Julpyun(traditional Korean rice cake) was prepared by adding silkworm powder(SP) in the ratio of 0%, 3%, 6%, 9% of rice flour, and tested by proximate composition, sensory evaluation, chromaticity and rheological properties. In proximate composition, as the SP increased, amounts of moisture, crude protein and ash increased proportionally. In sensory evaluation test, 6% SP added Julpyun showed the highest score in color, Julpyun added with 3% SP gave the strongest flavor. From the scores of taste, texture and overall quality, 3% SP added Julpyun was evaluated as the best. In rheometer test, hardness increased as the amount of SP increased. Gumminess and brittleness tended to decrease as the ratio of SP increased and 3% SP added Julpyun showed the high value in them.

This study investigated the mate selection preferences of single female teachers by investigating the desired traits in socioeconomic, physical attractions, psychological traits and family roles of their prospected marital partner, in order to explore the current trends in homogamous marriage. A questionnaire was distributed to 295 unmarried female teachers selected by convenience sampling from the various cities. The teachers pursued homogeneity in age, educational attainment, religion, and occupation while they preferred partners with higher income level. In terms of physical assets, the attraction that the teachers felt towards the partner was the most important physical appearances. The respondents preferred partners who are masculine and an androgynous partner. The teachers held high expectations towards their future spouses in that they desired to share the roles of emotional, financial support, child care and kin keeping. A partner who shared modern sex role attitudes was preferred over someone who held traditional one. The pursuit for overall homogeneity reflects that the teachers seek for equality in their relationships with prospected marital partners by exchanging similar characteristic.

We have derived an analytical expression for the sensitivity of the frequency domain small-loop electromagnetic (EM) surveys over a two-layer earth in order to estimate the depth of investigation with an instrument having the source-receiver separation of about 2 m. We analyzed the sensitivities to the lower layer normalized by those to the upper half-space and estimated the depth of investigation from the sensitivity analyses and the mutual impedance ratio. The computational results showed that the in-phase components of the sensitivity to the lower layer dominates those to the upper layer when the thickness of the upper layer is less than 20 m, while the quadrature components are not sensitive to the lower layer over the entire frequency range. Hence we confirmed that the accurate measurement of the in-phase component is essential to increase the depth of investigation in the multi-frequency small-loop EM survey. When conductive basement of 10 ohm-m underlies the upper layer of 100 ohm-m, an accurate measurement of the in-phase components ensures the depth of the investigation more than 10 m even accounting a noise effect, from which we conclude that the small-loop EM survey is quite effective in imaging the conductive plume down to a considerable depth. On the other hand, in the presence of the resistive basement of 1,000 ohm-m, the depth of investigation may not exceed 5 m considering the instrumental accuracy, which implies that the application of the small-loop EM survey is not recommended over the resistive environment other than detecting the buried conductor.

The purpose of this study was to investigate the knowledge, attitude, infection management intention and educational needs among nurses with no experience of new respiratory infectious diseases (NRID: SARS and MERS). Data were collected from 162 nurses working at the general hospitals in B city using structured questionnaires from October 10 to 31, 2017. The infection management intention of NRID was high in those who were over 30 years old, married, highly educated, and had a total working experience of more than 5 years. Nurses' infection management intention for NRID showed a positive correlation between knowledge of NRID (r=.27, p<.001) and attitude toward NRID (r=.65, p<.001). In other words, the higher the knowledge score for NRID, the more positive the attitude and the higher the infection management intention. In addition, the knowledge score related to incubation period, treatment, isolation, and release criteria was low while the educational needs were high. Therefore, in preparation for the possibility of NRID relapse and other NRID in the future, a systematic program addressing these educational needs for nurses should be periodically implemented to enhance infection management.

The purpose of this research is to examine the self-concept in the cyberspace, self-efficacy, relationship with friends, subjective well-being and academic grade among adolescents who are addicted to Internet and those who are not addicted to Internet. A total of 1,057 adolescents (male=545, female=512), 326 from middle school, 361 from high school, and 370 from special education school, participated in the study. The results are as follows. First, qualitative analysis of the conception of self in the cyberspace indicates that those adolescents addicted to Internet reported that in the cyberspace they have fun, followed by they are the same as in real life, they spend time in cyberspace and they can become an imaginary person. Those adolescents not addicted to Internet reported that in the cyberspace they are the same as in real life, followed by they spend time in cyberspace and they can become an imaginary person. When they play Internet games, majority of adolescents in both groups reported that it is fun, followed by they become engrossed and they become aggressive. Second, those adolescents who are not addicted to Internet had higher scores on self-efficacy than those adolescents who are addicted to Internet, including self-regulatory efficacy for learning, relational efficacy, and resiliency of efficacy. Third, the number of friends and close friends that adolescents who are not addicted to Internet were not significantly different from those adolescents who are addicted to Internet. However, those adolescents who are not addicted to Internet were more likely receive social support from friends and were less likely to be social excluded than those adolescents who are addicted to Internet. Fourth, those adolescents who are not addicted to Internet had significantly higher scores on subjective well-being than those adolescents who are addicted to Internet. Fifth, those adolescents who are not addicted to Internet had significantly higher scores on both subjective and objective academic grade than those adolescents who are addicted to Internet.

The objectives of this study were to determine the chemical composition of persimmon pickles and microorganisms associated with the manufacture of persimmon pickles. Moisture content was 80.04% and sugar content was 13.72%, but crude ash content was 4.26% which meant some of sodium chloride in soaking solution were permeated into fresh persimmon. Soluble tannin and total vitamin C contents were decreased from 635.45 mg% and 34.53 mg% to 81.04 mg% and 23.76 mg%, respectively. Free sugars contained in persimmon pickles were glucose, fructose and sucrose, 17 kinds of free amino acids were detected including glutamic acid (24.97 mg%), aspartic acid (24.02 mg%) and leucine (22.33 mg%). Microorganisms asociated with the manufacture of persimmon pickles were identified as Bacillus subtilis, B. cereus, B. pumilus, B. thuringiensis, Candida glabrata, C. guilliermondi and Hansenula cnomala, especially C. glabrata was the strain which caused the swelling of vacuum packages of persimmon pickles in retail stores.

Yoneyama 등이 2001년 기존의 potentiometry 형의 요소 센서보다 우수한 성능을 갖는ampeometry 정의 요소 센서를 제안한 이후, 전자 전달 메커니즘에 관한 관심이 집중되어 왔으나, urease로부터 전극 기질까지의 전자 전달 매질로서 전도성 고분자보다 쉽고 단순한 공정은 아직까지 제시된 바 없다. 본 논문에서는 전도성 고분자로서 polypyrrole(PPy)과 poly(3-methylthiophene)(P3MT)을 이용하여 다공성 실리콘(PS) 요소 센서를 제작하고 각각의 특성을 전기화학적으로 분석하였다. Urease 고정화 전압, 고정화 시간, 고정화 시의 효소 농도, 수소이온 농도 등이 감도에 미치는 영향은 PPy 와 P3MT 각각의 경우 유사한 경향성을 보였다. 감도 특성의 경우, PPy는 다공질 실리콘 전극과 평면 전극 각각에 대하여 1.55 ${\mu}A/mM{\cdot}cm^2$와 0.91 ${\mu}A/mM{\cdot}cm^2$였고, P3MT의 경우는 각각 8.44 ${\mu}A/mM{\cdot}cm^2$와 4.28 ${\mu}A/mM{\cdot}cm^2$의 감도를 보였다. 즉, PPy가 P3MT 보다 일반적으로 높은 감도를 보였고, 다공질 실리콘 전극을 사용하는 경우, 그렇지 않은 경우보다 약 2배외 감도 향상 효과를 기대할 수 있었다. 재현성이나 안정성의 경우는 P3MT 가 PPy 보다 우수하였다. 사용 빈도에 따른 감도 저하는 다공질 실리콘 전극의 경우 직선적으로 감소하셨으나 평면 전극의 경우는 지수함수적으로 감소하였다 시간에 따른 감도 저하 현상은 만15일 이후의 감도를 기준으로 하여, 10% 미만의 감도저하를 보임으로써 PPy, P3MT 모두 우수한 특성을 보였다.

The purpose of this study is to verify the self-respect moderating effect on adolescents with emotional problems because of neglect and abusive experiences. The results are as follows: First, the level of abusive experiences was higher than that of neglect in adolescents. General characteristics including genders and individual family situations were found to be the influences causing emotional problems in adolescents. Second, adolescents with high levels of neglect and abuse experienced high levels of depression, social anxiety, aggression and physical symptoms. Third, even though self-respect did not have a strong moderating effect on the emotional problems of adolescents who suffered neglect and abuse, there was a difference between the abuse experience and the emotional problem in the inclination test results for the high and low group based on the average of the self-respect of the respondents. The results of this study suggest that the need for a stronger variable to reduce the negative emotional state among adolescents experiencing neglect and abuse is related to emotional problems.

The purpose of this study is to examine the psychometric properties of the Korean Children's Rejection Sensitivity Questionnaire (K-CRSQ). In order to investigate the reliability and validity of the K-CRSQ, the data were collected from 286 elementary students. The results are as follow : Internal consistency and test -retest reliability of the K-CRSQ were .83~.89, .72~.79, respectively. To test the convergent and discriminant validity, participants were separated into two samples and administered the K-CRSQ and ten validity indices. The correlation of K-CRSQ and validity indices scores suggested that the convergent and discriminant validity are high. High rejection sensitivity group revealed high score on intentional attribution, depression, anxiety, and aggression. In contrast, low rejection sensitivity group revealed high score on self-esteem, perceived competence, and social support. The results were compared with previous studies and the implication and limitation were discussed.
