Burglary (also called breaking and entering and sometimes housebreaking) is a crime, the essence of which is illegal entry into a building for the purposes of committing an offence. It is one of the most common types of crime and also a serious issue for every society. A house that is left insecure is an accessible and attractive target for burglars and therefore burglary resistance test & certification system for doors and windows has been developed in many countries. This paper explores several advanced foreign burglary resistance test/certifcation cases (the British SBD, the Dutch KOMO SKH/SKG, the Japanese CP mark, the Australian Standard Certification) for security products and domestic test/certification systems for fire safety products as a comparative study so that any improvement points can be gained for South Korea in the field of security product performance. The comparative analysis results show that South Korea is far behind the security product certification system and needs a lot of improvement in the system by benchmarking foreign cases. The domestic test/certification systems for fire safety products also give some insights for burglary-related security products' performance certification system in Korea. Overall, the need for relevant rules and regulations, the establishment of standards regarding testing and certification, including certified security +hardware product in building security certification system, performance testing as well as production testing (i.e. quality management system evaluation), the basic competency of testers, incentive system for certified/high quality security products were suggested in order to make an optimal model for the security production performance testing and certification system in Korea.

The study was conducted to investigate the effects of practical variations in feed restriction, pre-slaughter handing and chilling regime on pork quality during ageing. A total of twenty male landraces were allocated into three treatments(i.e., pre-slaughter feeding, stress and chilling regime) in a factorial arrangement. pH, temperature, free calcium ions, WB-shear force, sarcomere length, cooking loss, drip loss and objective color were determined during rigor development and/or 1, 3, 7 d postmortem. Pre-slaughter chasing stress for approximately 15 min had no effects on pH/temperature profile and objective meat quality. There was an interaction(P < 0.05) between the fasting treatment and chi1ling regime for muscle temperature at pH 6.2. Sarcomere length indicated that the current experiment conditions did not induce muscle shortening, with 1.7 to 1.8 ${\mu}m$, in spite of a significant effect of the fasting treatment (P<0.01). Pigs fed until the morning of slaughter showed a low WB-shear force(P < 0.05) until 3 d at I "C. The treatment also resulted in a higher Hunter L* and a*(P < 0.05) at 24 h and 7 d. Fasted pigs showed a significantly(P < 0.05) reduced cooking loss. The current results indicated that feeding upon the morning of slaughter became detrimental on meat color and the negative effect on cooking loss were linearly elevated with increased ageing time. On the other hand, WB-shear force did not distinguishable after 3 d. Collectively, it appeared that feed restriction from a day before slaughter could produce more a desirable meat quality at the time of consuming. However, the limited effect of animal handling and chilling rate on meat quality is not necessarily to extend to that these do not affect pork quality, as that largely depends on experimental design.

This study was performed to support the 6th forest basic planning by Korea Forest Service as predicting the change of forestland area by the transition of land use type in the future over 35 years in South Korea. It is very important to analyze upcoming forestland area change for future forest planning because forestland plays a basic role to predict forest resources change for afforestation, production and management in the future. Therefore, the transitional interaction between land use types in future of South Korea was predicted in this study using econometrical models based on past trend data of land use type and related variables. The econometrical model based on maximum discounted profits theory for land use type determination was used to estimate total quantitative change by forestland, agricultural land and urban area at national scale using explanatory variables such as forestry value added, agricultural income and population during over 46 years. In result, it was analyzed that forestland area would decrease continuously at approximately 29,000 ha by 2027 while urban area increases in South Korea. However, it was predicted that the forestland area would be started to increase gradually at 170,000 ha by 2050 because urban area was reduced according to population decrement from 2032 in South Korea. We could find out that the increment of forestland would be attributed to social problems such as urban hollowing and localities extinction phenomenon by steep decrement of population from 2032. The decrement and increment of forestland by unbalanced population immigration to major cities and migration to localities might cause many social and economic problems against national sustainable development, so that future strategies and policies for forestland should be established considering such future change trends of land use type for balanced development and reasonable forestland use and conservation.

Recently interest in infection control is increasing in hospitalsnfection control has become more important in the overall health care practiceental hospital also requires thorough infection control. There are various kinds of vectormedical clothing. Contaminated clothing of a hospital staff can be a vector of nosocomial infecton. actual case of nosocomial infecton caused by contaminated medical clothing, nursing students were measuring contamination levels of uniforms and pathogenic microorganism wdetected in front of the uniform and pocket. There is also a high risk of exposure to contamination in the dental hospital. We conducted a study to enhance awareness about infection and proper clothing management by comparing before and after contamination of clothing caused by aerosols produced during scaling. Subjects were scaling operators' uniforms in the department of dental hygiene, K University located in Daejeon. Before scaling, the uniform was sterilized by autoclavecaling was performed times in the same place (an average of 60 minutes per person, a total of 180 minutes). ive parts of the uniform (sleeves, chest, belly, thigh, edge of pants) contracted Rodak-plate for 15 seconds. After incubating the contacted Rodak-plate at 37℃ incubator, contamination levels by measuring the number of colonies. As a result, all parts increased number of colonies. ontamination order chestedge of pants thigh belly sleeves. Increase rate of colonies was also high in the order chest edge of pants thigh belly sleeves. This study showed seriousness of clothing contaminationcaused by aerol produced during scalingcontamination of clothing can be a path to nosocomial infecton. According to th study, infection control for clothing as well as dental instruments should be implemented and thorough infection control training needed for dental staff. In further researches, practical infection prevention supplementing clothing management method.

Social obligation of a nation must be assigned to the people, legally belong to the nation. The Republic of Korea assigns a social obligation to the Koreans, the Military Service which is regulated by the Constitution of the Republic of Korea and the Military Service Law of Korea. However, behind the law, a serious discussion, the rationality and equity, is possibly discovered from the reality of the military service system against athletes of Korea. The purpose of this study was to analyze the military service system against athletes of Korea based on the Constitution of Republic of Korea and the Military Service Law of Korea. Three proposals, prohibit duplicated benefits of athletes, military service evasion after care system and keeping the military and police sport organization as nonprofessional, to recover the institutional problems regarding the equity and rationality were suggested in the end of this research. With the results, this research hopefully contribute to the development of sport law, fundamental obligation with sports and the military service system on athletes in Korea.

Amid the importance of design is being emphasized as a new barometer for boosting enterprise competitiveness, high expectations are being placed on design consulting that evaluate design from a comprehensive perspective. SMEs, however, are not easy to gain access to design services compare to their counterparts - large companies. This will eventually cause them to ignore the importance of design, not to mention lack of financial resources for investing in design. With this regard, the paper analyzed the design status and design consulting performance of SMEs in industrial complex through the 2012 Design Innovation Project in Industrial Complex of Busan Design Center; also analyzed the effect of design consulting on improving competitiveness of SMEs as well as design awareness. As a result, the study found that a majority of companies do not invest in design or postponed investment, despite they are not satisfied with their design performance. However, 65.6 percent of SMEs that realized the importance of design after consulting have carried out design development, which brought about sales increase through their improved corporate images and product images. We believe design consulting played an important role for boosting awareness and competitiveness of SMEs. Eventually, we need to provide an intensified design analysis process that can facilitate SMEs. Design consulting support projects should offer practical design development programs through continuous follow-up, including interaction with state projects and design-specialized companies.

There is a need to restore the terrain back its natural environment after mining development. It is necessary to compare the original and developing surfaces for post-management and to analyze the terrain change to develop a process for efficient restoration plan. This study analyzes and compares change to the terrain by annual mining development using GIS. Contours digitized with CAD based on photogrammetry are classified into annual data and created by Triangulated Irregular Network (TIN). By producing profiles and cross sections using TIN, many stations are distinguished. As a result of the terrain changes caused by mining development from 2000 to 2003 by operating elevation values each cell converted to raster from TIN, $11,094,460m^3$ are cut and $5,127,968m^3$ are filled up to 46% of cut volume, and annual surface changes of cut and fill area to mining are analyzed to visual and quantitative data. This study is used for the restoration plan and additional mining. And it is expected that this annual change, caused by mining development, can be used to return the terrain close to its original condition for finished mining area.

Heavy metals leaching from closed mines have been causing severe environmental problems in nearby soil ecosystems. Mine reclamation in Korea has been recently implemented based on the heavy metal immobilization (a.k.a., stabilization). Since the immobilization temporarily fixes the heavy metals to the soil matrix, the potential risk of heavy metal leaching still exists. Therefore the appropriate monitoring and the related policies are required to safeguard the soils, where all the cultivations occur. The current monitoring methods are based on either heavy metal concentration or simple toxicity test. Those methods, however, are fragmented and hence it is difficult to evaluate the site in an integrated manner. In this study, as the integrated approach, ecological functional state evaluation with a multivariate statistical tool was employed targeting physiochemical soil properties, heavy metal concentrations, microbial enzymatic activity, and arsenic respiratory reductase gene quantity. Total 60 soil samples obtained from three mines (Pungjeong, Jeomdong, Seosung) were analyzed. As a result, the stabilized layer soil and lower layer soil have shown the similar pattern in Pungjeong mine. In contrast, Jeomdong and Seosung mine have shown the similarity between the stabilized layer soil and the cover layer soil, indicating the possible contamination of the cover layer soil.

This research is for examining the effect on personal health and differences between men and women by health care program in security guards and students, who are specializing security in college, appealing consciousness state physically and mentally. The following results are attained by conducting a questionnaire survey(T.H.I) of 358 men engaged in security guard services and 220 students specializing security (The data analysis is operated by Analysis of Variance(ANOVA) to make a comparative study of health care program, sex distinction and security careers. The implication of the study are as follows. 1. Generally students show less average rate than security guards in appealing the consciousness state especially in Mental Irritability, Irregular Life, Depression, Respiratory, Eyes and Skin, Aggressiveness. 2. In comparing men with women of consciousness state after the step of health care program, men show lower average rate than women except Life Scale and Respiratory. 3. In differences of consciousness state by security career, the more respondents have careers, the less the average rate of Mental Irritability and Depresaion is. But in Life Scale, the result is reverse.

The pedigree data of 86,639 heads from six major swine breeding farms were investigated to check levels of inbreeding and effective population size of breeding stocks. The average rate of inbreeding was 1.04%, 0.87%, 3.17%, 1.05%, 3.23% and 3.33% for farms A, B, C, D, E and F, respectively. The average inbreeding rate was highest for F farm and lowest for B farm. In farms D and E, there were quite large numbers of immigrant animals per generation compared to other farms. The effective population sizes calculated from the average rate of inbreeding were distributed between 83.0 and 814.8. Specific values were 282.3, 225.5, 83.0, 814.8, 302.9 and 175.7 for farms A, B, C, D, E and F, respectively. The results showed that there was no cause for concern over the current inbreeding level of major swine breeding farm populations and the inbreeding level was within an acceptable range. In addition, internal sharing rather than importing pig is necessary to strengthen seed sovereignty.
