Paper records were generally degraded by some factors from atmospheric environments, like temperature, relative humidity or air pollutants. In this study, the degradation behavior of paper records by single or mixed gases of NO₂, SO₂, HCHO and TVOC was evaluated. The mechanical, optical and chemical properties of 4 kinds of paper (acid and neutral-based printing paper, traditional Hanji, and filter paper) were directly and indirectly affected by gaseous harmful materials. The brightness and L<SUP>*</SUP> value in all papers were slightly increased by accelerated aging under gaseous HCHO and TVOCs, but highly decreased by conditions under gases NO₂ and SO₂. The optical properties of paper records were most vulnerable in acid-based paper and high stable in filter paper and traditional Hanji by air pollutant degradation. The aging treatments under mixed gas pollutants including NO₂ resulted in decrease of physical, mechanical and optical properties of paper, so it was supposed that the concentration of NO₂ gas would be strictly controlled for optimum indoor air quality management in domestic storage centers for paper records.

목적 : 양성 갑상선 결절 환자에서의 PEI의 치료효과 및 부작용을 알아보고자 하였다. 방법 : 양성 갑상선 결절 환자 88명을 대상으로 초음파 소견에 따라 낭종성 결절, 복합성 결절, 고형성 결절 등 세 그룹으로 분류후 전체 및 각각에 대한 PEI의 치료효과 및 부작용을 조사하였다. 결과 : 양성 갑상선 결절 환자 88명을 PEI로 치료후 결절의 크기가 50%이상 감소한 경우는 전체 환자중 77.2%이었고 각 결절별로 살펴보면 고형성 결절에서 52.6%, 복합성 결절에서 72.4%, 낭종성 결절은 92.5%이었다. 부작용은 동통, 결절내 출혈, 감염, 결절의 누출등이 있었으나 대부분 무증상이었다. 결론 : PEI는 양성 갑상선 결절 환자증 적응증을 잘 살펴 고려해 볼 수 있는 치료법이라 생각되며 특히 낭종성 결절 환자에서 주사기에 의한 흡인후에 재발한 경우 일차적인 치료로 PEI를 고려해 볼 수 있겠다. Ultrasonography(US)-guided percutaneous ethanol injection (PEI) has been performed for the treatment of autonomous functioning thyroid nodules, thyroid cysts, & cold thyroid nodules. The author studied the efficacy of PEI in the treatment of benign cold thyroid nodules both solid and cystic (complex & pure). Eighty-eight euthyroid outpatients (age:44.2±13.9years, 75 women and 13 men) with benign cold thyroid nodules or simple thyroid cysts (69 with a single nodule and 19 with a prominent nodule within multinodular goiter) were includied in this study. After PEI, each subtype of thyroid nodules was divided into three groups in according to volume reduction complete response (90% or more of volume reduction), partial response (50% or more of reducton but below 90%), and failure (below 50% or increase in size) group. Overall response rates of PEI for benign thyroid nodules were complete 45(51.1%), partial 23(26.1%), failure 20(22.7%). In 20 cold solid nodules, complete response was observed in 6(30.0%), partial response in 5(25.0%), and failure in 9(45.0%). In 28 complex cysts, complete response was observed in 8(28.6%), partial response in 12 (42.9%), and failure in 8(28.6%). In 40 pure cysts, complete response was observed in 31(77.5%), partial response in 6 (15.0%), and failure in 3 (7.5%). Side effects comprised pain 8 (9.2%), intranodular bleeding 13 (14.6%), extracapsular leakage 1(1.1%), infection 1 (1.1%), increased size l(1.1%), and none 64(72.7%). PEI may prove a safe & effective tool for the therapy of cold thyroid nodules in selected cases and may be the treatment of choice of recurrent thyroid cysts. However, further investigation involving a larger number of patients and a longer follow-up is needed.

A 4-year-old boy had hemihypertrophy and hemihypertrichosis on his left leg since he was 10 months old. Any other family history or past medical history was not noted. The circumference of left calf was 2cm thicker than right calf, and magnetic resonance image also showed hypertrophic muscles. Folliscopic image revealed increased density and thickness of hairs on his left calf. No other systemic abnormalities were detected. The patient was diagnosed idiopathic hemihypertrophy with hemihypertrichosis. Hemihypertrophy is a rare congenital abnormality, showing a fast growth of one side of the body. It usually accompanies diseases such as Beckwith- Wiedemann syndrome, Silver-Russell syndrome, Proteus syndrome. Hypertrichosis shows excessive growth of body hair over the normal range. Three types of congenital hypertrichosis were reported, congenital hypertrichosis lanuginosa, congenital hypertrichosis terminalis and nevoid hypertrichosis. Nevoid hypertrichosis is similar to hypertrichosis in our patient. Co-presence of hemihypertrophy and hemihypertrichosis is very rare and the etiology is unclear. 4 cases of hemihypertrophy with hemihypertrichosis without any abnormalities, so-called idiopathic hemihypertrophy with hemihypertrichosis, were reported. It needs further evaluation to determine whether this condition is a just incidental coexistence or a new syndrome. Herein, we report a case of idiopathic hemihypertrophy with hemihypertrichosis.

In the modern era, buying an imitation product or having luxury brand logos on nails has substituted for the purchase of the luxury items themselves. The purpose of this study is to find a substitute for the pattern of over-consumption in which people buy expensive items to make themselves look better. For this, a literature review was performed regarding the creation of nail art design. The luxury brand ‘LOUIS VUITTON’ was selected, and the monogram from this brand was used as a motif in nail art. After dividing the nail design into two groups (a group of the nail art design preferred by people in their 20-30s, a group of the designs preferred by people aged 40-50s), treatment methods were diagramed, and a scope of research was set. The study results found that using luxury brand logos in nail art temporarily satisfies modern women’s desire for buying a luxury brand item and creates general image coordination.

There have been so many researches about problems of cigarettes and relation of smoking and heath since 1950's and generally known that smoking is one of the worst factor of increasing disease and mortality. No matter what such many proofs about various problems of smoking have been researched, smoking rate of current male collage students has not been decreased. Besides, most of the researches about cigarette use and its addiction have been focused on the adolescent or adult women smokers or adult male, not male collage student. Therefore, the subject of this study is about smoking attitude and smoking behavior of male collage students by general features. Smoking attitude was analyzed by modifying 'Guidelines for the content of tobacco smoking surveys of the general population'(WHO, 1982). Two hundred of male collage students participated to the distributed questionnaire for one week in May. The smoking attitude was categorized into duration of smoking and number of cigarette per day(CPD), and nicotine dependency, investigated by Fagerstrom Tolerance Questionnaire(FTQ) (Fagerstorm & Schneider, 1989). All statistics were performed by procedure of SAS according to number, percentage, mean, standard deviation, and ANOVA. The results are as follows: 1. Smoking attitude level was mean 25.73±5.15 marks, ranging from 13 to 39 marks of the total 40 marks. 2. Duration of cigarettes, number of cigarette per day, and nicotine dependency were mean 5.14±2.84 years, 12.88±6.85 pieces, and 4.78±1.69, respectively. 3. Smoking attitude showed significance according to general features such as marital state and allowance, but the significance according to marital state is not valuable because the numerical difference is so big between married one and single that they cannot be compared with each other. 4. Duration of smoking was significant according to general features such as age and allowance. 5. Smoking amount showed significance the factors of age only. 6. ll1ere was no significance in nicotine dependency according to general features. As a result, smoking attitude of male collage student in this study shows moderate level. Smoking attitude and duration is significant according to allowance, and smoking amount is significant according to age. Nicotine dependency according to general features is not significant but comparing with the preceding study about adult male, male collage students in this study are respectively more nicotine-dependent than adult male smokers. In conclusion, the right allowance usage strategies and effective heath education focused on the young are needed. In addition, helpful programs and information spreading strategies are necessary for establishing higher level of smoking attitude. At last, systemic regulations in daily living for ""anti-nico-dependent"" and perspective reforming of male university student are needed for reducing nicotine dependency.

조영석,나소영,이효진,홍우정,김군순,김도희,구본정,송민호,김영건,노흥규 충남대학교 의과대학 의학연구소 2002 충남의대잡지 Vol.29 No.2

배경 : 폐경후 골다공증은 심각한 문제로 대두되고 있다. 현재 Alendronate는 폐경후 골다공증의 치료제로서 널리 쓰이고 있다. 저자는 Alendronate의 골밀도에 효과를 알아보고 골다공증의 위험인자에 따른 Alendronate의 반응 정도를 평가하기 위하여 본 연구를 수행하였다. 방법 : Alendronate를 평균 12개월간 복용한 35명의 폐경후 골다공증환자에서 체질량지수와 폐경후 기간에 따른 치료효과를 조사하였다. 결과 : 전체 대상군에서 Alendronate 10㎎을 12개월간 투여한후 골밀도의 평균 변화율은 요추와 대퇴골 경부에서 각각 7.83±7.39%와 2.99±9.22%이었다. 과체중군에서 평균변화율은 요추와 대퇴골 경부에서 각각 7.15±4.5%와 3.05±2.86%였다. 양군간에 통계적 유의성이 있는 차이는 없었다. 폐경후 7년이 경과되지 않은 군에서의 평균변화율은 요추와 대퇴골 경부에서 각각 6.9±5.3%와 5.71±0.08%였다. 양군간에 통계적인 유의성이 있는 차이는 없었다. 결론 : 마른체형이 골다공증의 발병에는 영향이 있으나, Alendronate 치료효과의 차이는 없는 것을 확인할 수 있었다. 더불어 폐경이 있고 7년이 초과된 군과 년이 경과되지 않은 군에서의 Alendronate 치료효과의 차이는 없는 것을 확인할수 있었다. 이는 골흡수가 상당히 진행된 상태에서도 Alendronate가 치료효과를 가지고 있음을 반영한다고 할 수 있겠다. Postmenopausal osteoporosis is a serious health problem. The aminophosphonate Alendronate is widely used for treatment of postmenopausal osteoporosis. We studied the effect of l0㎎ of alendronate given daily for mean 12 months on bone mineral density in 35 women(mean age 61yrs. mean BMI 23.24㎏/m^(2)) with osteoporosis. An over weight group is defined such that BMI was above 23㎏/m^(2). All the women received 1500㎎ calcium carbonate daily. The bone mineral density of L-spine and femoral neck was measured by dual-energy X-ray absorptiometry. Alendronate increased BMD at mean 12 months at the L-spine (7.15±4.5%) and femoral neck(3.05±2.86%) in normal women. Alendronate increased bone mineral density at 12 months at the L-spine(6.00±5.3%) and femoral neck(4.17±4.87%) in overweight women. There was no difference between two groups. In the less than 7 years group of postmenopausal duration. alendronate increased bone mineral density at 12 months at the L-spine(6.9±4.9%) and femoral neck(3.18±7.1%). In the more than 7 years group of postmenopausal duration, alendronate increased hone mineral density at 1% months at the L-spine(6.5±5.3%) and femoral neck(5.71±0.08%). There was no difference between two groups. In postmenopausal women with osteoporosis, therapy with alendronate produced significant increases in BMD of the L-spine and femoral neck in both group. There was no difference between normal and over-weight groups. and between less than 7 years group and more than 7 years group of postmenopausal duration.

HSS STI-CMP적용을 위한이중 패드의 최적화

As the device geometry shrinks to the deep submicron region, chemical mechanical polishing(CMP) planarization become a more essential technique of advanced ULSI process. Also, CMP process was required for the global planarization of inter-metal dielectric(IMD), inter-level dielectric(ILD) layers and interconnections with free-defect. Especially, the complete global planarization of IMD, ILD and interconnections can be achieved only with the CMP process. However, as the IMD and ILD layer gets thinner, several problems were found in the CMP process. It does have various problems such as dishing effect, torn oxide defects and nitride residues in oxide. So, it leads to severe circuit failure, which affects yield. In this paper, we studied the characteristics of polishing pad, which can apply STI-CMP process for global planarization of multilevel interconnection structure. Also, we investigated the effects of different sets of polishing pad, such as soft and hard pad. As an experimental result, hard pad showed center-fast type, and soft pad showed edge-fast type. Totally, the defect level has shown little difference, however, the counts of scratch was defected less than 2 on JR111 pad. Through the above result, we can select optimum polishing pad, so we can expect the improvement of throughput and device yield.
