An interpretation of the relation between the electric field and the applied current for cathodic protection is investigated usinga boundary element method simulation. Also, a conductivity-difference environment is set for the interface influence. Thevariation of the potential distribution is increased with the increase of the applied current and the conductivity differencedue to the rejection of the current at the interface. In the case of the electric field, the tendencies of the increasing rate andthe applied currents are similar, but the interface influence is different according to the directional component and field type(decrease of Ez and increases of Ex and Ey) due to the directional difference between the electric fields. Also, the changetendencies of the electric fields versus the applied current plots are affected by the polarization curve tendency regardingthe polarization type (activation and concentration polarizations in the oxygen-reduction and hydrogen-reduction reactions). This study shows that the underwater electric signature is determined by the polarization behavior of the materials.

Background: Woori-Heukdon (KWH) is a Korean synthetic pig breed generated using Chookjin-Duroc (KCD), Chookjin-Chamdon (KCC), and their crossbreds. Currently, there is a severe lack of studies investigating the Korean breed populations including wild boars (KWB) throughout the genome. Objective: This study was performed to investigate the genetic characteristics of Korean pig populations at the genome-wide level. Methods: Using the SNP dataset derived from genotyped and downloaded datasets using the Illumina PorcineSNP60K BeadChip, we compared the genomes of 532 individuals derived from 23 pig breeds to assess the genetic diversity, inbreeding coefficient, genetic differentiation, and population structure. Results: KWB showed the lowest average expected heterozygosity (HE = 0.1904), while KWH showed the highest genetic diversity (HE = 0.02859) among Korean populations. We verified that the genetic composition of KWH, showing USD of 74.8% and KCC of 25.2% in ADMIXTURE analysis. In population structure analyses, KCC was consistently shown to be separated from other pig populations. In addition, we observed gene flow from Western pigs to a part of Chinese populations. Conclusion: This study showed that Korean native pigs, KCC have genetic differences in comparison with Chinese and Western pigs; despite some historical records and recent genetic studies, we could not find any clear evidence that KCC was significantly influenced by Chinese or Western breeds in this study. We also verified the theoretical genomic composition of KWH at the molecular level in structure analyses. To our knowledge, this is the first genomic study to investigate the genomic characteristics of KWH and KCC.

Geum-Won dynasty is the era which totalized the every medical attainments of before Song dynasty and appeared some medical practioners who found new medical theory based upon this, and is important time for various developments of the oriental medical theory. At this time of the era, the representative practioners are called the four noted physician of Geum-Won dynasty. Jang Won-So who influenced the formation of the theory of the four noted physician of Geum-Won dynasty, originated new theory by joining the theory of 「Nae-Gyung」 with his own medical experience. The results can be summarized as follows after studying his life and idea of medicine. 1. Jang Won-So, courtesy name is Gyeol-Go, came from Yeog-Joo and it is unknown that when he was born and dead, but he lived in 11C. At 27, after failed in a Jin-Sa examination, he started medical study, and widely spreaded his medical art by healing the Yoo Wan-So's Sang-Han disease. 2. There are many Jang Won-So's writings, such as 「Eui-Hag-Gye-Won」 which is the condensation of his idea of medicine, 「Jin-Joo-Nang」 which is greatly contributed to development of Herbology, 「Jang-Boo-Pyo-Bon-Han-Yeol-Heol-Sil-Yong-Yag-Sig」 which is the sample of Jang-Boo-Byun-Jeung-Lon-Chi, and 「Yag-Joo-Nan-Gyung」 「Gyeol-Go-Ga-Jin」 「Gyeol-Go-Joo-Sug-Hwa-Mag-Myeol」 「Gyeol-Go-Bon-Cho」 「San-Yog-Bo-Sang-Bang」 which are known do not existing. 3. Jang Won-So's study about Jang-Boo-Byun-Jeung was influenced by 「Nae-Gyung」 「Jung-Jang-Gyung」 「So-A-Yag-Jeung-Jig-Gyeol」 etc. and outline by Han-Yel-Heo-Sil and the change and prognosis of the state of disease can be decided by Saeng-Sa-Yeong-Soon, so he contribute to development of Jang-Boo-Byun-Jeung-Lon-Chi of posterity. 4. Jang Won-So succeeded and develope the theory of the herbs of Oh-Jang-Go-Yog-Bo-Sa and about Ki-Mi-Seung-Gang-Boo-Chim etc. appeared on 「Nae-Gyung」, especially invented such as Kwi-Gyung-Lon, In-Gyeung-Bo-Sa-Seol, Jang Boo-Pyo-Bon-Yag-Sig and he enriched the content of pharmacological theory, so he motivated various development of herbalogical theory. 5. Jang Won-So's idea of On-Yang-Bi-Wi directly influence Lee Go's assertion of Bi-Wi-Lon, idea of Go-Geum-I-Gue-Seol presented theological basis of posterior medical practioners formation of prescription, so the way of drug usage greatly developed. 6. Jang Won-So's theory of the Jang-Boo-Byun-Jeung and herbology directly influenced to Lee Go, Wnag Ho-Go, Na Chen-Ik, Jang Byeok etc. so he became the father of Yeog-Soo class and indirectly influenced to Seol Gi, Jo Hen-Ga, Jang Gae-Bin, Lee Jung-Jae etc. of Myeng dynasty, so the On-Bo class has been formed. Like this, because, his idea of medicine developed at various aspect and greatly influenced to posterity, Lee Si-Jin said "Since the emergency of 「Nae-Gyung」, Jang Won-So is the only man who greatly enhance medical principle." so it is clear that this is not unfounded expression at all.

The effects of the Platonic ideas in the Procedures of the Modern Astronomy Birth Im, Jin-Yong So far the study of the effects of the Platonic ideas in the procedures of the modern astronomy birth has been superficial. The purpose of this study is to understand the effects of the Platonic ideas on the modern astronomy. But it is not concerned here with mathematical parts. Only what I wish to show in this study is the context of the thinking about the universe from the ancient Greek Ages to the terminal Renaissance. The Platonic ideas on the universe are more geometrical and harmonic than any other ideas. The characteristics of the Platonic ideas assimilated with Christianity in the Middle Ages. But those ideas took a position against the Aristotle`s ideas which had filled the role of the standard of the studies in the Middle Ages. The rebirth of the Platonic ideas in the Middle Ages was not original, that is to say Neo-Platonism. Because it dealed with more various parts, The Neo-Platonism was different from the original Platonic ideas. The Neo-Platonism expelled the Aristotle`s theories from the astronomical region. Therefore The Neo-Platonism commuted the non-geometrical standpoint into the geometrical standpoint in the interpretation of the universe. The Neo-Platonism inspired the ideas for the interpretation of the universe in Copernicus and Kepler. Specially the geometrical methods was very important and necessary for constructing the model of the solar system and the universe. The Neo-Platonic books provided the ideas(a geometry, musical chords, a notion of anima mundi, a notion of the infinite universe, etc) for creating the heliocentric system with the Renaissance astronomers. Thus the Platonism played a key functional role in the birth of the modern astronomy.

[연구목적] 본 연구는 재무분석가의 낙관주의 동기 유인이 예측 walkdown에 미치는 영향을 인지심리적 측면에서 검증하고 예측어려움이 높을수록 재무분석가의 낙관주의 동기유인이 예측 walkdown을 보다 강화하는지를 분석하였다. [연구방법] 이를 위해 재무분석가의 낙관주의 동기 유인과 예측어려움과 관련된 국내외 선행연구에 관한 문헌을 바탕으로 실증분석에 필요한 가설을 설정하였다. 가설 검증에 사용된 표본은 2011년부터 2016년까지 유가증권 시장의 상장기업 중 820개의 기업-연도표본이다. 재무분석가 이익예측자료와 재무자료는 Kis-Value에서 수집하였다. 수집된 자료를 바탕으로 Bradshaw et al.(2016)가 제시한 연구모형에 대한 회귀분석을 실시하였다. [연구결과] 본 연구의 분석결과는 첫째, 재무분석가의 낙관주의 동기 유인이 클수록 예측walkdown이 커지는 것으로 나타났다. 둘째, 예측어려움이 높을수록 재무분석가의 낙관주의 동기 유인이 예측walkdown을 강화하는 것으로 나타났다. 이는 재무분석가의 지향성 있는 결론에 대한 낙관주의 동기 유인이 클수록 매출액과 영업이익의 walkdown이 커지며, 이 과정에서 예측어려움이 조절작용을 하고 있음을 의미한다. [연구의 시사점] 본 연구는 낙관적 예측 편의가 존재하는 재무분석가의 보고서를 이용하는 시장참여자들이 합리적 판단을 할 수 있는 근거를 제공하고 재무분석가의 낙관적 예측편의에서 파생되는 시장의 부정적인 영향을 사전에 차단할 수 있는 정책수립의 근거를 제공하는데 시사점을 준다. [Purpose] This study examines the pattern of analysts’ forecasts within a fiscal year, which begins with optimism and declines as the earnings announcement date approaches, and also does that one factors, forecasting difficulty, interact with analysts’ incentives for optimism to induce cross-sectional variation in the steepness of forecast walkdown. [Methodology] As follows are univariate t-test and multivariate regressions results from a sample of 820 firm-years listed in Korea Exchange between 2011 and 2016. [Findings] The general association between analysts’ incentives for optimism and forecast walkdown is supported by empirical evidence. In addition, it is supported that as difficulty is higher, forecast walkdown becomes steeper. [Implications] This result means that analysts begin with optimism to react to motivation for a directional conclusion at the beginning of the year, adjust downward their forecast to react to motivation for accuracy as the earnings announcement date approaches. In addition, this means forecasting difficulty is in the highest at longer forecast horizons, it declines with the release of information during the year. Then, based on Kunda’s(1990) work, the biased accessing of information to support optimistic forecasts declines, leading to a forecast walkdown.

Background and Purposes: Over the past three decades, numerous studies performed in Korea have reported that job stress is a determinant risk factor for chronic diseases and work disability. Every society has its own culture and occupational climate particular to their organizations, and hence experiences different occupational stress. An occupational stress measurement tool therefore needs to be developed to estimate it objectively. The purpose of this study is to develop and standardize the Korean Occupational Stress Scale (KOSS) which is considered to be unique and specific occupational stressors in Korean employees. Subjects and Methods: Data were obtained from the National Study for Development and Standardization of Occupational Stress (NSDSOS Project: 2002-2004). A total of 12,631 employees from a nationwide sample proportional to the Korean Standard Industrial Classification and the Korean Standard Occupational Classification were administered. The KOSS was developed for 2 years (2002-2004). In the first year, we collected 255 items from the most popular job stress measurement tools such as JCQ, ERI, NIOSH and OSI, and 44 items derived from the a qualitative study (depth interview). Forty-three items of KOSS, in the second year, were retained for use in the final version of the KOSS by using Delphi and factor analysis. Items were scored using conventional 1-2-3-4 Likert scores for the response categories. Results: We developed eight subscales by using factor analysis and validation process: physical environment (3 items), job demand (8 items), insufficient job control (5 items), interpersonal conflict (4 items), job insecurity (6 items), organizational system (7 items), lack of reward (6 items), and occupational climate (4 items). Together they explained 50.0% of total variance. Internal consistency alpha scores were ranged from 0.51 to 0.82. Twenty-four items of the short form of the KOSS (KOSS-SF) were also developed to estimate job stress in the work setting. Because the levels of the subscales of occupational stress were gender dependent, gender-specific standard norms for both the 43-item full version and the 24-item short form using a quartile for the subscales of KOSS were presented. Conclusion: The results of this study suggest that KOSS might be an appropriate measurement scale to estimate occupational stress of Korean employees. Further and more detailed study needs to be conducted to improve the validity of this scale.

Objectives : One of the objectives of this study is to estimate the prevalence rates of psychiatric diagnoses in the combined populations of psychiatric hospitals, psychiatric nursing facilities and homeless asylums using the Korean version of the Composite International Diagnostic Interview (K-CIDI), which is a comprehensive and fully standardized interview schedule to assess psychiatric disorders for diagnosis. The Other objective is to compare with previously studied prevalence rates of Psy-chiatric diagnoses using the results of this study. Methods : The study subjects, aged from 181o 64 years, were randomly selected from 64,582 institutionalized population of psychiatric hospitals, Psychiatric nursing facilities and homeless asylums as of 30, June, 2001. Twelve trained interviewers administered the K-CIDI to the selected respondents. A total of 1,875 respondents (male 1,194, female 681) completed the interview. Results : The lifetime and one year prevalences of any diagnosis excluding nicotine dependence · withdrawal, anxiety disorder, eating disorder, somatoform disorder were 88.2% (male 88.1%, female 88.3%), and 65.8% (male 62.7%, female 73.7%), respectively. The lifetime and one year prevalences of schizophrenia and other psychotic disorders were 78.5% (male 75.3%, female 83.7%), and 56.8% (male 51.9%, female 64.8%), respectively. The lifetime and one year prevalences of alcohol use disorder (dependence/abuse) were 26.7% (male 37.9%, female 8.3%), and 8.7% (male 12.8%, female 2.1%), respectively. The lifetime and one year prevalences of mood disorder were 18.1% (male 13.5%, female 25.8%), and 10.4% (male 7.2%,female 16.9%), respectively. The lifetime and one year prevalences of schizophrenia and other psychotic disorders were comparable with the 2001 community survey by 1.19% to 1.32%, and 0.51% to 0.61%, respectively. The lifetime and one year prevalences of schizophrenia were also comparable by 0.16% to 0.28%, and 0.16% to 0.25%, respectively. There were no significant changes of prevalence rates when correction were applied to other psychiatric diagnosis. Conclusion : The results of this study could be used for evaluating the distribution of psychiatric diagnoses in mental health related facilities and for planning mental health policies.
