Purpose: This quasi-experimental study was performed to investigate the effects of a health promotion program(HPP) on self-efficacy, healthy lifestyle and blood lipid profile in employees with hyperlipidemia. Methods: The subjects were forty-three employees who were diagnosed as having hyperlipidemia during routine health examination at two worksites in Seoul in 2001. Of the forty-three subjects, thirty were allocated to the experimental group and the remaining thirteen were allocated to the control group. Data were collected from September 24, 2001 to March 16, 2002. The HPP was applied to the experimental group for 11 weeks and included health education, diet counseling, watching videos, conference, and so on. The health education included information about exercise, smoking cessation, and abstinence from drinking alcohol and seven sessions of hyperlipidemia education. The experimental group was requested to keep a daily health promotion lifestyle diary. This diary was analyzed by a dietician and subjects were instructed based on the results. As for data analyses, wilcoxon signed rank test and wilcoxon rank sum test and x2-test were carried out using SAS program. Results: 1. Self-efficacy scores of the experimental group were significantly more increased than those of the control group (experimental: 5.86 10.80, control: -4.04 11.91, p=0.018). 2. Healthy lifestyle scores of the experimental group were significantly more increased than those of the control group (experimental: 0.19 0.26, control: -0.05 0.29, p=0.024). 3. Blood total cholesterol values of the experimental group were significantly more decreased than those of the control group (experimental: -13.07 30.10mg/dl, control: 10.00 26.57mg/dl, p=0.033). 4. Blood triglyceride values of the experimental group were significantly more decreased than those of the control group (experimental: -29.17 192.40mg/dl, control: 63.31 107.53mg/dl, p=0.050). Conclusion: These findings indicate that the HHP could be effective in improving self-efficacy, healthy lifestyle and blood HDL cholesterol and decreasing blood total cholesterol in employees with hyperlipidemia. Therefore, the HHP could be suggested as an effective nursing intervention for employees in the worksite by ultimately preventing cerebral and cardiac vessel complications related to hyperlipidemia.

본 연구는 갈비찜 제품의 품질을 개선하고자 SHS와 HPP 기술을 적용한 시료를 냉장온도(5, $10^{\circ}C$)에서 저장하면서 그 품질 변화를 살펴보았다. 기호도 조사를 통해 SHS 조리가 일반 조리에 비해 높은 기호도를 보였으며 특히 다즙성과 조직감(연한 정도)이 향상되는 것을 알 수 있었다. 이것은 조직감 측정 결과와 같은 경향으로 SHS 조리가 일반 조리에 비해 조직이 연해져 부드러운 조직감을 부여하는 것을 알 수 있었다. 또한 지방의 산화반응을 억제하며 총균수의 증가폭도 일반 조리구에 비해 적은 것을 확인할 수 있었으며 SHS-HHP 병행 처리 시 $5^{\circ}C$에서 15일간 저장하여도 검출한계 수준(<1 log CFU/g)으로 검출되었다. 또한 지방 산패도 값인 TBA 또한 SHS-HHP병행 처리군이 일반 조리에 비해 낮은 값을 보여 안전성을 확보할 수 있을 것으로 사료된다. 식육의 신선도를 나타내는 VBN은 간장 양념으로 인해 높은 값을 보였지만 육제품의 특성상 VBN 함량만으로 신선도 정도를 판단하기는 어려울 것으로 사료된다. 이상의 결과로 기존의 갈비찜 제품에 SHS 기술과 HPP 기술의 적용으로 제품의 품질 향상을 통한 기호도 상승과 유통기간 연장효과를 어느 정도 기대할 수 있는 것으로 생각되었다.

This fundamental studies on for the productivity improvement and laborsaving of purse seine fishery. Given the difficulty posed from the distortion of net shape caused by the external forces, such as tide, at the time of shooting and pursing, we set the 4 steps of 0, 2, 4 and 6cm/sec in flow velocity in the flume tank for the experiment in order to examine those characteristics. We used two model seines designed on the scale of 1 to 180 based on the power block seine, which is the mackerel purse seine generally used in the near sea of Jeju Island and triplex seine, which is the mackerel purse seine of one boat system fishing expected in the future, for the experiment, and interpreted the characteristics of several motion in water, such as the shape of seine, the change in tension and area during pursing and its the analysis results are as follows. Though the experiment could be conducted up to 6cm/sec of flow velocity that was defined, the experiment could not go on because of the severe distortion in the seine at the flow velocity in excess of 6cm/sec. As for the depth of leadline and reduction rate of side area of seine when the pursing is connected, P seine turned out to be slightly higher than T seine, and the hauling speed and reduction rate of upper area of seine were found similar to each other. The correlation between the hauling time (Ht) and depth of lead line (Dhp, Dht) of P seine and T seine can be expressed by the equation, that is, Dhp=(0.99Pt-7.63)Pt+69.01, Dht=(1.03Pt-7.73)Pt+66.74. The correlation between the hauling time and hauling velocity (Hpp, Hpt) can be expressed by the equation, that is, $Hpp=-0.06Ht^2+0.88Ht+0.78,\;Hpt=-0.05Ht^2+0.81Ht+0.98$ here, Pt is pursing time. And the correlation between the pursing time and the reduction rate of side area (sArp, sArt) can be expressed by the equation, that is, $sArp=-0.48Pt^2+14.79Pt-16.74,\;sArt=-0.45Pt^2+14.56Pt-16.48$. The reduction rate of upper area of seine (tArp, tArt) can be expressed by the equation, that is, $tArp=0.34Pt^2-0.66Pt-0.74,\;tArt=0.34Pt^2-0.27Pt-1.80$. In addition, the correlation between the pursing time and tension of purse line (Tep, Tet) can be expressed by the equation, that is, $Tep=2.79Pt^2+2.26Pt-0.60,\;Tet=2.14Pt^2+8.08Pt-27.50$.

The developments of science education until the middle of the 20th century were often driven by personal ideas and achievements of some influential individual scientists (e.g. T. H. Huxley, H. E. Armstrong. L. Hogben, J. Conant). while that of the 2nd half of the 20th century can be characterized as collective efforts through various research grou ps of science educators (e.g. PSSC, HPP, Nuffield, SATIS). In this respect, John Tyndall(1820-1894), a physicist of the Victorian England best known as Tyndall's Effect, can be considered as one of the great scientists who made a big influence on science teaching and the popularization of science before science secured its place in school curricula. Tyndall worked as a research scientist at the Royal Institution of London, where various lectures and demonstrations of physical sciences were regularly performed for general public, and he was particularly famous for his fascinating physics demonstrations. In this study, we summarize his activities and achievements as a teacher as well as a popularizer of physics, illustrate some of his famous demonstrations and his ideas concerning physics teaching and discuss their implications to today's physics education.

The PCR primer set JW21-JW22 of Weiss et al. (19), which was reported to amplify a 139-bp fragment of the l6S rRNA gene of Helicobacter pylori, has been recently used for the detection of H. pylori in clinical specimens. However, when we applied JW21-JW22 PCR to other members of the genus Helicobacter and unrelated microorganisms, all of these bacteria produced a 139-bp PCR product. Therefore, we designed a novel primer set, HPU185-HPL826, which produced a 642-bp amplicon of the l6S rRNA gene of H. pylori. Then we further examined the specificity of the novel PCR assay using Southern blot hybridization with an internal probe, HPP225. The PCR assay described in this study was shown to be highly sensitive and specific only to the H. pylori 16S rRNA gene sequences.

With an active structural involvement in spiral case structure (SCS) that is always the design and research focus of hydroelectric power plant (HPP), the compressible membrane sandwiched between steel spiral case and surrounding reinforced concrete was often assumed to be linear elastic material in conventional design analysis of SCS. Unfortunately considerable previous studies have proved that the foam material serving as membrane exhibits essentially nonlinear mechanical behavior. In order to clarify the effect of membrane (foam) material's nonlinear stress-strain behavior on SCS, this work performed a case study on SCS with a compressible membrane using the ABAQUS code after a sound calibration of the employed constitutive model describing foam material. In view of the successful capture of fitted stress-strain curve of test by the FEM program, we recommend an application and dissemination of the simulation technique employed in this work for membrane material description to structural designers of SCS. Even more important, the case study argues that taking into account the nonlinear stress-strain response of membrane material in loading process is definitely essential. However, we hold it unnecessary to consider the membrane material's hysteresis and additionally, employment of nonlinear elastic model for membrane material description is adequate to the structural design of SCS. Understanding and accepting these concepts will help to analyze and predict the structural performance of SCS more accurately in design effort.
