Objectives: The study investigated health professionals working in the metropolitan area and Jeolla-bukdo, South Korea, from April 30 to May 17, 2017 to understand their views on the issue of including dental hygienists in the scope of medical personnel of South Korea. Methods:A total of 270 surveys were analyzed in this study. The survey consists of 5 questions on general issues; 10 on the awareness of present work of dental hygienist; and 1 on opposition or approval about including dental hygienist in medical personnel. The collected data were analyzed using SPSS for Windows 18.0, as well as frequency analysis, cross analysis and logistic regression analysis. Statistical significance level (${\alpha}$) is 0.05. Results: 1. Broken down by gender, male subjects showed more oppositions against including dental hygienists in the category of medical personnel while female subjects showed more favorable opinions (p<0.05). In terms of academic background, those who had graduated from graduate school or higher showed a higher propensity for opposition while those who had graduated from a 3-year college showed a higher tendency for approval on the idea (p<0.05), In terms of occupational type, health professionals showed more opposing views whereas medical technologists showed more approvals than others (p<0.001). 2. With respect to the awareness of work specialty and proficiency of dental hygienist according to general characteristics, the higher the age, the higher the awareness level was. In terms of the occupational type, medical technologists were found to have higher awareness level than health professionals (p<0.001). 3. With respect to the relationship between general characteristics and view on including dental hygienists in medical personnel, the occupational type of health professional was found to have 6.33 times more oppositions than medical technologists. When the awareness level on proficiency of dental hygienist was low, opposition was 6.52 times more frequent (p<0.05). Conclusions: Based on the findings above, the inclusion of dental hygienists in medical personnel seems necessary in properly establishing the specialty and role of dental hygienist in the dentist medical environment of the country in order to enhance national oral health related preventive dental service and expand the demand. To this end, it is necessary to provide nationwide promotion, work to change the awareness of health professionals in other occupational types, and facilitate public promotion for legal ground establishment.

본 연구는 한국노동패널을 사용하여 2002~2005년 3년 동안 직장이직률 추세와 이에 영향을 주는 여러 요인들 가운데 노동조합의 역할을 중심으로 실증분석하였다. 기초통계량에 있어서는 노동조합에 가입된 근로자의 직장 유지율이 노조에 가입되어 있지 않은 근로자보다 평균 28.3%포인트 높게 나타났으나, 직장이직에 영향을 미치는 개인의 관측되는 변수를 통제한 결과에서는 노동조합이 직장유지율을 11~13%포인트 증가시키는 것으로 추정되었다. 노동조합이 근로자의 고용안정에 미치는 효과를 세부적으로 살펴보기 위하여 Fairlie(2003)가 개발한 비선형분해 방법을 사용하여 분석하였다. 비선형분해(Non-linear decomposition) 방법을 사용하여 노조-비노조 간 직장이 직률의 차이를 근로자의 관측되는 변수에 의해 설명되는 부분과 설명되지 못하는 부분으로 나누어 살펴볼 때 설명되는 부분의 기여도가 67~74%로서 추정되고 설명되지 못하는 부분이 나머지 26~33%를 차지함을 알 수 있다. 이는 노동조합이 조합원들의 고용안정에 기여한 부분 외에도 노조에 가입된 근로자의 직장이직 성향이 노조에 가입되지 않거나 노조가 조직되어 있지 않은 사업장에 종사하는 근로자보다 평균적으로 낮음을 시사한다. 실증분석 결과는 노동조합의 고용안정 효과는 최대 7~9%포인트 경계 안에서 한정됨을 시사한다. 노동조합의 고용안정에 미치는 효과가 이처럼 작은 원인은 기업별 단체교섭구조, 외환위기 이후 기업경쟁의 심화, 기업규모별 노동시장 분절화 등 다양한 원인을 추론해 볼 수 있을 것이다.

Rapid progress of information technology and widespread use of the personal computers have brought various conveniences in our life. But this also provoked a series of problems such as hacking, malicious programs, illegal exposure of personal information etc. Information security threats are becoming more and more serious due to enhanced connectivity of information systems. Nevertheless, users are not much aware of the severity of the problems. Using appropriate password is supposed to bring out security effects such as preventing misuses and banning illegal users. The purpose of this research is to empirically analyze a research model which includes a series of factors influencing the effectiveness of passwords. The research model incorporates the concept of risk based on information systems risk analysis framework as the core element affecting the selection of passwords by users. The perceived risk is a main factor that influences user's attitude on password security, security awareness, and intention of security behavior. To validate the research model this study relied on questionnaire survey targeted on evening class MBA students. The data was analyzed by AMOS 7.0 which is one of popular tools based on covariance-based structural equation modeling. According to the results of this study, while threat is not related to the risk, information assets and vulnerability are related to the user's awareness of risk. The relationships between the risk, users security awareness, password selection and security effectiveness are all significant. Password exposure may lead to intrusion by hackers, data exposure and destruction. The insignificant relationship between security threat and perceived risk can be explained by user's indetermination of risk exposed due to weak passwords. In other words, information systems users do not consider password exposure as a severe security threat as well as indirect loss caused by inappropriate password. Another plausible explanation is that severity of threat perceived by users may be influenced by individual difference of risk propensity. This study confirms that security vulnerability is positively related to security risk which in turn increases risk of information loss. As the security risk increases so does user's security awareness. Security policies also have positive impact on security awareness. Higher security awareness leads to selection of safer passwords. If users are aware of responsibility of security problems and how to respond to password exposure and to solve security problems of computers, users choose better passwords. All these antecedents influence the effectiveness of passwords. Several implications can be derived from this study. First, this study empirically investigated the effect of user's security awareness on security effectiveness from a point of view based on good password selection practice. Second, information security risk analysis framework is used as a core element of the research model in this study. Risk analysis framework has been used very widely in practice, but very few studies incorporated the framework in the research model and empirically investigated. Third, the research model proposed in this study also focuses on impact of security awareness of information systems users on effectiveness of password from cognitive aspect of information systems users.

본 연구는 100여일 앞으로 다가온 대통령 선거를 즈음하여 발생할 수 있는 정치지도층에 대한 요인테러를 사전 예방하고자 기존 국내 요인 테러를 분석하고 대응 방안을 제시 하였다. 정치 테러발생 원인의 대다수는 이념이나 사회 갈등이 최고조에 달할 때 주로 정치적 소외계층에 의해 이뤄진다. 일반적인 원인으로는 공격하고자 하는 대상이 싫다거나 내가 지지하는 당이나 정부가 불리하고 패하는 것이 참을 수 없을 때 주로 발생한다. 21세기 정치테러가 기존의 불특정 다수와 신무기 폭발물 등을 사용하여 공격하는 빈도 보다는 사회 부적응자들의 불만 표출이나 사회적 갈등에 의해 자행되는 경우가 많다는 것이다. 이는 심화된 편 가르기와 무너진 법질서로 인해 사회 양극화가 심화한 데다 우리 사회가 정치적 타협에 익숙지 않다 보니 개인적 불만이 과격한 수단으로 나왔기 때문으로 풀이 된다. 절대적인 신변보호와 함께 다수의 유권자에게 다가가야 하는 정치활동에 최상의 결과를 거두기 위해서는 신변안전에 대한 경호임무는 필수 요건이다. 따라서 정치활동에 있어완벽한 신변보호를 위해 상황별, 장소별, 지역별 등 운집 되어지는 성격에 따라 적절한 경호기법으로 전문적인 경호활동을 해야 할 것이다.

This research was carried out as a basic survey to provide more effective and improved food service for the soliders of the Armed Forces who are serving to defend the Republic of Korea subjects were selected randomly who were serving in the army for a short-term. Following is the result of a survey regarding the situation of their meals, dietary life, and their food preference of 190 kinds of foodstuffs. As a result of surveying the dietary life of the soldiers, they indicated that there was dissatisfaction in the current Food Service because it lacked tasted and the same kind of meals were being served too frequently with regard to this, many subjects expressed that they were eating out because of the quality of they get from the regular meal service the meals, that is they were eating in restaurants to resolve their dissatisfaction over the quality of the meals. It was also surveyed that in the current meals there is a need to diversify ways in preparing food, increase the number of dishes, and improve the tasts of the food by using improved cooking method. It seemed that the soldiers were satisfied in the quantitative level of the current food service but that there is a need to improve the meals in quality. Following is the result of a survey on the preference of foodstuffs. In case of rice as the stationary food, mixture of five-grain plain white cooked rice showed a higher propensity compared to plain whte boiled rice. This shows that soliders prefer various cereals in their rice. Soliders liked soup made from meat better than vegetable soup or soup made from fish. Especially there was a high performance for beef soup. Soliders liked One-dish meals such as fried rice or boiled rice with asserted mixtures, noodled, and dumplings on the whole-soliders generally liked vegetables and they liked uncooked vegetables better than cooked vegetables. Generally everyone liked beverages and there was a high preference for dessert. Among various rice cakes soliders liked songpyon(rice cake steamed on a layer of pine needles) and injolmi (cake made from glutinous rice). On the other hand, soliders did not like food prepared with fish, biscuits and candy very much. In the way of preparing food, soliders liked food that were fried in deep far rather than food cooked in water. Also they liked pot stem better than soup. As examined in the survey, those surveyed wanted improvement in the quality and diversity of the food rather than increase the number of food and quality. Therefore there is a need for diversified supply and demand of quality of meal service.

This study was conducted to gather the baseline data on realities of experimental-practice and opinions toward spot-practice, and to examine how to cope with the problems raised at the Department of Food and Nutrition of Junior Technical College in Korea. Questionnaires were gathered from 42 chairmans of the Department of Food and Nutrition and 140 Present dieticians worked in Seoul, Bucheon am Seongnam area. The results are as follows, First, as a whole, each college had 2~3 experimental laboratory (Lab), in which Cooking Science Lab. Chemistry Lab and Microbiology Lab were occurred at higher frequency as Lab's name. Second, the numbers per experimental-practice class were more than 40 at most colleges. 85% of Present dieticians have answered to feel too much numbers per the class during their college days, whereas professors' opinions toward the numbers per class were suitable at 20~30 persons per class. Third, professors' opinion toward the adquate ratio of the theory subject classes to experimental subject classes was suitable at 60 : 40. Dieticians answered to take the theory subject classes partly or mostly on behalf of the experimental-practice classes. Fourth, the main reasons which inhibited normal experimental-practice class were the class for emphasis on examination, the shortage of experiment budget, the excess of class members, the shortage of experimental Lab Also, this results showed same propensity to present dieticians' opinion toward the same question above. Fifth, among the experimenta1-practice subjects established at the Department of Food and Nutrition, Diet Therapy Lab was highest frequency class emphasized on theory followed by Nutrition Counselling Lab, Food Processing and Storage Lab, Food Hygiene Lab and Food Microbiology Lab in that order. Here, Basic Chemistry Lab, Biochemistry Lab, Food Microbiology Lab were pointed as subjects far from the present task of dieticians. Sixth, Department of Food and Nutrition, as a whole, has conferred with spot-practice arrangement About 50% (all who want to join spot-practice) of second year students took part in spot-practice. In the other way, all colleges except for 2 colleges didn't give the credit for the spot-practice system. Seventh, according to the on analysis on spot-practice places, manufacturing company was at highest frequcney followed by hospitals, elementary school having group feeding system in that order. Especially, 16.7% (5 colleges) of the total colleges sent the students to the research institute related to food industry for spot-practice experience. Eighth, Professors' opinions toward the spot-practice time and period were preferable on summer vacation of second year and for 1~2 weeks, respectively. On the contrary, 74 dieticians answered to the adquate period as for 4 weeks. Ninth, 86 dieticians of the total 140 answered to complete the spot-practice during their college days, which helps the present task of them. Lacks of spot-practice program, Lacks of comprehension of upper personals and lacks of group feeding equipments ranks higher as difficulties in spot-practice management.

Background: From January 2018, a policy was applied to differentially apply the co-payment for medical expenses of 15,000 won or more from 30% to 10%-30% for each medical fee. This policy lowers the burden on the medical use of the elderly, and it is necessary to analyze the effect of the policy by confirming changes in medical use and supply behavior after 2 years. Methods: The National Health Insurance Service's national medical use database was used. As for the analysis method, first, the medical use and medical supply behavior change over the age of 65 years were confirmed, and second, in order to check the net effect of the policy, the 66-year-old as the experimental group and the 63-year-old as the control group were selected as the control group. The propensity score matching was performed using the variables of age, living alone, income quartile, residence, disability, chronic disease, and co-morbid disease scores, and then it was analyzed using the difference in difference analysis method. Results: The share of the number of treatments under 15,000 won decreased from 37.0% in 2017 to 20.2% in 2018, while the share of the number of treatments under 15,001-20,000 won increased from 8.0% to 22.7%. It was confirmed that the reason for the increase in the cost of treatment per treatment was the result of the increase in the amount of physical therapy and examination. As a result of the policy effect, the burden of co-payment per person was reduced, and as a result, the number of hospital visits per person and the total medical cost per person increased. Conclusion: The self-pay rate differential policy reduced the burden of medical expenses for the elderly and confirmed the increase in medical use. However, the interpretation of the increase in medical use was not able to distinguish whether the unsatisfactory medical care was satisfied or the inducement demand. Efficient allocation of resources is a more important point in the future when the super-aged society is in front. It is necessary to prepare a plan to induce rational medical use within a range that does not impair the medical accessibility of the elderly.

Computational Science and Engineering is a convergence study that understands and solves complex problems such as science, engineering, and social phenomena through modeling using computing resources. Computational science and engineering combines algorithms, computational and informatics, and infrastructure. The importance of computational science is increasing with the improvement of computer performance and the development of large data processing technology. In Korea, Korea Institute of Science and Technology Information (KISTI) has been developing national computational science engineering software and utilization technology by combining basic science and computing technology through EDISON project. The EDISON project builds an open EDISON platform and integrates and services information systems in seven areas of computational science and engineering (computational thermal fluids, nanophysics, computational chemistry, structural dynamics, computational design, and computational medicine). Using this, we have established a web-based curriculum to lay the groundwork for fostering scientific talent and commercializing computational science and engineering software. The purpose of this study is to derive the quality characteristic factors of computational science platform and to empirically examine the effect on user satisfaction. This paper examines how the quality characteristics of information systems, the computational science engineering platform, affect the user satisfaction by modifying the research questions according to the propensity of the computational science platform by referring to the success factors of DeLone and McLean's information system. Based on the results of this study, we will suggest strategic implications for platform improvement by searching the priority of quality characteristics of computational science platform.
