  • This research intends to survey family environment, health behavior and health status of the students in urban-rural elementary schools and analyze those factors comparatively, and use the result as basic material for school health teacher to teach health education in connection with family and regional areas. It also intends to improve a pupil's self-abilitiy in health care. The subjects involve 2,774 students of urban elementary schools and 583 student in rural ones, who were selected by means of a multi -stage probability sampling. Using the questionnaire and school documents, we collected data on family environment, health behavior and health status for 19 days. Feb. 2nd 1998 through Feb. 20th 1998. The R -form of Family Environment Scale (Moos, 1974) was used in the analysis of family environment(Cronbach's Alpha =0.80). Questionnaires of Health Behavior in School-aged children used by the WHO in Europe(Aaro et al., 1986) and the ones developed by the Health Promotion Committee of the Western Pacific(WHO, 1995)(adapted by long Young-suk and Moon Young-hee(1996)) were used in the analysis of health behavior, as well documents on absences due to sickness, school health room-visits, levels of physical strength, height, weight and degree of obesity were used to determine health status. In next step, We used them with an $X^2$-test, t-test, Odds Ratio, and a 95% Confidence Interval. 1. In two dimensions of three, family-relationship (t=3.41, p=0.001) and system -maintenances(t= 2.41, p=0.0l6) the mean score of urban children were significantly higher than those of rural ones. In the personal development dimension however, there was little significant difference. Assorting family environment into 10 sub-fields and analyzing them, we recognized that urban children were superior to rural children in the sub-fields of expressiveness (t =3.47, p=0.001), conflict (t=0.48, p=0.001), active-recreational orientation (t = 1.97, p=0.049) and organization (t=4.33, p=0.000). 2. Referring to the Odds Ratios of urban-rural children's health behaviors, urban children set up more desirable behavior than rural children wear ing safety belts (Odds Ratio =0.32, p=0.000), washing hands after meals(Odds Ratio = 0.43, p= 0.000), washing hands after excreting (Odds Ratio = 0.39, p=O.OOO), washing hands after coming - home ( Odds Ratio = 0.75, p = 0.003), brushing teeth before sleeping(Odds Ratio =0.45, p=0.000), brushing teeth more than once a day (Odds Ratio =0.73, p=0.0l2), drinking boiled water (Odds Ratio = 0.49, p=0.000), collecting garbage at home(Odds Ratio=0.31, p=0.000) and in the school(Odds Ratio =0. 67, p=0.000). All these led to significant differences. As to taking milk(Odds Ratio = 1.50, p=0.000), taking care of eyesight(Odds Ratio=1.41, p=0.001) and getting physical exercise in(Odds Ratio = 1.33, p=0.0l9) and outside the school(Odds Ratio = 1.32, p=0.005), rural children had more desirable behavior which also revealed a significant difference. There was little significant difference in smoking, but the smoking rate of rural children(5.5%) was larger than that of urban children(3.9%). 3. Health status was analyzed in terms of absences, school health room-visits, levels of physical strength, and the degree of obesity, height and weight. Considering Odds Ratios of the health status of urban-rural children, the health status of rural children was significantly better than that of the urban ones in the level of physical strength(t=1.51, p=0.000) and the degree of obesity(t=1.84, p=0.000). The mean height of urban children ($150.4{\pm}7.5cm$) is taller than that of their counterparts($149.5{\pm}7.9$), which revealed a significant difference (t =2.47, p=0.0l4). The mean weight of urban children($42.9{\pm}8.6kg$) is larger than that of their counterparts($41.8{\pm}9.0kg$), which was also a significant difference(t=2.81, p=0.005). Considering the results above, we can recognize that there are significant differences in family environment, health behavior, and health status in urban-rural children. These results also suggestion ideas for health education. What we would suggest for the health program of elementary schools is that school health teachers should play an active role in promoting the need and importance of health education, develop the appropriate programs which correspond to the regional characteristics, and incorporate them into schools to improve children's ability to manage their own health management.

  • The purpose of this research is to suggest basic materials for the practical infection precaution program to protect health care workers from hospital infection by grasping their compliance level of Universal Precautions and examining the factors affecting them. The number of the health care workers we studied were 486, including the doctors, the nurses, and the lab technicians who were working in a university hospital. The period of this research was from Aug. 18th, 1997 to Aug. 30th, 1997. The method of the study was to measure the compliance level of Universal Precautions with the item of "Universal Precautions" established by CDC in 1987, and examine the questionnaire of 52 questions dividing related factors into socio-populational, individual, socio-psychological and organizational management ones. The data was analyzed by t-test. ANOVA, and chi-square test. The results were as follows : 1. An the compliance level of Universal Precautions, hand washing had the highest score(85.4%), and doctors(18.9%), nurses(44.0%), and lab technicians(7.6%), had a low compliance level in the safe handling of an injection syringe, and item not to handle patients and their samples when the subject suffered from dermatitis or injury had the lowest score of 17.1%. 23.3% of them said that they wear protection gown, goggles and mask. 2. Female's Compliance level of Universal Precautions Was higher than male. 3. The health care workers who had high recognition on Universal Precautions got significantly higher compliance level of Universal Precautions than those have low recognition on Universal Precautions(P<0.001). 4. The health care workers experienced a needle stick injury had a significantly higher compliance level of Universal Precautions than those who had not(P<0.000). 5. The health care workers who had infection protection education got a significantly higher compliance level of Universal Precautions than those who didn't(P<0.000). 6. The health care workers who had a firm belief in the effect of Universal Precautions got a higher compliance level of Universal Precautions than those who didn't. 7. The health care workers who had less conflicts between treating patient arid protecting them-selves got a higher compliance level of Universal Precautions than others with many conflicts. 8. The health care workers who had a high score in organizational management factors got a significantly higher compliance level of Universal Precautions than those with a low score(P<0.000). 9. Only 16.9 percent of the all respondents(82 in number) answered that they knew well or a little about the Universal Precautions, which is very low rate of recognition. 10. The variables which affected the score in organizational management factors were age, sex, education period, work experience, the kind of work, recognition on Universal Precautions, the experience of needle stick injury, revealing dangerous circumstance related to infection, and training on precaution again infection. According to the result above, compliance level of Universal Precautions showed high correlation with sex, the recognition on Universal Precautions, the experience of needle stick injury, training on precaution against infection, the belief in the effect of Universal Precautions, the recognition degree of conflicts and organizatinal management factors. These results could be used as the basic materials for the developing infection protection programs. Also, There should have a systematic training course to elevate a effective compliance level of Universal Precautions as well as the manageeent of infection protection programs.

  • SOO-BAL(Hair Style) is a method Which match hair style to face and clothes with using hair covering and protecting the head. Also SOO-BAL includes personal ornaments using to avoid one's hair be disheveled. In a standpoint of beauty and spirit, etiquette SOO-BAL is a very important thing as one being dressed up. Until now, since just a form of hair style have been studied, hair styling process is nothing to be known and studied. Time after time, our unique traditional SOO-BAL is forgotten with clothes and then this th-esis will be classified hair styling form follow-ing a form of hair style in royal palace of the C-hosun dynasty. According to the record of HAE DONG HISTORY, it shows the same of attire between Ko-rean and chinese style in ae of the chosun. The reason in that there were no any certain boundary border and the interaction of culture between two countries was happened spontaneously at ancient time like the GOCHO-SUN age. Until the period of the three states, the korean attire be changed had gone with chinese one s-imilarly. The chinese form gave to influence on the EONJIN MEURI·POON-GI-MYEONG MEURI·JJO-CJIN MEURI·MOOK-EUN GOONG-BAL MEURI·OL-LIN MEURI·SSANGSANG-TU ME-URI be drawn wall painting in the KOKUR-YU. And a gold chignon accesso-ry unearthed in a MOO-RYOUNG royal mausoleum is proof of the korean attrire be changed with chinese. In the shilla dynasty at three years after Cjin-Deuk(A.D. 649) reign. It was recorded that the dynasty let women wear the form of chinese attire. Also in the koryo dyn-asty, a rod-like hairpin (BIN-YEU) and DANG-GI employing EON-JIN MEURI was used. The SOO-BAL based on the Confucianism had lots of regulations which limited to use ornaments with classes of society in the CHOSUN dynasty. Until YOUNG CHO and CHUNG CHO period. EONJIN MEURI be decorated GACHAE was announced by dynasty as ind-ulging in luxury. Women of yangban used a rod-like hairpin and a chignon accessory made by jewerly. And 1-owly women weared a rod-like hairpin made of born and wood to perfom EONJIN MEURI with PUNCHAE. Most unmarried women decorated with DDA-AH-NEULIN MEURI, GUI-MIT MEURI, specially in palace with SAE-ANG MEURI. At palace, one put on a full dress with KEUN MEURI, and a simple dress with ER-YEO MEURI be decorated DDERL-JAM The CHOP-JI MEURI manifested social rank, class. Kids at CHO-SUN age had BA-DUK-PANMEURI and JONG-JONG MEURI. The ornament things are GACHE, DDERL JAM with EON-JIN M-EURI, and all kinds of rod-like hairpin and chignon accessory used in JJOK MEURI. IN DANGGE, JE-BI-BURI DANGGI used by ummarried women. DO-TOO-RAK DANGGI and AP DANGGI on a dress suit, and BE-SSI DANGGI used by 3∼4 years ungrown kids etc. were used. And at palace, kinds of CHUPJI used with JJOK MEURI showed social rank. In CHOSUN age, women want to keep shiny hair washed at TA-NO festival day, a treatment of bald hair used a forked remedy. In CHOSUN age, woman Soo-Bal hair style has DAE-SOO·DDEU-KOO-JI MEURI·CHO-P-GI MEURI·EON-JIN MEURI·SAE-ANG MEURI· and so on.

  • The culture reflects the ideology of a particular period in time and such values change according to the needs and requests of that time which eventually becomes an important factorin forming the exterior. The clothing is part of a way that composes and expresses the inherent substance of society and culture. Also, the clothing itself manifests the artistic values and behavior of mankind as an external structure maintaining its place as a big part in culture. The purpose of this study are to elucidat the concept of naturalism, which is discussed in many facets in the modern era; I studied the concept as well as the history of naturalism in order to manifest the meaning of clothing in the context of culture and I explained the concept in terms of the modern era. On such ground, I explained the naturalism expressed through clothing and characterized the exter-nal form of clothing. Also, in order to know the stream of naturalism in the modern context, I referred to the Vogue magazine of the 90s, using Delong's ABC method. Naturalism, in the context of modern fashion is a way to express the nostalgia of nature's vi-ability and purity of ecology apart from the artificial and structural appearance that resulted form scientific enhancement and hence, the ecological crisis. Naturalism pursues the soft- ness and comfort of the natural silhouette, color and material of the human body and it can be said that naturalism emphasizes the mix-ture of three substances : human, nature and clothing. The naturalism can be characterized by the factors expressed in clothing as follows. First, the naturalism shown in the form it-self draws the beauty of the bodyline without any reduction nor exaggeration. Without any distorttion of the human bodyline it shown the curve as one moves along, using the soft material. Second, the naturalism shown in color most-ly uses the natural tone with added white color and other color low in intensity and value like the receded colors of the earth that could be compared to the beauty of ecru. Third, the naturalism shown in the material is thin, light and soft in texture. In order to bring out the most natural curve of the human body, the natural fiber becomes the main material, sometimes, using crude materials. Due to the lindustrial improvement, softness and elasticity is added to the natural fibers giving them an important role as materials. Fourth, the naturalism shown in textile depicts the real natural objects in life. According to my study, the personality of naturalism in modern clothing was shown to be most strong in material and then in the order of form, texture and textile. The material com-posed of the natural silhouette and natural fibers were used to make soft color. In form, Paul Poiret made appearance expressing the natural beauty of the human body without the corset ; it continued with the inner lining making the clothing hard but in the 90s, lining-less, extremely exposed clothes and knit wear is used to emphasize the natural beauty of the body. In color and textile, the tendency spok-en above is not as strong but in color, instead of high intensity or value, the usage of neutral colors with added white color or ecru color, ear-th tone is increasing. In textile, the usage of flowers as natural material is seen frequently. As a whole, naturalistic trend in the 90s is increasing and the modern fashion is breaking out from the artificial and architectural form and conforming to a form that can realize the natural beauty of the human body. And the natural color and textile that conforms to such ideas are being used to pursue the human oriented trend that has appeared due to the increase in usage of soft natural fiber. Nowadays, the idea of returning to nature, defying the artificiality, desiring the leisure and psychological abundance that can be explained as naturalistic way of thinking is necessitated in this modern era as long as humans coexist with nature, this tendency will continue in clothing.

  • The present study is to analyze the dimensions of affective responses according to the types of appeal in underwear advertisements and to find out the influences of affective res-ponses on the attitudes toward advertisement and brands. The research has been made by normative-descriptive survey method with the sample of 654 consumers residing in Seoul and Incheon. The data gaathered was analyzed by the methods of means, standard deviation, ANOVA, factor analysis and regression. The result are as follows : 1. There are 4 dimensions of affective responses ; Emotional dimension, Negative dimen-sion, Upbeat-activation dimension and Sexual activation dimension. 2. Affective responses to the advertising were different according to the characteristics of the consumers. According to the consumer's sex, there are significant differences in each dimension of their affective responses. To the sex appeal advertisement, man show higher degree of affective responses in Emotional, Upbeat-activation and Sexual-activation dim-ensions, while women show higher degree of affective responses in Negative dimension. 3. In case of female consumers, there are significant differences in affective responses to the both appeal type of advertisements according to consumer's age. As the age is increasing. Emotional dimension and Sexual-activation dimension are increasing, but Negative dimension is decreasing in the Ads with sex appeal. In particular, the 19∼24s age group shows strong responses in the Emotional dimension, Upbeat-activation dimension and Sexual-activation dimension to Ads with sex appeal, while it shows the lowest affective responses in Negative dimension. It represents the 19-24s age group is the most positive one to the under-wear advertisements with sex appeal. Consequently, it is proved that the Ads with sex appeal focusing on this age group can be one of the most effective advertising plans. 4. The involvement gets higher, Upbeat-ac-tivation dimension and Sexual-activation dimension are increasing both in males and female groups. But Negative dimension is in-creasing in the female consumer group of low involvement. 5. The attitudes toward advertisements and brands are comparatively stronger in the advertisements using sex appeal type. Regardless of types of appeal in the advertisements, there is a significant difference in their attitudes tow-ard Ads between male and female consumer groups. When Ads are sexual, attitudes toward Ads and Brands are stronger in the female consumer group. But males consumers show com-paratively strong attitudes toward the advertis-ements and brands in both types of appeal. 6. The age of consumers doesn't make any significant difference in their attitudes toward advertisements and brands in both types of appeal. 7. According to the involvement level of the consumers, there are significant differences in their attitudes toward advertisements. In the groups of low involvement, the female consumers show more favorite attitudes toward the advertisements with sex appeal, while the male group show more favorite attitudes toward the non-sex appeal advertisement. But there is no significant difference in consumer's attitude toward brands according to the types of appeal of the advertisement. 8. The affective responses of the consumers caused by the underwear advertisements have a respectable influence on their attitudes toward the advertisements and brands. This research represents that the advertisers should try to arise consumer's positive affective responses such as pleasant, happy, cheerful and warm-hearted emotions by the advertisements. Based on the above results of the research, it can be said that the consumer's affective responses have a strong effect not only on their attitudes toward adver-tisements but on those toward attitude toward the brands.

  • 치아침식증은 순수한 화학적 반응에 의한 치아 경조직의 소실로 정의된다. 침식의 원인요소로는 여러 가지가 이미 거론된 바, 최근에 들어서는 이 중 산성음식과 음료가 중요한 요소로 관심을 모으고 있다. 특히 최근 들어서는 다양한 산성 음료의 소비가 급증하는 추세이고, 성장기 어린이나 청소년이 이러한 음료를 선호하여 음용의 빈도가 우려할 만한 수준으로 치아침식증을 촉진할 것으로 생각된다. 이 중 유산균 발효유는 비교적 저렴하고 쉽게 접할 수 있으며, 어린이가 주 소비자라는 점, 그리고 유치와 새로 맹출한 영구치가 침식에 더욱 취약하다는 점에서 소아치과학 분야의 관심사가 되기에 충분하다고 사료되었다. 따라서 본 연구는 유산균 발효유에 의한 유치의 법랑질 침식 정도를 평가할 목적으로 시행되었다. 시판중인 4 종의 유산균 발효유를 선정하고 각각의 산도, 완충능 및 일부 무기이온 농도를 측정하였다. 그리고 40개의 유치 법랑질 시편을 4개 군으로 나누어 30분, 60분, 90분, 120분 동안 $20^{\circ}C$, 80ml의 각 시료에 담근 후 각 시간대별 법랑질의 침식정도를 알기 위해 표면미세경도를 측정하여 다음과 같은 결과를 얻었다. 1. 본 실험에 사용된 유산균 발효유의 산도는 평균 pH 3.77로서 치아침식증을 유발하기에 충분한 수준이었다. 2. 유산균 발효유에 대한 노출 후의 법랑질 표면경도는 대조군에 비해 모든 시료에서 낮아졌다(p<0.05). 노출시간에 따른 법랑질 표면경도의 변화는 모든 실험군에서 초기에는 급격히 낮아지다가 시간경과에 따라 그 정도가 덜해지는 양상을 보였다. 3. 법랑질이 시료에 노출된 30분에서 120분까지의 법랑질 표면경도 변화양상은 시료마다 유의한 차이를 보였다(p<0.05).

  • 어린이의 공간유지와 교합유도의 치료를 위하여 가철성 장치는 소아치과 임상에서 일상적으로 사용되고 있다. 상악의 경우와는 달리 하악에서는 가철성 장치를 사용하는데 있어 유지력의 저하에 따른 치료효과의 감소, 환자의 불편감과 거부감으로 인한 미착용 등의 문제가 흔히 발생한다. 이것은 유치열기나 초기 혼합치열기 어린이의 경우, 하악구치부의 undercut양이 충분치 못함에도 불구하고, 여기에 협측 undercut으로부터 유지력을 얻는 각종 clasp를 적용하기 때문으로 사료된다. 또한 전통적인 가철성 장치들의 acrylic base plate가 설측에 위치하고 있어 설측 연조직이나 치조능 undercut과 많은 문제를 일으키는 현상을 볼 수 있다. 어린이들은 하악 장치의 작업모형을 위한 인상채득과정에서 술자의 지시대로 혀를 바르게 거상하지 못하는 예가 많은 것도 그 원인요소로 들 수 있다. 본 연구는 전통적인 하악의 Hawley acrylic plate로부터 clasp와 acrylic baseplate의 위치를 바꾸어 협측 base plate와 설측 clasp을 이용한 buccal acrylic appliance를 유치열기 및 초기 혼합치열기 어린이의 구강에 적용하여 그 장단점을 조사하고 환아들의 수용도와 효율성을 기존의 lingual acrylic appliance와 비교, 검토할 목적으로 시행되었다. 공간유지 및 치아이동을 필요로 하는 5개 증례를 대상으로 각 증례에 buccal acrylic appliance와 기존의 lingual acrylic appliance를 모두 적용하여, 유지력, 환자 수용도, 혀의 기능과의 조화, 치료 효과 등의 측면을 상호 비교해 보았다. 조사 결과, 조사 대상의 모든 증례에서 유지력과 환아의 수용도 측면에서 협측 장치가 설측 장치에 비해 월등히 우수한 것으로 나타났다. 또한 치료 효과의 측면에서도 협측 장치는 설측 장치와 유사한 것으로 나타났다. 본 연구를 통하여 하악에 가철성 장치를 사용할 경우, 전통적인 설측 장치와 관련된 각종 부작용을 해결하는 데에 buccal acrylic appliance가 훌륭한 대안으로서 임상적용을 추천할 만 하다고 사료되었다.

  • 중재적 시술의 시술자를 대상으로 방사선 방호용구의 안과 밖의 실제 방사선량을 측정하여 이를 바탕으로 방사선 방호용구의 방사선 차폐율을 비교 분석하는 것이다. 2005년 5월부터 9월까지 중재적 시술 중에서 시행 빈도가 높은 TACE, PTBD를 시행하는 중재적 시술자 4인에게 방사선 방호용구의 착용 시 피폭선량 감쇄효과를 측정하기 위해 각 신체부위별 방호용구 안과 밖에 TLD를 부착하여 피폭선량을 측정하였다. TLD 부착부위는 Goggle inside, Goggle outside, Thyroid protector inside, Thyroid protector outside, Apron inside(waist level), Apron outside(upper chest level), Hand 4th finger(ring type TLD)와 환경방사선을 측정하기 위해 TLD 10개를 Control room 여러 곳에 위치시켰다. TACE 검사시 0.07 mmPb Goggle의 사용으로 연속투시방식에서는 평균 53.8%의 선량율감쇄를 보였으며 펄스투시방식에서는 77.6%의 감쇄효과를 보였고, 0.5 mmPb Thyroid protector의 사용에서는 연속투시방식에서는 평균 88.9%의 선량율감쇄를 보였으며 펄스투시방식에서는 92.8%로 선량율감쇄에서는 유의한 차이가 없었다. PTBD 검사시 0.07 mmPb Goggle의 사용으로 평균 62.7%의 선량율감쇄를 보였으며, 0.5 mmPb Thyroid protector의 사용에서는 평균 89.1% 선량율이 감쇄 되었고 0.5 mmPb Apron의 사용에서도 평균 87.9%의 감쇄효과가 있었다. PTBD 시술은 TACE 시술에 비해 평균 투시시간은 6.14 min이나 적었으나 피폭선량은 체부에서 약 3배, 손에서는 40배 이상 피폭되었다. 납당량이 두꺼운 방호용구를 착용하거나 최소한 권고되어지는 0.5 mmPb 이상의 것을 착용하여야 하며, 시술시 눈을 보호하는 Goggle의 착용을 생활화해야 한다. 테이블 아래쪽에 납커튼을 장착하면 복부의 피폭선량율은 평균 38.4% 감쇄하므로 납커튼을 장착하여 산란선을 차폐하여야 한다. 펄스투시방식을 이용하면 연속투시에 비해 피폭선량율이 평균 59.0% 감쇄되므로 연속투시보다 펄스투시방식을 선택하여 피폭선량을 감소시켜야 한다.
