This study was conducted to analyze community residents' behavior of Oriental medicine utilization and its related factors in order to provide basic data for formulation of policies on Oriental medicine. The subjects of this study was 500 residents who lived in big or medium sized cities and towns or villages Data were collected from March, 2002 to June, 2002. The results of this study can be summarized as follows. 1) According to socio-demographic characteristics of the respondents, female was 50.3%; 'over 50 years old' 29.9%, 'over college graduate' 39.7%, 'housewife' 23.0%, 'having spouse' 62.1%, 'Buddhist' 50.8%, 'living in big cities' 59.0%, 'middle economic class' 88.1%. 2) The highest proportion of frequency of Oriental medicine utilization was over 10 times(32.5%). The respondents visited Oriental medicine institutions for taking invigorant(51.1%), treatment of diseases in muscle or bone system(30.8%), treatment of diseases in digestive system(6.3%), etc. 3) According to the reasons of utilizing Oriental medicine, the proportion of good effect was highest(36.3%). 66.8% of the respondents replied that Oriental medical fee was expensive, while 0.8% of them replied that it was not expensive. 33.3% of them thought it was proper. 4) 35.5% of the respondents replied that treatment by Oriental medicine could cause side effect and 40.3% of them replied that the side effect could be caused by taking herb medicine. 5) 62.8% of the respondents replied that they would continuously receive opinions on Oriental medicine. The score of knowledge level of treatment by Oriental medicine $6.25{\pm}2.82$ points on the basis of 14 points. 6) The variables significantly influencing utilization of Oriental medicine includes taking diseases, living in big cities, male, upper (economic class, having religion, and effect of Oriental medicine. 7) The factors affecting effect of herb medicine were effect of treatment by Oriental medicine, marital status, knowledge level of Oriental medicine, having diseases, and frequency of receiving the treatment.

한국 어린이의 골 성숙도와 치아 석회화 단계 간의 상관관계
김성진,송제선,김익환,김성오,최형준,Kim, Seong Jin,Song, Je Seon,Kim, Ik-Hwan,Kim, Seong-Oh,Choi, Hyung-Jun 대한소아치과학회 2021 大韓小兒齒科學會誌 Vol.48 No.3
이 연구의 목적은 한국 아동의 골 성숙 단계와 여러 치아들의 석회화 단계 간의 상관관계를 알아보고자 하는 것이다. 만 6 - 14세의 남아 359명, 여아 384명의 수완부 방사선사진, 측방두부규격 방사선사진, 파노라마 방사선사진을 분석하여 평가하였다. 하악 좌측의 7개 영구치의 치아 석회화 단계는 Demirjian이 제시한 방법에 의해 평가되었다. 골 성숙도 단계를 평가하기 위하여 수완부 방사선 사진은 Fishman이 제시한 skeletal maturity indicators(SMI)에 따라 평가되었고, 측방두부규격 방사선사진은 Baccetti가 제시한 cervical vertebral maturation(CVM) 방법에 따라 평가되었다. Spearman의 순위상관분석을 시행한 결과 치아 석회화 단계와 골 성숙도 간에 유의미하게 높은 상관관계가 나타났다(r = 0.40-0.84, p < 0.001). 7개의 영구치 중에서 하악 제2대구치가 골 성숙도와 가장 높은 상관관계를 보인 반면 중절치가 가장 낮은 상관관계를 나타내었다. 남녀 모두에서 하악 견치의 stage G와 하악 제2대구치의 stage F가 SMI 6단계와 CS 3단계에서 나타날 확률이 가장 높았다. 이 연구의 결과에 따르면 치아 성숙도와 골 성숙도 사이에 높은 상관관계가 있으므로, 파노라마 방사선사진에서의 치아 성숙도 평가는 성장기 아동의 골 성숙도를 평가하는 보조적 수단으로 활용될 수 있다. The aim of this study was to investigate the relationships between the stages of calcification of various teeth and skeletal maturity stages among Korean subjects. The samples were derived from hand-wrist, panoramic radiographs, and lateral cephalograms of 743 subjects (359 males and 384 females) with ages ranging from 6 to 14 years. Calcification of seven permanent mandibular teeth on the left side were rated according to the system of Demirjian. To evaluate the stage of skeletal maturation, hand-wrist radiographs were analyzed by skeletal maturity indicators (SMI) system of Fishman and lateral cephalograms by cervical vertebral maturation (CVM) method of Baccetti. Statistically significant relationships were found between dental calcification and skeletal maturity stages according to Spearman rank-order correlation coefficients (r = 0.40-0.84, p < 0.001). The second molar showed the highest correlation and central incisor showed the lowest correlation for female and male subjects. For both sexes, canine stage G and second molar stage F were related to SMI 6 and CS 3. Because of the high correlation coefficients, this study suggests that tooth calcification stages from panoramic radiographs might be clinically useful as a maturity indicator of the pubertal growth period in Korean patients.

Planetary milling에 의한 $TiN_x$의 제조
김성진,김동식,라노,박성범,권원일,김문협,우흥식,안중호,Kim, Sung-Jin,Kim, Dong-Sik,Rahno, Khamidova,Park, Sung-Bum,Gwon, Won-Il,Kim, Moon-Hyup,Woo, Heung-Sik,Ahn, Joong-Ho 한국결정성장학회 2005 한국결정성장학회지 Vol.15 No.3
[ $TiN_x$ ] powder have been fabrication by making of reaction between titanium powder and $Si_3N_4$ bowl during a planetary milling. Milling times were maintained for 1 hour, 5 hours, and 10 hours, respectively. The XRD result showed existence of non-stoichiometric compound of $TiN_{0.26}$ after 5 hours milling and coexistence of TiN with $TiN_{0.26}$ after 10 hours milling. Particle size distribution was investigated by particle size analyzer and microstructure was analyzed by FE-SEM. The size of titanium was decreased with increasing the milling time and the mean size of $TiN_x$ after 10 hours milling was increased by 200 nm. Planetary milling법을 사용하여 Ti 분말과 $Si_3N_4$ bowl과의 반응을 유도하여 $TiN_x$을 제조하였으며, 이때 milling 시간은 1시간, 5시간, 10시간으로 조정하였다. 시편의 물성평가는 X선 회절분석을 통해 결정상의 변화를 분석한 결과 milling 시간이 5시간이 되면 비화학당량적 화합물인 $TiN_{0.26}$가 먼저 생성되고 10시간의 milling에서는 $TiN_{0.26}$과 TiN이 혼재되어 있는 것으로 확인되었다. 입도분석 및 FE-SEM으로 미세구조 분석을 한 결과, milling 시간이 증가함에 따라 Ti 입자사이즈가 감소하는 것으로 나타났으며, 10시간의 milling에서는 평균사이즈가 200nm의 $TiN_x$를 제조할 수 있었다.

After reported that Styrene dimer and Styrene trimer was Endocrine Disrupter, if it was a fact or not, the sales of PSP noodle cup was rapidly decreased and social responsibilities of the substitution materials development was raised. Therefore we had studied many materials like paper, pulp mold, PP injection molding, PP lamination, etc as substitution materials and selected paper cup which was safe in many sides and easy to recycle. Mainly we had checked the shape, safety, stability and recycling possibility of paper cup and secured many data which could prove them.
