BACKGROUND/OBJECTIVES: In nutritional epidemiology, collecting self-reported respondent height and weight is a simpler procedure of data collection than taking measurements. The aim of this study was to compare self-reported and measured height and weight and to evaluate the possibility of using self-reported estimates in the assessment of nutritional status of elderly Poles aged 65 + years. SUBJECTS/METHODS: The research was carried out in elderly Poles aged 65 + years. Respondents were chosen using a quota sampling. The total sample numbered 394 participants and the sub-sample involved 102 participants. Self-reported weight (non-corrected self-reported weight; non-cSrW) and height estimates (non-corrected self-reported height; non-cSrH) were collected. The measurements of weight (measured weight; mW) and height (measured height; mH) were taken. Using multiple regression equations, the corrected self-reported weight (cSrW) and height (cSrH) estimates were calculated. RESULTS: Non-cSrH was higher than mH in men on average by 2.4 cm and in women on average by 2.3 cm. In comparison to mW, non-cSrW was higher in men on average by 0.7 kg, while in women no significant difference was found (mean difference of 0.4 kg). In comparison to mBMI, non-cSrBMI was lower on average by $0.6kg/m^2$ in men and $0.7kg/m^2$ in women. No differences were observed in overweight and obesity incidence when determined by mBMI (68% and 19%, respectively), non-cSrBMI (62% and 14%, respectively), cSrBMI (70% and 22%, respectively) and pcSrBMI (67% and 18%, respectively). CONCLUSIONS: Since the results showed that the estimated self-reported heights, weights and BMI were accurate, the assessment of overweight and obesity incidence was accurate as well. The use of self-reported height and weight in the nutritional status assessment of elderly Poles on a population level is therefore recommended. On an individual level, the use of regression equations is recommended to correct self-reported height, particularly in women.

In this study, repowering scenarios are analyzed and evaluated from the economical point of view on a case by case basis. Based on the result of evaluation, the IRR indicates 2.34% on single 750 MW LNG combined cycle unit, 3.56% on 500 MW sub-bituminous PC units and 2.31% on 200 MW circulating fluidized bed combustion units, resulting in not reaching 7% rate of discount rate and being concluded uneconomical. However, proposes that it is most economical and feasible to repower power plant into 750 MW LNG combined cycle unit as long as the economic feasibility can be improved and it is necessary for old anthracite power plant to be repowered than rebuilt under the circumstances of lacking power supply.

Hyperemesis gravidarum is one of the most common symptom in the early pregnancy and if it cause severe malnutrition by means of heavy vomiting as a basic sign of disease of pregnant syndrome, appropriate treatments are necessary. In the clinics the methods of treatment of hyperemesis gravidarum include herb-medication usually. But herb-medication therapy is rather difficult because during pregnancy it may cause vomiting by the smell and taste of herbs. So the author investigated the literatures referred to the external treatments of hyperemesis gravidarum excluding herb-medication and the results obtained here were as follows. 1. The external methods of treatment of hyperemesis gravidarum are various and include moxibustion, the method of applying drug at the umbilicus, ear-acupuncture method, pressure massage therapy, naso-spray method, acupoint injection, intervenous injection 2. Among the external methods of treatment of hyperemesis gravidarum , the method of applying drug at the umbilicus is most variable and almost all prescriptions use Zingiber officinalis Rose, characteristically. 3. Ear-pressure massage method to treat the hyperemesis gravidarum uses the car-acupoints of Gan, We, Shin-mun, Gyo-gam. 4. Among the external methods of treatment of hyperemesis gravidarum , moxibustion, pressure massage, and acupoint injection select frequently Nae-gwan(PC6), Chok-samni(ST36) and Chung-wan(CV12). 5. In the both the internal and external methods of treatment of hyperemesis gravidarum one have to differentiate syndromes in the viewpoint of oriental medicine and treat with the principls of treatment and prescriptions which are fit to each differentiation model under the principle of regulating the stomach and relieving vomiting.

As advances in computer technology, dissemination of smartphones and tablet PCs has increased and digital media has become easily accessible. The performance of computer hardware is improved and the form of hardware is changed, but basically the change in mechanism was not occurred. Typically, the data used in the program is resident in memory during the operation because of the operating system efficiency. So, these data in memory is accessible through the memory dumps or real-time memory analysis. The user's personal information or confidential data may be leaked by exploiting data; thus, the countermeasures should be provided. In this paper, we proposed the method that minimizes user's data leakage through finding the physical memory address of the process using virtual memory address, and initializing memory data of the process.

In this study, a computerized nutritional and health guide program for workers was developed. The dietitian at the work site could utilize periodically conducted medical examination data to develop an effective health care counseling model based on the developed Nutritional and Health Guide Program. A personal computer (Pentium II PC MMX-150, 32MB RAM, 2.95 GB HDD) with Microsoft Visual Basic 6.0 Enterprise Edition and Microsoft Access 97 installed, was used. The Nutritional and Health Guide Program consisted of seven main menus and 43 sub-menus. Included in the main menu were Basic Information, Periodic Health Check-ups, Visitors' Consultations, Nutritional/Health Tips, Nutritional Education according to Diseases, Help and Exit. In the Periodic Health Check-up menu, dieticians could input the health examination data of employees and touch for the recommended treatments for diseases such as obesity, diabetes, high cholesterol, hypertension and hepatitis. The Visitors'Consultation menu has been designed to compile health information about the employees who sought consultations. The Nutritional/Health Tips menu was designed to provide 14 kinds of programmed nutritional educational media and information. In the Nutritional Education According to Diseases menu, the dietitian could judge the subject's willingness to obtain treatment based on the Stage of Change Model. According, the content of the administered respective nutritional education was classified by stages. The Help menu, provide a chart of the method and procedure used as nutritional guidelines, by which the results of the health examination were classified as people in good health and those requiring special medical attention. The results of the evaluation of this program showed highly positive rates for usefulness (4.09), convenience (4.04), lettering size (4.02), interest (3.93), design (3.49). It also showed that 97.5% of the subjects thought that this program would be helpful for implementation of their company's nutritional educational program. Therefore, this menu could help dietitians plan, conduct, and evaluate their nutritional guidelines for employees. It is expected that The Nutritional and Health Guide Program developed in this study will play a role as a scientific and effective guide in conjunction with health examination results.

As architectures have recently become high-risers and megastructured, stable high strength products have been ensured. Accordingly, use of precast concrete accouplement has been increased in order to facilitate air compression and rationalize construction. Since not only external heating but also internal temperature rise caused by the accumulation of cement hydration heat in manufacturing process, precast concrete members with large cross-section used for high-rise mega-structure's columns and beams may exhibit different temperature history compared to the precast concrete members for wall and sub-floor with relatively small cross-sections. Therefore, this study aims to elucidate the characteristics of temperature history of mass concrete members cast with high-strength concrete for precast concrete application. In this study, large cross-sectional precast concrete mock-up, unit cement quantity, and temperature histories in manufacturing precast concrete member under different curing condition were inclusively investigated.

This study was undertaken in order to examine the relationship of control, perceived health status, self efficacy, social support, and demographic characteristics to health promoting lifestyle of nursing students, and to determine factors affecting health promoting lifestyle of nursing students. The subjects were 270 students of a single university in Busan. The instruments used for this study was a survey of general characteristics, health promoting lifestyle (47 items), control(8 items), perceived health status(6 items), self-efficacy(17 items), and social support(18 items). Data analysis was done by use of mean, percentage, t-test, ANOVA, Pearson Correlation coefficients and stepwise regression with a SPSS PC+ program. The results of this study are as follows : 1) The average item score for the health promoting lifestyle was less than 2.43. In the sub-categories, the highest degree of performance was interpersonal relationships (2.94) and the lowest degree was health responsibility(1.93). 2) Students who were older and higher scores in health responsibility and interpersonal support subscale. Students who had higher grade had higher scores in health support subscale. Students who had experienced disease had higher scores in health responsibility subscale. Students who had experienced exercise had higher scores in health responsibility, exercise and nutrition subscale. 3) Significant correlation between control and self-efficacy, self-efficacy and social support was found. 4) Significant correlations was found between most of the subscales and total health promoting lifestyle. 5) Social support revealed significant correlations with total health promoting lifestyle and all subscales of health promoting lifestyle. Control revealed significant correlations with total health promoting lifestyle and self actualization and health responsibility. Perceived health status revealed significant correlations only with the exercise and nutrition subscale. Self-efficacy revealed significant correlation with the total health promoting lifestyle and all subscales of health promoting lifestyle except exercise and nutrition, stress management subscale. 6) Social support was the highest factor predicting health promoting lifestyles of nursing students(31%).

Purpose: This study was done to provide support material to traditional nursing interventions through investigation of the effect of Auricular acupressure therapy for female staff in the hospital who have dysmenorrhea but cannot be absent from work even with severe symptoms affecting their work and therefore cannot get proper pain management. Method: The participants in this study were 62 women were working in the G-university hospital in Jin-ju, assigned to experimental (30) and 32 control groups (32). The study method was a quasi-experimental, nonequivalent control group non-synchronized design. The experimental group received acupressure treatment (a pin was attached to tape) on the special stimulation points in the inside of the ear, 5 times for 5 seconds, morning, afternoon, and night. Tape without the pressure pin was applied to the same points for women in the control group to evaluate placebo effect. Data were collected from May to November 2007 and were analyzed using SPSS PC+ 12 version. Descriptive statistics, t-test, $x^2-test$, Fisher's exact test, paired t-test, were used to analyze the data. Results: The experimental group showed a significant decrease in dysmenorrhea compared to the control group (t=-2.743, p<.01). In the sub-part, the experimental group showed menstruation related pain (t=-3.726, p<.01), menstruation related to behavioral change (t=-2.421, p<.05) and symptoms however, there was no significant difference related to attention deficit, water retention, and negative image. Conclusion: Application of auricular acupressure therapy was approved for this study and although auricular acupressure therapy was not effective for all of the symptoms, it was effective for dysmenorrhea.

Purpose : This study was performed to compare the characteristics of digital infrared thermographic imaging(DITI) in polycystic ovary syndrome(PCOS) patients with regulary cycling controls. Methods : We studied 19 patients visiting ${\bigcirc}{\bigcirc}$ korean hospital from 7th May 2010 to 8th January 2011. The subjects were categorized in two groups. 8 PCOS patients and 11 healthy regularly cycling controls. We investigated the difference of DITI between two groups by Mann-Whitney U-test using SPSS for window (version 17.0). Results : The average temperatures of five points(In-dang(EX-HN3), GV4, GV6, GV12, GV17) between PCOS and non-PCOS groups showed a little difference though p-value is not less than 0.05. The DITI differences of PCOS group between In-dang and thorax or between In-dang and abdomen showed lower than those of non-PCOS group though not a statistical significant level. Conculsion : The results suggest that DITI differences between PCOS and non-PC OS groups need to be developed to some degree for the diagnosis tool of PCOS.
