negative about $-1{\times}10^{-7}/^{\circ}C$.
