A Propeller-Anemometer is an instrument used specifically, to measure the wind speed. The accurate measurement of the wind speed is vitally important such required by any weather stations. In this research, the measurand of the instrumentation was the rotational speed of the propeller and the instrumentation result or output data was wind velocity. The speed measured was recorded digitally in the computer by using specific software. A specific sensor used to measure a variable by converting information of the variable (rotational speed of the propeller) into a dependent signal such as electrical signal in form of voltage. The development of Propeller-Anemometer involved few sets of instrumentation process and equipment. It included three major parts, mechanical, electronics and computer. The main instrumentation processes were physical and signal interfacing, signal conditioning, logic interfacing, data transmission to computer and processing the data. Generally, this paper presents the overall concept and design of Propeller-Anemometer Instrumentation. However, an emphasis was mainly in designing and building the interfacing system, hardware and software. Basically, for the first phase of the development, this project designed and built the RS232 terminal using Peripheral Interface Controller (PIC), PIC16F873. The hardware can be interfaced to computer or other compatible devices. This routine converted input voltage from the circuit to speed (velocity) and transmitted them afterwards to the target device by using the RS232 transmission protocol. This implementation implied a computer display as visual interface. For the purpose of this paper, RS232 data transmission was carried out using a Microsoft Visual Basic software routine.

Purpose: The purpose of this study was to identify predictors of cardiovascular risk factors of type 2 diabetic patients. Methods: Diabetic patients (N=160) were interviewed from November, 2003 to June, 2004. The 24 hour dietary recall, the International Physical Activity Questionnaire, the Diabetes Management Self-Efficacy Scale for patient with Type 2 diabetes, the Revised Summary of Diabetes Self-Care Activities Measure Scale and Parma Cardiovascular Risk Index were used to measure the predictors. Data were analyzed by descriptive analyses, Pearson correlation coefficients, and stepwise multiple regression using the SPSS WIN 10.0. Results: Mean dietary intakes of the participants were protein(P) of 64.5g, carbohydrate(C) of 280.74g, fat(F) of 30g, and calcium of 511.45mg. The ratio of CPF was 75:17:8. About 45% of the participants didn't exercise on a regular basis. The levels of self-efficacy, self-care, and cardiovascular risk factors of the participants were moderate. Self-efficacy was the most important predictor of cardiovascular risk factors along with self-care, exercising for more than 6 months, carbohydrate intakes and levels of physical activities. Conclusion: The findings of the study suggest that intervention programs increasing self-efficacy on diabetic management would be more beneficial than the fractional approach focusing only on diet or physical activities.

The purpose of this study was to identify the effects of the guided imagery program on stress of adolescents. The study design was nonequivalent control group pretest-posttest study. The Data were collected from the 1st to 30th of September in 2000. Two schools were selected as an experimental group and a control group. Each group included two classes. The experimental group was consisted of 40 male students and 42 female students and the control group was consisted of 41 males and 42 females. The guided imagery was provided with audiotapes to the subjects in the classroom for 8 minutes per each therapy, 5 times a week for 4 weeks. The pretest was given before the therapy to measure variables for both groups and the posttests were performed twice after 2 weeks and 4 weeks from the start of intervention. The Instruments used in this study were perception of stress scale developed by Park(1996), Vividness of Imagery Scale; short form of bett's test scale developed by Sheenhan(1967). The data were analyzed by the SAS program using Chi-square test, t-test, repeated measure ANOVA and Bonferroni correction. The results of this study are as follows: 'The level of stress of adolescents who received the guided imagery will be significantly lower than that of control group' was supported(F=10.14, p=.00). In conclusion, the guided imagery was suggested as an effective nursing intervention did reduce the stress of adolescents which school nurses could utilize for adolescents at school.

Objectives : This study is aimed to evaluate the diagnostic value of Ryodoraku for traditional Korean medicine practice reported in the Korean literature. Methods : A search of seven Korean databases was performed up to May 2011 using the search term 'Ryodoraku(in Korean)'. All clinical studies on diagnostic Ryodoraku characteristics were included. Results : The search yielded 59 studies, of which 5 were considered suitable for this analysis. Four were observational studies. Only one was a controlled trial. Average Ryodoraku score(RS), mean values for each measure point, physiologic limit, number of Pyesaek and Gyeokcha, and pattern classification were used as references for the analysis. Correlations were observed between average RS and idiopathic Parkinson's disease, some sub-groups of respiratory disease, chronic low back pain, and menopause. Some mean values for measure points showed particularly high or low tendencies in patients with idiopathic Parkinson's disease, chronic low back pain, and menopause. Positive correlations were observed between the number of Pyesaek and H-Y stage in idiopathic Parkinson's disease and F2(肝) and the modified Kupperman's index with menopausal women. The four classes, organized based on Ryodoraku pattern, showed differences in various characteristics. Conclusions : Since only five studies met the experimental conditions, this evaluation of the diagnostic value of Ryodoraku in various situations is limited. Future studies should be conducted using various physiologic and pathologic situations.

Empathy was defined in this study as the vicarious affective response of a person to the perceived experience of another. The purpose of this study was to study the relationship between empathic development of children and intimacy with parents, socio-economic status, and children's empathic response to specific affective situations happy, sad, angry and fearful. The subjects for this study were 8-, 10-, and 12-year-old children attending an elementary school located in Seoul. Among the subjects, 158 boys and 149 girls lived with their parents, and 20 boys and 35 girls were reared in orphanges. They were from a residential area with higher, middle, and lower class families. The instruments consisted of two modified empathy measures and two questionnaires developed by the researcher. One of the empathy measures was based on Feshbach & Roe's affective situation test for empathy. In order to determine the eight themes, 20 children were interviewed individually about situations that made them "happy, sad, angry, and afraid". From the pool of responses, eight themes representing happy, sad, angry and fearful situations were selected. Each story consisted of a series of three pictures accompanying narration. Another modified empathy measure was developed by the researcher based upon Bryant's empathy scale. This measure consisted of 17 statements describing happy, sad, angry and fearful situations. The items in this scale were selected from a pilot study. The two questionnaires developed by the researcher were to test children's intimacy for their parents and feminity. The data was analyzed with T-test and F-test. Children's intimacy with their parents, particularly, son's intimacy with their mothers, was a significant variable in empathic development. Children living with their parents had higher scores on Feshbach & Roe's Empathy Test than those brought up in orphanages. In general, the older the children the higher the empathy score. Girls were more empathic than boys on Bryant's scale. The subjects showed their highest empathy score in the sad, and the lowest in the fearful situation. The older the children the higher the empathy score in the sad and angry situations. These results reflected children's life experiences and cultural differences. Particularly, mother-son intimacy found in this study contrasts with the mother-daughter intimacy found in American studies.

Purpose: This study was conducted to analyze occupational and leisure-time physical activity(LTPA) in male office workers and to examine factors related to LTPA. Method: The subjects for this study were 226 male office workers, from eight work places located in Seoul, who had no physical restrictions. Minnesota LPTA Questionnaire (Taylor et al., 1978) revised by Kim(1997) was used to measure LTPA and revised Tecumseh Occupational Physical Activity Questionnaire (Motoye, 1971) was used to measure occupational physical activity. The data were collected from May 4 to May 19, 2001 using a semi-structured questionnaire with interviews and self reports. The collected data were analyzed using SPSS Windows 10.0 Program. Results: The results of this study are summarized as follows. 1. The mean level of physical activity was 8,716.9kcal/wk. The occupational physical activity was at 6,605kcal/wk(75.8%) and the level of LTPA was 2,111.4kcal/wk (24.2%). 2. Using 2,000kcal/wk as a base for categorizing LTPA as active or inactive, it was found that there were 94 subjects(41.6%) in the active group. 3. Subjects in their thirties had a lower level of LTPA than subjects in other age groups (F=3.484, p<.05). Physical activity, self-efficacy (r=.405, p=.000) and perceived health status (r=.301, p=.000) were positively related to LTPA. 4. Participants in club activities had a higher level of LTPA than those who did not (t=-2.369, p=.020). Support for physical activity(r=.164, p=0.13) was positively related to LTPA. Conclusion: This study suggested that to increase physical activity in male office workers, physical activity promotion programs should be established according to age and sex especially for those who are in their thirties and for women, and should include strategies strengthening support through peer groups and family, developing club activities and increasing physical activity self-efficacy.

The imbalance between reactive oxygen species (ROS) production and total antioxidant capacity (TAC) in seminal fluid indicates oxidative stress and is correlated with male infertility. A composite ROS-TAC score may be more strongly correlated with infertility than ROS or TAC alone. We measured ROS, TAC, and ROS-TAC scores in semen from 127 patients and 24 healthy controls. Of the patients, 56 had varicocele, eight had varicocele with prostatitis, 35 had vasectomy reversals, and 28 had Idiopathic infertility. ROS levels were higher among infertile men, especially those with varicocele with prostatitis (mean ${\pm}$ SE, 3.25 ${\pm}$ 0.89) and vasectomy reversals (2.65 ${\pm}$ 1.01). All infertility groups had significantly lower ROS-TAC scores than control. ROS-TAC score identified 80% of patients and was significantly better than ROS at identifying varicocele and idiopathic infertility. The 13 patients whose partners later achieved pregnancies had a mean ROS-TAC score of 47.7 ${\pm}$ 13.2, similar to controls but significantly higher than the 39 patients who remained infertile (35.8 ${\pm}$ 15.0; P < 0.01). ROS-TAC score is a novel measure of oxidative stress and Is superior to ROS or TAC alone in discriminating between fertile and infertile men. Infertile men with male factor or idiopathic diagnoses had significantly lower ROS-TAC scores than controls, and men with male factor diagnoses that eventually were able to initiate a successful pregnancy had significantly higher ROS-TAC scores than those who failed.

The tribological properties and van der Waals attractive forces and the thermal stability of films are very important characteristics of highly hydrophobic fluorocarbon (FC) films for the long-term reliability of nano system. The effect of thermal annealing on films and van der Waals attractive forces and friction coefficient of films have been investigate d in this study. It was coated Al wafer which was treated O2 and Ar that ocatfluorocyclobutane ($C_4_{8}$) and Ar were supplied to the CVD chamber in the ratio of 2:3 for deposition of FC Films. Static contact angle and dynamic contact angle were used to characterize FC films. Thickness of films was measured by variable angle spectroscopy ellipsometer (VASE). Nanotribological data was got by atomic force microscopy (AFM) to measure roughness, lateral force microscopy (LFM) to measure friction force, and force vs. distance (FD) curve to evaluate adhesion force. FC films were cured in N2 and vacuum. The film showed the slight changes in its properties after 3 hr annealing. FTIR ATR studies showed the decrease of C-F peak intensity in the spectra as the annealing time increased. A significant decrease of film thickness has been observed. The friction force of Al surface was at least thirty times higher than ones with FC films. The adhesive force of bare Al was greater than 100 nN. After deposit FC films adhesive force was decreased to 40 nN. The adhesive force of films was decreased down to 10 nN after 24 hr annealing. During 24 hr annealing in $N_2$and vacuum at $100^{\circ}C$ film properties were not changed so much.

High-speed vessels require good resistance and seakeeping performance for safe operations in rough seas. The resistance and seakeeping performance of high-speed vessels varies significantly depending on their hull forms. In this study, three planing hulls that have almost the same displacement and principal dimension are designed and the hydrodynamic characteristics of those hulls are estimated by high-speed model tests. All model ships are deep-V type planing hulls. The bows of no.2 and no.3 model ships are designed to be advantageous for wave-piercing in rough water. No.2 and no.3 model ships have concave and straight forebody cross-sections, respectively. And length-to-beam ratios of no.2 and no.3 models are larger than that of no.1 model. In calm water tests, running attitude and resistance of model ships are measured at various speeds. And motion tests in regular waves are performed to measure the heave and pitch motion responses of the model ships. The required power of no.1 (VPS) model is smallest, but its vertical motion amplitudes in waves are the largest. No.2 (VWC) model shows the smallest motion amplitudes in waves, but needs the greatest power at high speed. The resistance and seakeeping performance of no.3 (VWS) model ship are the middle of three model ships, respectively. And in regular waves, no.1 model ship experiences 'fly over' phenomena around its resonant frequency. Vertical accelerations at specific locations such as F.P., center of gravity of model ships are measured at their resonant frequency. It is necessary to measure accelerations by accelerometers or other devices in model tests for the accurate prediction of vertical accelerations in real ships.

This study is to develop the well-fit brassieres by observing the changes in the breast sizes and shapes, the surface area of the breast through the arm movements of 3 types (0$^{\circ}$ , 90$^{\circ}$ and 180$^{\circ}$) in vortical motion. The 11 elementary girls who are aged 12 participated in this experiment. To obtain the measures regarding the surface area of the breast, replicas are made at each motion. The results of this study are as fellows: 1. The changes in the breast sizes and shapes at each motion By increasing the motions of the arm movement, the following measure items are inclined to decrease: Shoulder length, Upper blast girth, Bust girth, Under bust girth, Upper bust depth, Bust depth, Under bust depth, Nipple to nipple breadth, Horizontal distance of bust, Horizontal length of the cup, Bust height, Cup size. By increasing the motions of the arm movement, the fellowing measure items are inclined to increase: Center point of shoulder~B.p., Shoulder point~B.p., Center point of shoulder~armpit, Upper Bust breadth, Bust breadth, Under bust breadth, Vertical distance of Bust. 2. The changes in the surface area of breast at each motion By making the replica to observe changes in the surface area, which are sectioned to 4 parts(area 1 to area 4), and volume of breast at each motion, the results are as follows: At 0$^{\circ}$and 180$^{\circ}$, the sizes of each part are ordered as the following: area2>area1>area4> area3. At 90$^{\circ}$, the sizes of each part are ordered as the following: area2>area1>area3>area4. Through these orders, it is found that the upper and inside part of the breast huts the inclination to increase so along as the motions of the arm movement increase. Also, the total surface area increases so long as the motions of the arm movement increase. As a reset of the F-test on the changes in the each surface areas, the surface area by arm movements, the significant differences among the each surface areas are found.
