This paper compares the realities of the salary Peak Policy's status and management processes in Korea and Japan, with the aim of determining the development direction for Korea's salary Peak Policy's. Unlike Japan, which successfully achieved close cooperation between government, firms and workers in implementing the Retirement Age Extension Type salary Peak Policy, Korea experienced many problems due to lack of preparation. In order to rationally develop the salary Peak Policy, the government, firms, and workers must cooperate to increase the policy's efficiency via the following steps. First, gradually increase the proportion of retirement age extension. Second, career development that takes into account the various employment types, flexible working hours and aged workers. Third, development of training programs for senior citizen workers, as well as increasing support for changing of jobs and startups. Fourth, expansion of re-employment after retirement age and ways to make use of the skilled labor. Fifth, increasing work efficiency through bonuses and work evaluation that is specialized for aged workers. This paper argues that such measures are necessary for the co-existence of firms and workers, as well as for improving employment stability and labor market flexibility.

In 2011, greenhouse gas emissions of transport sector were 85.04 million $tonCO_2eq$ and road emissions accounted for 95% of total emissions in the transport sector. There are few innovative technologies to reduce greenhouse gas emissions aside from eco-driving education and public relation program. Therefore, this paper focused on analyzing optimal acceleration by certain road grades and suggested fuel-efficient driving method for various uphill sections. Scenarios were established by driving modes. Speed profiles were generated by scenarios and speed variations. Each speed profile applied to Comprehensive Modal Emission Model and then each fuel consumption was estimated. Driving mode and speed variation that minimized fuel consumption were driven according to grade percent and uphill distance. When driving in the eco-friendly mode of the driving and speed variation, reduction rate of fuel consumption was evaluated by comparison between eco-driving and cruise control mode. When a vehicle drove under eco-driving mode at 100kph, 90kph and 80kph on uphill road, fuel consumptions were reduced by 33.9%, 30.8% and 5.3%, respectively.

While there are various opinions about the relationship of Schiller's thought and Kant's, it is undeniable that Schiller owes much to Kant. What distinguished Schiller from other Weimar thinkers at his time, such as Goethe, Herder and Wieland, was that unlike them Schiller accepted Kant's project of critical philosophy. In fact, Schiller did not just accept it, but tried to interpret and formulate anew the relation of beauty and morality and some other aesthetical-ethical ideals on the basis of the new philosophy. Schiller's famous project of 'aesthetic education of mankind' itself is the product of such an endeavor. In this work we follow the history of Schiller's acceptance of Kant's critical philosophy and ruminate over its implications. And then, we'll show that Schiller's 'beautiful soul' in Grace and Dignity (1793), which is often suggested to be a proof of Schiller's conflict with Kant, was understood on the basis of Kant's moral theory. In this part of the work, we compare Schiller's ideal of the 'beautiful soul' and Shaftesbury's ethical thought, which is often presumed to be its background. From this comparison we'll be able to see that there is a considerable disparity, despite apparent similarities, between Schiller's and Shaftesbury's ethical ideals, which is due to their respective philosophical sources, that is neo-platonic metaphysics and Kant's critical philosophy.

This study analyzed characteristics of landform relieves on 12 bedrock whole(W) areas and 24 mountain(M) and valley(V) areas. Based on this result, characteristics and relations between bedrocks and landform relief were classified as follows. 1) gneiss-height M and granite-height W, M, V areas show active stream incision for uplift. However these areas have relatively low relief and grade compared to high altitude, because effect of denudation don't pass on whole slope. 2) gneiss-height W, V, gneiss-mid M, schist M, granite-mid M, volcanic rock W, M, sedimentary rock-height(conglomerate) W, M, V, sedimentary rock-mid (sandstone and shale) M, limestone W, M areas have active stream erosion and mass movement, but landform relieves are on the high side, because these have resistant bedrock and geological structure against weathering and erosion. 3) gneiss-mid W, V, schist W, V, granite-mid W, V, volcanic rock V, sedimentary rock-mid W, V, sedimentary rock-low(shale) M, limestone V areas landform relieves are on the low side, because these have weak resistance and active weathering, mass movement, erosion, transportation and deposit. 4) gneiss-low W, M, V, granite-low W, M, V, sedimentary rock-low W, V areas landform relieves are very low, because these don't have active erosion and mass movement as costal area with low altitude.

Objectives The aim of this study is systematic evaluation of the quality of qualitative studies related to short stature. It will be utilized as fundamental data for future qualitative research about Korean Medicine Pediatrics treatment for short stature. Methods We searched qualitative studies related to short stature in the Pubmed. Two researchers independently assessed the quality of the qualitative researches by using Consolidated criteria for reporting qualitative research (COREQ) and Critical Appraisal Skills Program (CASP). We also qualitatively synthesized theme of each included studies. We presented integrated theme and categories with in vivo coding about qualitative research about short stature. Results A total of 47 papers were screened and 7 papers were finally selected. In the quality assessment using COREQ, detalied information about the researchers, methods of approach, reasons for non-participation, presence of non-participants, participant's review of the transcript, and participant's review of the findings were insufficient. In the quality evaluation using CASP, there were lack of justifications for the research methods, description method of research, and bias in process of data analysis. The findings were synthesized into three themes: fixed idea about height, discomfort caused by small stature and personal coping strategy with stress caused by short stature. Conclusions In further qualitative research, it is necessary to report the research according to COREQ and CASP checklist. It is also necessary to understand the stress and coping strategies to short stature of patients, We need to develop a social management strategy for short stature.

Objectives: We aimed to examine the association between the relative preference for vegetables and meat and cancer incidence, in a population-based retrospective cohort in Korea. Methods: We included 10,148,131 participants (5,794,124 men; 4,354,007 women) who underwent national health screening between 2004 and 2005 from the National Health Information Database of the National Health Insurance Service (NHIS-NHID). Participants were asked whether they preferred consuming 1) vegetables more often, 2) both vegetables and meat or 3) meat more often. Participants were followed up to Dec. 31, 2017. All cancer and eighteen common cancer cases were identified through the code from the International Classification of Diseases, 10th revision. We estimated sex-specific relative risks and 95% confidence intervals, adjusting for age, body mass index, alcohol consumption, smoking, physical activity, and income level. Results: During an average follow-up of 12.4 years, 714,170 cancer cases were documented. In men, consuming meat more often was associated with lower risk of esophageal, liver, and stomach cancers, but higher risk of lung and kidney cancers. Consuming both vegetables and meat was associated with higher risk of prostate cancer, but with lower risk of esophageal, liver, and stomach cancers in men. In women, consuming meat more often was associated with a higher risk of colorectal cancer and breast, endometrial, and cervical cancers diagnosed before the age of 50. Consuming both vegetables and meat was associated with lower risk of liver cancer in women. Conclusions: Our study suggests a potential link between vegetable and meat intake and cancer incidence in the Korean population. Further investigation on the association between the intake of specific types of vegetables and meat and cancer risk in Korean prospective cohort studies is needed.

This study investigates the formation mechanism of columnar joints at the Sanin Kaigan Geopark in Japan based on its morphology, rock type and igneous structure. Columnar joints distribute to five areas of three prefectures. That is, Kyogasaki, Byobuiwa, Tateiwa and Kyugenkado in Kyotango area of Kyoto prefecture; Genbudo and Kinumaki Shrine in Toyooka City of Hyogo prefecture; Yoroinosode, Takanosushima, Mini-Yoroinosode in Kamicho Town of Hyogo prefecture; Miooshima and Nagasakihana, Shitaara Domon, Kuzakuishi, Moroyose dyke in Shinonsencho Town of Hyogo prefecture; Shirawara dyke in Iwamicho Town in Tottori prefecture. Igneous structures are divided into three types: lava flow, sill and dyke. Lithologies are divided into five types including basalt, andesite, dacite, rhyolite, and quartz porphyry. Lava flow shows colonnade and entablature. However, entablature is not seen in the sills and dykes in the area. Although the polygons of columnar joint vary from tetragon to octagon, hexagon is most frequently found. The width of colonnades ranges from 10cm to 1m, but their size does not correlate with its $SiO_2$ contents. Meanwhile, their size and morphology at single site are comparatively uniform.

Mobilization of storage lipids is critical for the germination of oil seeds, as they supply carbon and energy until photosynthesis commences in cotyledons. In this study, we determined the levels of plant carnitine and associated changes in these levels from seed germination to cotyledon senescence. We also examined changes in the content of unsaturated fatty acids throughout seedling development. Carnitine levels peaked on day 3 at 14.5 nM in cotyledons and decreased sharply to 7.2 nM on day 4. On development day 3 carnitine levels were maintained at around 3 nM until day 7. The unsaturated fatty acid content dropped by half at the same time as carnitine peaked (day-3), and storage lipids were almost depleted by day 5. Thereafter, carnitine was hardly detected until the second stage of cotyledon senescence, at which stage the carnitine content was 6.8 nM, similar to that on day 4 at the time of fatty acid depletion in the cotyledons. Unsaturated fatty acids levels remained constant in green cotyledons but slightly increased in the senescing cotyledons. The latter can be explained by intracellular breakdown of membrane lipids. This is the first such discovery in developing cotyledons and may offer clues regarding other roles of the acetyl unit transport system in plants. The expression of BOU was closely associated with carnitine metabolism during seed germination and cotyledon development. The results provide support for the possibility of carbon re-routing during the glyoxylate cycle in the supply of energy for early germination and development.

This study was conducted to investigate the levels of self-esteem, rehabilitation motivation and quality of life and to identify the influencing factors of quality of life in stroke patients who were receiving rehabilitation therapy. Data were collected from February 22 to March 20, 2016 using self-administered questionares and the data from 216 participants were analyzed using SPSS WIN 21.0 program(SPSS Inc., Chicago, IL, USA). The results of this study were as follows: the mean self-esteem was 3.09/5, rehabilitation motivation was 3.60/5, and quality of life was 2.95/5. Sex, age, education, caregiver, occupation, duration after attack, the degree of disability(dependence), and cognitive function were significantly associated with quality of life. There was positive correlation between quality of life and self-esteem(r=.45, p<.001) and there was positive correlation between quality of life and rehabilitation motivation(r=.27, p<.001). Variables such as self-esteem, duration after attack, the degree of disability(dependence), and cognitive function explained 43.6%(F=14.87 p=<.001) of the variance in quality of life in model 3. Consequently, it is needed to develop and apply nursing intervention and programs for improving self-esteem during rehabilitation in order to improve quality of life of stroke patients.

This study aimed to identify factors that had an influence on preventive behaviors of Emergency Medical Service students against tuberculosis to promote their preventive behavior. The subjects of the study were 314 students studying emergency medical service from one 4-year college and two 3-year colleges in Jeollabukdo and they were researched with the use of a questionnaire from June 25, to July 6, 2018. For a statistical analysis of the data obtained, this study used SPSS 18.0 and conducted a t-test, an ANOVA, a Pearson's correlation coefficient and a multi-regression test to analyze the data. Pearson's correlation coefficient analysis showed that the preventive behavior levels was significantly correlated with knowledge of tuberculosis (r = 0.268, p <0.001) and attitude (r = 0.394, p<0.001). As results of the multi-regression test, the higher the knowledge of tuberculosis(${\beta}=0.152$, p<0.001) and the higher the attitude(${\beta}=0.052$, p<0.001), the higher the preventive behavior levels. In addition, Students who have experienced tuberculosis in their own or relative's relatives have a high level of prevention behavior(${\beta}=-0.186$, p=0.001). Therefore, it is suggested that organized and consistent education programs to promote knowledge on tuberculosis, change negative perception on it and improve preventive behavior levels should be developed and provided.
