The subject of Abdominal syndrome in the field of Jin Kui Yao Lue takes a quarter of the whole research quantity, and has greatly contributed to the development of diagnoses due to the well-growth of syndrome differentiation through 'the differentiation of symtoms and signs based on prescriptions'-centered abdominals syndrome. Since then, while the diagnostic has been developed mainly in the field of pulse feeling and the inspection of the tongue, application of the abdominal diagnostic has not been continuously improved because of special historical and social environments. Recently, since interest in the differentiation of symtoms and signs based on abdominal syndrome has been raised by emphasis of Oriental diagnostic methods and medical treatment which have led to the study of Abdominal Syndrome in Jin Kui Yao Lue. The following is the results of the study. 1. Jin Kui Yao Lue abdominal syndmme is categorized into all abdominal symptoms Epigastric symptoms, Hypochondrium symptoms, and Lower abdomen symptoms. 2. Subjective symptoms and Objective symptoms have been found in Abdominal syndrome, and Subjective symptoms have been more often than Objective symptoms. Both of the symptoms have been found more to co-exist in abdominal syndromes. 3. More cases of fullness of abdomen symptoms in All abdominal symptoms, a smaller number of cases in Taiyang disease, Yangming disease, disease involving all three yang, Tayin disease and Jueyin disease have been found, but there have not been found in Shaoyin disease. 4. More cases of Epigastric fullness and rigidity in Epigastric symptoms, Epigastirc throbs in Palpitation symptoms, and sense of fullness-in-chest in Abdominal syndrome of chest and hypochondrium have been recognized. 5. Any regularity caused by abdominal symptoms has not been identified. 6. Diagnosis of the abdomen caused by abdominal symptoms has been identified in Epigastric fullness, Epigastric pain, Epigastric procrastination, Epigastric throb, fullness of abdomen and distension of lower abdomen.

Ogapi(Acanthopanax senticosus) is being used for a tonic in the oriental medicine from ancient times, Even though it being used frequently for a tonic in the clinical medicine, basic study to make sure the mechanism of its action is the rare. Therefore, in this study, the author tried to know the effects of ogapi on the innate and specific immune systems in association with antitumor activity. The results obtained in this study are as follows: 1) Ogapi increased the phagocytic activities of murine peritoneal macrophages in vivo and in vitro. 2) Ogapi enhanced the production of such reactive oxygen intermediates as superoxide and hydrogen peroxide from the macrophages in vivo and in vitro. 3) Ogapi enhanced such humoral immune responses as hemagglutinin and hemolysin formations. 4) Administration of ogapi increased the number of rosette forming cells in the spleen. 5) Ogapi decreased the contact hypersensitivity against dinitrofluorobenzene. 6) Ogapi showed cytotoxic activity against human leukemia cell line (K562) 7) Ogapi increased the ratio of helper T cell versus suppressor T cell by increasing CD4^+ T cells and decreasing CD8^+ T cells. The above results show that ogapi increase the host antimicrobic and antitumor activities by the action on individual innate and specific immune systems in vitro. So this is considered as experimental results back up powerfully that ogapi can be used for a tonic in such a case when administered to a person lacking vital energy.

The goal of this study is to propose the improved scheme that prevents the workers against musculoskeletal disorders. A questionnaire and an ergonomic assessment method were adopted to analyze the symptoms of workers' musculoskeletal disorders, and an analysis of working postures and a quantitative assessment on various processes were performed to find out harmful factors of workplace. Based on the result of questionnaire that was obtained from the workers having the symptoms of musculoskeletal disorders, it was analyzed that 371 workers corresponding to 80.1% out of the total respondents suffered or currently suffers from an ache, tingle, and numbness. The result of QEC analysis shows that the waist and the shoulder are highly exposed to the risk of musculoskeletal disorders. In case of TRIM process of gluing glass, the degree of risk on the hands and wrists is high due to repeated operation of 1200 times per day in a pinch-grip posture. The result of RULA analysis shows that the factors of muscle and weight is comparatively less risky than those of a working-posture. It also shows that the risk of musculoskeletal disorders is highly influenced by a immoderate bend of shoulder, wrist, and neck. The result of OWAS shows that, with the exception of one posture, the highest level of "4" was recorded on all of working postures. This means that the relevant working posture is seriously injurious to musculoskeletal system Therefore, the immediate improvement of facilities and the fulfillment of prevention pro-gram of musculoskeletal disorders are required in relevant workplace.

This paper is investigated on the study of uniformity improvement and electrical characteristics for the 1×128 diode array used Hg^0.7Cd^0.3Te. The electrical characteristics were measured for the device manufactured by several different annealing processes and temperatures being discrepant from existing method of annealing processes and temperatures. The results of uniformity were improved from 60∼80[%], the rate of existing uniformity, to 99[%]. The results obtained from analyzing and examining the characteristics of current-voltage(I-V) and capacitance-voltage(C-V) are following. First, the reverse current show 6[㎁] or so. It is seemed to be resulted from the decrease of direct tunneling and trap tunneling of the device. Second, when the input bias voltage is zero, the maximum value of reverse resistance show 12[GΩ], and the mean value of reverse resistance show 5[GΩ]. Third, it is shown that the voltage of the maximum value of resistance is shifted 0.1[V] to the reverse direction.

한의학의 診斷에는 望·聞·問·切의 四診法과 여러 가지의 辨證體系, 즉 氣血津液辨證, 臟腑辨證, 六經辨證, 衛氣營血辨證, 三焦辨證, 四象體質辨證 등이 응용되어 지고 있으며, 또한 그와 더불어 症狀·證候鑑別診斷法등이 선택적으로 활용되어 지고 있다. 이러한 廣範圍한 診斷方法가운데 切診은 손가락 및 손바닥의 感覺을 運用해서 一定部位를 觸指, 按壓하는 檢査方法으로써 切脈診과 按診으로 크게 나눌 수 있다. 이중 按診이란 손을 사용하여 직접 환부에 觸摸 按壓하여 이상변화를 알아내고 나아가서는 疾病의 部位와 性質과 病情의 輕重 등의 內部의 變化와 體表의 反應을 觀察하여 重要한 辨證資料를 얻는 診斷方法의 한 種類를 말한다. 또한 按診에는 按肌表, 按手足, 按胸腹,, 按兪穴診法등을 들 수 있다. 背兪穴의 診斷法은 經絡이라는 反應路를 通하여 體表에 發現되는 壓痛, 自發痛, 緊張, 弛緩, 硬結 및 條索狀物 등의 現象으로 부터 內部臟器의 病變을 診斷하는 方法이다. 이에 著者는 按診의 內容과 方法을 연구하면서 十二經脈의 始動病 所生病을 알아보고 穴位診斷의 方法 및 注意點등을 아울러 정리하므로써 다음과 같은 結論을 얻었다. 1. 兪穴운 各 臟腑의 邪氣가 注入하는 곳으로 臟病 寒症 虛症의 의미를 내포한 陰性病症 治療에 重要한 곳이다. 2. 兪穴의 觸診 卽 母指로서 脊椎棘突起 左右側을 按壓하여서 上向이나 下向으로 推壓指하면 棘突起의 突, 陷凹, 緊張, 弛緩 및 壓痛의 出現部位에 따라 系統別 疾患을 判斷할 수 있다. 3. 實際 臨床에서 患者의 診斷 治療에 있어서 背部按診은 重要한 診斷의 한 領域으로 빠뜨리지 말고 꼭 參考하여야 할 것으로 思料된다. 4. 臟腑疾患에 대한 診斷方法의 多樣化와 治療領域의 擴大 및 治療率의 上昇을 위해 背部兪穴의 正確한 認識과 兪穴按診을 통하여 正確한 診斷이 되었으면 한다. The diagnosis in Oriental medicine is done by inspection, auscultation and olfaction, interrogation, four diagnostics of pulse feeling and palpation, and various system of identification like identification according to Qi(vital energy), Xue and body fluids, identification according to fair principles, identification according to principles of Wei, Qi, Ying and Xue, identification according to SanjiaoIthe triple heater), identification accordmg to four type physical constitution. Sometimes, symptoms and diagnosis techniques according to symptoms is selectively applied for the Qagnosis. Among them the pulse feeling and palpation diagnosis technique using the sense of finger and palm of the hand is divided into feeling of pulse and palpation and pressing maneuver. Pressing maneuver is a diagnosis technique pressing and rubbing the affected part in order to attain data of identification including inside and outside condition of the body with regard to the nature, condition and relative seriousness of disease. There are palpation of the slun, palpation the hand and foot, palpation the chest and the abdomen, palpation shu points in pressing maneuver. The diagnosis of the Back Shu points is a technique to examine the change of disease condition from pressure ache, spontaneous ache, tension, relaxation, soliddication revealed through channels and collaterals. I investigates starting disease and an attack of disease of twelve pulse and pulse condition through the study relative to the substance and technique of pressing maneuver, and adjusts diagnosis techniques of a region for acupuncture and matters to be attended. The conclusions are as follows. 1. The Shu or stream points in which pathogenic factors go are important to medical treatment of dormant diseases like bowels disease, cold symptom complex and insufficiency symptom complex. 2. Disease classified by system is diagnosed by the condition of process part like protrusion, cave-in, tension, relaxation, pressure ache through palpating the Shu or stream points, that is pressing upward or downward left and right sides of the backbone process by hands. 3. In real clinic pressing maneuver of one s back side is very important to patient's diagnosis treatment. Thus, pressing maneuver of one s back side have to be done without omission. 4. Diagnosis must be accomplished through the perception about the diversity of diagnosis technique of bowels disease, the exact knowledge about pressing maneuver of one s back side for enlargement of treatment range and rising of treatment rate, and pressing maneuver of the Shu or the stream points.

이문환,박래준 대구대학교 특수교육재활과학연구소 2004 再活科學硏究 Vol.22 No.1

근막이완술(myofascial release, MFR)과 테이핑치료가 채찍손상을 당한 환자의 통증수치에 미치는 영향을 평가하기 위해 치료전, 1회치료후, 2회치료후, 3회치료후, 4회치료후, 그리고 5회치료후 총 6회 동안 통증수치를 측정했으며, 두 군간의 효과를 검정하기 위하여 본 연구자들은 온습포, 전기치료, 그리고 근막이완술을 받은 25명을 한 군으로, 두 번째 군은 온습포, 전기치료, 그리고 테이핑 치료를 받은 25명으로 구성되었으며, 연구결과에 대해 살펴보면 근막이완술을 적용한 군의 치료횟수별 통증은 유의하게 감소하였으며(p<0.05), 테이프를 적용한 군의 치료횟수별 통증 역시 유의하게 감소하였다(p<0.05). 하지만 두 군간의 통증감소 비교에서는 근막이완술군에 비해 테이핑군이 더 유의하게 감소하였다(p<0.05). 이상의 결과가 암시하는 것은 채찍손상으로 인한 경추부 통증환자를 치료하는데 있어서 테이핑 치료가 효과적인 것으로 사료된다. 따라서 임상에서 채찍증후군 손상으로 인한 환자의 경부통증 감소를 목적으로 적절히 시행할 수 있는 한편 경부주위에 발생하는 모든 근골격계질환자의 통증감소 목적으로도 사용될 수 있는 만큼 급성 경부통증환자를 만성화시키지 않고 빠르게 회복시킬 수 있어 환자에게 다가가는 치료사의 신뢰도 향상에도 기여할 수 있을 것으로 사료된다. The purpose of this study was to assess the effectiveness of myofascial release(MFR) technique and Taping therapy on the pain level in whiplash injury patients. Pain level were assessed prior treatment, after first treatment, after second treatment, after third treatment, after fourth treatment, and after fifth treatment. All 6 times were calculated pain level. To find out the effectiveness of MFR and Taping therapy, we were divide two groups. The one group was consisted of 25 patients that were treated with H/P, electrical therapy and MFR, and the other group was consisted of 25 patients that were treated with H/P, electrical therapy, and Taping therapy. The results were as follow: 1. There were statistical significance on the pain level in MFR group during all treatment periods(p<0.05). 2. There were statistical significance on the pain level in Taping group all during treatment periods(p<0.05). 3. Taping group had more statistical significance than MFR group on the pain level during all treatment periods(p<0.05). Consequently, this study suggest that Taping therapy has a very effectiveness to the whiplash injury patients.
