The leaf beetle, Chrysolina aurichalcea (Coleoptera: Chysomelidae), is a pest damaging plants of Compositae. In order to understand the genetic diversity and geographic variation we sequenced a portion of mitochondrial COI gene (658 bp) and complete nuclear internal transcribed spacer 2 (ITS2) of the species collected from seven Korean localities. A total of 17 haplotypes (CACOI01~CACOI17), with the maximum sequence divergence of 3.04% (20 bp) were obtained from COI gene sequence, whereas 16 sequence types (ITS2CA01~ITS2CA16), with the maximum sequence divergence of 2.013% (9 bp) were obtained from ITS2, indicating substantially larger sequence divergence in COI gene sequence. Phylogenetically, the COI gene provided two haplotype groups with a high nodal support (≥87%), whereas ITS2 provided only one sequence type group with a high nodal support (≥92%). The result of COI gene sequence may suggest the presence of historical biogeographic barriers that bolstered genetic subdivision in the species. Different grouping pattern between COI gene and ITS2 sequences were interpreted in terms of recent dispersal, reflected in the ITS2 sequence. Finding of unique haplotypes and sequence types only from Beakryeng-Islet population was interpreted as an intact remnant of ancient polymorphism. As more samples are analyzed using further hyper-variable marker, further fruitful inference on the geographic contour of the species might be available.

박은경,홍지원 한국의류학회 2003 한국의류학회지 Vol.27 No.11

The purpose of this study was to develop customized necktie design according to Korean adult male's body characteristics. For this purpose, experimentations of visual sensory evaluation on visual stimuli which show a man's wearing various neckties were carried out. The subjects were students(n=130) majoring in fashion and design related area and experts(n=6). The data were analyzed by ANOVA, duncan test, pearson's correlation coefficient, cross tabulation using spss pc^(+) program. Also statistic of Korean adult men's body measurements(1997) were analyzed and used to decide appropriate necktie length according to the customer's various height. The results were as follows: First, there were significant difference in visual sensibility on the stimuli showing 1) relative location of belt and necktie. 2) neckties with various length using golden ratio to the experimental model's height. Therefore, the need of producing neckties with different length according to customer's various height were verified. Second, neckties with three different length(140㎝, 145㎝, 151㎝) were suggested for the groups of 160㎝ height, 170㎝ height, 180㎝ height according to Korean adult male's body characteristics and aspect of production.

박창권,김태형,정원지 國立 昌原大學校 産業技術硏究所 2002 産技硏論文集 Vol.16 No.-

At present most mechanical design engineers use the techniques that perform shape modeling, force analysis and DMU(Digital Mok-Up). This kind of design methods shorten the time of manufacturing prototypes and have a merit that decreases development cost. But a hydrauric system has inconvenience that engineers have to modify, and complement whenever needed, because simulation-based approaches are not ubiquitous compared to the case of general mechanical parts. This paper presents a case study of efficient application to hydrauric system for designing VRCS(Valve Remote Control System) using a Hycdraulic system design and analysis software.

Background : The goal of this study was to establish the QA items and guidelines for preventing and improving of safety management. Therefore we investigated the nurses' recognition and knowledge of the safety and risk procedures and policies, and the agreement between the nurses beliefs on the degree of miportance of those procedures and policies, with actual implementation in hospitals. Method : The subjects of this study were 201 nurses who participated in a program called continuing education for nurses, which held in December, 1993. Result : The results of this study were as follows: 1. Among 18 types of hospital risks, the items that scored highest or the need of closer attention in safety management was the needle stick, medication errors, falling, and bed sores. 2. In most questions of the 18 incidences, the nurses showed that the estimated result would have positive signs except for hospital infections, burns, and bed sores. 3. Even though the survey shows that incidences and types of occurences varies according to the person's age and the time of incident, they mostly occur between midnight to 6AM. Falls and bed sores can be seen more in the elderly. Medication errors, hospital infections and bums are frequently found between the ages of one through twenty. 4. There was a higher mean score for recognizing the importance of those items than the importance of implementing them. Conclusion : In summary, nurses did perceive the need of safety management but the hospital policy for proper safety management was not established. So we recommended that the hospital administration would undertake an early detection and proper management system for hospital precautions, based on QA items & guidelines presented in this study.

Sasang constitutional medicine is Korea 's creative medical science, that has attracted public attention. But for lake of indices in objectifying constitutions, there are difficulties for most of health professionals in approaching Sasang medicine. The purpose of this study was to compare the results of clinical diagnostic data according to the type of Sasang constitution. Method: The subjects were 95 examinees who had a general health check-up at A hospital. The instrument used for this study were Questionnaires of Sasang Constitution Class Ⅱ(QSCCⅡ) program for personal computer develop by Kim Sun Ho et al. Result: The distribution of constitution of the subjects were the So-eum 46.7%, the Tae-eum 36.9% and the So-yang 46.7%. The level of body composition-related indices(body, weight, obesity) of the Tae-eum were significantly higher than those of other constitutions. In heart-related indices, systolic BP were the highest in he Tae-eum. In liver-related indices, the level of triglyceride, SGPT were significantly higher in the Tae-eum. But the hematologic indices and lung-related indices were not showed significantly difference among any constitution. Conclusion: The results of this study showed that there were significant difference of clinical diagnostic data according to Sasang constitutions, especially in the Tae-eum. So, to understand the human nature of nursing clients, nurses need to apply the oriental based medical theory, like Sasang constitution, to the discipline of nursing.

Background : Vivax malaria had spread rapidly in areas adjacent to the Demilitarized Zone to reach more than 4,000 cases in 2000 in the Republic of Korea (ROK). After year 2000, annual cases decreased rapidly to reach less than 1,000 cases in 2004. However, the number increased again since 2005. Epidemiological characteristics of vivax malaria in the ROK are different before and after 2000. This article was aimed to evaluate the current status of malaria elimination project in the ROK for providing suggestions for its improvement. Materials and Methods : We analyzed the total reported malaria cases during 2005 to 2007 and reviewed the record on the malaria eradication project performed by the authorizations including the Korea Center for Disease Control and Prevention. Results : During 2005 to 2007, 45% of all the vivax malaria occurred in patients living in the non-prevalent areas; the interval between first symptom onset and diagnosis was longer in the non-prevalent areas compared to that in the prevalent areas. Education and publicity on malaria has not been properly performed in the non-prevalent areas. The military didn't take part in the control of the malaria infected discharged soldiers, most of whom might have been infected with malaria during their military service. Conclusion : For the efficient control of malaria and thus improving the effectiveness of the elimination project education and publicity on malaria in the non-prevalent areas should be strengthened and cooperation between private and military sector regarding the ex-soldiers infected with malaria is essential, In addition, there should be bilateral communication among malaria-related teams within the Korea Centers for Disease Control and Prevention and also among all the malaria-related sectors. Furthermore a common database on malaria patients and vector mosquitoes should be formed to grant access to all the malaria-related sectors, Improvement on report and surveillance system is also necessary.

Fatigue is one of the most common complaints of cancer patients. In this study, we analyzed the change of fatigue level and general symptoms as time go by, so that, we could explain more on the mechanism and chance of fatigue in relation with treatment, and explore the influencing factors. Method: The subjects of this study were 50 GI cancer patients who have visited the cancer center of A hospital in Suwon. We measured fatigue by using the Revised Piper Fatigue Scale(RPFS) at the time of starting and finishing induction chemotherapy, and starting the 2nd cycle of chemotherapy. Results: 1) The fatigue score was 2.81, 3.73, and 3.82 in a 10 point scale at the time of starting and finishing induction chemotherapy, and starting the 2nd chemotherapy, respectively. This means fatigue persisted until after the treatment. 2) Fifty two percent of participants complained of some kinds of symptoms when starting the treatment, and the proportion increased up to 92% when finishing the treatment. 3) Fatigue scores were significantly high in patients with fatigue-related symptoms than for patients without those symptoms. 4) Fatigue scores showed significant differences according to patients' general characteristics such as age, educational level, economic status, occupation, diagnosis, hematocrit, weight, and amount of sleepy. Conclusion: We have to develop intervention strategies to reduce fatigue in cancer patients in the consideration of influencing factors.

영남지방 벼-보리 이모작답에서 가장 널리 시행되고 있는 보릿짚 처리방법인 소각이 대기환경에 미치는 영향을 소각시 발생하는 온난화가스, 대기오염가스 및 분진발생량을 중심으로 살펴보았다. 보릿짚 소각시 온난화가스 발생량은 CO₂376.8, CH₄ 1.56, N₂O 0.05 kg/10a 로서 CO₂의 발생량이 가장 많았으며, 대기 오염가스 중에는 유기물의 불완전 연소시 배출되는 CO발생량이 28.8 kg/10a로서 가장 많았다. 그 외 SO₂ H₂S, NH₃, NO등의 질소 및 황 함유 유해가스도 소량 발생되었고 발생된 PM 10 분진의 대부분은 인체에 미치는 영향이 PM 10보다 큰 PM 2.5로 이루어져 있었다. 또한 수확시기가 빠르거나 수분함량이 높은 보릿짚일수록 온난화가스 및 대기오염 가스의 발생량이 증가하고 소각 연기내 PM 10 분진중 PM 2.5의 미세분진 비중이 높았다. 수확적기로 알려진 출수 40일 이후의 보릿짚은 출수 후 40일된 보릿짚 소각시 발생하는 대기오염가스 발생량과 큰 차이가 없었다. This study was carried out to determine impacts of burning of barley straw produced from rice-barley double cropping paddy field on air quality by investigating emissions of greenhouse gases (CO₂, CH₄ and N₂O), air pollution gases (CO, SO₂, H₂S, NH₃ and NO) and particulate matters (PM 10 and PM 2.5). When the barley straw at a rate of 4.5 t/ha was burned at open status, the emitted GHGs amounts were CO₂ 376.8 kg/10a, CH₄ 1.56 and N₂O 0.06. The amount of CO emission was the largest among air pollution gases. These results showed that the range of 45~55% of total C in barley straw was emitted as CO₂-C, followed by CO-C (6.4~5.9%) and CH₄-C (0.5~0.7%). As far as moisture content in barley straw is concerned, the higher moisture content that the barley straw contains, the larger amount of air pollution gases and the higher portion of PM 2.5 in PM 10 were emitted when it burned. In case of harvesting time of barley straw, emission amounts of greenhouse, air pollution gases and PM 2.5 portion in PM 10 had tendency to increase when earlier harvested barley straw was burned.

Strut-and-tie models can illustrate very well the internal flow of forces in structural concrete and thereby, provide valuable assistance to the designer who is striving for an appropriate and functional conceptual design. After some introductory statements this will be demonstrated by dimensioning and detailing the support region of concrete box girders. In this paper it will be shown how a strut-and-tie model for the different arrangement of transverse diaphragm are developed and how in the model the interaction between the longitudinal and cross sections must be considered.
