This experiment was conducted to investigatd the variation of some apearance chemical components at National Honam Agricultural Experiment Station in Korea. the treatements consisted of five transplating times, form May 5 to July 5 at 15-day interval , and six cultivars ; two early-maturing, two mid-maturing and two latematuring cultivars. The results showed that the variatio of grain appearance such as length-wide ratio was not significantly different in early -maturing cultivars, but mid-and late-maturing cultivars made slightly a round shape of grain in case of early transplanting. Percentage of complete grain was found to be high at transplanting of MAy 20 inearly-maturing cultivars and on June 5 in mid-and late-maturing ones. PERcentage of existed embryo after milling showed high at early transplanting of May 5 for early -maturing cultivars, and at the late transplanting of June 5 in early and late maturing one. The chemical components of rice grain showed high in protein , lipid,ash and amylose content inthe earlier transplanting, and also revealed high in carbohydrates, magnesium and potassium in the later transplanting of all cultivars.

In January 2016, Korea began rice exporting to China from six domestic Rice Processing Complexes (RPC). The appearance characteristics and quality of medium-short grain milled rice between the exported Korean rice was compared with Wuchang rice, which is known as high quality in Heilongjiang province in China, and the imported rice from Japan and Taiwan in Chinese circulating marketing. The 1000-grain weight of exported rice is 22.4g, which is similar to that of Chinese Wuchang rice, but it tended to be heavier than that of Japanese and Taiwanese. The rice type is round in exporting Korean, Japanese, and Taiwanese rice while Chinese Wuchang rice is thin and long with 2.5. The head rice rate of export rice was 93.3 ~ 98.4%, which was 95.8% on average, which was higher than that of Chinese Wuchang rice, and similar to that of Japanese, and Taiwanese. The protein content of the export rice was 5.2 ~ 6.2%, which was 5.8% on average, similar to that of Chinese Wuchang rice, Japanese and Taiwanese. Amylose content was 18.5% of the exported rice, which was lower than that of Chinese Wuchang rice and slightly higher than that of Japanese and Taiwanese. The whiteness of the exported Korean rice was 35.6 on the average, lower than 41.8 of Chinese Wuchang rice, and lower than that of Japanese and Taiwanese. The purity of rice variety being exported ranged from 87.5 to 100.0%, which was 96.5% on average. This was much higher than that of Chinese Wuchang rice, while the Japanese and Taiwan rices were similar. The sensory test of rice by the experts, cooked rice of the exported was evaluated to be good for all items such as taste, sticky glutinous, and texture compared to Chinese Wuchang rice.

하기용,최윤희,정진일,노광일,고재권,이재길,김정곤 韓國作物學會 2006 Korean journal of crop science Vol.51 No.1S

벼 품종 간 이화학적 특성 및 취반특성에 관여하는 요인을 구명하여 취반특성별 품종 군을 분류하고 밥맛이 좋은 품종의 취반특성 요인을 구명하여 고품질 품종이 갖는 미질 요인을 파악함으로써 고품질 품종육성 및 품종선발의 지표로 삼고자 실험을 수행하였는바 그 결과는 다음과 같다. 1. 백도는 대야벼, 호평벼, 고시히까리가 높았고 현미의 경도는 일품벼가 낮았으며 신동진벼가 가장 높았다. 2. 호화점도 특성중 호평벼와 고시히까리는 대야, 호안벼에 비하여 강하점도가 높고 치반점도, 응집점도가 낮았으며 특히 고시히까리는 최고점도, 강하점도가 매우 높은 반면 치반점도와 응집점도가 낮았다. 반면 일품, 운광벼는 다른 품종보다 강하점도는 낮고 치반점도가 높았다. 3. 품종별 물성 요인에서는 밥알의 경도는 호평벼가 다른 품종보다 유의적으로 낮았고 응집성이 높았다 반면 점성 및 부착성, 균형도는 고시히까리가 높았다. 4. 밥맛을 간접적으로 평가할 수 있는 기계적 식미치 검정에서는 대야벼 호안벼가 낮고 일품벼, 운광벼가 높았다. We analyzed factors which related with rice quality at seven varieties. The whiteness of Daeyabyeo, Hopyeongbyeo and Koshihikari were higher than those of other rice varieties. In the hardness of brown rice, Ilpumbyeo was the lowest, and Sindongjinbyeo was the highest among varieties. The hardness cooked rice of Hopyeongbyeo were significantly low, and cohesiveness of those were significantly high. but adhesiveness, viscosity and gumminess of Ko-shihikari was high than other cooked rice varieties. The palatability of Daeyabyeo and Hopyeongbyeo were higher than those of Ilpunbyeo and Ungwangbyeo. Varieties which were known as having good palatability were higher in the breakdown, while setback and consistency were low. In those varieties, factors of upper were correlated with palatability, so this were supposed to determine palatability.

THE RELATIONSHIP BETWEEN HRM PRACTICES AND ORGANIZATIONAL PERFORMANCE IN THE PUBLIC SECTOR: FOCUSING ON MEDIATING ROLES OF WORK ATTITUDES

고재권,AARON SMITH-WALTER 한국행정학회 2013 International Review of Public Administration Vol.18 No.3

Using the 2011 Federal Employee Viewpoint Survey (FEVS), this study analyzes HRM practices based on high-performance work systems (HPWS) in federal-level public sector organizations, and the effects on employees' work attitudes and organizational performance. The authors argue that HRM practices contribute to increased organizational commitment, organizational citizenship behavior, and job involvement, and that these work attitudes are positively related to organizational performance. Evidence is presented to suggest that work attitudes mediate relationships between HRM practices and organizational performance, with certain HRM practices being associated with improved work attitudes. Implications for future research are also discussed.

행정에서의 공공성에 대한 재고 - 공공서비스의 전달체계를 중심으로 -

고재권 한국거버넌스학회 2014 한국거버넌스학회보 Vol.21 No.2

최근 다양한 학문 영역에서 공공성에 대한 많은 논의들이 이루어져왔다. 특히 행정학에서도 신공공관리론의 대두에 따른 행정에서의 공공성에 대한 논의가 많은 관심을 받아왔다. 그러나 공공성은 다양한 개념을 내포하고 있으며 복잡한 내용을 포함한다. 본 연구에서는 공공성에 대한 기존의 논의를 살펴보고 공공성에 대한 개념을 제시하는데 일차적인 목적을 둔다. 그리고 본 연구에서 제시한 공공성에 대한 개념을 통하여 최근 대두된 행정에서의 공공성의 위기라는 문제를 이해해보고자 한다. 마지막으로 공공서비스의 전달체계를 바탕으로 행정에서의 공공성이 어떻게 이해될 수 있는지 살펴보고자 한다. Recently, there has been a lot of discussion about publicness in various academic fields. In particular, public administration has experienced an animated discussion about publicness because of problems of New Public Management. However, publicness has various concepts and a broad range of contents, which leads to unconsented definition for publicness in public administration. Therefore, this study aims to define publicness with regard to formal and substantial aspects. Specifically, this study uses public service delivery modes to understand publicness.

고재권,JaeKwonKo 한국자원식물학회 1997 한국자원식물학회지 Vol.10 No.4

벼 생태형별 조만성 차이가 뚜렷한 조생종으로 오대벼와 신운봉벼, 중생종으로 청명벼와 장안벼, 만생종으로 동진벼와 만금벼 등 6개 품종을 공시하여 호남노업시험장 수도포장에서 1993년 5월 5일부터 15일 간격으로 5회에 걸쳐 작기이동을 시켜 이들의 작물학적 특성을 비교, 검토하였던 바는 다음과 같다. 1. 작기이동에 따른 출수기변이는 조생종은 6월 5일 이앙 이후에는 파종에서 출수까지 일수가 89~90일에 출수되어 변이폭이 적었으며 모든 품종에서 이앙시기가 늦어질수록 출수일수는 짧아졌다. 2. 일수입수, 등숙비율 및 천립중은 조생종은 5월 5일 이앙구, 중.만생종은 6월 5일 이앙구에서 많거나 무거운 경향이었다. 3. 수량성은 조생종은 5월 20일 이앙구에서, 중.만생종은 6월 5일 이앙구에서 최대수량을 나타내었다. 그러나 이앙시기가 늦어졌을 때 조생종과 만생종의 차는 6월 20일 이앙구에서는 10a당 44~77kg, 7월 5일 이앙구에서는 10a당 26~30kg로 만생조이 더 증수됨을 알 수 있었다. A study was carried out to investigate the variation of heading date and related yield components at Honam Agricultural Experiment Station in Korea. The treatments were consisted of five transplanting time: from May 5 to July 5 at 15-day intervals, and six cultivars: two early-maturing, two mid-maturing and two late-maturing cultivars. The results showed that variation of heading at different transplanting time was not significant at transplanting after June 5 in early-maturing cultivars, and days of heading from seeding for all tested cultivars were shorter in later transplanting times. The yield components such as numher of spikelcts, percentage of ripened grain and 1.000 grain weight were found to he great on May 5 in early-maturing cultivars and on June 5 in mid-and late-maturing cultivars. Yield was maximized at transplanting of May 20 in early maturing and on June 5 in mid-and late-maturing cultivars. When transplanting time was late, the yield difference hetween early maturing cultivars and late nldtunng ones showed 44 to 77kg/10a in the transplanting of June 20, and 26~30kg/10a in the transplanting of July 5 indicating that the late-maturing cultivars take more advantage than early-maturing ones.

벼의 품종별 이앙시기가 미질 특성에 미치는 영향 IV. 지경위치별 미립의 외관특성과 미질특성의 변화

고재권 한국자원식물학회 1998 한국자원식물학회지 Vol.11 No.2

This experiment was conducted to investigated the characteristics of grain appearance, chemical components. gelatinization, and palatability of cooked rice on each rachis branches as harvested from the transplanting plot of May 20 and June 5 in each two varieties of early-maturing and late-maturing types. In evaluation of rachis branches, the percentage of ripended grain and 1,000 grain weight were found to be high and heavy at upper part of panicle. The factors influencing palatability such as maximum viscosity and breakdown as gelatinization characteristics, and hardness, apringiness, cohesiveness and chewiness as texture characteristics of cooked rice were found to be high at upper part of panicle , indicating the parlability was favored more at upper part than at lower part of panicle due to the genetics and physiological metabolism of rice plants.
