Lane Designation is defined as reasonable road management to ensure the road safety and enhance road efficiency. While the lane designation system was abolished in 1999, it was redefined because of the increasing number of large vehicles in the passing lane, violent on driving and traffic accidents in 2000. The needs of improvement on operating the lane designation has been increasing more in recent due to the low ratio of compliance with the system and difficulties to keep the right lane due to need of turning and demand of widening of designates lane for two-wheeled vehicles and truck. In this study, we presented the improvement plan through the question survey, simulation analysis, safety evaluation. It found a problem that the low-speed vehicle is to use the upper level roadway, difficulties of supervision, the imbalance in the lane use, imbalance traffic and does not match the international standards. This study suggested five different alternatives through the survey. micro simulation has used in order to examine each alternative by management effectiveness and feasibility. It analyzed the traffic speed, efficiency, traffic balance of alternatives. Also, safety evaluation conducted in terms of the range of field-of-view to ensure the easiness of field of view by various configurational difference between the vehicles. By the analysis results of such indicators, This study presents proposals for improvement in operating designated lane that low-speed-big-sized vehicles keep to the right lane, and high-speed-small sized vehicles keep to the left lane.

The purpose of this study is to examine whether any correlation exists between the dental health capacity and preferred foods of Korean senior citizens over the age of 65 years. The 5th Korean National Health and Nutrition Survey were used. Tissue health index (T-health), Sound teeth (ST), Functioning teeth index (FS-T), Present teeth (PT), and Missing teeth (MT) were used as variables to assess the dental health capacity of the elderly. Preferred foods of the elderly included 63 foods that were categorized as cereals, pulses and roots, meat and poultry, fish, vegetables, sea algae, fruits, milk and dairy products, cream and sugar, and other foods. For data analysis, the weighted average was taken into consideration to generate planning files, and then complex sample analysis were conducted. For statistical analysis, frequency analysis, t-test, one-way ANOVA, and compound specimen linear regression analysis were conducted. T-health score was significantly high in the group with high preference for cereals, fruits, and other foods. In terms of age and economic status, 65~69 years, 70~74 years, and mid to low range in the income ranges scored high in T-health. ST score was significant in the group that preferred cereals, other foods; the corresponding demographic profiles represent 65~69 years, 70~74 years, and the mid-range income communities. FS-T was significant in relation with a preference for fruits, creams and sugars, other foods; the scores were also high for 65~69 years, 70~74 years, and mid-low to low income groups. PT and MT were significant in the group that preferred cereals and fruits; the same applied for 65~69 years, 70~74 years, and mid-low to low income individuals (p<0.05). Food preferences seemed to vary depending on the dental health state of the elderly, and the dental health state of the elderly may act as a risk factor for nutritional imbalance.

Background: Potassium, the most common cation in the intracellular space, plays a critical role in our physiology. Potassium imbalance may cause life-threatening problems, ranging from general weakness to cardiac arrest due to ventricular fibrillation. For emergency physicians, detection of such derangement within a short period of time is of critical importance. In this study, we wanted to determine whether analysis of whole blood samples can be used as a screening tool for potassium imbalance by comparative analysis of whole blood and serum samples. Methods: Two samples were drawn from 227 patients. The whole blood sample was taken from the radial artery and contained in a commercially available arterial blood collection syringe with a lithium-heparin coating. The serum sample was contained in a commercially available vacuum bottle in a non-additive silicone coated tube and transported to the laboratory. The study population was divided into three groups, patients with normal whole blood potassium, patients with decreased whole blood potassium, and patients with elevated whole blood potassium. Potassium levels for each group were coupled with serum potassium levels and compared. Results: No significant difference in potassium values was observed between whole blood and serum samples (P<0.05). Strong associations were observed among the three groups (normal range, hypokalemia, and hyperkalemia group). Compared to the normal group (r=0.851), the hyperkalemia group showed a stronger association between variables (r=0.897), and the hypokalemia group showed a weaker association (r=0.760). Their correlation coefficients were highly significant (P<0.05). Conclusion: Our study illustrates that point-of-care testing using whole blood with whole blood can be a reliable screening tool when treating patients with suspicious potassium abnormality, especially in hyperkalemia patients.

The importance of selection methods of secondary school teachers have gathered attention due to their enormous influence on the pre-service education programs. However, scholars and practitioners are skeptical about the effectiveness of the measures, especially under the condition of teacher oversupply found in South Korea and China. Based on this problem statement, this study seeks to compare the secondary teacher employment methods of the two countries to better understand the situations as well as to draw implications for improvement. We reach the following conclusions through comparative analyses. First, the reforms of the teacher employment system in both countries have been triggered by the quantitative supply concerns not by the qualitative concerns. Second, both countries require teaching license as a precondition of employment, while their quality assurance measures for the license reveal critical limitations. Third, both countries have attempted to improve selection methods; nevertheless, oversupply of prospective teachers makes objectivity and fairness more important than the appropriateness. Based on the conclusions, policy implications focusing on the quality-oriented approach are suggested in order to employ effective secondary teachers who can contribute to the quality improvement of school education.

Using the United Nations Convention on the Rights of the Child(UNCRC) as a frame of reference, this study examined South and North Korean children's rights as reported in the UNCRC and the pattern of changes in the reports depending on the period in which the reports were written. For this purpose, we reviewed Article 1 of the Convention to see what age range the South and North Korean governments, respectively, specify to define a child. We also analyzed the method and attitude of how each Korean government acknowledges the rights of children in the four general principles of the Convention("non-discrimination", "the best interests of the child", "the right to life, survival, and development" and "respect for the views of the child"). The results showed that there was asymmetric content between South and North Korea in the four general principles of the Convention. Both South and North Korea lack a sense of respect for the views of children. There were also differences in the rights of children depending on the distinct characteristics of each Korea. In South Korea, it is important to guarantee the rights of multicultural children and provide a plan for child safety. On the other hand, North Korea has emphasized that they provide the necessities of life and free education to children. Both Koreas have continuously submitted their reports and showed improvement in understanding the rights of children in each report. We conclude that it is essential for South and North Korea to build common ground in their respective contents on children and to establish a foundation of normative standards in the path to prepare for reunification. Moreover, we also conclude that South and North Korea should work collaboratively to reach mutual consent to achieve these goals.

The purpose of this study is to examine work-life balance by analyzing time schedules of married couple. The 2014 Korea Time Use Survey dataset was used for the analysis. Finally, 6,262 time diaries of 3,131 households were included in the analysis. The study used sequence analysis in particular, by applying the Lesnard(2014)'s dynamic hamming matching (DHM) method, which is useful for the time diary analysis where timing is a key factor. This study explored daily schedules of each man and woman according to 9 types of couple-combined work-schedules, which had been already derived by cluster analysis. The daily schedules were identified according to the activities divided as labor, housework, sleep, self-management, active leisure, passive leisure, and others. Here, time allocation was analyzed through various graphs showing average time amount and modal states by time period. Based on the analysis, it summarized that "long working hours as a main factor of work-life imbalance", "gender inequality of time use", "non-standard hours work impairing quality of life and "poverty of leisure time"as characteristics of work-life imbalance. Finally this study discussed the social policy implications to support work-life balance.

Nowadays, soft power is playing a more important role in international communication and cooperation, and as cultural exchange in regional cooperation is deeply influenced by national soft powers, the development is usually unbalanced. Bangladesh, China, India and Myanmar are adjacent to each other with a long history of intercourse. In the year 2013, initiation of constructing Bangladesh-China-India-Myanmar Economic Corridor advocated by China and India was responded positively by Bangladesh and Myanmar. Since then, the world has witnessed an increasing connection of these four countries. Being the critical bond connecting the southwestern areas of China and Bangladesh, India as well as Myanmar, Bangladesh-China-India-Myanmar Economic Corridor is characterized by multiple regional cultures along with frequent connections in cultural products and activities. However, cultural exchange now is dominated by imbalanced development due to potent soft power of China and India that these two countries export more cultural products to the rest, which has an impact in many fields of Bangladesh and Myanmar. Priority should be given to coordinated development in cultural exchange regarding the construction of Bangladesh-China-India-Myanmar Economic Corridor. Only by developing a sustainable development mechanism for cultural exchange, to coordinate the influences of soft powers of these four countries, then a fine complexion of "all flowers are in bloom" can be created, returning to five original intention of the construction of this economic corridor: "Policy Communication" and "Strength People-to-people Ties", etc.

Thanks to various efforts to reduce disasters by the government and the Health and Safety Authority, disasters across industries and the construction industry show their reduction trend. However, the falling disasters in the construction industry have not decreased and increased on the contrary. Especially falling disaster caused by Hanging Scaffolding is the most critical disaster which shows low occurrence frequency but is directly connected to death of worker. The working environment for Hanging Scaffolding is poor in domestic construction site. In particular, the Hanging Scaffolding workers in small construction sites are not on the safety control and management by anyone for their works. They are driven to unsafe working condition with mostly uncertified facilities which are made by themselves. Therefore, this study is focused on searching falling disaster factors from the 242 disaster cases caused by Hanging Scaffolding Work in 15 years presented by KOSHA, and trying to provide suggestions for improvement. The improvement of the method of work requires facility improvement and work due to high accident rate caused by unsafe behavior. Analysis of the case of a disaster occurring over the past 15 years shows that no disaster occurred due to problems in the order of operations presented by KOSHA. However, it was found that many accidents resulted from death caused by safety belts not being installed or attached to ropes using safety belts without following the order of work. The most important aspect of improving the work method was the installation and wearing of lifeboats and safety belts.
