This study was carried out to provide information on the effect of nutrition education program for diabetic patients at the Guri City's Public Health Center. Subjects of this study were 31 persons(male 7, female 24) who attended all courses of "2002 Diabetes Education Class". They were indicated as the 'education group'(EG). Eating and living habits of EG were investigated before the education. EG's weight and blood glucose (post prandial 2 hours, PP2) were examined as well. EG's PP2 reduction was compared with a 'control group'(CG) who didn't join any course in that class. All of the subjects were non-insulin-dependent diabetes mellitus(NIDDM) patients. EG's average age was 62.4$\pm$8.8. Before taking the course, EG's PP2 was 251.5$\pm$29.6mg/dl, and body mass index(BMI) was 26.3$\pm$2.3 on average. Most of them were stressed out from their daily lives and usually had no exercise. Most people of EG ate meals rapidly and liked sweet and fatty foods. After the course of training, EG's weight and BMI before the training were not decreased significantly. However, all of the EG's PP2s, which were measured 4 times(before the meal at the special lunch session, after 2 hours at this meal, after 2 weeks and 4 weeks dietary assembly), were decreased in comparison with the PP2 which was checked prior to joining the training. EG's average PP2 was more reduced than CG's one. In addition, all groups' PP2s were decreased for 8 weeks. After all, this nutritional education at the public health center was effective in glycemic control for diabetes mellitus patients. Especially, when the dietary assembly as practical training was included in the educational process, the patient's dietary intake and PP2 was improved more effectively. Therefore, this study suggests that nutrition work at public health centers is necessary for the Health Promotion Policy.

It is generally accepted that the delivery of health care is undergoing many changes specially those related to acute, contagious disease care and to the increase of chronic illnesses which can not be cured but are controlable. The health care practitioner can not be soley responsible for the control of their clients' care. Because the clients will play a vital role in controlling their illnesses, long term participation by both the health care provider and the client is necessary. Since most individuals with hypertension do not experience signs or symptoms, the disease is difficult to detect and even when diagnosed, clients do not comply well with their hypertension regimens. The noncompliant client is at increased risk for compliants involving the heart, brain, kidney and other organs. In an effort to explore methods of increasing patient participation in and adherence to treatment programs for hypertension, the researcher used health contracting to promote self care. The research questions are; 1) Will the health contracting increase compliance in health behavior and reduce the blood pressure\ulcorner 2) If clients comply with their regimens will this reduce their blood pressure\ulcorner The research design utilized in this study was a quasi-experimental design. A purposive sample, was abtained from two churches in the 1. area, consisting of 64 clients with hypertension. The data was collected from the middle of January to the 1st of September 1985. Randomization was only of the two church groups into experimental and control groups. Compliance with health behavior related to the hypertensive regimen, blood pressure and body weight were measured, compared and analyzed. In the experimental group measurements were made 6 times; one month before the education program after education program when health contracting was done and 4 more times once a month for 4 months. In the control group measurements were made 3 times; one month before the education program after the education program, and once 4 months later. There was no health contracting. The data were analyzed by t-test, Pearson correlation and ANOVA according to purpose of the study. The result of this study may be summarized as follows: The result related to the hypothesis on the effect of health contracting are as follows: H$_1$; “The hypothesis that the experimental group, with a health contractual agreement will demonstrate increased compliance levels for health behavior than the control group” was supported(t＝-5.29, df＝62, p＝.000). H$_2$; “The hypothesis that the experimental group, with a health contractual agreement, will demonstrate a greater reduction in blood pressure than the control group” was supported (for systolic blood pressure t＝2.72, df＝62, p＝.009, for diastolic blood pressure t＝1.95, df＝62, p＝.050). H$_3$; The hypothesis that the greater the compliance of the client with health behavior the lower the client's blood pressure will be was partially supported (for systolic pressure r＝-.2981, p＝.008, for diastolic pressure r＝-.1720, p＝.087). From the examination of the results of this study it can be concluded that the interaction between the nurse and the client, contracting to define goals and reinforcing compliant behavior, leads to improved compliance with health care behaviors and thus to an increase in the effectiveness of nursing care. Further consideration need to be given to the inclusion of the concept of health contracting in primary nursing and to further research in this area.

Strawberry ($Fragaria{\times}ananassa$) is one of the most important and popular fruit crops in the world, and 'Sulhyang' is one of the principal cultivars cultivated in the Republic of Korea for the domestic market. The growth and flower induction in strawberry is the process which influences directly on fruit bearing and yield of this crop. In this study, effect of benzyladenine (BA), gibberellic acid ($GA_3$), and salicylic acid (SA) on growth and flower bud induction in strawberry 'Sulhyang' was investigated. The 3-week-old runner plants, grown in 21-cell propagation trays, were potted and cultivated in growth chambers with $25^{\circ}C/15^{\circ}C$ (day/night) temperatures, 70% relative humidity (RH), and light intensity of $300{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$ photosynthetic photon flux density (PPFD) provided by white light emitting diodes (LEDs). The runner plants were treated with one of three concentrations, 0 (control), 100, and $200mg{\cdot}L^{-1}$ of BA, $GA_3$, or SA solution. The chemicals were sprayed two times on leaves of runner plants at an interval of two weeks. After 9 weeks the results showed that the application of all chemicals caused reduction of root length and chlorophyll (SPAD) content as compared to the control. The lowest chlorophyll (SPAD) content was recorded in plants treated with $GA_3$. However, the treatment of $200mg{\cdot}L^{-1}$ $GA_3$ promoted leaf area, leaf fresh weight, and plant fresh weight. The greatest flower induction (85%) and number of inflorescences (4.3 inflorescences per plant) were observed in the treatment of $200mg{\cdot}L^{-1}\;SA$, followed by $100mg{\cdot}L^{-1}\;SA$. Overall, results suggest that foliar application of $GA_3$ solution could accelerate plant growth, while foliar application of SA solution could induce hastened flowering. Further studies may be needed to find out the relationship between $GA_3$ and SA solutions treated in a combination, and the molecular mechanism involved in those responses observed.

Objective: This study was conducted to investigate the effects of dietary probiotic blend and liquid feed program at different nutritional densities on growth performance, nutrient digestibility, fecal score of weaning piglets. Methods: A total of 120 weaning pigs with an initial body weight of 7.05±0.93 kg per pig (21 days of age) were randomly allocated into 1 of the following 8 dietary treatments (3 replicates per treatment with 5 pigs per replicate) in a 2×2×2 factorial arrangement (nutrition levels: apparent metabolic energy [AME] = 3,500 kcal/kg, crude protein [CP] = 20% vs AME = 3,400 kcal/kg, CP = 19.42%; feed types:dry vs wet; probiotics levels: 0 mg/kg vs 300 mg/kg). Results: During d 5 to d 15, greater average daily gain (ADG) and average daily feed intake (ADFI) (p<0.05) were observed in probiotics treatments. During d 15 to d 25, gain:feed (G:F) ratio (p<0.05) were significantly improved in probiotics, wet feed and high nutrition diet. Moreover, two interactions i) between nutrition levels and feed types, and ii) between nutrition levels and probiotics were found in G:F ratio. Furthermore, there was a significant positive interaction on G:F among those 3 factors (p<0.05). Overall, increasing ADG, ADFI, and G:F ratio were detected in probiotics treatment significantly (p<0.05). Besides, an obvious reduction on fecal score was observed in probiotics treatment from d 0 to d 5 (p<0.05). There was an interactive effect on fecal score between feed types and nutrition concentrations from d 5 to d 25 (p<0.05). Conclusion: These results indicated that probiotics supplementation could benefit growth performance and reduce the frequency of watery feces. Besides, wet feed program (feed:water = 1:1.25) could improve the G:F. The effect of liquid feed or probiotic could be influenced by dietary nutrition density in weaned piglets. An increased value of G:F was obtained when wet feeding a high nutrition diet (100 kcal higher than NRC 2012 recommendations) was supplemented with probiotics for 15 to 25 days.

The purpose of the current study was to investigate the effects of 4-week health promotion intervention program consisting of high-intensity aerobic exercise to improve energy consumption and cardiorespiratory capacity, circuit training to strengthen muscular strength and endurance and education for lifestyle changes on the obesity level, physical fitness, insulin resistance and metabolic syndrome among overweight or obese elementary school students. Twenty three overweight or obese children as obese group and 15 normal body weight children as normal group were recruited. The health promotion program consisted of two exercise sessions and one education session, 3days/week in 4-week. Obesity level(body mass index, waist circumference, %body fat), physical fitness(muscular strength, muscular endurance, flexibility, cardiopulmonary fitness), insulin resistance(homeostasis model assessment of insulin resistance) and metabolic syndrome risk factors(blood pressure, fasting glucose, triglycerides, high density lipoprotein cholesterol) were measured. There was not significant decrease in obesity level; however, there were significant improvement in physical fitness, insulin resistance and metabolic syndrome risk factors after program participation among obese children. As a result, through participation in the summer camp consisting mainly of exercise, the improvement of the physical fitness level and the decrease of insulin resistance had an effect on the reduction of the metabolic syndrome frequency.

In the global pursuit of carbon neutrality, the rapid increase in the adoption of electric vehicles (EVs) has led to a corresponding surge in the demand for batteries. To achieve high efficiency in electric vehicles, considerations of weight reduction and battery safety have become crucial factors. Copper and aluminum, both recognized as lightweight materials, can be effectively joined through laser welding. However, due to the distinct physical characteristics of these two materials, the process of joining them poses technical challenges. This study focuses on conducting simulations to identify the optimal laser parameters for welding copper and aluminum, with the aim of streamlining the welding process. Additionally, a Graphic User Interface (GUI) program has been developed using the Python language to visually present the results. Using machine learning image data, this program is anticipated to predict joint success and serve as a guide for safe and efficient laser welding. It is expected to contribute to the safety and efficiency of the electric vehicle battery assembly process.

PURPOSES : This paper numerically evaluates the contribution of transverse steel to the structural behavior of continuously reinforced concrete pavements to understand the role of transverse steel. METHODS : Two-lane continuously reinforced concrete pavements with and without transverse steel were analyzed through finite element analysis with the aid of commercial finite element analysis program DIANA; the difference in their structural behavior such as deflection, joint opening, and stress distribution was then evaluated. Twenty-node brick elements and three-node beam elements were used to model concrete and steel, respectively. Sub-layers were modeled with horizontal and vertical tensionless spring elements. The interactions between steel and surrounding concrete were considered by connecting their nodes with three orthogonal spring elements. Both wheel loading and environmental loading in addition to self-weight were considered. RESULTS : The use of transverse steel in continuously reinforced concrete pavements does not have significant effects on the structural behavior. The surface deflections change very little with the use of transverse steel. The joint opening decreases when transverse steel is used but the reduction is quite small. The transverse concrete stress, rather, increases when transverse steel is used due to the restraint exerted by the steel but the increase is quite small as well. CONCLUSIONS : The main role of transverse steel in continuously reinforced concrete pavements is supporting longitudinal steel and/or controlling unexpected longitudinal cracks rather than enhancing the structural capacity.

Bacterial strain BAS23 was isolated from rice field soil and identified as Bacillus amyloliquefaciens. Based on dual culture method results, the bacterium BAS23 exhibited potent in vitro inhibitory activity on mycelial growth against a broad range of dirty panicle fungal pathogens of rice (Curvularia lunata, Fusarium semitectum and Helminthosporium oryzae). Cell-free culture of BAS23 displayed a significant effect on germ tube elongation and mycelial growth. The highest dry weight reduction (%) values of C. lunata, H. oryzae and F. semitectum were 92.7%, 75.7%, and 68.9%, respectively. Analysis of electrospray ionization-mass spectrometry (ESI-MS) and $^1H$ nuclear magnetic resonance (NMR) spectroscopy revealed that the lipopeptides were iturin A with a C14 side chain (C14 iturinic acid), and a C15 side chain (C15 iturinic acid), which were produced by BAS23 when it was cultured in nutrient broth (NB) for 72 h at $30^{\circ}C$. BAS23, the efficient antagonistic bacterium, also possessed in vitro multiple traits for plant growth promotion and improved rice seedling growth. The results indicated that BAS23 represents a useful option either for biocontrol or as a plant growth-promoting agent.

Purpose: The purpose of this study was to estimate the effects of lifestyle factors on metabolic syndrome (MS) among Korean adults ($age{\geq}20$). Methods: A total of 7,798 subjects (weighted subjects=37,215,961) were recruited from the 2009 Fourth Korea National Health and Nutrition Examination Survey (KNHANES IV-3). Data were analyzed by t-test, ${\chi}^2$-test, and logistic regression in consideration of strata, cluster and weight as national data using the SAS 9.1 program. Results: The prevalence of MS by definition of AHA/NHLBI and waist circumference cutoff points for Koreans was 22.4%. The mean clinical MS score for MS patients was 3.4, but the mean score for the non-MS group was 1.2 out of 5.0. Among the lifestyle factors, smoking (OR=1.024), stress ($0.546{\leq}OR{\leq}0.587$) and drinking (OR=1.005) had significant influence on the MS risk and MS scores, but exercise did not. Conclusion: The results of this study indicate that further research is necessary on the effect of lifestyle factors on MS risk and nurses should focus on effective programs about smoking, stress and drinking for the prevention and reduction of MS risk.

Plate that have cutout inner bottom and girder and floor etc. in hull construction absence is used much, and this is strength in case must be situated, but establish in region that high stress interacts sometimes fatally in region that there is no big problem usually by purpose of weight reduction, a person and change of freight, piping etc.. Because cutout's existence gnaws in this place, and, elastic buckling strength by load causes large effect in ultimate strength. Therefore, perforated plate elastic buckling strength and ultimate strength is one of important design criteria which must examine when decide structural elements size at early structure design step of ship. Therefore, and, reasonable elastic buckling strength about perforated plate need design ultimate strength. Calculated ultimated strength change several aspect ratioes and cutout's dimension, and thickness in this investigation. Used program applied ANSYS F.E.A code based on finite element method.
