This study confirms and describes the meaning of the true experience on sexual perception of female college students as it is. Thus this study, revealing the structure of the meaning, tried to use phenomenal study tool as qualitative research design in order to seek nursing intervention for them. The method of data collection of this study was achieved February, 2000$\sim$August, 2000 through systematic interview, participation and observation from a focus group. The number of each focus group was 3 to 4, and the study analyzed with Giorgi method after selecting total 3 groups with 10 to saturate data, considering of the closeness among group members. The results are as follow; 1) Feeling psychological uneasy : feeling special mood, mysterious thing, tense thing, curious thing, concealing thing 2) Being to someone : receiving unilaterally, giving ahead, attracting attention, being to, being selected unilaterally 3) Feeling like to do together : relying, contacting, being together 4) Accepting another one's self : understanding the partner, taking responsibility for each other, enduring, trusting each other 5) Trying to be best to the partner : physically being pure, mentally being pure, being only one person to the partner, being open to each other, feeling free 6) Harmonizing conditions with conditions : considering appearance, one's family, economic support and so on 7) Making a love without premise of marriage : making a difference between marriage and love 8) Being a difference between men and women : being a different position, being shameful (because of not having a boyfriend), indecent thing 9) Being for a new life : conceiving a new life 10) Being able to have body touch : being able to kiss, being able to sleep together, being able to touch body 11) Being able to make homosexual love : being able to do homosexual love From the above results, right sexual education should deliver the value of sex which exists for life. So we need to develop the Korean-typed sexual education, according to the social and cultural background and reasonable demand level of education subjects. Furthermore we should give systematically connected education through the development of sexual education program by a developmental stage on the sex with broad and dynamic features, revealing different shapes each period of life. Since the members' value by culture is very different, reasonable and healthy sexual education cannot be done through a education program from foreign cultures. Consequently, the development of the study and program on sexual perception of Korean female college students suitable for the Korean cultural situation will be done.

The purpose of this study was to obtain basic data of nutrition education for obese children and to examine food habits, food behaviors, and nutrition knowledge. A convenience sample of 84(male:62, female:22) obese children was selected from "98 Children Nutrition Camp". The survey design employed a structured questionnaire. The results of this study were summarized as follows. 1. The percentage of the subjects who overestimated their body weight was higher in female compared to male. Only 35.9% of highly-obese subjects considered them as 'very fat'. The experience of weight control was higher in female than in male, and it was also higher moderately- or highly-obese subjects compared to mildly obese. 2. 64.3% of subjects reported that they regularly eat breakfast. The percentage of the subjects who indicated that they eat at regular meal time or they eat very irregularly was highest in the highly-obese subjects. 3. 34.5% of subjects reported that they eat very fast. The eating speed was slower in female compared to male, and in obese subjects. 55.4% of subjects reported that didn't eating out. 4. 80.9% of subjects had snacks, and most of them had snack between lunch and dinner. The reason the subjects eat snack was hunger. The most favorite snack was cookies. 5. The most preferred and distasteful food was meats(32.1%) and vegetables(67.1%), respectively. 6. The score of food behaviors was relatively low in most subjects. 7. The level of nutrition knowledge was in order of fair(83.1%), poor(9.6%), excellent(7.3%), and was higher in male compared to female. Consequently the results of this study showed to disagreement among food habits, food behaviors and nutrition knowledge, and feel keenly the necessity of education connecting of these. This education had to be practical education to change food behaviors.

In this paper, a unified inverse transformer is designed for HEVC and VP9. The proposed architecture performs all modes of HEVC and VP9 in the unified inverser transformer, such as $4{\times}4{\sim}32{\times}32$ HEVC IDCT, $4{\times}4$ HEVC IDST, $4{\times}4{\sim}32{\times}32$ VP9 IDCT, $4{\times}4{\sim}16{\times}16$ VP9 IADST and $4{\times}4$ IWHT. Same computations are used in HEVC IDCT and VP9 IDCT, except for the scales of the coefficients. Similarly, same computations are used in HEVC $4{\times}4$ IDST and VP9 $4{\times}4$ IADST, except for the scales of the coefficients. Furthermore, HEVC IDCT, VP9 IDCT, and VP9 IADST are the subsets of upper level IDCTs. The proposed architecture reuses multipliers when the computation is identical. Also it shares adders and butterfly structures even when the multiplier coefficients are different. So it reduces the hardware size significantly. Synthesized in 0.18 um technology, the gate count is 456,442 gates. which achieved 22.6% reduction compared to conventional architectures.

A CMOS rail-to-rail high voltage buffer amplifier is proposed to drive the gamma correction reference voltage of large TFT LCD panels. It is operating by a single supply and only shows current consumption of 0.5mA at 18V power supply voltage. The circuit is designed to drive the gamma correction voltage of 8-bit or 10-bit high resolution TFT LCD panels. The buffer has high slew rate, 0.5mA static current and 1k$\Omega$ resistive and capacitive load driving capability. Also, it offers wide supply range, offset voltages below 50mV at 5mA constant output current, and below 2.5mV input referred offset voltage. To achieve wide-swing input and output dynamic range, current mirrored n-channel differential amplifier, p-channel differential amplifier, a class-AB push-pull output stage and a input level detector using hysteresis comparator are applied. The proposed circuit is realized in a high voltage 0.18um 18V CMOS process technology for display driver IC. The circuit operates at supply voltages from 8V to 18V.

Purpose: For aesthetic reasons, composite resin brackets are widely used. However, related studies are rare. This pilot study sought to compare the stress distributions in two commercially available composite resin brackets with metal slot. Materials and Methods: Two commercially available resin brackets -- full-metal slot resin bracket (fSRB) and partial-metal slot resin bracket (pSRB) with straight wire appliance dimension of $0.022{\times}0.028$ in -- were selected. In each bracket, 3-dimensional finite element models were constructed, and stress level was evaluated using finite element analysis. By loading the tipping force and torsion moment, which are similar to those applied by the stainless steel rectangular wire ($0.019{\times}0.025$ -in), stress distributions were calculated, and von Mises stress values were obtained. Results: In pSRB and fSRB, the stress value of the torque moment was much higher than that of the tipping force. The pSRB showed higher stress value than fSRB in both tipping force and torque moment because of the difference in size and configuration of the metal frame inserted into the slot. More stress was also found to be concentrated on the slot area than the wing area in fSRB. Conclusion: The slot form of fSRB was found to be more resistant to the stress of tipping and torque than the slot form of pSRB. In addition, the slot areas -- rather than the wing areas -- of the bracket showed breakage susceptibility. Therefore, resistance to the torque moment on the slot area should be considered in bracket design.

Objectives: This study investigated dietary and lifestyle factors associated with the weight status among Korean adolescents in multicultural families. Methods: This cross-sectional study analyzed 1,751 multicultural families' adolescents who participated in the 2017-2018 Korea Youth Risk Behavior Surveys. Information on dietary and lifestyle factors was self-reported using a web-based questionnaire and this information included breakfast and foods consumption, perceived health status, alcohol drinking, smoking, physical activity, and weight control efforts. Body mass index (BMI) was calculated based on the self-reported height and body weight (kg/㎡). Weight status was assessed according to the 2017 Korean National Growth Chart: underweight (weight-for-age <5^th percentiles), overweight (85^th≤ BMI-for-age <95^th percentiles), and obese (BMI-for-age ≥95^th percentiles). Multiple logistic regression analysis was performed to examine the dietary and lifestyle factors associated with weight status after adjustment for covariates. Results: Among Korean adolescents from multicultural families, the prevalence of overweight/obesity was 20.9%, whereas about 7% of adolescents were underweight. The weight status did not show differences according to gender, school level, area of residence, and household income. Compared to adolescents who did not have breakfast during the previous week, those who had breakfast 3-4 days/week and ≥5 days/week had a 42% (p=0.021) and a 37% (p=0.009) lower prevalence of overweight/obesity, respectively. The adolescents who frequently consumed carbonated soft drinks (≥5 times/week) showed an odds ratio (OR) of 1.69 (95% CI=1.01-2.83) for overweight/obesity relative to those adolescents who did not consume carbonated soft drinks. The OR of being underweight for adolescents who ate fast food ≥3 times/week was 1.97 (95% CI=1.04-3.71) compared to those adolescents who had not eaten fast food during the previous week. Conclusions: Dietary and lifestyle factors were associated with overweight/obesity as well as underweight among Korean adolescents in multicultural families. Our findings could be used to design and provide nutrition interventions for this specific population.
