The Korean government has tried to introduce pipeline natural gas from Russia, instead of liquefied natural gas from Middle East Asia since 1990s. While this energy cooperation in North East Asia has been discussed in real politics and academic societies, the previous studies have shown the limits on policy implication because they just suggest necessity and possess the problems of weak theoretical frameworks. Therefore, this study tries to analyze the motivations, conditions, and stages for energy cooperation in this region from the viewpoint of economic integration theory. As a result of analysis, these countries in North East Asia have only one motivation, namely economic interest. On the contrary, they have several conditions including real benefit, complementation in economic structures, and convergence in policy goals. In conclusion, this study suggests that low level cooperation such as preferential trade agreement in the field of natural gas is possible and necessary in North East Asia.

Purpose - The purpose of this study is to analyze Korea's trade relations centered on the Pacific Alliance (PA), a major economic integration in Latin America, and identify its problems and suggest measures that can be taken by the government and corporations to reinforce economic cooperation. Design/methodology/approach - To improve the level of contribution of the study, an empirical analysis is necessary. However, due to limited data access, the study will approach the topic of trade relations between Korea and the PA with various statistics and literature. Findings - First, there is an urgent need for changes in import-export goods between Korea and the PA, as trade is focused on specific items. Second, although foreign direct investment from Korea to the PA is centered in manufacturing and mining industries, there should be different investment strategies by countries and industries. Third, it is necessary to reinforce commercial cooperation. Korea currently has Free Trade Agreements with Chile, Peru, and Columbia, but not with Mexico, the largest trading partner among the PA. Therefore, Korea must take active measures to sign an FTA with Mexico, which has been put on hold. Research implications or Originality - Latin America has the most thriving market when it comes to Free Trade Agreements worldwide. With the official establishment of the Pacific Alliance (PA) in 2012, the economic integration of Latin America faced entirely new circumstances. Reinforcing economic cooperation with the PA is extremely important for Korea in terms of entering and dominating the Latin American market. However, there is still a lack of research on the Pacific Alliance, and corporations that aim to enter the Latin American market face difficulties due to lack of information. By investigating the Pacific Alliance and its prospects and analyzing the trade relations with Korea, this study will provide strategic measures for corporations that wish to enter the Latin American market.

This study was conducted to investigate the responsiveness and its related factors of public health center for novel influenza A (H1N1) epidemic. The data was collected through a web-based survey conducted during February to April 2011. The 182 respondents were team leaders or persons who were responsible for H1N1-related work at public health centers during the H1N1 prevalence. The related factors affecting the responsiveness were different by urban or rural area. In the level of gu (urban) area, cooperation with the public organizations, preparing its own response plan were the significant factors. But, in the level of si or gun (rural) area, cooperation with private organizations (clinic or pharmacy), physical (facilities, equipments, and medicines), and human infrastructures (public health professions, education and knowledge, and motivation) were more important factors. Therefore, how to cope with H1N1 prevalence in the future should be different by local characteristics. As a result, there are several challenges that public health centers should prepare for the further emerging infectious diseases. First, it is needed to make standard manuals which could strengthen education and training in order to respond appropriately, as well as to prepare enough physical infrastructures for the crisis. Next, the public health center should prepare correct media response and cooperation system with public and private organizations.

The aim of this study was to determine the factors contributing to the barrier of dental treatment for special needs patients perceived by the main caregivers of the patients. A questionnaire was developed with three parts: patient-related factors, caregiver-related factors, and factors for treatment barriers. Patient- and caregiver-related factors were analyzed for correlations with the barrier factors. Fisher's exact test and Chi-square test were used at the level of 0.05. A total of 52 caregivers (mean age [SD]=50.2 [11.5] years) for the patients with intellectual and cognitive disabilities (mean age [SD]=38.9 [21.3]) responded to the questionnaires. Oral hygiene status, need for assistance in tooth brushing, and cooperation for tooth brushing were correlated with the level of treatment cooperation of the patients (p<0.05). The above three factors were also correlated with the treatment barrier despite patients presenting oral symptoms (p<0.05). Two thirds of the caregivers felt the treatment cost as severe or a considerable financial burden. For patients, insurance types and need for assistance in tooth brushing, and for caregivers, education levels and financial status were significant factors contributing to financial burden (p<0.05). There were background factors of the patients and their caregivers associated with access to dental treatment for special needs patients. Deficient cooperative skills and financial burdens were the main obstacles to treatment access. Tooth brushing skills and oral hygiene status can be proxy measures to cooperative ability for dental treatment.

This study evaluated college students' virtual academic experience due to COVID-19. Based on Colaizzi's analysis method, data from advanced interviews with 15 students were analyzed. The results were as follows. The participants showed a desire for eye-level learning, frustration on unsatisfactory academic factors, gratefulness for the factors that enhance academic satisfaction, lonely fight with the shortcomings of online lectures, and the factors predicted by COVID-19, and aim to seek balance through health care. Based on the results, the students should be prepared to learn at an appropriate academic level. Second, the change should be sought to increase delivery and concentration in class. Third, students are motivated by the professor's efforts to communicate in class and their sincerity and passion. Fourth, cooperation between professors and learners is needed to develop a sympathetic and supportive classroom atmosphere. Fifth, until the cessation of COVID-19, the principle of virtual education should persist unless there are exceptional circumstances. These results, which suggested specific ways to increase satisfaction with virtual learning lectures, can be used as basic data for establishing effective virtual teaching directions.

According to a lot of investigations, distance perception is influenced by many important cues such as sound pressure level, reflections from the room surface, binaural difference (ITD and ILD), a kind of sound source, and head related transfer functions (HRTF). Two psychoacoustical experiments on auditory distance perception were conducted to examine the effectiveness of the sound pressure level loudness as one of the physical cues in the auditory distance perception under a constant loudspeaker's output level and a constant sound level at the subject's position in the absence of reflections in an anechoic room. Our experimental results showed that the perceived distance of sound image is closer than actual sound source distance with the constant loudspeaker's output level and the constant sound level. Futhermore, the perceived distance of a sound image with constant sound level increased when the actual distance increases up to approximately 2 m while the perceived distance saturated when the sound source distance exceed 2 m. On the other hand, when the condition of loudspeaker's output level was kept constantly, the perceived distance of sound image increased up to around 3m, longer than the conditions of constant sound level at the subject's position. We found that the change in the loudness as a function of distance plays an important role in the auditory distance perception in the absence of reflections..

The purpose of this study is to provide preliminary data to improve the quality of vocational education program by analyzing basic occupational skills and acquired knowledge of vocational college graduates. A total of 236 graduates were sampled to examine their competency importance level - competency performance level, and study differences between competency importance level and contribution level of college education. The paired sample t-test and importance-performance analysis were employed to investigate meaningful differences between competency importance level and Competency performance level in regard to acquired knowledge and basic occupational skills. Meaningful differences were found in 12 areas at significance level of 0.01. According to importance-performance analysis, differences were presented in 4 areas in the first quadrant, 1 in the second quadrant, 4 in the third quadrant, and 3 in the fourth quadrant. In comparison study between competency importance level and college contribution level, the latter was found to be relatively less influential as differences were presented in all of 12 areas at significance level of 0.01. This research will helps to enhance the practicality and effectiveness of education program in vocational college.

The air temperatures of the coast and inland are rising due to an increase in carbon dioxide emissions and abnormal climate phenomena caused by global warming, El Nino, La Nina and so on. The sea levels of the Earth are rising by approximately 2.0 mm per year (global average value) due to the thermal expansion of sea water, melting of glaciers and other causes by global warming. On the other hand, when it comes to designing a hydraulic structure or coastal hydraulic structure, the standard of the design water level is decided by analyzing four largeness tide values and a harmonic constant with the observed tidal water level or simulating numerical model. Therefore, the design tidal water level needs to consider an increasing speed of the seawater level, which corresponds to the design frequency. In the present study, the observed tidal water levels targeting 46 tidal stations operated by the Korea Hydrographic and Oceanographic Administration (KHOA) from the beginning of observations to 2015 per hour were collected. The variation of the monthly and yearly and increasing ratio were performed and divided into 7 seas, such as east and west part of the Southern Sea, south part and middle of the East Sea, south part and middle of the Western Sea, and Jeju Sea. The current study could be used to determine the cause of local seawater rises and reflect the design tidal water level as basic data.

Quick response in the textiles and clothing industry is widely recognized at a strategic concept implemented by information technology to transfer changes in customer needs to the final product as soon as possible. This paper addresses which factors should affect the adoption of quick response systems in Korea. We surveyed 108 companies in the textile and clothing industry by using a questionnaire. We asked whether they adopted QR or not, and measured the usage level of QR-related ITs and the level of both internal and external factors in Likert's scale. We conducted multiple linear regression to analyze the data collected by using SAS. The findings are as follows: The adoption of QR, measured by the usage level of QR-related ITs, is positively affected by internal factors such as the recognition of QR concept and the capability for IT applications and by external factors such as the overall informating level of the industry, the needs for cooperation between organizations, and the leadership as an industry coordinator.
