Changing of industry structure and development of traffic and telecommunications requires a change of the knowledge about the space where the human beings reside. Step by step the world is being divided into specified utility blocks. Today there is a limit that only one local government can compete with another region in the world. This study provides decision support tools with the use of GIS on the regional level for regions competition. GIS establishes regions and analyzes their geographic environment data, which will help in local-government problem solving and provide framework data for similar regions to become the community. The wide-area GIS application can present an objective and rational basis for regulation of inefficient investments and excessive competition between adjacent regions. The study area is Gangwon-do. Considering specific features of Gangwon-do which preserved high-quality environment resources, river basins were taken as a basis among natural regional elements. The main object of analysis conducted were the facts relevant to environmental regulation. The Gangwon-do consists of three regions in this study: Yongdong region, North-Hangang region and South-Hangang region. The analysis of each region regulation cases showed the following: in Youngdong region the forests regulation rate is high, in North-Hangang region the military installations protection sector's rate as well as regulation rate for water resources protection is relatively high, in South-Hangang region the forest and water resources regulation rate is high. The percentage of forests and water regulation rate appeared to be rather high in Gangwon-do, which means that the value of forest and water resources there is very high.

This study was conducted to provide basic data in establishing a method for helping adolescents form the concept of correct oral health knowledge, by searching for their misconceptions about oral health knowledge and figuring out relevant factors. Results showed that they had appropriate knowledge on a relatively large number of questions regarding the level of oral health knowledge, but they also had misconceptions about the toothbrush grip, how to use medicines for gum diseases, and the project of fluorine concentration adjustment in water. It was shown that the score of oral health knowledge turned out to be 10.78 on average as a whole and the mean difference was within the error range. As for the correlations of misconceptions about oral health knowledge by group, it was noted that there were no differences in gender and education level, but those who completed oral health education had more appropriate concepts than those who did not (p < 0.001). In terms of the paths that they obtained oral health knowledge, the Internet and mass media (35.4%) had the highest rate and school (9.6%) had the lowest rate. With regards to the level of oral health knowledge, school had 10.56, which was the lowest score. In this regard, in order for adolescents to form adequate oral health knowledge, the following should be done. therefore, it would be necessary to activate school oral health education so as for adolescents to exercise adequate oral health behavior and to train many oral health educators so as for them to be provided with more educational opportunities.

The purpose of this research is to explore both on-site manager's and resident's assessment of the Automated Vacuum Waste Collection System (AVWCS) in suburban apartment complexes. In doing so, a self-administered questionnaire survey was conducted in 10 districts and their 11 apartment complexes in the Seoul Metropolitan Area. The main findings can be summarized as follows: the managers considered the AVWCS to be economically efficient and environmentally fiendly, and suggested that the system be managed in a more professional way, with an advanced technology and by more qualified technicians. The recommendation was related to residents' complaints and frequent mechanical failures frequently occurring in waste inlets and waste transport piping of the system. For residents using the system, the system was satisfactory, and should be necessarily improved with more user-friendly features. Further, most comments made by the residents were relevant to waste inlets such as safety, cleanliness, prompt repair, odor reduction, waste separation. It's of significant to train residents with how to properly use the system, which is expected to substantially fall a number of residents' complaints. Therefore, both professional management of AVWCS and regular workshops on how to utilize it are crucial in order to heighten its strengths.

With the request for the advent of new engine toward economic growth, the issue regarding public-owned data disclosure has been increasing. The Korean governments are forced to open public-owned data and to utilize them in solving the various social problems and in promoting the welfare for the people. In contrast, due to the distrust of the effectiveness for the policy, many public owned organizations hesitate to open the public-owned data. However, in spite of communication gap between the government and public organizations, Ministry of Government Administration and National Information Society Agency recently planned to accelerate the information disclosure. The study aims to analyze the perception of the public organization for public data utilization and to provide proper recommendations. This research identified mutual weights that the organization recognize in opening and sharing the public data, based on benefit, opportunity, cost, and risk. ANP decision making tool and BOCR model were applied to the analyses. The results show that there are significant differences in perceiving risk and opportunity elements between the government and public organizations. Finally, the study proposed the ideal alternatives based on four elements. The study will hopefully provide the guideline to the public organizations, and assist the related authorities with the information disclosure policy in coming up with the relevant regulations.

This study aims to develop a new analytical method to detect zinc pyrithione, the ingredient of cosmetics appointed as restricted ingredients and used as preservatives.. The analytical method was based on data gathered from the relevant literature. Information about the amounts of these ingredients was researched in order to select the base-matrix materials used to validate the analytical method. After selecting and preparing the base-matrix materials, the analytical method was validated by method validation procedures. The analytical method was verified first by inter-laboratory validation and then through analyzing the cosmetics sold in the market. Based on the results of this study, guidelines are proposed for the analysis of restricted ingredients in cosmetics, which will provide a method to test the cosmetics circulating in the Korean market. The use of the proposed guidelines will increase the quality of the cosmetics as well as the safety of human health, which will enhance the competitiveness of the Korean cosmetics industry and lead to an increase in the exportation of cosmetics.

When overland flow water is small and slow, it moves down a stream slowly and we use it as available resource. However, it could not only be good for nothing but arouse an inundation if a lot of runoff pour down to stream at a torrential rain. So it is important to know how much water to flow out and be stored in soil and on land in order to predict a flood and conserve soil and water quality. We intended to develop the prediction model of runoff in upland at a torrential rain and conducted lysimeter study in soybean cultivation and bare soil with 3 slopeness, 3 slope length and 5 soil texture from 1985 to 1991. The data of rainfall and runoff were used when daily rainfall was over 80 mm, the level of torrential rain warning. Minimum rainfall occurring runoff (MROR) was dependent on surface coverage and slope length. However soil texture and slopeness had a little influence on MROR. Runoff after MROR increased in proportion to precipitation which depended on surface coverage, soil texture and slope. Runoff ratio was larger in fine texture and bare soil than coarse soil and soybean coverage. Runoff ratio was in proportion to a square root of slope angle(radian) and reduced with slope length to converge a certain value. From these basis, we developed the prediction model following as $$Runoff(mm)=a(s^{0.5}+l^b)(Rainfall(mm)-80(1-e^{-bl}))$$ where a is a coefficient relevant soil hydraulic properties, b is a surface coverage coefficient, s is a slope angle and l is a slope length. The coefficient a was 0.5 in sandy loam and 0.6 in clay, and b was 0.06 in bare soil and 0.5 in soybean cultivation.

There are numerous drug interactions related to many psychotropic and cardiovascular medications. Firstly, the principles in predicting drug interactions are discussed. Cytochrome P (CYP) 450 plays a significant role in the metabolism of these drugs that are substrates, inhibitors, or inducers of CYP450 enzymes. The two most significant enzymes are CYP2D6 and CYP3A4. The ability of psychotropic drugs to act as inhibitors for the enzymes may lead to altered efficacy or toxicity of co-administered cardiovascular agents as a substrate for the enzymes. The following is also a review of the known interactions between many commonly prescribed cardiovascular agents and psychotropic drugs. Most beta blockers are metabolized by CYP2D6, which may lead to drug toxicity when they use in combination with potent CYP2D6 inhibitors including bupropion, chlorpromazine, haloperidol, selective serotonin reuptake inhibitors, and quinidine. Concomitant administration of lithium with angiotensin converting enzyme inhibitors, angiotensin receptor blockers, and diuretics may increase serum lithium concentrations and toxicity. Calcium channel blockers and cholesterol lowering agents are subject to interactions with potent inhibitors of CYP3A4, such as amiodarone, diltiazem, fluvoxamine, nefazodone, and verapamil. Prescribing antiarrhythmic drugs in conjunction with medications are known to prolong QT interval and/or inhibitors on a relevant CYP450 enzyme is generally not recommended, or needs watchful monitoring. Digoxin and warfarin also have warrant careful monitoring if co-administered with psychotropic drugs.

Abalone aquaculture has developed very rapidly in Korea. Until the mid 1990s it has annually produced about 100 tons. Since then the yield has increased to about 9,000 tons in 2012. The amount accounts for 20% of the global abalone yield. About 86% of produced abalone is consumed domestically and the rest is exported. 100 tons for export seemed as an unattainable goal back in 2003. However, the export rose up to 1,333 tons in 2012. Despite its rapid growth, Korean abalone industry is faced with some problems. The first is the slowdown of yield increase rates. Abalone production increased by 50~60% until the mid 2000. However, the rate continued to drop to below 10%. Reasons behind the slow increase are deteriorating aquaculture grounds and worsening market problems. Constant aquaculture aggravated productivity and overcrowded facilities at a limited space made matters worse. Moreover, abalone export has stalled and so did domestic consumption. In the meantime, rising mortality of young abalone has lowered productivity at abalone breeding places. The mortality rates of abalone remained below 5% in the early 2000s but rose to 30~40% these days. This translates into rising abalone prices. The market problems imply stagnant or shrinking export as well as domestic consumption. The export increase rates took a nosedive from 200 to below 50 between the early 2000s and the late 2000s. Moreover, the increase rates of domestic consumption have become remarkably sluggish. According to, it stood at 50~60% in the mid 2000s but continued to decrease after 2008. These problems, in turn, affected the size of abalone. The usual abalone size for market was 10~12 shells per kg, but recently the size became smaller and smaller to 15~16 shells per kg. The change of size implies shift in consumption patterns: Consumers not only eat live abalone but also they cook soup with it. The size of abalone for uncooked dish is usually very big, like 10~12 shells per kg. In contrast, smaller abalone, such as 20~25 shells per kg, are used for making soup. Increasing use of smaller abalone leads to lower income of abalone aquaculture households. This is partly because that the size determines the price and the price gap between big abalones and smaller ones is extreme in Korea. For the sustainable growth of Korean abalone industry, we need to come up with strategies. First, a reasonable production system needs to be in place, especially for better management of abalone aquaculture grounds. Management of abalone licenses is also necessary because local governments issue relevant licenses as well as supervising abalone grounds. Second, abalone export destination need to be diversified. Japan, the major importer of Korean abalone, takes up a lion's share of export, at 95%. Third, new consumption style of abalone needs to be developed. Abalone used to be consumed as 'raw type' or Sashimi in Korea. This sole type of consumption hampers the growth of abalone market. Moreover, more strategies are needed to encourage and distribute home cooking of abalone rather than eating-out at restaurants. Last but not least, distribution system should be improved for better delivery of live abalone.
