As people are more concerned about their health and medical care, there have been an increasing number of medical disputes due to increased medical demand. In order to prevent and provide solution to currently surging medical accidents and disputes related to orthodontic treatment, in July 1998, the Korean Association Of Orthdontists surveyed 2,200 members of Korean Association of orthodontists on 30 items to recognize the pattern of medical accidents and prevent them. The survey was about accident-related items including personal profiles of members and patients who have undergone medical accidents or disputes, the cause and solution to the accidents, cautions related to members orthodontic treatment, and medical recording and archival. Based on the survey result, we analyzed characteristics of medical accidents and disputes in orthodontic area. It is more important to predict and prevent possible medical accidents or disputes based on current situation than to solve them after disputes occur. For this, we should not be negligent in raising treatment proficiency level based on patient-doctor trust and in obtaining new medical information. We should also provide medical environment where Patients themselves can decide whether to get treatment after they are offered detailed explanation on diagnosis, treatment procedure, complication, and possible hazard. We should take caution when treating patients and pay attention to charting and maintenance, which is the most fundamental, as well. Also at the Korean Association of orthodontists level, it is desired to provide education program on prevention and solution to medical accidents and disputes, and actions and organizations that can help when accidents and disputes occur.

The meaning of the mentee's experiences who participated in the mentoring program for freshmen of department of early childhood education The purpose of this study was to find the mentee's experiences and the meaning of mentee's experiences who participated in a mentoring program. The participants were 13 freshmen of early childhood education department in a three-year junior college. The data was collected through journal, open questionnaire, interview from March 21st to September 9th in 2010. The data was analyzed by segmenting, primary coding and depths coding. At the first session the mentees experienced complicated feelings, expectation of relationships with their mentors and acquired a lot of information from the mentoring program. Through the whole program mentees learned and executed many things: a time management, a good presentation skill, a reference searching way, preparation for exam, and career management. However, they felt sorry for that there was not informal meeting with their mentors. They thought the experience lucky, which is very difficult to have. So they want to give the experience back to their mentors and future mentees. They suggested advanced mentoring program based on their experiences as well.

The ecophysiological characteristics of the oyster Crassostrea gigas in Taean area, west coast of Korea, were investigated after main spawning season from September 2011 to January 2012 to confirm the recovery process of condition. The cupped oysters, from 4 different off-bottom culture areas were compared the gonad indices, histological analysis combined with measurement of RNA/DNA contents and ratios in gonad of each sex were undertaken. To evaluate the health condition of oyster after spawning, the RNA/DNA ratio in adductor muscle, fatness and condition index (CI) were used. The results showed that cupped oysters cultured in Uihang coastal area were different physiological aspects than other experiment areas, namely continuously decreasing RNA/DNA content and ratio in adductor muscle, lowest CI and fatness. Oysters cultured in Iwon Station 1 and 2 showed fast recovery in RNA/DNA, increase in fatness and CI during post-spawning stage until October rapidly and there after it decreased. Oysters in Shinduri showed rapidly decrease in fatness and CI until October. On the contrary to this factors, RNA/DNA ratio in adductor muscle increased as like protein until October. Partially spawning season could be observed until December in Shinduri and Iwon Station 1.

The purpose of this study is to investigate the recognition of food allergies and dietary attitudes in elementary school students. For the food allergy symptoms, they responded 'skin trouble' 63.6% the most. For the causing foods of allergies, they responded, 'I don't know the causing foods' 33.5%, 'I was diagnosed' 51.0%, 'I was treated' 63.9%, and therefore 'I restricted foods' 53.5%, due to 'I restricted foods through hospital diagnosis' 40.5% the most. For family history, 67.9% responded the family history matters. 70.3% responded the seasons would not affect to the symptoms. 64.1% responded the cause of food allergy is specific foods. For allergy solution, they responded, 'I don't use any treatment' 42.8% the most. For effective treatment, they responded, 'I restricted causing foods' 45.1% the most. Recognition of food allergies by food allergy experience showed a significant difference in the items such as 'have heard or known about food allergies'(p<.001), 'whether participated in consultation and training'(p<.001), 'problems of growing children when putting limits on causing foods'(p<.001), 'interests in getting information about food allergy'(p<.001), 'feeling the needs of allergy education about careful foods'(p<.01), 'wish for schools to be educated'(p<.01). Dietary attitudes by food allergy experience showed a significant difference in reason of unbalanced diet(p<.001).

Objective: This study inspected incident cases, legal control levels, and GHS(Globally Harmonized System of Classification and Labeling of Chemicals) classification results of strong acids such as hydrogen fluoride, hydrogen chloride, nitric acid, and sulfuric acid, which have been responsible for many recent chemical accidents. As a result, it is deemed necessary for legal control levels of these strong acids to be revised and GHS classification be managed nation-wide. Methods: This study inspected incident cases and legal control levels for strong acids such as hydrogen fluoride, hydrogen chloride, nitric acid, and sulfuric acid. The study analyzed and compared chemical information status and GHS classification results. Results: There were 76 domestic incidents involving strongly acidic hazardous materials over the five years between 2007 and 2011. They include 37 leakage incidents(46.7%) within a workplace, 30 leakage incidents(39.5%) during transportation, and nine leakage incidents(13.8%) following an explosion. The strongly acidic materials in question are defined and controlled as toxic chemicals according to the classes of Substances Requiring Preparation for Accidents, Managed Hazardous Substance, Hazardous Chemical(corrosive) as set forth under the Enforcement Decree of the Toxic Chemicals Control Act and Rules on Occupational Safety and Health Standards of Occupational Safety and Health Act. Among them, nitric acid is solely controlled as a class 6 hazardous material, oxidizing liquid, under the Hazardous Chemicals Control Act. The classification results of the EU ECHA(European Chemicals Agency) CLP(Commission Regulation(EC) No. 790/2009 of 10 August 2009, for the purposes of its adaptation to technical and scientific progress, Regulation(EC) No 1272/2008 of the European Parliament and of the Council on classification, labeling and packaging of substances and mixtures) and NIER (National Institute of Environmental Research) are almost identical for the three chemicals, with the exception of sulfuric acid. Much of the classification information of NITE (National Institute of Technology and Evaluation) and KOSHA(Korea Occupational Safety and Health Agency, KOSHA) is the same. NIER provides 12(41.4%) out of 29 classifications, as does KOSHA.

This study investigates the relationship between the purchasing behavior for hair-care products and the attitude toward hair-care products by adolescents. A total of 412 middle and high school students located in Seoul and Gyunggi-do province participated in this research. SPSS 12.0 for Windows Program was utilized for statistical analysis. As a result, the hair concerns and the satisfaction of adolescents as well as their attitudes towards hair-care products were significantly affected by gender, school level, and educational experiences. Female high school students with some degree of educational experiences had a more rational and brand-oriented attitude. Students having a higher rational and brand-oriented attitude bought hair-care products in regards to the quality of the product and environmental impact. On the other hand, those having a conspicuous and fashion pursuit attitude showed an image and fashion concern purchasing behavior. Adolescents usually purchased styling and dyeing products at a cosmetic specialty store and hair-care cleaning products from a discount store. They obtained the information about hair-care products from relatives, personal experiences, and TV advertisements.

In construction site, BIM is used in part of construct-ability review and design mistake checking. However, in a current domestic construction site, except public order project, most of work in private order project has been processing based on 2D work. As an expert resists to certain point in introduction of new technique, it may be shown in the introduction of BIM. For this, We need to analysis construct-ability of introducing BIM, work field of introducing and operational capability about present domestic construction engineers. Therefore, this study solves the problem of existing construct-ability analysis, and it visualizes the various information and objects for an effective job performance. Furthermore, construct-ability analysis by BIM that can use an intergrated management is theoretically examined and practical field-application priority among conclusions is proposed through a survey targeting on the hand-on worker. Therefore, this study suggests a factor supplying for a business-centric introduction plan and support condition.

This study proposed a Variable Speed Limits(VSL) algorithm to use traffic information based on Cumulative Demand-Capacity Analysis and evaluated its performance. According to the analysis result, the total of delay consisted of 3 separate parts. There was no change in total travel time although the total of delay decreased. These effects was analysed theoretically and then, evaluated through VISSIM, a microscopic simulator. VISSIM simulation results show almost same as those of theoretical analysis. Furthermore in SSAM analysis with VISSIM simulation log, the number of high risk collisions decreased 36.0 %. However, the total delay decrease effect is not real meaning of decrease effect because the drivers' desired speed is same whether the VSL model is operated or not. Nevertheless this VSL model maintains free flow speed for longer and increases the cycle of traffic speed fluctuation. In other words, this is decrease of delay occurrence and scale. The decrease of speed gap between upstream and downstream stabilizes the traffic flow and leads decrease number of high risk collision. In conclusion, we can expect increase of safety through total delay minimization according to this VSL model.

This study was conducted to predict reduction of soybean yield as affected by different densities of Cuscuta pentagona. All data were fitted to Cousens' rectangular hyperbola model to estimate parameters for predicting soybean yield loss. The yield of soybean in the various densities (1 to 48 plants $m^{-2}$) of C. pentagona reduced by 80.3 to 99.7%, respectively. Among yield components, number of pods was the most significantly influenced by weed interferences. The prediction model for soybean yield as affected by weed competition was as follows: Y= 274.6783/(1+4.3522X), $r^2$=0.999 in C. pentagona. Economic threshold levels calculated using cousens' equation was 0.004 plants $m^{-2}$ in C. pentagona.

This study compares the business performances and the socioeconomic and sociopsychological characteristics of franchisees and independent business owners (IBOs). On the basis of extant theoretical arguments and empirical evidences it was expected that franchisees are different from IBOs in these aspects because unlike IBOs they are using franchising as their way of businesses and should satisfy the requirements imposed by franchisors. Analyzed in the current study was a national survey database of 424 franchisees and 5,690 IBOs compiled by the Small Enterprise Development Agency in 2011. As expected, it was found that franchisees were significantly different from IBOs in such traits as financial and managerial capabilities, business experiences, demographic and socio-psychological characteristics, information searching efforts, business performances, and their perceptions of business obstacles. It was also found that the effects of these traits on business performances were quite different between franchisees and IBOs. The findings of the current study provide some meaningful suggestions for government agencies. Given that franchises and IBOs have different traits, their demands for governmental policy should be different, and consequently, it might be argued that government agencies should treat the two groups separately and should increase their efforts to develop appropriate supporting policies for each group. With respect to franchisor's practices for franchisee selection, it is also argued that in order to enhance franchisee performances franchisors need to examine thoroughly the traits of prospect franchisees. This study concludes with discussion of several theoretical and methodological limitations for future research.
