In this study, we explore whether and how the experience of discrimination and social support affects physical health and mental health through disability identity among the disabled aged 50 and over. We also examine such relationship differs by the degree of disability. For the empirical test, we utilized the data from the Panel Survey for the Disabled conducted by our research team in 2016. According to structural equation model analysis, social support has a direct effect on disability identity. It also has a direct effect on physical health. As for the mental health, there are found direct effects of discrimination experience, social support, disability identity, and physical health, Furthermore, social support influences the mental health through disability identity. This finding suggests that social support for the disabled in old age increases disability identity and, in turn, it contributes their mental health. In the meanwhile, multiple group comparison analysis reveals the effect of discrimination experience on disability identity is found for those with lower level of disability but not for their counterparts. This seems to result from that the level of common ground which constitutes disability identity is low for the severely disabled. Thus, it requires our efforts to enhance disability identity focusing on common ground for the severe disabled.

The purpose of this study was to examine the effects of altruism and the civil right consciousness on the ageism against older people. Using data of 1,513 persons over 18 years old from the Korean General Social Survey(KGSS)(2011), this study applied descriptive analyses, t-test, ANOVA, correlation analysis and multi-regression with STATA14. According to results, the degree of ageism was slightly lower(2.43 out of 5). Compared to age groups, the results were followed: elderly, middle age, and young age group. Among them, the ageism level of the group to have experiences of discrimination was higher than one of the group not to have it. The degree of altruism was high(3.95 out of 5), followed by elderly, middle age, and young age group. The group experienced in discrimination had higher level of altruism than another. The degree of the civil right consciousness was high(5.83 out of 7) without differences among age groups. In the results of regression analysis, the ageism was negatively affected by altruism and the civil right consciousness. Based on the results, this study suggested practical and political opinions for reducing ageism.

This study analyzes whether online political activities have an important impact on attitudes toward the legalization of same-sex marriage and the anti-discrimination law and whether these effects are different by the religion of voters. The main findings are as follows. First, the ideology variable has a significant effect on attitude toward legalizing same-sex marriage and enacting anti-discrimination law. Second, the higher the degree of online political activities, the more likely they will support two issues. Third, the effect on attitudes toward the enactment of anti-discrimination law has appeared different by religion. In other words, Protestants, compared to other religions, are more likely to oppose the enactment of anti-discrimination laws as the level of online political activities increased. Our study is meaningful in that we found online political activities play an important role in making voters' attitudes positively toward the enhancement of the right of sexual minorities. Also, although ideological conflicts are usually intense in diplomatic and security issues in Korea, the sexual minority issue would be likely to be an crucial as a dimension of ideological conflicts.

This study examines the service quality management and the use of women employees for the productivity improvement in Korean service industry. Five service industries, bank, hotel, PCS(Personal Communication Service), department store, and hospital industry were chosen for this study. The results indicate that the five industries show different characteristics. It was found that department stores made the most effort to improve service quality among the five industries and that hospitals did the least effort. In the use of women employees, the proportion of women in service industry is much higher than that in the manufacturing industry, but the proportion of women in management level is still very low. Women employees do not feel high degree of sexual discrimination. But they feel unfairness in promotion and payment, and low degree of job satisfaction.

The objective of this study was to analyze the volatile compounds in rice under various milling degrees using a mass spectrometry-based electronic nose and discriminant function analysis (DFA). Less volatile components were more frequently found in rice with a lower milling degree. Milling degree resulted in a shift of DF1 to the left side of the DFA plot. This indicated that the DF1 scores were correlated with the milling degree of rice. Brown rice was found to have more volatile components regardless of the milling degree. Thus, rice prepared at different milling degrees could be effectively discriminated with electronic nose analysis. Moreover, more volatile components were detected with an increase in storage time. A slight change in volatile components was found with an increase in the milling degree. The electronic nose could predict the milling degree and storage time of rice.

Dysfunction of the inferior alveolar nerve indicated by various degree of numbness of the lower lip and chin is one of the few drawbacks of mandibular osteotomy, especially Bilateral Sagittal Split Ramus Osteotomy(BSSRO) and genioplasty. Although it has been recorded throughout the history of this techniques, it is true etiology poorly understood. In this study, 22 consecutive patients under class III malocclusiion impression and undergoing orthognathic surgery(BSSRO only 11 case, BSSRO with genioplasty 11 case) were studied using 4 neurosensory test(static light touch, directional discrimination, two-point discrimination, pin pressure nociception) with post OP 1 week, 2 weeks, 4 weeks, 8 weeks, 12 weeks, 24 weeks, On control group, 10 members without trauma and nerve damage history, nerve test was accomplished. We concluded majority of patients return of sensation during post operative 24 weeks. Althought immediate nerve deficit are 92.2%, 97.2% 88.9% these are recovered to 25%, 35.72%, 10.71% at 24 weeks. Nerve recovery rate increased prominently between post 4 weeks and 8 weeks. There is no statistically difference about neurosensory deficit among the chin area. Neurosensory deficit more severe when the BSSRO with genioplasty group than the only BSSRO group. Immediate neurosensory deficit is larger left side than right side but after 6 months, there is no significantly difference between left side and right side. Static light touch and pin pressure nociception are more sensitive method of neurosensory deficit than two point discrimination.

Chemical characteristics of soybean oil after deep-frying with potato sticks (200 g, 10% w/w of soybean oil) were studied according to the 34 deep-frying times. After consecutive 34 deep-frying, total polyunsaturated FA contents was gradually decreased while the total saturated FA and trans FA were increased. Acid value and peroxide value were increased while iodine value decreased, respectively. The Hunter $L^{\ast}$ value decreased while each $a^{\ast}\;and \;b^{\ast}b$ value were gradually increased. Electronic nose equipped with 12 metal oxide sensors was used for the discrimination of odor pattern of frying oils against the times of deep-trying. The proportions of 1st and 2nd principal component analysis showed 75.97% and 21.23%, respectively. While 6 among total 12 sensors well responded to discrimination of odor in the repented frying oils, suggesting that the odor pattern of each oil after deep-frying would be discriminated against fresh soybean oil, especially after 14 times. From the results, electronic nose could differentiate the degree of quality deterioration of the repeated deep-frying oils.

Purpose - International trade leads to the international division of labor, improving the efficiency of the global economic system. Transport costs are a more serious barrier to international trade than customs tariffs. An increase in competition in the transport sector may thus lead to a reduction in transport costs. However, if a carrier's nationality significantly influences transport costs, simply adding more competing carriers of different nationalities would be ineffective. Therefore, it is necessary to establish national or regional carriers to influence competition and reduce transport costs. This study investigates this "nationality effect" by treating Hanjin Shipping's collapse as a natural experiment. Design/methodology - The theoretical basis of this study is the 3rd-degree price discrimination in container shipping market. By using the monthly data of container freight rates of Korea, China and Japan, this study shows the so-called Korea Premiums, which are the empirical counterparts of nationality effect in Korea container shipping market. For this empirical investigation, the structural model with state-space form is used and the dummy models are also estimated. In addition, because China has been also affected by the Hanjin's collapse, the China premiums are considered too. Findings - Compared with Japan's case, it is shown that there had been the so-called Korea premiums since the collapse of Hanjin Shipping. These results are robust from both the state-space model and dummy models. The time pattern of Korea premiums was consistent with the market evolution, especially the pattern of substitutability in container shipping markets. In addition, this paper shows the magnitude of Korea premiums. Originality/value - The argument of this study that the nationality effect can be interpreted as an extended concept of the home market effect is original, which is expected to evoke future research efforts. Further, the discussion on the shipping industrial policy from both horizontal and vertical aspects will provide the relevant policy makers with solid information, especially for the policy coordination in a global scale.

Despite the government's constant exertions on making a win-win environment through positive discrimination for small and medium-sized companies and local companies, they are suffering from order polarization, weak competitiveness to win a project, and low profitability in highly competitive market situations resulting from the contraction of the construction market. This study examined the U.S. policy and regulations on protecting the relatively weak entities in the construction industry, focused on a goaling program, setting aside the bid preference for small and middle-sized companies and local companies. From benchmarking, some implications were drawn to reconsider the goal of policy and regulations for small and medium-sized companies and local companies. In conclusion, unlike domestic positive discrimination regulations, which are based on the concept of market sharing that can allow a paper company to survive, those of the U.S. are based on the principle of fair competitiveness, and also provide a certain degree of advantage for small and medium-sized companies and local companies. Therefore, the domestic positive discrimination policy and regulations for small and medium-sized companies and local companies need to be reconsidered toward the direction of not only protecting them but also to strengthen their competitiveness in the market.

The purpose of this study was to figure out the various characteristics of the thickness sensation among elements of tactile sensation using psychophysical method. Firstly, panel screening was processed to select sensitive thickness panel using the triangle test. As a result of discriminating the paper thickness difference from 1 to 4 pieces, the female students perceived the thickness difference more sensitively than the male students (p<.05). Secondly, JND (Just Noticeable Difference) was obtained at percentage of stimulus detection rate in order to detect the degree of thickness difference by psychophysical method. It was found that the difference threshold of the entire group was about 0.125mm, with male group being about 0.178mm and female group being about 0.095mm. Thirdly, Weber's law was used to find the minimum discrimination difference between the stimuli. The experiments were conducted by increasing the paper's base thickness from 1.950mm to 1.330mm, and it was found that the difference tendency increased when the size of the basic stimulus increased. At this time, the minimum discrimination difference increased, but the Weber' fraction was not proportional to the magnitude of the stimulus. The significance of this study was that sensory evaluation was applied to research in the fields of clothing science and it seems effective to further screen and train sensitive students as material discrimination experts.
