This paper analyzes the determinants of wage for the college and university graduates utilizing both individual-level and industry-level variables. We note that wage determination has multi-level structure in the sense that individual wage is influenced by individual-level variables (level-1) and industry-level (level-2) variables. Then, the assumption that individual wage is independent in the classical regression is violated. Therefore, this paper utilizes the hierarchical linear model (HLM). The major results are the followings. First, the multiple correspondence analysis including level-1 and 2 variables reveals that both level 1 and level 2 variables affects individual wages judging from the fact that the values of level 1 and level 2 variables differ across the different level of individual wage groups. Second, the decision tree analysis including level-1 and 2 variables shows that the most influential variable in wage determination is industry-level wage and the next is industry-level working hour, ages and sex in the decling order in. This suggests that the utilization of the HLM is appropriate since the characteristics of industry is important in determining the individual wage. Third, it is shown that the HLM model is the best compared to the other models which do not take level-1 and level-2 variables simultaneously into account.

This paper reviews the Interpretative Guidelines on EU passenger rights regulations in the context of the developing situation with COVID-19 of EU commission. To enlighten the obscurity and to mitigate the economic impacts of the COVID-19, European Commission has published "Interpretative Guidelines on EU passenger rights regulations in the context of the developing situation with Covid-19" on March 18, 2020. The Guideline essentially aims to create a coherent system of rules to assist the passengers, industry and national authorities overall under the unprecedented circumstances across the European Union. To do so, the Guideline is drafted to cover the rights of passengers travelling by air, rail, ship or bus/coach, maritime and inland waterways, as well as the corresponding obligations for carriers. From an aviation industry focused perspective, by referencing the Regulation (EC) numbered 261/2004, the Guideline specifically applies to cancellation and delay in flights which are seen as the dark spots for the air carriers concerning potential burdens.

U. S. commercial landings of wild salmon have remained relatively stable for the past 5 years, averaging 300,000 MT. While the same period, U. S. imports of fresh salmon have increased over ten fold from 1.8 to over 19 million pounds. Over 70 percent of the new supplies of fresh salmon come from Norway. Norway exports to the United States were negligible in 1980 and 1981. However, U. S. imported 1,768 M. T. in 1983, 3,896 M. T. in 1984, and 6,272 M. T. in 1985. Over the past 5 years, import price of fresh wild salmon from Canada has declined steadily from ＄2.58 per pound to ＄1.25 per pound in 1985, while those from Norway had remained unchanged, ranging from ＄3.28 to ＄3.45 over the same period. Norway's cultured salmon entered the United States in 1985 at about ＄3.35/1b., roughly triple the price of Canadian fresh wild salmon imports. U. S. apparent consumption of fresh and frozen salmon has sharply increased from 50,000 MT in 1981 to 92,000 MT in 1985, up 86 percent over the five years. Annual per capita consumption has increased steadily from 0.47 pounds in 1981 to 0.85 pounds in 1985. The estimated demand models show that the annual wholesale price of fresh salmon in the U. S. market would be declined by increase in supplies and would be raised by increase in the U. S. GNP. The empirical results in this study show that wholesale price of fresh salmon in 1990 would remain unchanged at the 1985 level, under the following condition: 1) Norwegian production of Atlantic fresh salmon would reach 80,000 MT (176 million pounds by 1990) 2) Imports of Norwegian Atlantic fresh salmon would keep the same percentage (21%) of Norwegian productions in 1990 3) Imports from other countries and U. S. domestic production would increase and maintain the same level of 25% of U. S. total supplies in 1990 4) U. S. GNP would increase by ＄200 billion annually, slightly less than in the past years.

This study aims to review the standard operation status on wood, pulp and paper industry in Korea according to the industry standardization law which has been revised for strengthening expertise of relevant department and to propose a management strategy of Korean Standards (KS) in figure. Korea Forest Service (KFS) is the responsible department of managing KS on the wood, pulp and paper industry from 2015, and currently opertates three expert committees (wood and wooden construction, wood-based materials, pulp and paper) and wood and paper industry council to review 426 standards. To support an improvement of technical competency and securement of marketability of Korean wood industry, it is about time to review the standards and to develop practical standards since it is managed by specialized department. For this purpose, it is necessary to establish a systematic approach on the management of KS, based on thorough analysis of current KS. To remove possible technical barrier on trade due to the differences of standards between countries, the conformity with international standards is necessary. Also, for sustainability of standard management system, training specialists and building their capability is essential.

Franchising has long been an effective form of distribution that is used primarily by manufacturers whose product lines are especially suited exclusive or highly selective distribution. By IFA(International Franchise Association), franchising is defined as a continuing relationship in which the franchisor provides a licensed privilege to do business, plus assistance in organizing, training, merchandising, and management in return for a consideration from the franchisee. Thus franchising is a method for the owner(franchisor) of product, service, or method to obtain retail or wholesale distribution through licensed, affiliated dealers(franchisees). With rapid increase of franchising industry globally, franchising industry is very rapidly increasing especially in the sector of outdoor restaurant industry in Korea. But there are many problems to be settled for promoting this industry. For example, the industry is too much lean outdoor restaurant industry. With franchisors' short history and lack of management capacity, shortage of distribution infrastructure, smaller size of franchising system, and low trust between franchisor and franchisee, and so on, the industry has many barriers to overcome for promoting it. Here we are suggesting that taxation benefaction, monetary support for the starting franchisee, establishment of fair trade principle, promoting information system and professional human resource should be needed.

This study aims to understand the differences in cultural and emotional perceptions about the color image of public healthcare facilities in Romania, an Eastern European country that is relatively lacking in recognition but is gradually expanding trade. For this, color images were selected through a review of previous studies, and a questionnaire survey was constructed based on the colorimetric data by visiting 8 public healthcare facilities such as medical facilities, 4 social sports facilities, and 8 nursing facilities. An online survey was conducted on the color image of public facilities with 89 Koreans and 86 Romanians, and frequency and cross-analysis was conducted using the SPSS statistical analysis program to examine the color images of public healthcare facilities of Koreans and Romanians. The difference in perception was identified. As a result, it was found that there was a statistically significant difference in the perception of color images of public healthcare facilities between countries in vocabulary evaluation and image evaluation, and this was interpreted as different meanings for groups residing in different cultures. Therefore, it implies that cultural differences in perception should be considered when establishing an environment related to this in the future.

This study investigates the question of how political and economic factors may affect the export of renewable energy technologies. The relationships are tested using panel data for 19 OECD member countries over the period 1992-2012. Before establishing the empirical model, the current study checks the characteristics of the panel data, which includes various panel framework analyses, such as tests for the presence of normality, structural breaks, first-order autocorrelation, heteroscedasticity, cross-sectional dependence, panel unit-root. From the panel framework analyses, a dynamic panel model is established to test the relationship between the variables examined in this study. In order to reduce the bias of the estimation of the dynamic panel model and obtain efficient parameters, this study uses the bias-corrected least square dummy variable(LSDVC) estimator to estimate the empirical model. The results of this study show that governmental policies expressed as coercive pressure and market size positively affect the export growth of renewable energy technologies. However, public pressure and traditional energy industry have no significant effects on export performance. Policy implications are presented based on the results of this study.

PURPOSES : The purpose of this study is to suggest a basis for setting appropriate safety goals specifically related to the threshold zone luminance in a vehicular traffic tunnel. METHODS : In the test, drivers were divided into two groups. One group consisted of all drivers (average drivers) group with an age ratio of drivers holding domestic driver's license and driver group by age to produce threshold zone luminance in the tunnel. The threshold zone luminance produced as a result was used to analyze how it affects the safety level of each driver group and provide a basis for setting an appropriate safety criterion that can be used to determine threshold zone luminance. We used test equipment, test conditions, and ananalysis of threshold zone luminance identical to that reported by ChoandJung(2014) but the values of adaptation luminance in our analys is were expanded to range from100 to $10,000cd/m^2$. RESULTS : Adaptation luminance and threshold zone luminance are found to be related by a quadratic function. The threshold zone luminance needed by older drivers to ensure a certain safety level is significantly higher than that for drivers of other age brackets when adaptation luminance increases. 56% of older drivers are at an increased risk of an accident at the same luminance for which the safety level of average drivers is 75%. The safety level that can be achieved for older drivers increases to above 60% when threshold zone luminance level is set with the goal of attaining a safety level of more than 85% for average drivers. The safety level that can be attained for average drivers is above 90% when the threshold zone luminance is high enough to ensure over 75% in the safety level of older drivers. Results of this study are applicable to highways and others whose designed speed is 100 km/h. CONCLUSIONS : Threshold zone luminance determined on the basis of drivers having average visual ability is of limited value as a performance standard for ensuring the safety of older drivers. Hence, safety level for older drivers should be considered separately from safety levels for drivers with an average ability to avoid risk. Upward adjustment of older drivers' safety level in the process of determining appropriate threshold zone luminance in a vehicular traffic tunnel may bring both tangible and intangible benefit as a result of reducing accidents. However, there is an associated dollar cost arising from installing and operating lights. As a result, the economic impact of these trade-offs should also be considered.

Our economic system highly depends on the international trade market and demands high level of foreign language abilities to the young generation. Scores of various internationally authorized language tests are used to estimate students's language ability before giving their admission to universities or high schools. According to increase of unemployment rate of the young people, universities put their strength on the language abilities of their students, and each university uses some authorized language scores before determining students who win scholarships. This study suggests two types of indices to evaluate students's relative achievement of foreign language abilities between two time points considering their current abilities. One, named one-side relative achievement index, is defined as the ratio of additional score between two time points to the remaining score at the base time point to the full score. The second one, named two-side relative achievement index, is defined as the same manner as the first one if the score is improved, and if not, is defined as the ratio of the amount of losing scores to the current score at the base time point. Two-side achievement index is more useful since it has smaller variation than the former and is easier to interpret. However, both indices are useful to compare the achievements of different tests.

Our society's modernization created many opportunities for us to need a private investigation service system. Variation of international environment due to joining in the OECD, opportunity of individual legal, collect evidence during judgement, prevention of damage criminal, security of business in company, free trade economy's system etc and don't need to enumerate how important of introduction of private investigation service system. In addition to there are lots of objection opinions, such as possibility of person's private life, invade of lawyer's area, confliction with investigation team, gap of wealth and poverty that make preponderance of information. So this research can be considerate from objective opinion, and can obtain conclusion just like below. First, private detective agencies that encroach on the individual rights will naturally deteriorate after the implementation of private investigation service system. Through this, the probability of civil rights encroachment will be lower, and for this to happen there needs to be a thorough maintenance of the system. Secondly, mutually beneficial solution should be found not by a conflict between two sides. Detective business sector should not cause social confusion from conflicts with other investigation organization such as police, or investigators, rather, it must get on the demand of the diversified citizen and maintain the diverse sector inter-cooperate right, and to do that law and institution must be made for the base. Thirdly, investigation used depending on the gap between wealth and poverty does not mean the actualization of the rights and interests of the citizen. If the duty of investigation sector is to find the evidence and collect or manufacture of the evidence, then the problems which the nation can't handle will be more enlarged and then finally end up with strengthening the capability of national public security demand.
