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.

This study examines the preceding researches on the policy entrepreneurs at home and abroad and after discussing the policy entrepreneurs, analyzes the flow of the revision process of the partial revised bill(hereinafter referred to as Chun Doo-hwan Collection Law) of the confiscation special law about public official crime by administration using the multiple streams framework model, and this researcher attempts to analyze the activities of how the policy entrepreneur among diverse policy actors who plays an important role in opening policy window influenced the revision process in the process of enacting the partial revised bill of the confiscation special law about public official crime. And how the policy window of the partial revised bill of the confiscation special law about public official crime that was not opened in the previous administrations came to be opened in the Park Geun-hye administration is analyzed. The results of this study confirmed that in the previous administrations the policy entrepreneur to open the policy window did not appear but in the Park Geun-hye administration President Park Geun-hye played the role of the policy entrepreneur, producing Chun Doo-hwan 본 연구는 정책기업가 대한 국내외 선행연구를 검토하고, 정책 기업가에 대한 심도있는 논의를 하고자 하였다. 또한 공무원 범죄에 관한 몰수 특례법 일부 개정안(이하 전두환 추징법)의 정책과정을 다중흐름모형을 이용하여 각 정권별로 흐름을 분석하였다. 공무원 범죄에 관한 몰수 특례법 일부 개정안의 정책결정 과정에서, 정책기업가 (policy entrepreneur)가 어떻게 중요한 영향을 미칠 수 있는 활동을 할 수 있었는지에 대한 분석을 시도하고자 한다. 그리고 이전 정권에서는 열리지 않던 ‘공무원 범죄에 관한 몰수 특례법’ 일부 개정안에 대한 정책의 창이 현재 박근혜 정부에 와서는 어떻게 열리게 되었는지에 대한 분석을 한다. 연구결과, 이전의 정권들에서는 정책의 창을 여는 정책기업가가 나타나지 않았고, 박근혜 정부에서는 박근혜 대통령이 정책기업가의 역할을 하여 전두환 추징법이 산출되었다는 것을 확인하였다.

1920년대 한국 시론의 미적 지향성

김동근(Kim, Dong-geun) 원광대학교 인문학연구소 2013 열린정신 인문학연구 Vol.13 No.3

This thesis concerning the aesthetic directivity of 1920s poetics by relationship with formation logic of Korean Modern poetry. Concretely, this explores the terms of literary modernity that Korean Poetical circles were faced in 1920s, in other words it explores individual poet"s aesthetic directivity through the relation of Traditional-aesthetics and Symbol-aesthetics. Also, it examines the development process of Korean essay on Modern poetry based on mutual negotiation of Traditional-aesthetics and Symbol-aesthetics. First, Kim-Eok"s essay which navigates "a Refined Poetic form" as a new tradition is reinterpreted in terms of correlation between symbol and tradition. Second, in the case of Kim-Sowol, it focuses on the establishment of a new tradition called "Poetical Spirit" as a matrix of language. Third, Baek-Daejin"s essay is organized as the subject of combination of symbol and life. Fourth, the main point of Hwang-seokwoo"s essay is that he tried to establish ethics of life by some ideal things like the order of nature. In Korean Modern Poetical Circles, Traditional-aesthetics and Symbol-aesthetics are not mutually exclusive. In the process of Korean Modern poetry of 1920s securing autonomous region from the public spheres, they have formed a complementary and different directivity. This aspect is clearly contrasted to the point that the Korean essays on poetry of 1930s were developed forming a full-scale competition.

Background : For cultivation of varieties of ginseng, the pure line selection method, which is to select the best among those cultivated in farms for pedigree breeding, replicated yield trials and regional adaptation trials before registering as a new variety, is widely used. Although there are 25 registered varieties of ginseng in Korea, the quality of ginseng is declining together with the amount of harvest being decreased by 15 - 20% due to the heat injuries and diseases from the warming & abnormal climate. Thus, the needs for development of disaster-resistant varieties with better chances of surviving through high temperature, salts and disease are increasing. Therefore, this study is to cultivate disaster-resistant varieties among those selected for their disaster tolerance and salt tolerance through regional adaptation trials. Methods and Results : As a result of examining the growth characteristics of the selected 2 - 5 year old varieties used in the study, among the 5-year old crops, Goryeo 4 and Eumseong 5 showed superior growth in both above and below aerial parts, and among the 4-year old crops, Eumseong 11 and Cheonryang showed superior growth while the growth in the below aerial parts were satisfactory in the order of Cheonryang > Eumseong 10 > Eumseong 11 > Eumseong 9. Among the 3-year old crops, the most superior growth in both above and below aerial parts was observed in Eumseong 14 with the weight of the below aerial part, root diameter and taproot length at 13.8 g, 11.8 ㎝ and 6.2 ㎝ respectively. Among the 2-year old crops, Eumseong 10 showed the most superior growth in both above and below aerial parts. Conclusion : Based on the above results, Goryeo 4 and Eumseong 5 among the 5-year old crops, Eumseong 11 among the 4-year old crops, Eumseong 14 among the 3-year old crops and Eumseon 10 among the 2-year old crops showed the most superior growth among the selected varieties. The growth characteristics of both above and below aerial parts in each year will continuously be monitored.

본 연구는 친수성 용매가 함유되어 있는 3종의 단일병 접착제의 적용 시간을 증가시켰을 때, 건조 상아질에 대한 재습윤의 효과가 있는지를 미세인장 결합강도의 측정을 통해 알아보고자 시행하였다. 실험대상은 최근에 발거한 상하악의 대구치로, 교합면 1/3 부위의 치질을 치아 장축에 수직으로 절단하여 상아질을 노출 시킨 후, 32%인산 (Unietch, Bisco Inc., Schaumburg, IL, USA)으로 15초간 산부식 하고 수세하였다. 치아는 무작위로 S군 (Single Bond), O군 (One-Step), P군 (Prim & Bond NT)으로 분류하였고, 각 군은 다시 3군 (W: 상아질 표면의 남아있는 과잉의 물을 수분에 적신 거즈를 이용하여 제거한 후, 즉시 단일병 접착제를 적용하고 광중합, D: 30초간 건조 한 후 즉시 단일병 접착제를 적용하고 광중합, 30: 30초간 건조 한 후 단일병 접착제를 30초간 적용하고 광중합)으로 소 분류 하였다. 접착제 도포 후, 복합레진을 축조하고 접착계면이 1 ㎟가 되도록 절단 하여 각 군당 20개의 표본을 사용하여 미세인장 결합강도를 측정하였다. S군, O군의 30초 적용군 (S-30, O-30)은 건조군 (S-D, O-D)보다 높은 미세인장 결합강도를 보였으며, S-30군의 경우 S-D군보다 통계학적으로 유의성 있게 높았다 (P< 0.05). 하지만, P군의 30초 적용군 (P-30)은 건조군 (P-D)에 비해 미세인장 결합강도가 통계학적으로 유의성 있게 감소하였다 (P < 0.05). The purpose of this study was to evaluate the effect of increasing application time of single bottle adhesives (SBA) to microtensile bond strength (MTBS) of dried dentin. To expose the superficial dentin surfaces, human molars were sectioned perpendicular to the long axis of tooth. 32% phosphoric acid gels were applied for 15s and rinsed. The teeth were randomly assigned to 3 groups ; S group (Single Bond), O group (One-Step), P group (Prime & Bond NT). Each group was divided to 3 subgroups (W: dentin wipe with wet gauge and light cured immediately, D: dentin dried for 30s and light cured immediately, 30: dentin dried for 30s and light cured after applying SBA for 30s). Composite resin was built up on the dentin surface and sectioned to obtain 20 specimens with 1 ㎟ cross sectional area and the MTBS was measured. For Single Bond, the mean MTBS of S-W and S-30 group were higher than that of S-D group statistically (P < 0.05). For One-Step, the mean MTBS of O-D group was statistically lower than that O-W group (P < 0.05). For Prime & Bond NT, the mean MTBS of P-30 group was statistically lower than that of P-D group (P < 0.05).

칩브레이커 형상변수에 의한 칩유동각 예측

김동현,박승근,김경우 韓國工作機械學會 2000 한국생산제조학회지 Vol.9 No.2

In machining with cutting tool inserts having complex chip groove shape, the flow, curl and breaking patterns of the chip are different than in flat-face type inserts. In the present work, an effort is made to understand the three basic phe-nomena occurring in a chip since its formation in machining with groove type and pattern type inserts. These are the ini-tial chip flow, the subsequent development of up and side curl and the final chip breaking due to the development of tor-sional and bending stresses. In this paper, chip flow angle in a groove type and pattern type insert is analyzed based on a force ratio method, involving the feed and radial forces in flat-face type, groove type and pattern type inserts. The expres-sion for chip flow angle in groove type and pattern type inserts is also verified experimentally using high speed filming techniques.
