  • When a route choice is done under uncertainty, a driver has some expectation of traffic conditions that will occur according to the route chosen. This study tries to build a framework in which we can observe the learning behavior of the drivers' expectations of the travel time under nonstationary environment. In order to investigate how drivers have their subjective expectations on traffic conditions in response to public information, a numerical experiment is carried out. We found that rational expectations(RE) formation about the route travel time can be expressed by the adaptive expectation model when the travel time changes in accordance with the nonstationary process which consists of permanent shock and transient shock. Also, we found that the adaptive parameter of the model converges to the fixed value corresponding to the route conditions.

  • Head-lice infestation, pediculosis capitis, remains a public-health burden in many countries. The widely used first-line pediculicides and alternative treatments are often too costly for use in poor socio-economic settings. Ivermectin has been considered an alternate treatment for field practice. This study was composed of 2 parts, a cross-sectional survey and an intervention study. The main objectives were to determine the prevalence and potential factors associated with head-lice infestation, and to evaluate the effectiveness and safety of oral ivermectin administration. A community-based cross-sectional survey was conducted among 890 villagers in rural areas along Thai-Myanmar border. Females with infestations were eligible for the intervention study, and 181 participated in the intervention study. A post-treatment survey was conducted to assess acceptance of ivermectin as a treatment choice. Data analysis used descriptive statistics and a generalized-estimation-equation model adjusted for cluster effect. The study revealed the prevalence of head-lice infestation was 50% among females and only 3% among males. Age stratification showed a high prevalence among females aged <20 years, and among 50% of female school-children. The prevalence was persistent among those with a history of infestation. The major risk factors were residing in a setting with other infected cases, and sharing a hair comb. The study also confirmed that ivermectin was safe and effective for field-based practice. It was considered a preferable treatment option. In conclusion, behavior-change communication should be implemented to reduce the observed high prevalence of head-lice infestation. Ivermectin may be an alternative choice for head-lice treatment, especially in remote areas.

  • Purpose: The purpose of this study is to quantitatively identify the environmental contribution generated by urban rail users in the metropolitan area. Method: As for the analysis method, the mode choice and assignment of the traffic demand analysis were repeatedly performed on the assumption that each line was not opened for the metropolitan urban railway lines 1 to 9. After that, the environmental contribution according to changes in demand for the road was analyzed. Result: The total amount of carbon dioxide emissions and benefits were found to be the largest for subway line 1. However, when considering the number of stations and length, it was analyzed that the environmental contribution was the greatest in Metro Line 4. Conclusion: Measures to promote the use of public transportation are representative of environmental improvement policies, but there is a limit in that it is difficult for actual users/non-users to feel it. Therefore, it is judged that it is necessary to quantitatively present the effect in order to improve and spread awareness of the environment.

  • It is the most critical issue in recent international intellectual property licence disputes to decide the applicable laws to the license contracts. As Korea and the European Union(EU) reached free trade agreement(FTA), and the EU-Korea FTA entered into force on July 1, 2011, the FTA has boosted social, economic, cultural exchanges between the two. As a result of the increased transactions in those sectors, legal disputes are also expected to grow. This situation calls for extensive research and understanding of the choice of law principles applicable to international intellectual property license contracts in the EU. To decide the laws applicable to issues arising from international intellectual property license contracts disputes, the characterization of those issues is necessary for the purpose of applying private international law principles to them. In terms of characterization, intellectual property license contracts fall within contractual matters. In the EU, the primary rule of choice of law principles in contractual obligations is the Rome I Regulation. Because the choice of law rules, such as private international law principles, the Rome Convention(1980), and the Rome I Regulation, differ in the time of application, it is essential to clarify the time factor of related contracts. For example, the Rome I Regulation applies to contracts which were concluded as from December 17, 2009. Although party autonomy in international contracts disputes is generally allowed, if there is no choice of law agreement between the parties to the contracts, the objective test rule of private international law doctrine could be the best option. Following this doctrine, the Rome I Regulation Article 4, Paragraph 1 provides the governing law rules based on the types of contracts, but there is no room for intellectual property license contracts. After all, as the rule for governing law of those contracts, the Rome I Regulation Article 4, Paragraph 2 should be applied and if there are countries which are more closely connected to the contracts under the Rome I Regulation Article 4, Paragraph 3, the laws of those countries become the governing laws of the contracts. Nevertheless, if it is not possible to decide the applicable laws to the license contracts, the Rome I Regulation Article 4, Paragraph 4 should be applied in the last resort and the laws of the countries which are the most closely connected to the contracts govern the license contracts. Therefore, this research on the laws applicable to intellectual property license contracts under the Rome I Regulation suggests more systematic and effective solutions for future disputes in which Korea and the EU countries play the significant role as the connecting factors in the conflict of laws rules. Moreover, it helps to establish comprehensive and theoretical understanding of applying the Korean Private International Law to multifarious choice-of-law cases.

  • Design is an extremely critical and important for the prosperity and development of a corporation, and design for children's facilities can be said to be a critical factor not only from a commercial perspective but also one of the critical factors that can be beneficial to the physical, intellectual and emotional growth and development of children. To measure the economic value of publicly designed children's facilities established with the purpose of children's design education, this research study utilized the Contingent Valuation Method. This research study attempts to provide useful information for policy administrators on the usage of both publicly designed children's facilities with high use value and also high non-use value through economic value measurement. To achieve the objectives of this research, the Contingent Valuation Method that utilized both open-ended questions and also double-bounded dichotomous choice methodologies was used. The results of the pre-verification that used the open-ended questions results from 50 test subject participants and the double-bounded dichotomous choice methodology results from 530 test subject participants confirmed that the average annual per person expense was estimated to be KRW 12,463. The gross benefit amount figure estimated for all households in the nation was estimated to be about KRW 219 billion annually.

  • Although various publicly reserved funds have recently come to the fore of academic and policy-making attention in Korea, researchers rarely take up the issue of the reserve fund retained from annual profits by the central bank (i.e., the Bank of Korea). Starting with the general public choice premise that bureaucrats seek to maximize their discretionary budget, this paper first provides a theoretical reasoning why central bank's bureaucrats would prefer retaining annual profits to turning them to the Treasury. The major tenet to be emphasized is that retained profits as a reserve fund can give the central bankers discretionary power in their disposition. In particular, we focus on the close relationship between the reserve fund and the discount windows. The latter, as a monetary instrument, has traditionally been demonstrated to cause secrecy, arbitrariness, and other bureaucratic amenities in the previous literature. Subsequently, this paper, based on 61 countries data, empirically verifies that the central bank's reserve fund is at least partially used to additionally increase the discount windows. Since an excessive use of discount windows results in inflationary bias, we conclude the paper with some policy suggestions to have such bureaucratic power of discretion in check. This paper, if in its experimental nature yet, is expected to shed a critical implication for establishing the meaningful independence of the central bank to a host of countries.

  • In the second half of the previous century the composition of the teacher population - and the composition of the pupil and parent population - in the Netherlands gives rise to the name change 'age of secularisation' to 'age of pluralisation'. In previous centuries the (religious or secular) worldview identity of the parents and the educational philosophy of the school were attuned to each other, and merged into a mono-cultural perspective on the identity development of pupils. The basis for both - the upbringing by the parents and the socialisation in the family on the one hand, and the teachers' efforts to enculturate the students at the school on the other - was a similar life orientation. The school choice of the parents was predetermined by their commitment to a particular (religious) worldview, very often inspired by Christianity. The religious identity of their children developed in a clear-cut context. However, in contemporary society plurality dominates, at home and at the school, both in case of the parents and the teachers. A direct relationship with a community of like-minded believers is no longer decisive for parents with varying cultural and religious backgrounds. Instead, a good feeling upon entering the schoolyard or the school building is a convincing argument in the process of school choice. The professional identity development of teachers and the religious identity development of children takes place in a plural context. Our question is: what does this mean for the normative professionalism of the teacher? To answer this research question we make use of the resources of the Dialogical Self Theory (DST) with its core concepts of 'voice' and 'positioning'. After presenting the Dutch dual education system (with public and denominational schools) we provide a lively description of a Dutch classroom situation occurring in a public school, as viewed from the perspective of the teacher. The focus in this description is on performative dialogue as a 'disruptive moment' and on its potential for the hyphenated religious identity development of teachers, which makes up a part of their normative professionalism.

  • This article argues that public service broadcasting (PSB) should be transformed into public service media (PSM) in order to accommodate the concept of universal service in this media convergence age. If we utilize the universal service concept of telecommunications in this purpose, it inevitably constrains the concept to "access to general information" and has a limitation in its scope. In contrast, the application of the broadcast perspective leads to only examine the possibility of expanding the universal service obligation to new platforms, which has been applied to terrestrial broadcasting. As a result, these two approaches have no choice but to stay in limited area such as low-income assistance. Thus, in conclusion, it is necessary to convert PSB to the PSM as a means of providing the socially required content universally, which commercial market cannot easily produce.

  • Purposes: This study identifies local Chinese consumers' standard for selecting medical care provider and their standard for choosing medical staff, as well as their expectations and concerns regarding Korean medical care providers. Methodology: A survey was conducted in China, to identify Chinese medical care consumers' standards for selecting a medical provider and the factors that influence their use of general hospitals. A total of 1,500 people across three cities, between the ages 18 and 60 participated in the survey. Moreover, a multiple logistic regression analysis was used to analyze the factors that affect Chinese medical care consumers' use of general hospitals. Findings: A total of 75.5 percent respondents chose general hospitals as their most frequently-used medical provider. Those who have health insurance, visit general hospitals as outpatients or are hospitalized more frequently than those who do not have a health insurance. Furthermore, those who have private insurance visit general hospitals as outpatients or are hospitalized more frequently than those who are not signed up for private insurance. Major standards for selecting a hospital included: the doctor's skills, word-of-mouth regarding the hospital, and distance to the hospital from the respondents' home. Standards for choosing medical personnel included word-of-mouth regarding the medical team, recommendations from family members or acquaintances, and medical team's notoriety. Friends and neighbors, family members, television and other media outlets were the channels for acquiring information on a hospital. It was found that Chinese people mostly visit the cardiovascular department of Korean hospitals for treatment. For using Korean hospitals in China, the majority of respondents answered that they were concerned about the cost. Practical Implications: Backed by highly skilled medical experts and cutting-edge technology, Korean medical care providers are attempting to enter China's medical care market. To succeed in China's medical care market, it is vital to conduct a clear and precise analysis.

  • This study is a descriptive research study to examine influence of major satisfaction and career maturity on the job-seeking stress of nursing and public health university students. This study surveyed 410 nursing and public health university students from 3 schools of G-city from September 26 to October 31, 2017. The data were analyzed by descriptive statistics, ANOVA, ANCOVA, Pearson correlation coefficients, and multiple regression. The study results showed a significant difference in major satisfaction (F=9.856, p<.001) and career maturity (F=6.005, p=.001) according to major choice motives. The student GPAs were also found to be significantly different from career maturity (F=2.755, p=.042) and job-seeking stress (F=3.503, p=.016). In addition, the TOEIC score was significantly different from major satisfaction (F=4.514, p=.004). Job-seeking stress was positively correlated with major satisfaction (r=-.314, p<.001) and career maturity (r=-.514, p<.001). The factors affecting job-seeking stress were in the order of major satisfaction (${\beta}=-.125$, p=.007) and career maturity (${\beta}=-.459$, p<.001). Based on the results, two proposals are recommended in order to reduce the job-seeking stress of nursing and public health university students. It is necessary to prepare major guidance programs suitable to the characteristics of each department from the lower grades and to provide the students with career guidance accordingly.
