Background: There is an opinion that improper postures of the head and cervical spine are associated with temporomandibular joint (TMJ) disorders (TMDs). Objects: The aim of this study was to investigate the proportions among the cervical kyphotic angle, physical symptoms including the pain intensity level of the TMJ, and severity of TMD disability in patients diagnosed with TMD. Methods: Sixty-two subjects participated in the study. The evaluation tools included measurements of the cervical kyphotic angle based on the Ishihara index, pressure pain threshold (PPT) on the TMJ, maximal mouth opening (MMO) without pain, current pain intensity level of the TMJ measured using the Quadruple Visual Analogue Scale (QVAS), Korean TMD (KTMD) disability index, KTMD Symptom Frequency/Intensity Scales (SFS/SIS), and Korean Headache Impact Test-6. Correlation analysis was conducted to investigate the correlations between the cervical kyphotic angle and parameters related to TMJ symptoms. Results: Variables that were significantly correlated with the cervical kyphotic angle were the PPT around the TMJ (r = 0.259, p < 0.05), current pain intensity level of the TMJ based on the QVAS (r = -0.601, p< 0.01), and usual pain intensity level based on the SIS (r = -0.379, p < 0.01). The level of TMD functional disability was significantly correlated with the degree of headache (r = 0.551, p < 0.01), level of PPT of the TMJ (r = -0.383, p < 0.01), pain-free MMO (r = -0.515, p < 0.01), pain intensity level of the TMJ based on the QVAS (r = 0.393, p < 0.01), TMD symptom frequency (r = 0.739, p < 0.01), usual pain intensity of the TMJ (r = 0.624, p < 0.01), and most severe pain intensity of the TMJ (r = 0.757, p < 0.01). Conclusion: There is a positive correlation between the cervical kyphotic angle and PPT and a negative correlation between the current and usual pain intensity levels of the TMJ. The cervical kyphotic angle was a predictor of the pain level, tenderness threshold, and intensity of pain in the TMJ.

Since Korea and Japan established diplomatic relationship, Relationship between Korea and Japan has not been easygoing. There are two most explosive, and noticeable ones among topics which have affected the relationship ; Dokdo and Historical Distortion. Without these issues, relationship between two countries will take a turn for the better. However, unfortunately, it seems that it is almost never going to happen. There is the Japanese conservative right-wing who has an influence on those two issues. The right-wing takes regard getting negative view or finding out dark past as an action from Self-torture view of history, and tries to dilute the Japanese sense of guilt on past invasions to neighbor countries. Moreover, to become a "normal country", they are trying to revise Constitution of the Japan so that Japan can possess the military and re-arm, dispatch troops abroad, and get the right to break the war. In other words, they expect Japan to become a powerful nation with great influence on Asia and world, as the period in which Japan conquered Korean peninsula, China, and South-Eastern nations. Japan still harbours secret romanticism for bygone days of imperialist glory. That is why neighbors want to never make the painful history happen again. In order to deal with this effort, most of all, it is required to assert better argument with a careful, thorough analysis on Japanese opinion about Dokdo. There might be a hidden card which can be accepted in the international society considering Japanese persistent effort to make Dokdo disputed area, and that is why we have to know that it is. In addition, it is needed to secure a high-quality professional manpower because the issues of Dokdo and Historical Distortion are primarily the matter of logic and references. The professional manpower should have open-minded to break down walls of their own majors. We have to introduce our achievements and stances to the international society vigorously. As a definite way to solve these problems, we have to develop national power. We have to possess naval forces and coast guard to protect our territory and Koreans overseas. There are not many options Korea can do to Japan, except protesting denunciation, and pressing a joint efforts. Most of the suggestions stated before are what have to be conducted domestically. It is a miserable condition, because two problems are Japanese domestic issues, but they become international issues and we have to seek a solution for ourselves.

Public opinion has dramatically shifted from positive to negative in Korea society especially since the IMF crisis. Such terms as 'aristocratic union', 'collectivism', 'damages on public interest' became a kind of conventional wisdom. Undoubtedly, media's representation has much to do with such a tantamount difference. This study thus attempts to understand the mechanism by analyzing media discourse related to labor strikes. For this purpose, this paper made a choice three cases including doctor-pharmacist dispute, general strike by truckers' solidarity, and Ssangyong Motor's strike. Total 217 editorial pieces of , and conceived to be a representative newspaper of ideological stance were analyzed. Research showed that while paying particular attention to demoralizing labor strikes, shed positive light on such disputes by articulating fundamental causes hampered by pro-capital policies along with anti-labor law enforcement. The believed to be relatively a neutral one showed ambivalent attitudes toward those cases. More favorable and inclusive reporting were found in accordance with policy shifts as well. Media's selective partisanship for the sake of private interests is firmly believed to downgrading credibility on Korean journalism. Also is fair, balanced and less biased reporting over socal disputes a vital part in crystallizing social consensus. In this consideration, the authors hoped this study to provide an opportunity to contemplate on what would be desirable journalistic values in modern democracy.

The purpose of this study was to explore the direction of application and quality management plan of science curriculum of elementary and middle school according to the 2009 revised curriculum. In order to do this, nationwide survey was administered. The subject was 126 elementary school teachers and 88 middle school science teachers. It was founded that teachers had negative opinion on the introduction of the grade cluster system. They considered that it was appropriate to link the contents of Science subject with Practical Arts(Technology Home Economics) subject by similar topic. Science classes were implemented without changing the number of class hours in most schools. They recognized the necessity of differentiated instruction in science classes, but they seldom applied the differentiated instruction. And they suggested that the teaching-learning materials, evaluation materials and contents be provided to apply the STEAM. This study designates the following strategic supports for the effective implementation of 2009 revised science curriculum; 1) the science teachers training program to provide useful information for understanding and teaching the 2009 revised science curriculum, 2) the teachers' community in the school, 3) the development and provision of the feasible STEAM plans.

The social impact of science and technology is increasing, the meaning of technology assessment is not small in modern society, Specially, the technology assesment(TA) has been institutionalized and performed by Korean administration and its official results has reflected directly in the S&T policy. Therefore, the technology assesment is a device that prepare the negative effects of S&T and the social controversy in advance. To select the target technology of technology assessment will be done carefully in various perspective and concerned with the characteristics of technology assessment emphasizing social assessment, the institutional system of selecting one technology in each year and the contents and methods of evaluation that are determined in accordance with technology characteristics. However, the method of selecting target technology in TA is mostly peformed by qualitative discussion and vote rather than by reflecting various opinion and understanding TA until now. In this paper, we developed the indicator has to be considered to select target technology for TA by using factor analysis. Developed indicator is consist of five factor, such as the need for social consensus and the size of social/cultural impact etc., and we weight each factor by using Analytic Hierarchy Process(AHP). Futhermore, we show the example how to applicate directly these indicator and weights to select target technology and suggest institutional application in TA. Though using developed indicator in this paper, we expect to select appropriate technology for institutional TA and the application of TA results in society and public policy can be strengthened.

Because consumers tend to have negative opinion about a company that neglects social issues like poverty or pollution while it focuses on its own profit, a lot of companies have invested their resources in Corporate Social Responsibility(CSR). CSR has merits of image improving and profit gaining, on the other hand, it has also many shortcomings. First, the cost of CSR may become a heavy financial burden. Specifically, CSR tends to be implemented by a company's unilateral backup, and then this may impose a heavy burden on the company. Second, one cannot expect effects of CSR in a short-term. Because of these shortcomings, the unilateral CSR has gone into alteration of the type of CSR since 1980's. Instead of unilaterality, Cause-Related Marketing(CRM) began to be used for mutual profits among company, consumers, and society. That is, CRM has become to be spotlighted as a new type of CSR. It focuses on partnership between a company and consumers based on cause and mutual profit pursuing through this partnership. So, many contemporary companies prefer CRM activities that derive their positive corporate image, that increase their sales, and that reduce their financial cost. The IBM Matching Grants Program, which is the largest of the IBM-Employee partnership programs, is a typical CRM. This program enables employees and retirees to increase the value of their donations to educational institutions, hospitals, hospices, nursing homes, and cultural & environmental organizations with a matching gift from IBM. Hundreds of educational institutions and thousands of nonprofit organizations have benefited from the contributions by IBM. There might be various types of matching grants. For example, an employee might choose a lump-sum expense or partitioning a lump-sum into a series of small ongoing expenses for his (or her) donation, and a firm might match the employee's total contribution with a lump-sum expense or might match the employee's total contribution with a series of small ongoing expenses. However, it is not easy to find an academic research on which type of matching grant is preferred by employees. This paper shows that an employee prefers the type of matching grants that consists of a lump-sum expense for his (or her) contribution and a series of small ongoing expenses for a firm's contribution [or the type of matching grants that consists of a series of small ongoing expenses for an employee's contribution and a lump-sum expense for a firm's contribution] to the other types of matching grants.

Purpose - The Korean government has revised the distribution industry development law to regulate large-scale retailer operations to protecting medium- and small-scale retailers and traditional markets. According to the revised law, large-scale retailers must follow regulations on operating hours and compulsory store closures two days per month. Based on the revised distribution industry development law, most local governments regulate operation hours and they have adopted compulsory closure programs for large-scale retail stores. However, it is argued that fresh food producers suffer from a decrease in sales based on the compulsory closure of stores operated by large-scale retailers. Large-scale retailers reduce their fresh food orders from agricultural and fishery producers because of the compulsory store closures. Fresh food producers also suffer from a decrease in prices because reduced orders lead to a decrease in auction prices based on the availability of excess goods in wholesale markets. This paper investigates the effects of operation regulations for large-scale retailers on agricultural producers by surveying agricultural and fishery producer organizations. Research design, data, methodology - A survey was conducted on 117 producer organizations of fruits and vegetables, cereals, fisheries, and livestock products from September 10 to October 4, 2012. Survey items are annual sales, shares of sales accounted for by large-scale retailers, reduction of orders and prices from large-scale retailers, methods to deal with the sales reduction, unfair trade practices of large-scale retailers, opinion of the large-scale retailer regulations, and so on. The average sales of the sampled producer organizations are 13.7 billion won and the average share of sales accounted for by large-scale retailers is 35.4%. Results - Survey results show that the sample producer organizations' sales decreased 10.1% because of the compulsory closures of stores operated by large-scale retailers. It is estimated that the total sales of producer organizations decreased 371.2 billion won because of the regulations on the operation of large-scale retailers. In addition to the direct effect of a sales decrease due to order reduction, agricultural and fishery producer organizations suffered from the secondary effect of price reduction in wholesale markets. When orders from large-scale retailers decreased, most agricultural and fishery producer organizations shipped redundant products to wholesale markets, decreasing auction prices. It was estimated that the price received decreased 21.9% when sold in other marketing channels. As producer organization sales decreased, it was reported that the labor force employed by producer organizations also decreased by 15.1%. Therefore, we can conclude that the regulations for large-scale retailer operations resulted in negative impacts on agricultural producers. Conclusions - Although the sales reduction due to the regulations for large-scale retailer operations are not great, the cumulative effects due to the continued compulsory closure of stores operated by large-scale retailers could be great. This paper suggests governmental programs that could help agricultural producer organizations to find new and effective marketing channels such as direct marketing, farmers' markets, exports, Internet shopping, and so on.

Morgenthau claims that in international relations, there are the economic, political, and military powers that enable a nation to achieve its political and diplomatic goals. This paper explores the possibility of resolving international conflicts with naval power. First, the theoretical and historical perspective, naval power was used as a final resort to force a nation's political or diplomatic objective on an enemy nation when negotiations failed, and this was done through the physical and psychological destruction of the enemy by naval power. But as the use of military power has decreased because of the invention of the nuclear weapon, the existence of a large and capable navy deterrent has become one of the most useful military options among a nation's diplomatic measures. In other words, he focused on the political usefulness of naval power as a deterrent and coercive diplomatic tool for persuading other nations to acquiesce, rather than using naval power and actual military action as a final resort. The reason for this is that compared to army and air force, navy's flexibility, continuity, and the ability to deter are greater. The navy provides excellent accessibility through its wide mobility on the sea, and it has been shown through research that the navy possesses a political usefulness that facilitates the solution of conflicts through presence, naval intervention, and naval blockade. On the other hand, among the factors that could improve the influence of the navy are alliance relations, a reliable and powerful navy, carrots and sticks that it would have to deal with in the case of successful or unsuccessful negotiations, and support from international opinion. On this paper I introduce E.N.Luttwak's naval suasion theory. By the his theory, there are two mode of naval suasion. One is latent naval suasion the other is active suasion. Latent suasion there are deterrent mode and supportive mode. Active naval suasion there are coercive mode and supportive mode. Coercive mode has positive and negative. The limitations of naval suasion have been identified as follows. First, because the objective of the use of naval power is persuading enemy nations, the results are unpredictable. Second, the leaders of all countries possess limited understanding on the complexities of naval power and therefore lack understanding of the usefulness of naval power when choosing options. Third, in case of failure through naval suasion, prestige and reputation of a nation can be damaged. Finally, the following are additional possible research topic. First, a research on the decision making process of choosing naval power as a measure to resolve conflicts is needed. Lastly, research on the size of the navy and types of ships required for efficient naval suasion is needed. Today's world requires cooperative security regime so that middle class navy also requires political use of naval power in solving international conflicts. Therefore, additional research on this topic is needed.

It is a common wisdom that the long-term economic development of Korea chiefly depends not only on the steady increase of the capital formation but also on the stable increase of the national saving. And also it is a widely accepted opinion that household saving plays a significant role for the smooth supply of investment funds. For the empirical analysis on the determining factors of household saving, consumption function of the household of Korea was utilized indirectly. The reason is that consumption function is regarded as a stable function whereas saving function is considered to be an unstable function of the relevant independent variables. In order to carry out the regression process of the consumption functions, data on the family income and expenditure survey and the farm household economy survey was used. The regression result could be summarized as follows : Firstly, household income and the number of the employed in the household have the negative effect in determining the consumption ratio of the Korean households. On the other hand, ages and the educational attainment of the household heads as well as the number of the household members have the positive effect. During the early part of 21st century, the consumption ratio of the Korean households is expected to be decreased because of the increasing trend of household income, and the ever increasing number of the employed member of the household based on the increasing trend of the labor force participation rate of women and the decrease of the average size of the number of household members owing to widespread nuclear family system. On the other hand, the consumption ratio of the household of Korea is expected to be increased because of the continuous increase of the average ages of the household heads caused by the population aging phenomena and improvement of the educational attainment of the household heads. But on the whole, household saving ratio is expected to be increased owing to the secular downward trend of the consumption and therefore no significant difficulties are anticipated for the smooth provision of investment resources needed to have long-term economic progress of Korea.

Recently, Korean government documented the plan to cope with the situation related to rich pensioners of Basic old-age pension. The purpose of this paper is to verify that how many rich pensioners are existing and to evaluate government reform plan's validity and effect. Main results are as follows; firstly, if the definition of rich pensioners is on the top 10%, the proportion of them would form 2.9% of total. And then, an amount of expenditure for them is only 2.6% of total. Secondly, in terms of disposable income, debt, and transfer income from child, the household who would be applied by government's plan is not richer than other household who is in the same living standard. And then, if the government's plan enforced, the effect might be very small. Lastly, the plan of government will discriminate against persons who support their parent. As a result, Basic old-age pension will be worsen. This paper should underline that the government's reform is only the 'hidden' retrenchment strategy in order to introduce a standard of the obligation to support own parent in the state without scientific prediction and serious discussion of negative public opinion. That is why, this is the same as the 'Trojan Horse'.
