It has been generally known that smoking is one of the worst factor increasing disease and mortality in human health since in 1950's and nowadays. But regardless of various proofs about social or economical problems due to smoking, current smoking rate has not been decreased in our country. Until now, most of tobacco use and its addiction researches have been focused on the adolescent or adult women smokers not on the university students. Therefore, the purpose of this study was to investigate smoking cessation of university smokers and analyze the health belief-perceived sensitivity, severity, benefits and barriers- difference, then to provide basic data for effective smoking cessation strategy for university smokers. The subjects were comprised of 181 university smokers from 15 universities in Seoul. The data were collected by structured questionaires. The questionaires were designed to measure general characteristics, smoking cessation and health belief, based on Ahn(2003)'s result on the Study of Smoking attitude, Behavior and Smoking Cessation of Adult Male and Lee(1987)'s result on Relationships Between the Health Belief Model and Smoking Habits. The data were collected from May 5 to 16. The collected data were analyzed by SPSS program. The actual number, percentiles, means, standard deviation, t-test and ANOVA were done. The result of this study were as follows; 1. The general characteristics of the subjects of this study The range of age was from 18 to 34 and the averaging age was 23. The subjects of this study were 141 males and 40 females. The religions were Christianity 25.4%(46), Buddhism 12.7%(23), Catholic 23.2%(42), no religion 37.0%(67). The residential forms were living with family 59.1%(107), cooking food for oneself 28.7%(52), dormitory 5.0%(9), boarding house 1.7%(3). Smoking starting age were university 43.1 %(78), high school 29.8%(54), middle school 14.9%(27), in the army 6.1 %(11), elementary school 1.1 %(2). 2. The smoking cessation of the subjects 80% of current smokers showed quitting smoking decision and 20% have not tried. The frequency of quitting smoking decision were from 1 to above 8 and mean was 3.06. As for smoking cessation plan, 54.7%(99) current smokers answered yes, 3.9%(7) said no, 35.4%(64) had no idea and 6.1 %(11) didn't answer. As for the reason of never quitting smoking decision, 71.42%(25 among total 35) have no need to quit smoking and the others said difficulty of smoking cessation. As for the main reason of smoking cessation decision, 54.7%(99) answered for the health, 7.2%(13) family advice, 15.5%(28) girl/boy friend's advice, 1.7%(3) to save money. As for the reason to fail smoking cessation, 56.7%(68) were will-lack, 17.5%(21) stress, 15%(18) smoking mood, 10%(12) withdrawl symptom. As for the smoking cessation method, 85.0%(125) were oneself-will, 2.7%(4) way acquired by mass-media, 2%(3) doctor's prescription, 2%(3) religion's help, 0.7%(1) smoking cessation school. As for the difficulty in smoking cessation, 42.2%(62) were drinking meeting, 23.1 %(34) no alternative of stress release, 12.2%(18) withdrawl symptom, 11.6%(17) having nothing to do, 7.5%(11) friend's encouragement. As for the most difficult cigarette to quit, 67.8%(99) were all-day smoking except the first smoking in the morning, 32.2%(47) the first smoking in the morning. 3. Health belief as for general characteristics Gender - The total point in benefits showed higher in male(28.5177) than female(26.6750). There was significant difference(t=.778, p<.05). The total point in health belief showed higher in male (105.8298) than female(l00.5000). So there was significant difference(t=.345, p<.05). Age - There was significant difference in benefits between age(10's-25.83, 20's-28.39, 30's-32.00)(F=3.73, p<.05). Smoking starting age - There was significant difference in total point of sensitivity and health belief(sensitivity F=4.00, p<.Ol, health belief F=2.843, p<.05). As for sensitivity, subjects who started smoking in the army showed the highest(33.36) and ones in high school showed the lowest(26.96). The total point in health belief showed the highest in elementary school(l19.00) and the lowest in high school(100.98). 4. Health belief as for smoking cessation There was significant difference in health belief as for smoking cessation(t=0.189, p=0.OO2). Sensitivity point showed higher in smoking quitting trial smokers(29.2) than non-trial smoker (26.9). Severity point showed higher in trial smokers (30.7) than non-trial smokers(28.9). Benefit point showed higher in trial smokers(28.6) than non-trial smokers(26.2). There was no significant difference in barriers point.

윤수정(Su Jeong Yun),이가현(Ka Hyeon Lee),이정남(Jung-Nam Lee),조영균(Young-Kyun Cho) 한국정보기술학회 2022 Proceedings of KIIT Conference Vol.2022 No.6

본 논문에서는 넓은 대역폭과 높은 이득을 갖는 단일요소 자기-전기 다이폴 안테나를 제안하였다. 제안된 안테나는 두 개의 금속판 연결을 통해 전기 다이폴의 매칭 주파수를 조절하여 대역폭을 개선하고, 금속 벽과 다이폴 안테나 사이의 간격 조절을 통해 자기 다이폴의 전류 분포를 변화시킴으로써 이득을 향상시킬 수 있다. 이러한 단일요소 안테나의 성능 개선은 제안된 안테나가 배열 형태로 구성되었을 때 더욱 높은 성능 지표를 기대할 수 있게 한다. This paper presents a single element magneto-electric dipole antenna that ensures a wide-bandwidth and high-gain. The return loss characteristics of the proposed antenna is improved by adjusting the matching frequency of the electric dipole through the connection of two metal plates. The realized gain of the antenna is enhanced by altering the current distribution of the magnetic dipole, which is changed by adjusting the distance between the metal wall and the dipole antenna. With these features, a higher performance array antenna for Ka-band can be achieved.

Detergency is the action of imparting from an undesirable soiled substance. One of the largest applications of detergents is for cleaning of hair skin. Generally, shampoo is a hair care product used for the removal of oils and dirt substance. In this study, detergency of soiled fabrics using PEG hydrogenated castor oil used to be dry shampoo. At first, detergency of soiled fabrics with ethanol was examined. In the best physical properties of ethanol, detergency of soiled fabrics from PEG - 20, 40, 60 and 80 hydrogenated castor oil was tested with Terg - O - Tometer. The detergency was analyzed and compared through the Gravimetric and contact angle. Gravimetric method was able to measure of detergency easily and simply. Contact angle analysis was used to compare good detergency. As results, it was shown that detergency of PEG - 20 hydrogenated castor oil in 60 % ethanol was 11.5 %. In this point, contact angle difference of soiled water was 2.32 ˚. 0.4 g PEG - 20 hydrogenated castor oil in 60 % ethanol was effective for detergency, but the detergency value was limited

Objectives : This study was performed to investigate the clinical manifestations and labora-tory findings, and to see whether the severity of atopic dermatitis(AD) implies a relationship to the clinical and laboratory findings. Methods : Our study was designed by analyzing outpatients with AD via physical examinat-ion, questionnaires and laboratory investigations such as prick test to house dust mites, bacterial cultures, total IgE, IgA, IgG, IgG_4, IgM, and peripheral eosinophil count. Results : 1) Xerosis, ear fissuring and hyperlinear palms were related to the severity of AD(p<0.05). 2) Sweating, foods and aeroallrgen were related to the severity of AD(p<0.05). 3) The presence of family history of AD differed significantly(p<0.05) between the severe group(57.9%) & the mild group(26.3%). 4) The positivity of the prick test to Dermatophagoides pteronyssinus and D.farinae was found in 90.0% of respiratory group and in 30.0% of AD only(p<0.05%). 5) Serum IgE level was higher in the severe group(938.3±601.8 IU/mL) than the mild group(526.7±352.1IU/mL)(p<0.05). 6) Serum IgE level in AD patients with respiratory disease(1025.8±713.2IU/mL) was higher than AD only(403.3±273.4IU/mL)(p<0.05). 7) Peripheral eosinophil counts were higher in the severe group(509.9±389.4/㎣) than the mild group(340.5±219.4/㎣)(p<0.05). Conclusion : The factors related to severity of AD were xerosis, ear fissuring, hyperlinear palms, sweating, food, aeroallergen, serum IgE and peripheral eosinophil count. The AD pati-ents with respiratory allergic disease had higher IgE levels and higher positive rates of prick test with house dust mite.

Chronic neutrophilic leukemia(CNL) is a very rare myeloproliferative disease, characterized by sustained mature neutrophilic leukocytosis with granulocytic bone marrow infiltration, high NAP(neutrophilic alkaline phosphatase) score and absence of philadelphia chromosome, It is frequently accompanied by hepatosplenomegaly, elevated serum vitamin B_12 and uric acid level. For the diagnosis of CNL, the leukemoid reaction, especially secondary to neoplasia, infection and autoimmune diseases, should be excluded. Since Tuohy's first description in 1920, more than 50 cases fullfilling the above criteria have been reported worldwide, and 4 cases in Korea. Several authors have demonstrated the defect of intracellualr killing in the mature neutrophil and this finding correlates well with the very high incidence of fatal infection, The hemorrhagic diasthesis in CNL is caused by functional abnormality of the platelet. This disease has tendency to transform to blastic crisis and acute leukemia as in other myeloproliferative disease, but characteristically shows frequent coexistence with multiple myeloma. Until now , the therapeutic trials in CNL have been disappointing. Hydroxyrea and busulfan can control hyperleukocytosis. On the basis of functional defect in neutrophil, alpha-2b-interferon has been tried and several reports have demonstrated the clinical and functional effect of interferon on CNL. CNL is very rate hematologic disease and there are few report about general aspect of disorder. We report here a typical CNL case presenting with splenomegaly and leukocytosis with a review of the literature.
