당근(Daucus carota L. var. sativa)은 세계적으로 널리 이용되는 작물 중 이며, 영양학적으로도 중요한 작물이다. 하지만, 종자 표피세포에서 생성되는 종자모는 발아를 억제하고 흡수를 저해하여 육묘에 어려움을 야기한다. 이러한 어려움을 타파하기 위해 당근 종자는 기계적인 제모작업을 거쳐 상품화 되고 있다. 이 과정에서 생산상의 여러 가지 단점들이 발생하며, 이를 보완하기 위해 단모종자 당근 품종의 육종이 필요하다. 따라서 본 연구는 단모종자 표현형 CT-ATR 615 OP 666-13개체와 장모종자 표현형 CT-ATR 615 OP 671-9개체 및 단모종자 표현형 CT-SMR 616 OP 659-1 개체와 장모종자 표현형 CT-SMR 616 OP 677-14개체 등 두 조합의 종자 cDNA library를 작성 후 EST 염기서열의 비교분석을 통해 당근 종자모 형질관련 연구에 이용하고자 하였다. 첫째로 EST 염기서열의 BlastX 결과를 바탕으로 각각의 EST를 FunCat 기능별 category로 분류하였다. 그 결과 Metabolism category와 protein folding 및 stabilization, protein binding, C-compound binding category에서 2조합 모두 동일한 유의적인 차이를 확인하였다. 두 번째로 EST 염기서열의 GO data를 바탕으로 seed trichome differentiation 및 cellulose biosynthetic process에 관련된 EST를 선발하였다. 이러한 FunCat category에서의 차이점과 GO data 분석을 통해 확인된 후보 EST 들이 당근 종자모 형성에 많은 영향을 미치는 것으로 생각된다. 마지막으로 분석된 개체 별 EST 염기서열을 바탕으로 33개의 SNP site, 741개의 SSR site를 확인하였다. 확인된 SNP 및 SSR site는 당근 종자모 형성에 관련된 분자마커 개발에 이용할 수 있음은 물론 당근의 여러 형질에 대한 연구에 활용 가능할 것으로 기대된다.

기업연상(corporate association)이 제품 평가(product responses)에 어떻게 영향을 미치는 가에 대한 연구가 부진하다는 Brown and Dacin(1997)의 문제 제기가 있은 후, 기업연상이 제품 판단에 미치는 영향과 과정에 대한 조절변수와 매개변수들을 파악하려는 연구가 진행되어 왔다. 본 연구에서는 기업연상의 두가지 유형인 CA(corporate ability) 연상과 CSR(corporate social responsibility) 연상이 성능과 재무위험에 미치는 영향력과 그 영향력을 조절하는 변수들을 조사하였다. 분석 결과에 의하면, 주효과(main effects)에 있어서는, 가설에서 기대한 바와 같이 CA 연상이 성능위험과 재무위험에 유의한 영향력을 갖는 것으로 나타난 반면, CSR 연상은 성능위험과 재무위험에 대해 유의한 영향력을 갖지 않는 것으로 나타났다. 조절변수로 인한 상호작용효과와 관련해서는, CA 연상이 성능위험과 재무위험에 미치는 주효과에 대해 제품범주 지식과 관여는 각각 유의한 조절효과를 나타내었다. 하지만, CSR 연상이 성능위험과 재무위험에 미치는 주효과에 대해서는 제품범주 지식과 관여의 조절효과는 나타나지 않았다. 이러한 연구 결과를 통하여 제품의 기능적인 속성에 대한 정보가 부족한 제품에 대해 소비자가 지각하는 위험을 감소시키기 위하여, 기업은 CSR 연상보다는 CA 연상에 대해 강조할 필요가 있다는 결론을 내리게 되었다.

1. Objectives: We report a series of 4 obesity cases who responded well to the weight-loss therapy based on the Taeeum Sasang constitutional therapy. 2. Methods: In treating 4 obese patients who were constitutionally typed as the Taeeum type, Case 1 and Case 2 fell into the category of the Lung Dry-Cold symptomatology, Case 3 into the Dry-Heat symptomatology, and Case 4 into the Exterior-Interior Combined symptomatology. Each patient was given Sasang medication according to protocol: Taeeumjowi-tang (Taiyintiaowei-tang) to Case 1 and Case 2, Cheongpyesagan-tang (Qingfeixiegan-tang) to Case 3, and Seunggijowi-tang (Chengqitiaowei-tang) to Case 4. On each visit to the clinic (7-21 times in total), the patients were checked on their general condition and change in body weight. 3. Results and Conclusions: All patients showed improvements in their general condition and a satisfactory decrease in weight (Case 1 showed a decrease of 12.7 kg in 84 days, Case 2 a decrease of 8.9 kg in 39 days, Case 3 a decrease of 33 kg in 250 days, and Case 4 a decrease of 29.3 kg in 155 days). Treating obesity based on Taeeum constitutional therapy was found to be effective for weight loss and general improvement of health. The sustained effects of the therapy should be checked during the following visits. The obesity treatment protocol suggested in this investigation should be explored and verified in future studies.

Purpose: The purpose of this study was to explore the health-illness transition of patients with Young-Onset Parkinson's Disease (YOPD). Methods: From June to November 2011, 17 patients with YOPD who visited a neurologic clinic in a tertiary hospital participated in the study. Data were collected through in-depth interviews and analyzed using the grounded theory of Strauss and Corbin. Results: The core category of the participants' health-illness transition emerged as 'reshaping identity following uncontrollable changes'. The participants' health-illness transition process consisted of six phases in sequence: ego withdrawal, loss of role, frustration, change of thought, modification of life tract, and second life. Although most participants proceeded through the six phases chronologically, some returned to the frustration phase and then took up the remaining phases. Conclusion: The study results provide an in-depth understanding of health-illness transition experiences in the participants. These findings suggest a need to develop appropriate nursing intervention strategies according to the different phases in the health-illness transition of patients with YOPD.

Purpose: The purpose of this study was to understand the adjustment process of middle-aged people in Korea with hemiplegia after a stroke. Method: For this study, the grounded theory method was utilized. Results: After constant comparative analysis, the core category emerged as 'rebuilding the body which was ruined'. In addition, the causal conditions were 'restriction of physical function', and 'loss of roles'. The adjustment process consisted of the 'facing reality phase', 'overcoming depression phase', 'overcoming physical limits phase' and 'reestablishing roles phase' The main strategies in the facing reality phase were 'holding on to a glimmer of hope', 'getting away from the harsh reality' and 'facing up to the reality'. The main strategies in the overcoming depression phase were 'soothing oneself', 'Self-introspection' and 'restoring self-esteem'. In addition, the main strategies in the self-initiative overcoming physical limits phase was 'discovering personal strategies and striving to recover'. The main strategies in the reestablishing roles phase were 'reestablishing a parents' role', 'reestablishing a spouse's role' and 'reestablishing social roles'. Conclusion: In conclusion, even though many middle aged stroke patients remained in the depression phase, most of them who overcame depression strived to conquer physical limits on their own initiative.

Purpose: The research was conducted to investigate the experience of maternal role attainment of mothers of premature infants admitted in NICU and to conceptualize the phenomena. Method: The grounded theory method was utilized for data collection and analysis. 8 mothers of premature infants were selected and in-depth interview was performed. Paradigm model was utilized for data analysis and presentation. Result: The central category was 'unstable maternal identity'. The properties of the core phenomena was 'ambivalent feeling to baby' 'negative emotion' 'commitment to baby'. The loss of control due to premature delivery was the causal condition. contextual condition was the 'perceived threats' due to severity of the premature infant and uncerainty of the baby's life. The mother's health status, economic status, and familial and social support was recognized as intervening conditions during the process of maternal role attainment. The strategic action/interactions were emotion-focused coping, reappraisal of the situation, problem-focused coping, and information seeking. The consequence was the maternal role attainment with competence and expectation. Conclusion: The process of maternal role attainment was affected by threats due to severity of the baby and intervening factors and interaction strategy. Further research is recommended to develop adequate intervention method during the process of maternal role attainment.

Purpose: This study was to investigate the factors influencing on the quality of life (QOL) among herniation of nucleus pulposus (HNP) patients caused by occupational accidents. Method: 203 patients of HNP were recruited. 106 patients were occupationally injured workers who benefited from workmen's compensation scheme (PWCS group), and 43 patients were non-occupationally injured workers benefiting from national health insurance (PNHI group). Questions of QOL items were used by Korean version of SBQOL (SmithKlein Beecham's Qality of Life). Result: The quality of life of PWCS group measured by SBQOL was significantly lower than that of PNHI group. In PWCS group, SBQOL was significantly lower in patients with 40s of their age, 5 years or longer of treatment duration, no expectation of return to work, no expectation of recovering subject's health, and with loss of employment than rest of the patients in each category. Expectations of recovering subject's health showed to be affect factors on QOL both the PWCS and PNHI groups. Conclusion: It suggested that betterment of expectation of recovering patient's health and an administrative system for returning to work of the occupationally injured HNP patients during treatment be necessary for improvement of their quality of life.
