The purpose of the study was to provide good fitting of ready-to-wear pants for adult women. To pursue this purpose, the anthropometric data of Korean in 1992 (ADaM(R) 1.0) were analyze. The subjects were 1,580 women aged from 18 to 50 years. The body measurements of six age groups were compared. The results of data analysis showed that the height measurements( waist height, trochanter height, glutial height, perinneum height) of the late 40's were about 3cm shorter than those of the early 20's. The waist circumference of old subject group was 14.1cm larger than those of the young subject group. With rapid growing of waist circumference, the difference of hip and waist circumference was getting smaller with aging. The average difference between hip and waist circumferences of young adult group (18 to 24 yrs) was 24.3cm (SD 3.6cm) and the meaurement of old adult group (45 to 50 yrs) was 15.0cm (SD 5.6cm). The size of the women's pants which were manufactured by the top 50 manufacturers in Korea were compared. The difference between hip circumference and waist circumference listed on the size tag ranged from 12cm to 32cm. The body measurements of subjects and the standard size categories for pants were compared. The results showed that larger size categorise needed to be added to give better fits for older adult group.

We report herein synthetic results obtained new types of crown ethers containing coumarin group. Crown ethers containing coumarin group 1~3 are hydroxymethyl-15-crown-5-ether linked with 4-hydroxy coumarin-4-acetic acid by esterification reaction. Crown ethers containing coumarin group 1~3 have different cavity in each crown ether rings. The 12-crown-4 ether with coumarin 1 has the smallest cavity size. The 15-crown-5 ether with coumarine 2 has the medium cavity size. The 18-crown-6 ether with coumarin 3 has the largest cavity size. Therefore each crown ether with coumarin group will recognize different ionic radius meta. Because of different hole size in crown ethers, these crown ethers seem to be had different selectivity in luminescent sensors. The crown ethers with coumarine 1~3 synthesized hydroxymethyl-15-crown-5-ether and 4-hydroxy coumarin-4-acetic acid same ratio at one to one. The synthesized crown ethers were characterized respectively by IR, NMR. GC-Mass.

The purpose of this study was to compare the initial apical file(IAF) first Ole that fits to the apex in each canal before and after early flaring to analyze if the size of file to fit to the apex would increase after flaring. Eighty anterior teeth with complete apical formation and patent foramens were selected. The samples were randomly divided into 4 groups(GG, OS, GT, PT Group) of 20 teeth each. A file was fit to the apex in each canal and that size recorded. Radicular flaring were completed using different types of instruments. After flaring a file was again fit to the apex in the same manner as before and its size recorded. The results of this study were as follows : 1. The mean diameter of IAF before flaring(file diameters in $mm{\times}10^{-2}$) was $19.81{\pm}8.32$ before and $25.94{\pm}9.21$ after(p<0.05). 2. The increase in diameter of IAF was approximately one file size for all groups. 3. Ranking of increasing diameter of IAF were GG>CT>OS>PT group. There was a statistically significant difference between before and after flaring(p<0.05). 4 Ranking of the time for flaring were GG>GT>OS>PT group. There was a statistically significant difference between GG group and other groups(p<0.05). 5. In the case without change of IAF diameter, they showed decrease in force after flaring when IAF was pulled out from root canal(p<0.05). This study suggested that early radicular flaring increases the file size that is snug at the apex, and awareness of that difference gives the clinician a better sense of canal size. Early flaring of the canal provides better apical size information and with this awareness, a better decision can be made concerning the appropriate final diameter needed for complete apical shaping.

Variation in the facial pattern and effect of the rotational jaw growth on the facial proportion were studied in serial cephalometric radiographs of 40 Korean children (25 boys, 15 girls) ranging in age from 6 to 13 years. According to Y-axis (N-S-Gn) growth change during the 7 years of period, the subject who had exhibited 'wave-like' manner of Y-axis growth change within ${\pm}\;2^{\circ}$ was classified to the Parallelwise group and the subject who had exhibited Y-axis increase more than $+2^{\circ}$ was classified to the Clockwise rotation group and the subject who had exhibited Y-axis decrease more than $-2^{\circ}$ was classified to the Counterclockwise rotation group. For the comparison of each group, a total of 22 morphologic variables were employed and the data were analyzed by means of computer morphometrics and statistical methods. On the basis of the finding of this study, the following trends were established. 1. The Parallelwise group was $75\%$, the Clockwise rotation group was $12.5\%$ and the Counter-clockwise rotation group was $12.5\%$. 2. The growth pattern of cranial base was related to the rotation of mandible. 9. Maxillary prognathism was occured in the Counterclockwise rotation group and the rotation of palatal plane was occured in the Clockwise rotation group. 4. Mandibular prognathism was occured in the Parallelwise and the Counterclockwise rotation groups, especially in the Counterclockwise rotation group. 5. The degree of maxillo-mandibular divergency was constant in the Clockwise rotation group but decreased in the Counterclockwise rotation and the Parallelwise groups, especially in the Counterclockwise group. 6. There were no differences in the size of the anterior upper facial height (N-ANS) and the posterior lower facial height ((Go-Me)-PNS) but there were differences in the size of the anterior lower facial height (ANS-Me) and the posterior upper facial height ((S-N)-PNS) between each group. 7. The growth increment and the size of the facial depth was not related to the growth pattern of the face but the growth increment and the size of the facial height was related to the growth pattern of the face. 8. Proportional change due to the facial growth rotation was concentrated in the anterior lower face. 9. The most apparent difference between each group was happened in the size of the posterior cranial base (S-Ba) and the facial length (S-Gn).

본 연구에서는 남, 여 중학생의 체형인식에 딱른 외모관리 행동의 실태를 파악하고 비교 분석하여 청소년의 긍정적인 신체이미지 형성의 바람직한 방향을 제시하고자 하였다 조사 대상자는 광주소재 남 여 공학 중학교 7곳의 2. 3학년에 재학중인 435명의 남, 여중학생이었다. 결과분석은 SPSS Package 12.0(Kr)을 활용하였다. 그 결과를 요약하면 다음과 같았다. 먼저, 남, 여중학생들은 실제체형보다 비만하게 인식하는 것뿐만 아니라 실제체형보다 수척하게 인식하는 경향도 컸다. 자신의 체형을 제대로 인식할 수 있는 교육이 필요하다고 본다. 둘째, 신체인식 요인과 외모관리행동의 상관관계를 살펴보면 남, 여 중학생 모두 비만인식에 대해 운동보다는 다이어트로 외모관리를 하는 경향을 보이는데 이것에 대한 적절한 지도가 필요하다고 생각된다. 셋째, 자신의 실제체형보다 수척하게 인식하는 수척왜곡 인식집단과 정상집단의 외모관리행동을 살펴보면 남중학생은 운동관리만 하고 여중학생은 운동관리만 하지 알았다. 서로 차별화된 교육이 필요하다고 생각된다. 넷째 비만왜곡인식집단은 남 여중학생 모두 다이어트관리를 하는 반면 신체보정관리나 운동관리를 하지 않는 경향을 보였다. 실제적으로 운동관리가 가장 필요하다고 인식해야할 집단이 다이어트에만 의존하는 경향은 시정이 꼭 필요하다고 생각된다. 이상과 같이 우리나라 남 여 중학생의 왜곡된 신체인식과 외모관리행동을 바로 잡기 위해서 정규 교과목인 가정과목을 통해 표준체형에 대한 교육이 이루어져야 할 것이며 자신의 실제체형을 올바르게 인식할 수 있도록 하는 지도가 병행되어야 할 것으로 생각된다.

In this study, we examined the inhibitory effect of L. plantarum Q180 on adipocyte differentiation in 3T3-L1 and reduction of adipocyte size in mice fed high-fat diet. L. plantarum Q180 inhibited the adipocyte differentiation of 3T3-L1 cells ($18.47{\pm}0.32%$) at a concentration of $400{\mu}g/mL$ ($10^8CFU/g$). As a result of western blot analysis, the expression of $C/EBP{\alpha}$ and $PPAR{\gamma}$ in 3T3-L1 adipocyte treated with $400{\mu}g/mL$ of L. plantarum Q180 decreased 35.16% and 40.07%, respectively, compared with the control. To examine the effects, mice were fed three different diets as follows: ND (n=6) was fed ND and orally administered saline solution; HFD (n=6), HFD and orally administered saline solution; and HFD+Q180 (n=6), HFD and orally administered L. plantarum Q180. After six weeks, the rate of increase of body weight was 13.7% lower in the HFD+Q180 group compared to the HFD group. In addition, the epididymal fat weights of the HFD+Q180 group were lower than that of the HFD group. The change of adipocyte size was measured in diet-induced obese mice. Consequently, the number of large-size adipose tissue was less distributed in the ND and HFD+Q180 groups than in the HFD group. L. plantarum Q180 has an effect on the inhibition of 3T3-L1 adipocyte differentiation, fat absorption and reduction of adipocyte size. L. plantarum Q180 could be applied to functional food products that help improve obesity.

In this study, as a material used to replace silica fumes for high strength concrete, nano-silica compound with organic functional group for dispersion and with inorganic silica group that can cause a pozzolan reaction is synthesized, These nano silica compound is divided into IC, which is nano size $SiO_2$ with irregularly combined hydroxyl group and carboxyl group, and RC, which is nano size $SiO_2$ with regularly combined hydroxyl group and carboxyl group. The effects of these nano silica compound on the hydration of cement are reviewed. As a result, all of synthesized nano-silica compounds have excellent dispersion on the cement flow, we think that dispersion property is the effect of air entraining by synthesized nano-silica compounds. The result of the microstructure observation showed that the particle size of the synthesized nano-silica is smaller than silica fume and spread evenly among the cement particles. In initial The phenomenon of strength decreasing occurred due to delayed hydration reaction by the synthesized nano-silica with carboxyl(-COOH) and hydroxyl(-OH) functional group.

Objectives : The purpose of this case-control research was to investigate the effects of acupuncture stimulation on autonomic nervous system for patients with PSV and to find out relationship with anti-stress effects. Methods : The study group consists of 24 patients with self-recognition of stress as the case group, and 20 normal person as the control group by similar age. We measured PSV of case and control groups before acupuncture stimulation, prick acupuncture in Hegu(LI4), Taichong(Liv3), Shenme(H7), Neiguan(P6), Zusanli(S36). After treating for 20 minutes, measurement values of PSV were compared for pre-acupuncture and post-acupuncture Results : 1. Pupil size of the case group were decreased significantly after acupuncture stimulation in the 1st 2nd experiments. Pupil size of the control group was decreased significantly after acupuncture stimulation in the 1st experiment. 2. Pupil size of the case group were decreased significantly between the 1st and 2nd experiments before acupuncture stimulation. Conclusion : The results suggest that acupuncture stimulation is associated with changed activity in the sympathetic and parasympathetic nervous system. Measurement values of PSV is suitable to estimate the activity of automatic nervous system.
