The purpose of this study is compare the effects of two therapeutic processes-ⅰ) conservative Myofacial Release Technique along and ⅱ) Transcutaneous Electrical Nerve stimuliation alone - on the increase in the range of motion(ROM) and on the decrease in patient's pain with chronic Neck pain. The subjects of the study were student with choronic neck pain in Daegu health university. Half of them (10) took conservative Myofacial Release Technique along and the others (10) took Transcutaneous Electrical Nerve stimuliation alone.I used 3D Motion analysis. The range of motion (ROM) in six areas-flexion, extension, left lateral flexion, right lateral flexion, left rotation, right rotation-to check the effectiveness of the two combinations of methods, measured pain with visual analogue scale (VAS) to see the effect on pain reduce. Assement was conducted to the groups before the treatment began and affer the four weeks treatment ended. This study shows that both groups demonstrated significant improvement in ROM increase and pain reduction. Flexion ROM increases were significant in MFR and TENS after treatment 2 weeks and 4 weeks. Extension ROM increases were significant in MFR and TENS after treatment 2 weeks. Right rotation ROM was no significant differences were found in MFR and TENS after treatment all weeks. Right lateral flexion ROM increases were significant in MFR and TENS after treatment 3 weeks. Left lateral flexion ROM increases were significant in MFR and TENS after treatment 1 weeks. But the others no significant differences were in MFR group and TENS group during 4 weeks.

반복성 염기서열을 응용한 PCR법인 REP-PCR을 사용하여 식중독 미생물의 분리와 동정을 위한 연구에 적용하기 위하여 주요 식중독 유발세균 5속(genus), 6종의 균주를 사용하여 실험을 실시하였다. PCR 구성성분인 MgCl₂, dNTPs, REP sequence primer, 주형 DNA의 농도를 최적화하기 위한 연구 결과, MgCl₂의 농도가 2.0mN과 2.5mN일 때, 균주들의 fingerprinting pattern의 변화가 없거나 적은 것으로 관찰되어, 모든 속의 균주를 단일조건으로 분리?동정하기 위해서 MgCl₂의 농도는 2.5mN이 최적인 것으로 결론을 내렸다. dNTPs는 50μM의 농도를 적용하였을 때부터 전체 fingertprinting pattern범위의 주 단편들을 나타내는 균주들도 있었으나 총 단편의 수가 완벽하게 나타나지는 않았고, 200μM의 적용시점에서 6종의 균주 모두 단편의 수나 강도의 변화가 관찰되지 않았기 때문에 fingerprinting pattern의 파악을 위한 목적에는 200μM의 dNTPs 농도만으로도 충분하였다. REP primer는 적용한 농도가 증가함에 따라 단편의 수와 강도가 증가하였으며 Vibrio를 제외한 5종의 균주가 2.0μM의 primer를 적용했을 때 고유한 fingerprinting pattern을 나타냈다. 주형 DNA의 양을 변화시켜 적용하였을 때 DNA 양의 비율이 2배에서 5배까지 증가하여도 초기 미량 적용 시 생성되었던 fingerprinting pattern은 많은 차이를 보이지는 않았다. 그러나 적용되는 DNA 양에 따라 단편들의 강도와 수가 약간씩 점증하는 양상을 보였다. This experiment was conducted to optimize REP(repetitve extragenic palindromic sequence)-PCR reaction conditions in order to simultaneously differentiate the five different foodborne pathogenic bacterial genera of Escherichia, Salmonella, Shigella, Vibrio and Listeria. The four major PCR cocktail components of MgCl₂, dNTPs, primers and teplate DNA were considered and their optimum concentrations were determined using six reference strains. the optimized condentration of MgCl₂ was determined to be 2.5 mM in order to obtatin a consistent fingerprinting pattern. The similar fingerprinting pattern was obtatined when REP primers and dNTPs were added up to the concentration of 2μM and 200μM, respectively. As for template DNA, the numbers of PCR fragments were not mostly affected, but their intensities were slightly increased as the concentrations of the DNA were increased from 2 times to 5 times.

Objectives : to evaluate the effects of Jetongdan, the newly developed herbal medicine, on the quality of life in patients with osteoarthritis of knee Methods : Placebo-controlled, randomized clinical trial on the 80 patients with osteoarthritis of the knee was fulfilled. After enrollment, they took medication as they enrolled. And they were asked to answer the questionnaires (Korean Health Assessment Questionnaire (KHAQ), Lequesne's functional index (LF1), visual analogue scale (VAS)) and analysed with the erythrocyte sedimentation rate (ESR) at baseline, after 4 weeks and 8 weeks of medication. Results : Total KHAQ score, some categories of KHAQ like hygiene, activities were significantly improved after 8 weeks of medication. And the change of the KHAQ score was significantly correlated with the change of VAS. But LFI, VAS, ESR level was not significantly improved, and it was considered because of the short medication period and small size of study population. Conclusion : In conclusion, Jetongdan could improve the health-related quality of life in patients with osteoarthritis of knee. Further study in the large population, in long period were recommended.

In clinical practice, restoration of primary incisors severely affected by caries continues to be a challenge. Not only are these teeth difficult to restore. but the behavior of the patient can affect treatment negatively. An acceptable restoration for maxillary anterior incisors should have matching material color, durability, adhesive cementation that is biocompatible with the pulp, easily and rapidly placed. This Paper describes two cases showing an alternative technique for the construction of completely destroyed upper incisors with polyethylene ribbons for retention and stability for the resin crowns.

As time goes up, structural capacity of members decreases in reinforced concrete structures. The deterioration of the capacity is mainly due to the poor construction, corrosion of steel bars and the neutralization of concrete due to environmental pollution, etc. This deterioration is unavoidable, thus it is necessary to develop the method for repair and retrofit of structures in order to ensure structural safety of members. The purpose of this paper is to investigate the load-deflection, ultimate strength, failure mode, and energy absorption capacity of reinforced concrete slabs subject to load experimentally for several variables and grasp the problem of concrete slabs strengthened with large diameter bolts and wire tensioning. And propose foundational research data for4 strengthening reinforced concrete slabs. The test result shows that the capacity of anchorage is controlled by bearing capacity of concrete under the anchorage or punching shear around the anchorage. And the gap between bolts and core hole must be filled to prevent slip and rotation of anchorage.

Objectives : Since the publication of Korean Medication Algorithm Project for Major depressive Disorder (KMAP-MD) in 2002, there has been a substantial need for a revision due to rapid progress in the pharmacological management for depressive disorder. We revised KMAP-MD to Korean Medication Algorithm Project for Depressive Disorder (KMAP-DD) in 2006. This paper is one of the following 4 papers consisting of Korean pharmacological algorithm for depressive disorder. Methods : The questionnaire consisted of 4 parts ; initial treatment of 1) non-psychotic depressive disorder, 2) psychotic depressive disorder, 3) treatment strategy for clinical subtypes and drug choice considering adverse effects, and 4) treatment for depressive disorder in women. It was composed of 22 questions, and each question had 54 sub-items. The questionnaire was completed by the review committee consisting of 101 experienced Korean psychiatrists. We classified the expert opinion to 3 categories (the first-line, the second-line, or the third-line). Results : For non-psychotic major depression, regardless ofthe severity of an episode, the antidepressant (AD) monotherapy was the optimal first-line treatment. SSRI, venlafaxine, and mirtazapine were the 1st-line AD. In case of a partial or no response to initial strategy, adding another AD was recommended. For psychotic major depression, combination of an AD and an atypical antipsychotic (AAP) was the treatment of choice. Among AAPs, quetiapine, rispendone, olanzapine were preferred. For non-responder to initial strategy, the next step was adding or changing AD before changing AAP. For women with premenstrual dysphoric syndrome or postpartum depression without psychotic features, AD monotherapty was a preferred strategy while for psychotic postpartum depression, combination of AD and AAP was recommended. Experts recommended various ADs according to adverse effect. Conclusion : These results suggest that the medication strategies for depressive disorder are rapidly changing and reflect the recent studies and clinical experiences.

멀티미디어 데이터베이스의 내용기반 검색은 색인 기술을 요구한다. 전통적인 데이터베이스와는 달리 데이터 항목은 기본이 되는 데이터 타입들의 속성의 집합으로 나타내어지는데, 멀티미디어 데이터베이스에 있는 멀티미디어 객체는 특징들의 수집에 의해 표현되고, 객체 내용의 유사성은 문맥과 참조의 프레임에 의존하며, 객체의 특징은 다중양식 특징 측정에 의해 특성화된다. 내용기반 이미지 검색을 단계별로 3가지 큰 작업으로 나누어 보면 해당 이미지를 가장 정확하게 특징들을 추출하는 단계와 그 추출된 특징을 효과적이고 능률적으로 저장, 검색을 지원하는 단계와 다시 이미지의 유사성을 검출해 내는 단계로 요약된다. 본 논문에서는 기존에 연구된 이미지 특징 추출들을 연구 분석하고 이미지 내용 기반 검색에 적합한 다양한 특징 추출과 유사도 검색에서의 문제점과 이에 대한 적합한 설계요건에 대해 제시한다. Content-based retrieval of multimedia database calls for content-based indexing techniques. Different from conventional databases, where data items are represented by a set of attributes of elementary data types, multimedia objects in multimedia databases are represented by a collection of features; similarity of object contents depends on context ad frame of reference; and features of objects are characterized by multimodal feature measures. Try to divide content-based images retrieval systems into three large operation, it is consist of the following three phases; extracting features that can represent images the most exactly, storing the extracted features effectively and efficiently and support retrieval, detect similarity of images. In this paper we first investigated and analyse the existing image feature extraction methods and various features extraction that adequate for content-based image retrieval and problem of similarity retrieval, we also present design of suitable demand.

徐大振,鄭鉉丞 진주산업대학교 1979 論文集 Vol.17 No.-

This experiment was carried out to determine the effect of liberal feeding of rabbit feces and residual forage on the growth of weaned pigs subject to restricted feeding in which the daily allowance of formula feed was 3% of body weihgt, compared with 4% in the controls. The rabbit feces and residual forage were to be dropped from the hutches over the pig barns. Ten pigs of the same litter were weaned at about 20㎏ of body weight and alloted in egual numbers into the control and experimental group. The growth results from feeding trial for 2 months are summarized as follows: 1. The body weight gain for 2 Months was averaged 27.0㎏ and 30.6㎏ in the control and experimental pigs, respectively, However, there was found no significant (p>0.05) difference in the body gain between both the groups. 2. The feed conversion was improved slightly in the experimental group(2.9) as compared with the control(3.3) 3. The rabbit waste and residual forage ware found considerably palatable to the pigs. 4. The liberal feeding of rabbit feces and residual forage resulted in the decrease of about 40 won in the feed cost for 1㎏ body weight gain of pigs. 5. The pigs fed rabbit waste and residual forage were found to be normal clinically.
