This is a brief review and discussion for present status and prospects of quality evaluation in medicinal plants as oriental medicine materials (OMM). Quality in medicinal plants could be defined as the combination of origin, external appearance, effectiveness and safety, and be evaluated by plant taxonomic, morphological, physiochemical and biological methods. For high-quality improvement and standardization of OMM, medicinal plants should be produced through using proper species or good variety and standard cultivation method in suitable cultivation area. Standardizing of quality means to meet with minimum qualifying criteria of OMM in the market while improving of quality to be over standard quality of medicinal piano in production. For making new high quality and standardized products, we need to keep standard field plants, standard OMM, standard plant specimen, and standard compounds. Researchers and administration have to study and propose the quality factors and their evaluating techniques and criteria, so high-quality and standardized produce of medicinal plane could be produced and distributed under the control of the relevant regulations, and would be contributed to increasing of national health.

Background: Communication is important for the elderly to maintain existing social relationships while creating new relationships based on good communication skills to lessen psychological and emotional distress and lead a healthy life in advanced age. Aims: This study identifies the difference between the social network-based quality of communication life and the overall quality of life in the elderly and how much the quality of communication life affects the overall quality of life. Methods: This research includes a survey of the elderly aged 65 and over living in small cities of South Korea. Data sets of 201 elderly were analyzed. Results: This study found a significant correlation between the quality of communication life and the overall quality of life. Religion also influences the elderly's quality of communication life. The elderly's quality of communication life has 40% explanatory power of the overall quality of life. Conclusion: Consequently, senior citizens' quality of life will be improved through the enhanced quality of communication in addition to financial and health conditions by participating in various community activities similar to those provided by religion to increase opportunities for communication.

A model for obtaining optimal resetting period and optimal target value of the process quality level is proposed when the quality characteristic is subject to a linear shift in mean. Different sales conditions are considered where good items can he sold at a regular price and bad items at a discounted one. Some numerical examples are also given.

Since degraded region of input image can cause false minutiae which lead to decrease identification performance, use minutiae belong to only good quality to ensure true minutiae. This paper suggests image quality measuring method with respect to local and global orientation of ridges. In order to verify a suggested method, PDFs of quality indices derived by local and global feature are computed and then, classifying each image block using Bayesian decision theory.

Recently towel cloth has a good prospect as sports wear and out fashion wear. So we will discuss correlational effects between towel cloth quality and it's physical properties. In order to investigate the effect of pile length on the stiffness and absorption of the towel cloth, some experiments have been carried out, and then analyzed by the correlation coefficient.

A rectifying inspection plan is considered for the case of destructive testing. Screening inspection for rejected lots is performed by some nondestructive testing which is prone to misclassification errors. Apparent defectives found in the screening process is replaced with apparent good items. The plan provides LTPD protection on each individual lot while the sum of the cost of testing and the cost due to producer's risk at process average quality is minimized. A brief discussion on average outgoing quality is also given.

본 연구는 창업가의 관련 기업 근무경험이 기업의 성장 가능성과 생존율을 높이는 '질 좋은 창업'에 미치는 영향을 확인하는 탐색적 사례 연구이다. 자원기반이론 관점에서 관련기업 경험을 통한 인적자본의 축적과 창업기회의 획득, 핵심경영자원의 확보를 '질 좋은 창업'의 요소로 보았으며, 벤처캐피탈인 'K벤처스'가 투자한 16개 모바일 게임/서비스 기업의 창업가를 대상으로 연구를 진행하였다. 연구 결과 16개 기업 27명의 기업가 모두가 창업 이전 관련 기업 근무경험을 보유하고 있었다. 이들은 관련기업 근무경험을 통해 기술능력, 관리능력, 사업영역의 지식, 창업동기 등 창업가의 인적자본을 축적하였으며, 이를 바탕으로 정보탐색, 기회인식, 기회추구 및 활용으로 창업을 실행하였다. 이러한 'K벤처스'의 투자 기준과 사례는 창업가의 직장경험과 인적자본이 벤처캐피탈의 투자결정에 긍정적인 영향을 미친다는 이전의 결과를 지지한다. 또한 심층연구를 수행 한 2개 기업의 사례는 관련기업 근무경험을 통해 축적한 창업가의 인적자본이 창업기회 획득과 벤처캐피탈 투자유치를 통한 핵심경영자원 확보를 촉진시켜 '질 좋은 창업'에 긍정적인 영향을 미침을 확인하였다. 본 연구는 인터넷/모바일 기업을 대상으로 진행된 탐색적 사례연구이며, 향후 본 내용의 일반화를 위한 실증연구가 추가되어야 할 것이다.

본 연구는 2009년 5월과 9월 두 차례에 걸쳐 보청천 유역의 5개 지점에서 어류상의 분포와 물리적 서식지를 조사함으로써 수행되었다. 생물통합지수인 IBI (Index of Biological Integrity) 모델은 우리나라 하천의 특성에 맞게 수정 보완하여 총 8개 메트릭 시스템으로 구성하였으며, 물리적 서식지 평가는 11개의 다변수 메트릭 모델을 이용하였다. 이화학적 수질 분석은 2005년부터 2009년까지의 환경부 수질 측정망 자료를 통해 8가지 수질 항목을 평가하는 것으로 이루어졌다. 어류의 종 조성을 분석해보면 내성종이면서 잡식종인 피라미가 약 24.3%로 가장 우점하였으며, 조사지점 중 총 4곳에서 외래종인 배스(약 1.2%)가 발견되었고, B5에서는 보호종인 감돌고기와 꾸구리가 채집되었다. 보청천 유역의 1, 2차 조사 결과 생물통합지수는 평균 28로 B등급의 양호상태(Good)로 나타났으며, B1, B4, B5가 양호상태(Good), B2와 B3는 보통상태(Fair)로 나타났다. 물리적서식지평가(QHEI)는 평균 152로 양호상태임이 확인되었으며, 공사중인 B5를 제외하고 하류로 갈수록 증가하는 경향을 보였다. 이화학적 수질 자료의 분석 결과, 평균 BOD는 지난 5년간의 보청천 유역 5개 지점에서 하천수질환경 기준(환경정책기본법)에 의거할 때 모두 Ia (매우 좋음) 등급으로 나타났다. 영양염류(TN, TP)와 부유물질(SS)의 값은 하천주변의 토지이용도에 따라 비점오염원의 영향이 달라져 지점별로 약간의 변이 폭을 보였다.

This study investigated the correlations between nutrient intake and dietary attitudes in Korean school dietitians. A total of 493 school dietitians working in the Kangwon and Kyungnam areas participated in this study. The subjects were classified as the good group(33.5%), fair group(36.9%) and bad group(29.6%) based on dietary attitude score. The results were as follows. The average intake of energy, calcium, and iron were lower than the Korean RDA and average CPF ratio of energy intake was 64 : 17 : 19. The percent RDAs of nutrient intake of energy, calcium, iron and vitamin B$_1$were lower in the bad group than those in the fair group and good groups(p < 0.001). The mean adequacy ratio(MAR), an index of overall dietary quality, were different among the three groups(p < 0.001), the highest was 0.96 in the good group, the lowest was 0.88 in the bad group. The index of nutritional quality(INQ) was significantly higher in the good group than the other groups. The nutrient intakes were positively correlated with dietary attitudes(p < 0.01). The nutrient intakes, INQ, NAR and MAR were significantly increased as the dietary attitude score increased.
