Background: Ginseng (Panax ginseng Meyer) is an important medicinal herbs in Asia. However, ginsengvarieties are less developed. Method: To developed ginseng varieties, a pure line selection method was applied in this study. Results: Gumpoong was testing of 4-yr-old specimens in 2002, the proportions of the below-groundroots that were rusty colored for Gumpoong was 1.29 in Daejeon and 1.45 in Eumseong, whereas theproportions for its yellow berry variant were 2.60 and 2.45 in the two regions, respectively. Thus theGumpoong was resistant to root rust. Sunpoong has a high yielding property. Its average root weight is70.6 g for 6-yr-old roots. Its yield is 2.9 kg/1.62m2 and the rate of heaven- and earth-grade product is20.9%, which is very high compared to 9.4% for Yunpoong. Sunone is resistance to root rot and thesurvival rate of 4-yr-old roots was 44.4% in 1997, whereas that of the violet-stem variant landrace was21.7%. Sunhyang has content of arginyl-fructosyl-glucose (AFG), which produces the unique scent of redginseng, is 95.1 mmol/g and greater than the 30.8 mmol/g of Chunpoong in 6-yr-old plants. Sunun andCheongsun are being nurtured to protect genetic resources. Conclusion: Developed ginsneg varieties will be used as the basis for the protection of genetic resourcesand breeding. Jang-Ho Lee

전직 관료 영입이 기업성과에 미치는 영향: 산업에 따른 효과성 분석

박준호(Park, Jun-Ho),이장우(Lee, Jang-Woo) 한국경영교육학회 2021 경영교육연구 Vol.36 No.1

[연구목적] 지금껏 전직 관료 영입과 기업성과 간의 관계를 다룬 다양한 연구가 진행되어 왔다. 하지만, 선행연구들은 서로 다른 연구방법과 연구대상으로 인해 혼재된 결과를 보임으로써 지속적인 의문을 증폭시키고 있다. 이에 본 연구는 두 가지 산업을 비교 분석함으로써 전직 관료 영입과 기업성과 간의 보다 명확한 관계를 관찰하고자 하였다. [연구방법] 연구를 위해 1998년부터 2017년까지 총20년의 연구기간을 선정하고 의약품 및 의료기기 제조업 189개 기업과 화학산업에 포함된 화학물질 및 화학제품 제조업 136개 기업의 데이터를 수집하여 연구를 진행하였다. [연구결과] 연구결과, 취약한 제도적 환경으로 평가되는 의료산업에서는 전직 관료 영입이 기업성과에 정(+)의 영향을 미치는 것으로 관찰되었으며 비교적 안정적인 제도 환경으로 평가되는 화학산업에서 전직 관료 영입이 기업성과에 유의미한 관계가 없는 것으로 관찰되었다. [연구의 시사점] 본 연구는 그동안 전직 관료 영입과 기업성과 간의 혼재된 연구결과를 설명하는데 기여할 수 있을 것으로 예상된다. 특히, 기업이 속해 있는 산업의 제도적 환경에 따라 전직 관료 영입이 기업성과에 미치는 영향이 다를 수 있음을 시사하고 있다. [Purpose] So far, various studies have been conducted on the relationship between recruiting former bureaucrats board and corporate performance. However, prior studies have amplified persistent questions by showing mixed results from different methods and subjects. Thus, the study sought to observe a clearer relationship between the two major variables through comparative analysis of two different industries. [Methodology] To fulfill the aim of the research, we covered the corporate performances for 20 years from 1998 to 2017. The data were collected from 189 pharmaceutical/medical companies, and another 136 chemical related companies. [Findings] In the medical industry, which is regarded as a unstable institutional environment, the recruitment of former bureaucrats has been observed to have a positive effect on corporate performance, and in the chemical industry, which is considered to be a relatively stable institutional environment, the recruitment of former officials has no significant relationship to corporate performance. [Implications] The study is expected to contribute to explaining the mixed results of the research between recruiting former bureaucrats and corporate performance. In particular, it suggests that the impact of recruiting former bureaucrats on corporate performance may vary depending on the environment of the industry to which the company belongs.

The incidence of coexisting hyperparathyroidism and empty sella syndrome is rare and the etiology and incidence of their coexistence is not known. The association of hyperparathyroidism and the empty sella syndrome may be related to multiple endocrine neoplasia (MEN) syndrome due to a genetic disorder. We experienced a rare case of hyperparathyroidism presenting as acute pancreatitis combined with empty sella. We report here a 37-year old female who manifested epigastric pain because of acute pancreatitis. She had hypercalcemia due to parathyroid adenoma. A pituitary gland was not visible in the sella turcica on MRI scans. On genetic analysis, she did not show a mutation of the MENIN gene. Empty sella is thought to be a coincidental finding with hyperparathyroidism.

The object of this study is to survey water quality of reservoirsin in Asan city. We also suggest some countmeasures for environmental preservation toward sustainable urban development of Asan city. We analyze water qualities (pH, DO, COD, SS, T-P, T-N and Chlorophyll-a) of reservoirs. The level of water quality of small reservoirs is in the range of level Ⅳ-Ⅴ higher than the level Ⅲ established by the Ministry of Environment. Especially, water quality of Sinchang, Youngin and Shinchung reservoirs is worser than that of other reservoirs. Water quality of Asan and Sapkyo lake is the range of level Ⅳ-Ⅴ. As the levels of T-P and T-N are level Ⅳ and level Ⅴ, respectively, eutrophication might be progressed. Reservoirs in Asan city were already serious polluted by inflow of wastewater from residents, animal husbandries and industries. Recently, Metropolitan Area Development Planning(MADP) for Asan bay-area was suggested by the Ministry of Construction. According to this plan, industrialization and urbanization of Asan area will rapidly progress. If sewage and wastewater treatment facilitiesare not provided, water quality of reservoirs in Asan city will be worse. In order to prevent of environment pollution, first, the impact of industrialization and urbanization of Asan area on the environment should be considered at the beginning of MADP. Second, total effluent regulation of water pollution, air pollution and soil wastes, based on the self-purification of the Asan city environment, should be enforced.

이(lice)는 인체에 기생하면서 그들의 생활을 영위하고 여러 가지 질병을 전파하는 매개체로서 널리 알려져 온절족동물의 일종이다. 과거에는 인체에 발생하는 많은 질병의 매개체가 되었으나 그동안 의식주의 개선,공중 및 개인위생의 향상으로 최근에는 인체기생의 빈도가 많이 줄었으며 따라서 이에 의한 질병의 발생도 많이 감소하였다. 더욱이 안검을 침범한 음모이의 국내에 보고된 증례는 1976년 백 등이 보고한 2례, 1977년 신 등이 보고한 1례, 1996년 이 등이 보고한 1례, 1997년 김 등의 1례로 총 5례 뿐이다. 저자들은 세극등과 광학현미경 검사로 음모이에 의한 안검염으로 확진한후,세극등을 이용한 물리적 제거와 항생제 안약 및 연고의 도포를 하며 총 4주간 추적관찰을 하였으며 이 기간동안추가적인 음모이의 성충이나 충란의 발견이 없는 좋은 치료 결과를 경헝하였기에 이를 보고하는 바이다. We have experienced with a rare case of blepharitis caused by pubic lice, which was confirmed by slit-lamp and light microscopic examinations and resulted with a good outcome with appropriate treatment as follows. A two year old male child complained of foreign body sensations bilaterally, and an itching sensation at both upper and lower eyelids for 2 months. He was diagnosed with blepharitis caused by pubic lice after observation of adult louse and nits on slit-lamp examination. The treatment was accomplished by mechanical removal of the lices and nits by forceps and antibiotic eyedrops and ointment were applied to both eyes. The morphologic evaluation was performed with slit-lamp and light microscopy. The follow-up interval was a week for next one month and no louse or nit was found under slit-lamp examination. So we decided that the pubic lice was completely removed.

A study has been performed on the characteristics of rural and urban surface ozone concentration for the period of March 1992 to February 1993. The monitoring station of rural ozone is located at Kosan, Cheju and other urban monitoring stations are located at Seoul, Pusan and Kwangju. Rural's and urban's ozone data exhibit a distinct features in many ways. First, annual mean of rural ozone concentration is very high(42 ppbv) but urban's are very low(10~15 ppbv). Second, rural ozone data shows a seasonal variation with it's maximum in spring, and minimum in summer, but urban's show a seasonal variation with it's maximum in spring, and minimum in winter. Third, diurnal variation of rural data is very small but that of urban's are very large. Fourth, monthly mean of daily minimum of rural data is not low and shows a large seasonal variation, but those of urban's data are extremely low(<3 ppbv) and have no seasonal variations.

장준호,강동묵,고상백,김정원,조병만,이수일 大韓産業醫學會 2004 대한직업환경의학회지 Vol.16 No.2

목적 : 남성 금속제품 조립 작업자들의 피로에 영향을 미치는 작업관련요인을 파악하고자 한다. 방법 : 작업자의 일반적 특성 및 작업관련 특성, 육체적 부하, 직무 스트레스 등을 조사 항목으로 하여 자동차 부품 조립업 1개소(476명), 자동차 엔진 조립업 1개소(610명), 대형 선박 엔진 조립업 1개소(454명)의 작업자(1,540명)를 대상으로 수거된 설문지 중 부실하게 응답한 38부를 제외한 1,136부(총연구대상의 73.8%)를 분석하였고, 피로도와의 연관성을 다중선형회귀분석으로 살펴보았다. 조사는 자기 기입식 설문지를 사용하였다. 육체적 부하를 측정하기 위해서는 Borg의 scale이 사용되었다. 격무 스트레스를 측정하기 위해서는 Karasek의 Job content questionnaire가 사용되었다. 피로의 측정은 전반적 피로도(sum of fatigue), 일상생활 기능장애(daily dysfunctioning), 상황적 피로(situational fatigue), 피로점수의 총합(sum of fatigue)으로 구성되어 있는 다면적 피로척도를 사용하였다. 피로점수의 분포는 본 연구에 응답한 피로점수의 총합을 사분위수로 나누어서 4등급으로 나누었다. 결과 : 피로점수의 분포는 피로점수의 총합을 사분위수로 나누었을 때, 0≤1등급≤73, 74≤2등급≤82, 83≤3등급≤93, 94≤4등급≤133이었다. 다중선형회귀분석에서 피로점수의 총합과 유의한 관계를 보인 경우는 주간근무, 긴 주당 노동시간, 높은 육체적 부하, 높은 직무요구도, 낮은 직무자율성, 낮은 상사의 지지 등이었고, 전반적 피로도와 유의한 관계를 보인 경우는 주간근무, 높은 육체적 부하, 높은 직무요구도, 낮은 직무자율성, 낮은 상사의 지지 등이었다. 일상생활 기능장애와 유의한 관계를 보인 경우는 주간근무, 긴 주당 노동시간, 높은 육체적 부하, 낮은 직무자율성 등이었다. 상황적 피로와 유의한 관계를 보인 경우는 높은 연령, 주간근무, 긴 주당 노동시간, 낮은 직무자율성 등이었다. 결론 : 피로관련 요인은 긴 주당노동시간, 높은 직무요구도, 높은 육체적 부하, 낮은 직무자율성, 낮은 상사의 지지로 생각된다. Objectives: To find work related factors affecting perceived fatigue among male metal product assemblers. Methods: The study subjects were metal product assemblers from three metal product companies (476 car parts assemblers, 610 car engine assemblers, 454 ship engine assemblers). From the total of 1,540 subjects, 1,136 (73.8%) were included and 38 respondents with insufficient replies were excluded. Associations between fatigue score and other variables (general characteristics, job related factors, workload, job stresses) were investigated in terms of the concept of multidimensional fatigue construct by self administered questionnaire. Using MFS (Multidimensional Fatigue Scale), JCQ (Job Content Questionnaire), and Borg's scale, we estimated the fatigue, job stress, and workload, respectively. Fatigue score was estimated by 'sum of fatigue' in MFS. Associations were tested by linear regression analysis using SAS v.8.0. Results: In this study, the fatigue related factors were older age, longer working hours per week, higher workload, higher job demand, lower decision latitude, and lower supervisor support. Conclusions: Prolonged working hours, higher workload, higher job demand, poor supervisor support and lower decision latitude were fatigue related factors among the male metal product assemblers of this study.
