  • This study was made to investigate the ultrastructural changes of the hepatocyte of the maternal liver, and fetal liver by Actinomycin D in Wistar rats at the stage of pregnancy. Peritoneal injection of Actinomycin D to rats carried out gestation day 7 to 9 at the level of $15{\mu}g(11.5{\mu}g/100g$ body wt.), $20{\mu}g(15.8{\mu}g/100g$ body wt.) on each day. Treated animals with saline only were used for controls. Animals were sacrificed on day 15 of gestation. On electron microscopic examination, the hepatocytes of maternal liver given Actinomycin D $15{\mu}g$/ml had evidence of serious cellular damage, for example, hypertrophy of rough endoplasmic reticulum, loss in nucleolar osmiophilia, swelling of Golgi apparatus and change of mitochondrial structure. Maternal liver given Actinomycin D $20{\mu}g/ml$ shown similar changes to that of the $15{\mu}g/ml$ treated animals. But mitochondria of this group were not changed than that of $15{\mu}g/ml$ treated group. In the hepatocytes of fetal liver, changes were more pronounced. The drug produced alteration in nuclei and cytoplasm. The rough endoplasmic reticulum was swollen and there were ribosomes detachement. In addition, damages of mitochondria, Golgi apparatus were detected.

  • The purpose of this study was to analyze the current CRM situation in Korean apparel industry. Specifically, research purposes were 1) to examine the concepts and benefits of CRM, 2) to examine CRM strategies, 3) to analyze CRM system(i.e., customer relationship management service, customer segmentation criteria, DB management system), and 4) to analyze the potential problems and CRM adoption plan. The subjects for this research were thirty CRM managers in Korean apparel firms classified by the company type(woman's wear, man's wear, casual wear, children's wear, retailer) interviewed from December 2003 to March 1004. The results of this study were as follows: First, the concept of CRM represented the prime customer relationship, continuous consideration, and customer management system. The benefits of CRM reflected re-sales, improvement of profit share, and acquisition of customer's data base. Second, concerning the CRM strategies, most companies focused on persistent customer management through mileage program, membership cards and also implemented product strategies such as demand forecasting, customization based on customer data analysis. We also found that industry preferred to use pricing strategies, for example, segmentation of customer through discrepancies of price in which customers are provided by discount and gift voucher services. Regarding distribution strategy, channel diversification, localized service, and convenient delivery system were used. As promotion strategies, they chose celebrating customers' personal events and promoting cultural events and issuing coupons. Third, regarding CRM system, information service was the most frequently adopted, important and highly beneficial category. Also POS/web-POS, homepage were main sources of information. RFM is the mostly commonly used customer segmentation criteria. Fourth, potential problems in CRM adoption were lack of CRM knowledge and performance measurement of CRM. Future CRM adoption plan included CRM education and development of CRM performance measures.

  • Importance of the work-related musculoskeletal disorders (WMSDs) has been increasing in the hospital industry such as health care industry and financial industry. This study investigated in order to identify the factors like general, occupational and ergonomically characteristics of the subjects related to musculoskeletal disorders (MSDs) of physical therapists (PTs). Ergonomic tools of rapid upper limb assessment (RULA) were used for evaluation workload of the tasks. Prevalence of MSDs were 13 PTs (26.0%) for neck, 31 PTs (62.0%) for shoulder, 9 PTs (18.0%) for arm/elbow, 27 PTs (54.0%) for hand/wrist, 28 PTs (56.0%) for back, 14 PTs (28.0%) for leg/foot. The analysis of the rate of the pain intensity showed that 53.5% subjects experience moderate pain and 14.0% subjects experience severe pain. Factors which were general characteristics, for example, height, ergonomically characteristics such as 'Posture Score A' were related musculoskeletal subjective symptoms in logistic analysis (p<.05). Among physical therapists, action level of RULA were action level 2 (6.0%), action level 3 (52.0%), action level 4 (42.0%). Physical therapists were estimated one of the highest risk factor in this study. This study suggested that the need of preventive education and program for PTs (physical therapists). Comprehensive and systematic management plans should be established to include both ergonomic and sociopsychological aspects.

  • General, fast, and efficient stitching methods are presented for the synthesis of Fr$\acute{e}$chet-type dendrimers with linear units at a core, as a preliminary investigation for the synthesis of dendritic-linear-dendritic materials. The synthetic strategy involved an inexpensive, 1,3-dipolar, cycloaddition reaction between an alkyne and an azide in the presence of the Cu(I) species, which is known as the best example of click chemistry. The linear core building blocks, 1,7-octadiyne and 1,6-diazidohexane, were chosen to serve as the alkyne and azide functionalities for dendrimer growth via click reactions with the azide and alkyne-dendrons, respectively. These two building blocks were employed together with the azide- and alkyne-functionalized Fr$\acute{e}$chet-type dendrons in a convergent strategy to synthesize two kinds of Fr$\acute{e}$chet-type dendrimers with different linear core units. This comparative efficiency of the click methodology supports the fast and efficient synthesis of dendritic-linear-dendritic materials with the tailor made core unit.

  • 지난 반세기 동안 인간 심리에 대한 연구는 많은 연구 도구들의 창출을 가져왔다. 눈에 보이지 않는 심리 현상을 객관화하기 위한 노력의 일환으로 다양한 검사도구들이 개발되었고 이러한 흐름은 인간 심리에 대한 양화된 자료의 양산을 가져왔다. 그러나 인간 경험의 주관성과 세밀함을 고려해 보건데 개인의 독특한 경험 세계와 이를 해석하는 관점에 대한 연구가 병행되어야만 한다. 본 논문은 이런 맥락에서 인간의 심리를 탐구하는 도구로 사진을 제안하고, 사진의 연구도구 가능성을 타진해보았다. 스마트폰의 확산과 함께 파고든 사진 찍기 일상은 사진이라는 예술활동을 대중 친화적으로 만들었고, 만약 이러한 사진 찍는 활동이 인간의 심리를 탐구하는 연구도구로서의 기능을 충실히 수행한다면 인간에 대한 이해의 깊이와 넓이는 획기적인 전기를 맞이하게 될 것이다. 사진이 인간의 주관적인 경험과 해석을 얼마나 충실히 담아내는지를 검토하기 위하여 대학생 두 명의 우정에 대한 사진을 소개하였고 이를 바탕으로 사진의 연구도구 가능성을 피력하였다.
