Many out patients of the rehabilitation center complaint a pain caused by suffering of MPS, and it brings many different kind of social and ecinomical problems such as medical expenses and the reduction in work efficiency. Therefore, we conducted a research to present a fast and effective treatment to the MPS patients. this research was conducted from November, 1996 to January 1998 with eighteen outpatients who agreed to be the subjects to our reserach. We applied the electric acupuncture on 28 different trigger point on the patients with mostly muscular-skeletal pain and some tender and radiating pain. After the treatment, VRS, VAS, PRI were used to measure the degree of the pain on the patients third and seventh visits, and following results were found. 1. To apply EAP treatment, we acupunctured 6em-Iong needles on Tps region, then the electrodes of pulse generater pg-306 E.S.T were connected on the top of the needles. the electric acupuncture therapy was conducted for 20 minutes with the intensity of 4hz - 60hz(auto wave). The treated electric intensity was the level at which the patients did not feel discomfort. 2. Thirteen out of the 18 participated patients were in their 30s and 40s(72.2%), showing highest frequency. There were more female than male with the ratio of 1 to 1:2. 3. six out of the participated patients (33.3%) had the pain for less then a week, and the average duration of the pain of the participated patients wear 0.8 years. 4. The pain occured mostly in the upper trapezius by 6 part (21.4%), then in the gluteus medius region by 4 part (14.3%). Many of the patients with the pain in the upper back area accompanied varios kind of the referred pains such as radiculopathy, HIVD and Frozen shoulder. 5. MPS occured more frequently on the right side than left side then left side and it seemed to be due to the frequent use of the right hand. 6. There was almost no difference in the measurement of the intensity of the pain right before and after the EAP treatment. Howerver, there was significant decrease in the numerical values of the VAS, and a little bit of decrease in the numerical values of the PRI after the EAP treatment. 7. Based on the results of this present research, it can be concluded that EAP can be used for the treating the myofascial pain syndrome with promptness and safety in most cases.

Objective : The purpose of this study was to investigate the back shape and self-conscious symptoms of the students in S High school using the phase-shifting scanning grating projection Moire interferometer and Questionnaire investigations. Methods : In this study the subjects consisted of 317 pupils[168 boys(53%), 149girls(47%)] attending S high school in Sungnamsi, Kyoungkido in 2002. Their ages ranged from sixteen to eighteen. With the phase-shifting scanning grating projection moire interferometer, the posterior views of the body were taken to see if there are correlation of remainder value of the height spot of left & right shoulder blade and gluteal region in Moire topography. And using questionnaire investigation, we investigated the self-conscious symptoms. Results : 1. In questionnaire investigation, we observed that the ratios of self-conscious symptoms of girls are more than that of boys. The ratios of headache, neck pain, lower back pain, digestive symptom were more than 70% in boys and girls. 2. In Moire topography, more frequent findings of scapular region were observed that left scapular area were higher than right(in boys 69.3%, 60%, 100%, aged 16,17,18, in girls 66.8%, 40.5%, 58.8% aged 16,17,18). 3. More frequent findings of gluteal region were observed that left scapular area were higher than right(in boys 75.2%, 60%, 36.4% aged 16,17,18, in girls 61.1%, 46.8%, 64.7% aged 16,17,18) 4. More frequent findings of reminder value of the vertical lines of cervical and buttock region in Moire topography were observed that the vertical lines of cervical region were inclined to left than the vertical lines of buttock(in boys 73.3%, 92.2%, 100% aged 16,17,18, in girls 72.2%, 77.2%, 73.5% aged 16,17,18) Conclusion : From these results, we found that the self-conscious symptoms were more than in girls than boys; the ratio of headache, neck pain, Lower back pain, digestive symptom was more than the others; the back shape of high school students were not balanced in scapular and buttock region; necks were inclined to left than buttock.

There have been many studies about marginal discrepancy of single restorations made by various systems and materials. But many of statistical inferences are not definite because of sample size, measurement number, measuring instruments. etc. The purpose of this study was to compare the marginal adaptations of the anterior single restorations made by different systems and to consider more desirable statistical methods in analysing the marginal fit. The in vitro marginal discrepancies of three different all-ceramic crown systems (Celay In-Ceram. Conventional In-Ceram. IPS Empress 2 layering technique) and one control group (PFM) were evaluated and compared. The crowns were made from one extracted maxillary central incisor prepared with a 1mm shoulder margin and $6^{\circ}$ taper walls by milling machine. 10 crowns per each system were fabricated. Measurements or a crown were recorded at 50 points that were randomly selected for marginal gap evaluation. Non-parametric statistical analysis was performed for the results. Within the limits of this study, the following conclusions were drawn: 1 Mean gap dimensions and standard deviations at the marginal opening for the maxillary incisor crowns were $98.2{\pm}40.6{\mu}m$ for PFM, $83.5{\pm}18.7{\mu}m$ for Celay In-Ceram, $104.9{\pm}44.1{\mu}m$ for conventional In-Ceram, and $45.5{\pm}11.5{\mu}m$ for IPS Empress 2 layering technique. The IPS Empress 2 system showed the smallest marginal gap (P<0.05). The marginal openings of the other three groups were not significantly different (P<0.05). 2 The marginal discrepancies found in this study were all within clinically acceptable standards ($100\sim150{\mu}m$). 3. When the variable is so controlled that the system may be the only one, mean value is interpreted to be the marginal discrepancy of a restoration which is made by each system and standard deviation is to be technique-sensitivity of each one. 4. From the standard deviations. the copy-milling technique (Celay/In-Ceram) was not considered to be technique-sensitive in comparison with other methods. 5. Parametric analysis is more reliable than non-parametric one in interpretation of the mean and standard deviation. The sample size of each group has to be more than 30 to use parametric statistics. The level of clinically acceptable marginal fit has not been established. Further studies are needed.

This study approaches the effects of Balance Training on excercise performance and the prevention from the injuries caused by excercise. The subjects of the Balance Training program are female exercise beginners and the research period covers 8 weeks from January 10 to March 7, 2003. The research objects are 19 female golf beginners in 30s to 40s, who live in Seoul or Seongnam in Gyeonggi province and have played golf less than 6 months. The programs of the Balance Training and exercise performance were conducted to an 11 experimental group among the 19 research objects at the same time, and only the exercise performance program was applied to an 8 control group for 8 weeks. Before and after 8 weeks' application of the research programs to each group, the research subjects were examined, especially the components of their bodies, the balance and the performance capability were measured both before and after the test. The frequency of injuries by exercise was measured after the test, and the difference of the frequency was compared with the frequency before exercise. First, the experimental group, in a measurement of balance, showed that SN, MB, SAr and SAg of static balance decreased in a situation of MEO, MEC, GEO, GEC, TBEO, TBO, FHEO, FEO(p <0.05), but the control group increased. Second, the analysis on the change of exercise performance indicated better improvement in distance, ball speed, and accuracy of the experimental group than the control group(p<0.05). Third, the experience of injuries showed that there were 2 injuries in the experimental group and 11 injuries in the control group. The injured parts were 2 cases in the hands and fingers of the experimental group, and 1 case in the shoulder, 4 in the elbows, 4 in the hands and fingers and 2 in the lumber of the control group. From the above-mentioned results, it is recognized that the Balance Training program improved the exercise performance of female golf beginners and had good effects on the prevention from injuries. Accordingly, if this program is applied to sports-beginners, it will contribute to the improvement of the public health.

Adolescence is a transitional stage of physical development which occurs during the period from puberty to adulthood. Going through this period, various parts of an adolescent's body grow at different rates, leading to different body shapes and proportions when compared to adults. Therefore, this study aimed to investigate the body sizes and shapes of junior high school boys from ages 13-15 based on body measurement items that are used as the basis for school uniform designs including jackets, shirts, and pants. For this, the study sought the basic data needed to develop body shapes and school uniform patterns for junior high school boys using the data from the 6th Size Korea Survey (2010). Specifically, it provided basic data for the development of school uniform patterns that fit well through the classification of bodies into particular types. After extracting body shape componen a cluster analysis using ANOVA was performed. According to the factor analysis conducted to determine body shape components, 5 factors were obtained as follows: Factor 1: bulk and horizontal size, Factor 2: body height and length, Factor 3: shoulder shape and length, Factor 4: characteristics of horizontal size, Factor 5: shape of the upper body with a variance of 82.62%. To classify junior high school boys' body shape was determined using various characteristics, and a cluster analysis was performed with the variables obtained by the factor analysis. For this, body shapes were classified into 3 different types: Type 1 accounted for 33.4%, with a total of 463 subjects. This type was a tall, long body individual with the smallest bulk and size. Type 2 accounted for 22.7%, with a total of 315 subjects. This type was large in bulk and horizontal size, but the lowest in height and length. Type 3 accounted for 43.9%, with a total of 610 subjects. This type was close to average in terms of horizontal size, length, and height. To develop well-fitting school uniforms for junior high school students, there should be further studies on changes in body shape and their associated causes. The study results will be available as basic data for comparing branded school uniform patterns for junior high school boys and developing school uniform patterns based on body shape, using 3D virtual clothing simulations.

PET/CT검사에 있어서 CT는 해부학적인 정보를 제공할 뿐 아니라 PET영상에 대한 감약 정보를 제공하는 역할을 하고 있다. CT의 감약차를 이용하는 것으로서 검사 부위에 존재하는 여러 가지 변수에 의해 그 정도가 달라질 수 있다. 이것은 현재 본 원에서 PET/CT검사 시에 팔을 몸 옆에 두고 검사하는 것에도 적용할 수 있으며, 이에 본 논문에서는 일부 타 병원에서 시행하고 있는 팔을 머리 위로 올리고 검사하는 방법과 함께 CT값의 변화에 따른 표준섭취계수의 변화를 비교 연구했다. NEMA 1994 PET 모형의 삽입체와 모형의 부피를 고려하여 4:1의 비율로 $^{18}F$-FDG를 주입하였다. 먼저 테플론 삽입체 두 개를 NEMA 1994 PET 모형의 양 옆에 고정시켜 팔을 내리고 있는 상태를 가정하여 영상을 얻었으며 테플론 삽입체를 제거하여 팔을 머리 위로 올린 상태를 가정하여 영상을 얻었다. 앞의 과정을 거쳐 얻은 영상을 재구성 하여 Volume Viewer를 이용해 한 영상면 당 5개의 관심 체적을 설정했고 각 측정값을 평균하여 얻어낸 CT값과 표준섭취계수로 그 변화를 측정하였다. 측정된 값과 폐 관련 암환자의 간에 관심 영역을 설정하고 측정한 값을 비교하여 실제 임상 영상에서의 차이를 측정하였다. 모형 실험결과 테플론 삽입체를 부착하였을 때보다 테플론 삽입체를 부착하지 않았을 때 CT값이 -5.8 HU에서 0 HU으로 평균 5.8 HU 증가하였고 표준섭취계수는 24.64에서 24.29로 평균 0.35 감소하였다. 축방향 균일도는 0.064에서 0.052로 평균 0.012 감소하였다. 환자 실험결과 팔을 내리고 검사하였을 때보다 팔을 머리 위로 올리고 검사하였을 때 CT값은 54.1 HU에서 59.9 HU로 평균 5.8 HU 증가하였고 표준섭취계수는 2.02에서 1.85로 평균 0.17 감소하였다. 테플론 삽입물을 부착한 상태로 검사할 때 보다 테플론 삽입물을 부착하지 않은 상태로 검사할 때 CT값은 증가하고 표준섭취계수는 감소하는 양상을 보였다. 이러한 현상이 일어나는 이유는 감약의 정도와 표준섭취계수의 상관관계에서 찾을 수 있다. CT값이 증가할수록 감약 계수는 비례하여 증가하는데 이것은 결국 CT값이 증가될수록 감약이 증가된다고 볼 수 있다. 따라서 팔에 의해 감약이 과다하게 측정될 수 있으므로 결국 표준섭취계수의 증가로 이어진다고 판단된다. 하지만 그 값의 차이가 매우 적어 진단적으로 유의한 범위라고 볼 수 없다. 팔을 머리 위로 올리고 검사하는 자세가 어깨 및 팔에의 $^{18}F$-FDG섭취와 환자의 고통을 야기하게 된다는 점들을 종합하여 고려해 보았을 때, PET/CT검사 시에는 팔을 내리고 검사하는 것이 합리적이나, 환자의 상태 및 영상의 질적 측면을 고려하여 결정하여야 하겠다.

배경: 기관의 크기와 기관주위의 정상형태에 대한 지식은 임상에서 기도나 호흡관리, 그리고 기관재건술을 시행하는데 중요한 정보가 된다. 흉부 단순촬영은 기관의 직경을 재는 간단한 방법이지만 그 상이 확대되는 경향과 측면촬영에서 어깨와 상이 겹쳐서 나타나는 단점이 있다. 이에 저자들은 한국인 정상 성인의 기관의 정상치를 알기 위해 흥부 전산화 단층촬영을 이용하여 기관의 내경과 단면적을 측정하였다. 대상 및 방법: 남자 43명과 여자34명을 대상으로 하여 각각 나이에 따라 20~39세는 제 1군, 40~59세는 제2군, 60세 이상은 제 3군으로 구분하였다. 흉부 유입구와(Level 1) 대동맥궁에서(Level 2) 흉부 전산화 단층촬영을 이용하여 각각 전후경과 횡경을 재고 그 단면적을 구하였다. 결과: level 1에서 한국인 성인 남자의 기관의 전후경은 15.95$\pm$2.99 m, 횡경은 17.72$\pm$2.13 m이었고, 여자의 경우 전후경은 15.56$\pm$2.12 m, 횡경은 14.18$\pm$2.07mm로 남녀간에 유의한 차이가 있었다(p 0.05). Level 2에서 남자의 전후경은 19.77$\pm$2.57 m, 횡경은 18.02$\pm$2.19 mm이었고 여자의 전후경은 15.35$\pm$1.82 m, 횡경은 15.00$\pm$1.60 mm로 남녀간에 유의한 차이가 있었다 (p 0.05). 기관단면적은 남자가 각 Level에서 279.14$\pm$61.37 $\textrm{mm}^2$(Level 1), 281.93$\pm$63.97 $\textrm{mm}^2$(level 2)였고, 여자가 173.29$\pm$35.81 $\textrm{mm}^2$(Level 1), 181.88$\pm$34.74 $\textrm{mm}^2$(Level 2)로 두 위치에서 단면적은 남녀간에 유의한 차이가 있었다(p 0.05). 기관의 각각의 위치에서 내경과 단면적은 연령군에 따라 고연령층에서 증가하는 추세를 나타내었으나 통계적인 의미는 없었다. 결론: 한국 정상 성인의 기관내경과 단면적의 크기는 성별에 따라 통계적으로 유의한 차이가 있었으나 연령에 따른 차이는 없었고, 전산화 단층촬영은 기관의 내경과 단면적의 크기를 얻는데 비교적 정확하고 안전한 방법이라 생각된다.

목적: 오구돌기하 충돌증후군은 전방 견관절 통증의 원인 중 하나로 알려져 있지만, 현재까지 표준이 되는 영상학적 진단 기준이 없다. 본 연구는 오구돌기하 충돌증후군이 있는 환자군에서 상완-오구돌기간의 거리(CHD)가 좁을 것이라는 가정하에, 오구돌기하 충돌증후군 유무에 따른 상완-오구돌기간 거리를 분석하였다. 대상 및 방법: 견봉하 충돌증후군 환자 124명을 분석하였다. 이학적 검사 및 초음파를 이용한 오구돌기하 주사 검사를 통하여 확진 된 오구돌기하 충돌증후군의 환자군(n=28)을 견봉하 충돌증후군만 있는 군(n=96)과 비교하였다. 견관절의 강직이나, 회전근개 파열이 있는 환자는 대상에서 제외되었다. 상완-오구돌기간의 절대적 거리는 초음파의 내회전과 중립위 자세 및 자기공명 횡단면 영상에서 측정하였다. 또한 내회전과 중립위의 상완-오구돌기간 거리의 차이와, 중립위의 상완-오구돌기간 절대적 거리와의 비율로 정의된 거리 차이의 상대적 비율(relative ratio of distance difference;RRDD)도 함께 측정하였다. 결과: 중립위의 거리는 초음파 영상과 자기공명영상에서 비슷한 값을 보였고(p>0.05), 두 측정값의 두 군간에 유의한 차이는 없었다(p>0.05). 초음파영상을 통해 측정한 두 군간의 중립위 거리 차이는 유의수준에 가까웠다(p=0.07). 상완의 위치에 따른 상완-오구돌기간 거리의 차이는 두 군간에 통계학적 유의성이 없었다. 하지만, RRDD 값은 오구돌기하 충돌증후군 환자군에서 유의하게 더 컸다(p<0.05). 결론: 오구돌기하 충돌 증후군 환자군과 대조군 사이의 상완-오구돌기간 거리 차이의 유의한 차이가 없었다. RRDD값은 오구돌기하 충돌 증후군 환자군에서 더 높았으며, 따라서 오구돌기하 충돌증후군이 있는 환자를 평가할 때 개인의 내회 전시 상완-오구돌기간 상대적 거리도 함께 고려해야 한다.

According as the automation of clerical work(OA ; Office Automation) develops, the use of VDT(Visual or Video Display Terminal) is increasing suddenly. But, in proportion to the spread of office automation(OA tendency), the self-conciousness syptom attendant upon the work is appearing also (Kim, Jung Tae, Lee, Young Ook, 1990). The apparatuses of office enable the clerical workers to be convenient and perform mass businesses. But, they are increasing the opportunity to be exposed to VDT syndrom, techno stress, computer terminal disease, pain by muscle strain(RSI), bradycausia of noise nature, and electromagnetic waves, etc. which are referred to as the new type of occupational diseases to the workers. It is the real situation that the workers to use VDT is complaining of the physical inconvenience sense in the recent newspaper and literature, it is the point of time that the sydrome to come from VDT use and computer terminal disease, etc. must be classified into the occupational disease(Lee, Kwang Young 1990, Lee, Kyoo Hak 1990, Lee, Won Ho 1991, Lee, Si Young 1991, Lee, Joon 1991, Choi, Young Tae 1991, Heo, Seung Ho 1989). In addition, it is the real situation that the scientifitic study result about the scope that electromagnetic waves has influence on the human body has not been suggested yet, and criticism on the stable exposure permission standard about electromagnetic waves to be emitted from VDT and on the problem in the health about electromagnetic waves is continuing. (IEEE Spectrum, 1990). In addition according to the experience of nursery business of industry field, it is the real situation that the patients who consult complaining of physical and mental inconvenience sence, among the users of apparatus of office automation, are reaching 10% of the patients coming to doctor's room. Therefore, it is necessary to confirm the self-consciousness symptom that the clerical workers complain of multilaterally with the actual state examination about the use of the apparatuses of offices automaton. Thus, this study was tried as th basic data for the cosultation and education for the maintenance and furtherance of the health of workers as the nurse of industry field, by confirming the contents of self-consciousness symptom attendant upon the use of the apparatus for office outomation making the financial institution in which the spparatus for office automation in most frequently used as the subject, and by examining whether there is the difference according to the subject of study, the data were collected, by using the questionnaire method, making 200 workers who consented to the study participation as the subject, among the persons who have spent over 3 months since they used the apparatuses for office automation and didn't receive the treatment in hospital due to the clerical disease for recent 3 years. The period of data collection was from Oct. 9, 1991 to Oct. 12. As for the measurement instrument about the complaint if self-consciousness symptom attendant upon the use of apparatuses fo office automation, the question item on the complaint symptom of health problem attendant upon the treatment of VDT that Kim(1991) developed and on CMI health problem and the question items on the fatigue degree due to industry were used by previous examination to 25 persons. Collected data were analyzed with the statistical method such as percentage, arithmetic mean, Person correlation coeffient, Kai square verfication, t-test, ANOVA, etc. by using SPSS/PC+ program, and the result is as follows : 1. The self-consciousness symptom that the clerical workers complained of most frequetly appeared high in 'My eyes are tired'(99.4%), 'I feel fatigue and weariness'(99.4%), 'I feel that my head is heavy5(90.0%), 'eyesight fell'(88.8%), 'I have a stiff neck'(88.8%), 'I fell pain in the shoulder'(85.0%), 'I feel cold and painful in the eyes'(76.9%), 'I feel the dry sense of eyeball'(76.2%), 'My nerves are edgy, and I an fretful, (75.6%), 'I feel pain in the waist'(73.2%) and 'I fell pain in the back'(72.8%). It emerged that the subject use the apparatuses for office automation complained of self-consciousness symptoms related to visual symptoms and musculoskeletal symptoms. 2. As for the general feature of examination subjects, the result to see the distribution by classifying into sex, age, school career, use career of apparatuses for office automation, skillfulness degree of the use of apparatus for office automation, use hours of the apparatuses for office automation per 1 day, type of business of the apparatus for office automation, rest hours during the use of apparatus for office automation, satifaction degree of business of office automation, and work circumstance, etc. emerged as follows : As for the sex of subjects, the distribution showed that men were 58.8% and women were 41.3%, Age was average 26.9. As the distribution of school career, the distribution showed that4below the graduation of high school' was 58.8%, 'graduation from junior college-university' was 35.0%, and 'over graduate school' was 6.3%. In the question to ask the existence or non-existence of experience of health consultation in connection with the work of office automation, the response that I had the consultation exprience and I feel the necessity emergerd as 90.1% And, the case that the subject who didn't wear the glasses or lens before using the OA apparatus wear glasses or lens after using OA apparatus emerged as 28.3% of whole. As for the existence or non-existence of use career of OA apparatus, the case under 3 years was highest as 52. 7%. As for the skillfulnness degree about the use of apparatus for office automation, most of them are skillful with the fact that 'common' was 44.4%, 'skill' was 42.5%, and 'unskillful' was 13.1% As for the use average hours of the apparatus for office automation per 1 day, the distribution showed that the case under 3-6 hours was 33.1%, the case under 6-9 hours was 28.1%, the case under 3 hours was 30.6%, and the case over 9 hours was 8.1% Main OA business and the use hours for 1 day showed in the order of keeping and retrieval, business of information transmission(162min), business of information transmission(79.3 min), business of document framing(55.5 min), and business of duplication and printing(25.4min). as for the rest during the use of apparatus for affice automation, that I take rest occasion demands the major portion, but that I take after completing the work emerged as 33.8%. Though the subiness gets to be convenient by the use of the apparatus for of office automation, respondents who showed the dissatisfaction about the present OA business emergd high as 78.1%. The work circumstances of each office was good with the fact that the temperature of office was 21.8, noise was average 42.7db, and the illumination was average 364.4 lx, in the light of ANSi/HFS 100 Standard. 3. Sight syptom, musculoskeletal symptom, skin and other symptoms showed the significant difference according to the extent of skillfulness of the apparatus for office automation. All the symptoms exept skin symptom showed the difference according to the use hours of the apparatus for office automation. All the question items exept the sytoms of digestive organs and the rest hours during the apparatus for office automation showed the signicant difference. The question item which showed the signicant difference from the satisfaction degree of present OA business showed the significant difference from all the question item classified into 6 groups. But, age and school career didn't significant difference from the complaint of any self-consciousness symptoms.
