Vol. 46, No. 2, (2007) 성에 따른 자가건강관리행태는 남·여학생 모두 평균수면시간은 6시간, TV시청시간은 1시간으로 컴퓨터 사용시간은 남학생 2시간·여학생 1시간으로 남·여학생 모두 스트레스해소방법은 음악듣기, 아침식사여부는 매일 먹는다, 간식횟수는 매일 먹는다, 간식선호도는 비스켓, 빵류, 인스턴트섭취횟수는 주1~2회, 선호음식은 육류, 선호음료는 주스류, 체형인지정도는 약간 살찐 체형, 운동을 하지 않는 이유는 시간이 없어서, 운동을 하는 이유는 신체적 건강을 위해서, 음주횟수는 마시지 않는다, 흡연·음주가 학업에 미치는 영향은 학업에 지장이 있는 것 같다. 신경안정제·수면제·각성제 등의 복용여부는 없다로 나타났다. TV시청시간, 아침식사여부, 선호음료, 체형인지정도, 신경안정제, 수면제, 각성제 등의 복용여부에서는 남학생이 더 나은 자가건강관리행태를 컴퓨터 사용시간, 간식선호도, 인스턴트섭취횟수, 선호음식, 음주횟수, 흡연·음주가 학업에 미치는 영향에서는 여학생이 나은 자가건강관리행태를 나타냈다. BMI에 따른 자가건강관리행태는 저체중·정상체중·과체중 모두에서 평균수면시간은 6시간, TV시청시간은 1시간으로 컴퓨터 사용시간은 1시간, 스트레스해소방법은 음악듣기, 아침식사여부는 매일 먹는다로 간식횟수는 저체중·정상체중은 매일 먹는다·과체중은 주 1~2회로 저체중·정상체중·과체중 모두에서 간식선호도는 비스켓·빵류, 인스턴트섭취횟수는 주 1~2회, 선호음식은 육류, 선호음료는 주스류로 체형인지정도는 저체중은 마른체형으로 정상·과체중은 약간 살찐 체형으로 저체중·정상체중·과체중 모두에서 운동을 하는 이유는 신체적 건강을 위해서, 운동을 하지 않는 이유는 시간이 없어서, 음주횟수는 마시지 않는다, 흡연·음주가 학업에 미치는 영향은 학업에 지장이 있는 것 같다, 신경안정제·수면제·각성제 등의 복용여부는 없다로 나타났다. 정상은 저체중·과체중보다 간식선호도에서 과체중은 정상·저제중보다 아침식사여부, 간식횟수, 선호음식, 체형인지도에서 자가건강관리행태가 좋았다. 신체적 자기효능감은 성별로는 남학생이 여학생보다 높게 나타나 유의한 차이를 나타내었고, 계열별로는 유의한 차이가 없었으며, BMI는 정상체중이 저체중과 과체중보다 높게 나타나 유의한 차이를 나타내었다. 이상의 연구결과 청소년들의 올바른 자가건강관리행태를 높이고, 잘못된 생활습관과 식습관을 바로 잡을 수 있는 체계적이고 지속적인 청소년 자가건강교육 프로그램이 개발되어야 할 것이며, 청소년기에 맞는 보다 일반화된 검사를 할 수 있는 자가건강관리행태와 신체적 자기 효능감의 설문지 개발과 자가건강관리의 능동적 실천 방안을 마련해야 된다고 본다. For the study on the type of self-care status according to gender, BMI and physical self- efficacy of high-school students, this study took a census at 1,810 students of 13 high-schools at area of U and P. This study took a Chi-square to compare the type of self-care status according to gender, BMI of high-school students. The study calculate mean, standard deviation and then perform one-way ANOVA to compare physical self-efficacy of high-school students. Verifications on those was executed by Duncan with the significance level of a=.05. The conclusions of this study are followed below. At both boy and girl students: average sleeping time -6 hours, average watching TV time - 1 hour, the methods of releasing a stress : listening to music, yes or no of eating a breakfast -Taking a breakfast everyday, how often they eat snack foods - everyday, the preferred snack foods - biscuit, bread, the frequency of eating fast-foods - 1~2 per week, the preferred foods - meats, the preferred beverage - juices, the cognition on body type - a little fat body. The reason why they don't excise - having no time to excise, the reason why they do excise - To have a healthy body, the frequency of drinking alcohol - zero, the affection of smoking and drinking alcohol on studying - It seems to be, yes of no of taking medicines such as tranquilizer, sleeping drug, stimulant - No. The time of using a computer - boys (2 hours) / girls (1 hour).Boy students have a better types of self-care status than girl students in watching TV time, yes or no of eating breakfast, the preferred beverage, cognition on the body type, yes of no of taking medicines such as tranquilizer, sleeping drug, stimulant. Girl students have a better types of self-care status than boy students in the time of using a computer, the preference of snack foods, the frequency of eating fast-foods, the preferred foods, the frequency of drinking alcohol, the affection of smokingㆍdrinking alcohol on studying. At all under, normal, over-weight students: the average sleeping time - 6 hours, the average watching TV time - 1 hour, the average time in using a computer - 1 hour, the methods of releasing a stress - listening to music, yes or no of eating a breakfast : -Taking a breakfast everyday, the preferred snack foods - biscuit, bread, the frequency of eating fast-foods - 1~2 per week, the preferred foods - meats, the preferred beverage - juices. The reason why they do exercise : -To have a healthy body, the reason why they don't excise -having no time to excise, the frequency of drinking alcohol - zero, the affection of smoking and drinking alcohol on studying - It seems to be, yes of no of taking medicines such as tranquilizer, sleeping drug, stimulant - No. The frequency of eating snack-foods : low & normal - everyday / over - 1~2 times. The normal weight students have a better types of self-care status than low or over-weight in the preferences of snack-foods. the over weight students have a better types of self-care status than the normal or low-weight in yes or no of eating a breakfast, the frequency of eating snack-foods, the preferred foods, the cognition on body type. On gender, it shows a meaningful difference that the boy students are higher than the girl students in the physical self-efficacy. On BMI, it shows a meaningful difference that normal weight are higher than low & over weight in the physical self-efficacy. These results show us that we have to develop a systematic and continuous health education programs for juveniles-self that enhance upright types of self-care status and fix the wrong living and eating habits. And these results also show us that we have to prepare the types of self-care status which can be generally tested for juveniles and the development of census on the physical self-efficacy and active practice plan on self-care status.

Calcium Channel Inhibitor, Verapamil, Inhibits the Voltage-Dependent K⁺ Channels in Rabbit Coronary Smooth Muscle Cells

Ko, Eun A,Park, Won Sun,Son, Youn Kyoung,Ko, Jae-Hong,Choi, Tae-Hoon,Jung, In Duk,Park, Yeong-Min,Hong, Da Hye,Kim, Nari,Han, Jin Pharmaceutical Society of Japan 2010 Biological & pharmaceutical bulletin Vol.33 No.1

<P>We investigated the effect of the phenylalkylamine Ca<SUP>2+</SUP> channel inhibitor verapamil on voltage-dependent K<SUP>+</SUP> (Kv) channels in rabbit coronary arterial smooth muscle cells using a whole-cell patch clamp technique. Verapamil reduced the Kv current amplitude in a concentration-depenent manner. The apparent <I>K</I><SUB>d</SUB> value for Kv channel inhibition was 0.82 μ<SMALL>M</SMALL>. Although verapamil had no effect on the activation kinetics, it accelerated the decay rate of Kv channel inactivation. The rate constants of association and dissociation by verapamil were 2.20±0.02 μ<SMALL>M</SMALL><SUP>−1</SUP> s<SUP>−1</SUP>, and 1.79±0.26 s<SUP>−1</SUP>, respectively. The steady-state activation and inactivation curves were unaffected by verapamil. The application of train pulses increased the verapamil-induced Kv channel inhibition. Furthermore, verapamil increased the recovery time constant, suggesting that the inhibitory effect of this agent was use-dependent. The inhibitory effect of verapamil was not affected by intracellular and extracellular Ca<SUP>2+</SUP>-free conditions. Another Ca<SUP>2+</SUP> channel inhibitor, nifedipine (10 μ<SMALL>M</SMALL>) did not affect the Kv current, and did not alter the inhibitory effect of verapamil. Based on these results, we concluded that verapamil inhibited Kv current in a state-, time-, and use-dependent manner, independent of Ca<SUP>2+</SUP> channel inhibition.</P>

Wet regeneration of waste artificial sand used in sand casting using chemical solutions

Eun Yeong Ko,Kyeong-Ho Kim,Jae Ho Baek,황인성,이만식 대한환경공학회 2021 Environmental Engineering Research Vol.26 No.6

Natural sand and organic binders have been the main materials used in sand casting. However, inorganic binders are used in novel casting technologies, and research on artificial sand as a substitute of natural sand has been conducted. Herein, the wet regeneration of waste artificial sand was performed using a sodium silicate binder. Acidic, neutral, and basic solutions were used for wet regeneration. The effects of binder removal and reusability of the regenerated sand were investigated by comparing the characteristics and strengths of the artificial and regenerated sand. It was demonstrated that the basic solution effectively removed the binder from the surface of the waste artificial sand. The Si-O-Si bond cleavage in the binder occurred due to the high concentration of hydroxide ions in the basic solution. The strength of the regenerated sand treated with the basic solution and that of the artificial sand were similar. Moreover, the strengths of regenerated sands treated with the acidic or neutral solutions were lower than that of artificial sand due to the presence of residual binder. These results indicated that the basic solution was suitable for removing the sodium silicate binder. The quality of the regenerated sand was similar to that of artificial sand.

Eun Saem Ko,Eo Ram Lee,Yeong In Choi,Seo Yeong Kang 한국응용곤충학회 2018 한국응용곤충학회 학술대회논문집 Vol.2018 No.10

Insecticidal and repellent effects of herb extracts were tested against Aedes albopictus and Ochlerotatus togoi that are common among mosquitoes which inhabit Korea. Herb extracts from Mentha×piperita, Ocimum basilicum, and Nepeta cataria were extracted using distilled water and 70% ethanol respectively. Both kinds of mosquitoes were raised in environment control rearing system with air temperature of 25℃, humidity of 70%, and light condition of 14:10(L:D). Insecticidal effect was verified by feeding extracts to mosquitoes(Park et al., 2016.); repellent effect, by measuring their radial distance from extract by time. N. cataria extract using distilled water as a solvent is predominant in insecticidal effect; O. basilicum, using 70% ethanol. In particular, N. cataria has the most outstanding repellent effect.

Soluble receptor for advanced glycation end products inhibits disease progression in autosomal dominant polycystic kidney disease by down-regulating cell proliferation

Lee, Eun Ji,Park, Eun Young,Mun, HyoWon,Chang, EunSun,Ko, Je Yeong,Kim, Do Yeon,Park, Jong Hoon The Federation of American Societies for Experimen 2015 The FASEB Journal Vol.29 No.8

<P>Autosomal polycystic kidney disease (ADPKD) is a highly prevalent genetic renal disorder in which epithelial-lining fluid-filled cysts appear in kidneys. It is accompanied by hyperactivation of cell proliferation, interstitial inflammation, and fibrosis around the cyst lining cells, finally reaching end-stage renal disease. Previously, we found high expression of ligands stimulating the receptor for advanced glycation end products (RAGE) in ADPKD mice. Furthermore, gene silencing of RAGE was revealed to cause reduction of cystogenesis <I>via</I> down-regulation of cell proliferation <I>in vitro</I>, and intravenous administration of anti-RAGE adenovirus <I>in vivo</I> also displayed alleviation of the disease. Here, we attempted to identify the role of soluble RAGE (sRAGE) in inhibiting the progression of ADPKD using 2 different ADPKD mouse models. sRAGE is an endogenously expressed form of RAGE that has no membrane-anchoring domain, thereby giving it the ability to neutralize the ligands that stimulate RAGE signals. Both overexpression of sRAGE and sRAGE treatment blocked RAGE-mediated cell proliferation <I>in vitro</I>. In addition, sRAGE-injected ADPKD mice showed reduced cysts accompanied by enhanced renal function, inhibition of cell proliferation, inflammation, and fibrosis. These positive therapeutic effects of sRAGE displayed little liver toxicity, suggesting it as a new potential therapeutic target of ADPKD with low side effects.—Lee, E. J., Park, E.
