The goal of the entrance examination models is to promote promising and potential students who are suitable for post-secondary education purposes. Recently, a promotion system based on the admissions supervisors has been the major role for the promotion of students. Various statistical models and methods should be applied for the better and reasonable promotion of promising Korean and international students. In this study, we applied the proper methods in statistical methodologies and show the meaningful results on the performance evaluation of the several entrance examination models for a university in Seoul, Korea.

Due to a decrease in the number of college prep students which was triggered by the low birth rate since 1990, it is predicted, beginning 2016, that the entrance quota for colleges will exceed the number of applicants for college admissions. This serious imbalance between supply and demand raises serious problems for the regional universities, many of which have already been struggling to recruit new students and even considered closing down the schools. In an effort to securing best high school students, many of the schools have been developing various unique and specialized selectional processes for the applicants. In this research, through a statistical analysis of special admission processes for vocational high school students who were admitted to a regional state-run university (University A), I tried to find a way to effectively deal with the student management. Statistically analyzing these first-year students' enrollment and their adjustment processes as well as the departmental relationships and gender differences, I tried to find some better ways to secure good applicants. It is expected that this study will not only be utilized as guide to adopt a way to bypass the enrollment quota in order to secure talented students but also be served as a reference that will help the students adapt themselves to school life until they graduate. It is also expected that this study will be expanded in such a way as to compare it with other models and even develop a new type of college entrance system that would fit future college admission policies.

Objectives: This study was conducted to measure the level of radon in the air at a highway tunnel construction site in a gneiss area using the New Austrian Tunneling Method (NATM) and to evaluate exposure levels by occupation. Methods: Radon concentrations in the air were measured using E-PERM at points 300 m, 600 m, and 900 m from the tunnel entrance during the excavation and waterproofing work inside the tunnel. In addition, radon concentrations were measured during external excavation to compare with the inside of the tunnel. Personal exposure levels for major occupations including tunnel workers, construction equipment operators, waterproofers, shotcrete workers, and safety and health managers who participated in the construction were estimated using radon concentration measured in the work process area and working hours by occupation. Results: As a result of a total of 77 radon measurements, the geometric mean (GM) concentration was 71.1 Bq/m³, and the maximum concentration was 127.3 Bq/m³, which was below the indoor air quality criteria. Radon concentration by process decreased in the order of the tunnel excavation process (GM= Bq/m³, GSD=1.2), waterproofing process (GM=73.35 Bq/m³, GSD=1.2), and outside excavating process (GM=45.28 Bq/m³, GSD=1.2). Processes inside the tunnel were significantly higher than outside excavating processes (p<0.05). There was no statistically significant difference in radon concentration measured inside by distance from the tunnel entrance, but the innermost point of the tunnel, 900 m (GM=79.24 Bq/m³, GSD=1.27), measured the highest. Conclusions: The occupation with the highest individual exposure to radon was tunnel worker (64.16 Bq/m³), followed by construction equipment driver (64.04 Bq/m³) and waterproofer (63.13 Bq/m³).

The definition of the national security is that the lives of its people and the property of the country must be kept from the enemies. The people in the country must have the awareness of national security in their mind, and the fate of the country relies on the security awareness of the people. Most of college students are to have their own goals trying to fulfil in their life. If the national security is not guaranteed, it will not be possible to achieve their dreams and goals. Currently, most of college students have been trained only for passing college entrance exams in their growth processes, and some of them are confused with political, social, and cultural identity. College students are spending most of time on the preparation for getting employment, so they are indifferent to the national security of their country. After the seminar for college student's unification and security, we will survey how much they could be changed and propose the guidelines for college student's security awareness.

The purpose of this study was to examine school-level science elective-centered curriculum operation and teachers' perception of their instruction of elective-centered science courses. Data were collected from 12 science teachers in 12 high schools in the metropolitan Seoul area through semi-constructed interviews. The results showed that students were supposed to select science subjects under insufficient guidance and their choices on subject were also restricted due to school administrative processes such as teacher's instructional time allocation. Participants were well-perceived different group characteristics among humanities course and science course students toward science learning, still, they felt difficulties in valuing students' variety by differentiating contents and teaching methodologies due to school assessment system and workload of extra instructional material preparation. Influenced by the current college entrance examination system, low motivation for humanities course students and students' choice concentrated in chemistry and life science for science course students, were pointed out as main problems. As a way to improve science education for 11th - 12th graders, developing customized science curriculum for humanities course and science course respectively, changing of entrance system into increasing importance of science for students who will major in non-science fields, and designations of essential prerequisite science subject for students who will major in engineering & science fields, were suggested.

This study aims to investigate how secondary mathematics teachers use mathematics curriculum materials such as textbooks and teachers' guide in planning lessons and for their learning. 24 in-service mathematics teachers participated in surveys and two among them were interviewed. The findings from the data analysis suggest that: a) the teachers actively engaged in decision-making processes of the transition from written curriculum to intended curriculum; and b) the teachers showed a tendency of consulting to the ideas suggested in the curriculum materials for selecting objectives and contents for lessons and the what to assess, not ideas for selecting teaching methods and how to assess. Also, various factors such as students' achievement, participation, interest in mathematics, family environment, and college entrance were identified to influence the teachers' use of the curriculum materials.

The global process of transition from industrial to information society, as well as socio-economic changes taking place in Ukraine, require significant changes in many areas of state activity. It is especially connected with the reforms in the sphere of education. Today, national programs provide for the development of education on the basis of new progressive concepts, the introduction of the educational process of new pedagogical technologies and scientific achievements, the creation of a new system of information education, entrance of Ukaine into the transcontinental computer information system. Information technologies are qualitatively changing the key resources of development: this is no longer a space with fixed production, but primarily mobile finance and intelligence. They have a direct impact on the formation of personal growth, professional content and self-organization, emotional and psychological maturity and consciousness, and so on. One of the main factors in ensuring the stability and social education of the country's citizens is the culture of security, the formation and development of which is an urgent problem today. Comprehensive and systematic development of security culture will significantly increase the readiness of the population, the level of environmental, labor and patriotic education, reduce human losses, material damage from emergencies. Ecological education can be carried out more successfully only gradually and in accordance with the socio-psychological periods of one's development: kindergarten - school - college - university. The creation of such a system of environmental education should be enshrined as the basis of state environmental policy as a constitutional norm with the usage of information technology. Graduates of universities, who are the future of our country, after mastering the skills of basic environmental education must have a high level of environmental culture, which is, in turn, part of general human culture, and investigate environmental issues from the standpoint of their profession. It is known that with the help of environmental education the collective intelligence of society is formed, which can predict human activities and processes occurring in nature, and in some way to help with the elimination of crises. It is through environmental education that another system of human values is being formed, which places great emphasis on intangible wealth and solidarity, and great responsibility of humanity for the ecological state of the native country; provides a higher standard of living as a result of sustainable development, through the introduction of information technology in this system. To improve the quality of life, we need better knowledge, which must be implemented through information technology at the international level.

This research aims to provide basic materials for assisting DNR patient cares by understanding ICU nurses' awareness and ethical attitude regarding DNR. A total of 154 results were analyzed which were collected from Aug. 1st to Sep. 5th in 2014 by surveying nurses working in ICU (from 1 advanced general hospital in G metropolitan city and other general hospitals of more than 700 beds in Cheolla provinces). (1) For the decision attitudes of DNR, there were both consent and objection. Consent for the patient's opinion of rejecting further treatment and life extension despite of bad prognosis. And objection for no conducting DNR in the case of the patient's wish, treatment requested by the guardian, and CPR for the patient who has no chance. (2) Objection for artificial respirator and other treatment requested by the patient's family and the entrance of guardians into ICU. Consent for the passive use of artificial respirator by the doctor and the decrease of basic care to stabilize patients physically and mentally. No specific opinion for treatment not following aseptic techniques. Objection for frequent reports to primary care physician requested by the family. (3) Acknowledging less interest by the doctor, while supporting the health care team in the case of the guardian's complaint, objection for the DNR decision mede by the primary care physician. Objection for the DNR decision by the guideline. Objection or neutrality for straightforward explanation to the patient of bad prognosis. Objection for straightforward explanation of the patient's status (even near to death) to the patient him/herself or the guardian. In conclusion, the subject of DNR is the patient and the patient's opinion should be fully reflected. The conflict arising from the scope of medical practice and decision processes should be minimized. The standard and guideline for DNR decision is required for the ethical decision making for the patient along with agreements based on full explanations.
