This case demonstrates the rare occurrence of a radiolucent temporary resin bridge aspiration in adults while they are in a conscious and awaken state and the resultant formation of inflammatory polyps. Although no unique findings were noted in a chest x-ray, careful history taking accompanied by physical examinations can lead to clinical suspicion of foreign body aspiration in an earlier stage. Moreover, flexible bronchoscopy is a tool useful not only for the evaluation process but also for managing the aspirated foreign material.

Purpose: The purpose of this study was to know the cause of the tenderness at pes anserinus. Materials and Methods: Out of 24 patients with tenderness at pes anserinus, 23 patients were female and 1 patient was male, and their average age was 65.9 years old. We checked the tenderness at pes anserinus by history taking & physical examniation and then, checked the pes anserinus for the presence of bursitis by US in outpatient clinic. With no evidence of bursitis by US, we injected steroid-lidocaine mixture intraarticularly and checked whether the tenderness disappeared after 2~3 minutes. Results: There was no case with bursitis at pes anserinus by US. The tenderness at pes anserinus diminished in 2-3 minutes after the intraarticular injection of the steroid-lidocaine mixture. After 6 weeks follow up, 16 patients(66.7%) had little or no tenderness at pes anserinus. 8 cases had the recurrence of tenderness recurred, 4 cases underwent arthroscopic operation on the meniscal tear, and 1 case underwent total knee arthroplasty. All cases underwent any operations had the tenderness at pes anserinus disappeared. The others 3 cases did not undergo total knee arthroplasty despite of radiologic obliteration of knee joint adequate for Kellgren-Lawrence grade IV. Conclusion: Without the bursitis at Pes Anserinus, patients the osteoarthritis may have the tenderness due to the referred pain.

Clonorchiasis should be realized as an important public health problems in Korea by their wide distribution, high prevalence rate and heavy infection intensity. This study was designed to obtain the infection rate, contributing factors as well as the behavior of infected persons among the factory workers in Pohang area where that parasite still remains as a problem. Study was undertaken from September '86 to October '87. Clonorchiasis skin test was performed for 3180 factory workers, and stools of skin test positive reactors were examined. Praziquantel was prescribed to stool examination positive persons for clonorchis sinensis ova. After one year. stool examination was repeated for them who received medicine. At the same time. a structured questionnaire was given and the results were analyzed and compared with control group. The results of this study are summarized as follows; 1. The infection rate of Clonorchis sinensis. 1) Clonorchiassis skin test positive rate was $26.2\%$ (834/3180). 2) Stool(Clonorchis sinensis ova) positive rate among skin test positive reactors was $21.6\%$ (129/598) All 129 infected persons were male. 2. Contributing factors of Clonorchis sinensis infection. 1) The chance of infection was higher in low-educated peple(p<0.01) 2) Stool(Clonorchis sinensis ova)positive rate was higher among the persons who reside near the riverside now(p<0.01), or among the persons who long history of riverside residence(p<0.01) 3) The infection rate was higher in thoes who like sliced raw fresh water fishes than in those who like cooked fishes(p<0.05). 4) Correct answering rate for questions about the cause and route of Clonorchis sinensis infection was low in infected persons. 5) The infection rate was lower among those who had experience of previous clonorchiasis test(p<0.01). 6) Family members of infected persons show higher rates of infection(p <0.01). 3. Treatment effect and compliance of infected person to treatment. 1) After one year, negative stool conversion rate was $85.4\%$. 2) $70.8\%$ of infected persons took the medicine; Only $3.1\%$ of them consulted to physician to know the medication effect; As many as $29.4\%$ of them continued to consume raw fresh water fishes. As a conclusion, City of Pohang area, Hyung San River in the center, is an endemic area of clonorchiasis. Current clonorchiasis control system seemed to be ineffective; many of the skin test positive group did not submitted their stool for examination; only $70.8\%$ of infected persons took the medicine even though the drugs were given free of charge; $29.4\%$ continued to consume raw fresh water fishes after taking medicine. Therefore. proper education program should be provided to improve the compliance to treatment. Follow-up for infected cases is mandatory to prevent waste of restricted budget.

A 47-years-old woman presented with a 2-month history of a dry mouth and dry cough. The patient had been taking medication for Sj$\ddot{o}$gren's syndrome for approximately 7 years. The chest radiography showed multiple cystic lesions and a hazy density in both lower lung fields. The HRCT showed a diffuse ground glass like appearance and multiple variable sized cystic lesions in both lung fields. After medication, the symptoms were aggravated. Bronchoscopy was preformed with a transbronchial lung biopsy. The biopsies showed an infiltration of lymphocytes, neutrophils, monocytes and histiocytes through the interstitial space of the alveola and a widening of the alveolar septa. However, the histological findings of the cysts were not obtained. Sj$\ddot{o}$gren's syndrome is a slowly progressive inflammatory autoimmune disease, which is characterized by lymphocyte mediated destruction of the exocrine glands, with pulmonary involvement in approximately 19-65%, High-resolution CT is a sensitive technique for assessing the pulmonary involvement in patients with Sj$\ddot{o}$gren's syndrome. Although a lung biopsy is not always necessary for establishing a diagnosis of an interstitial lung disease in Sj$\ddot{o}$gren's syndrome. A lung biopsy may reveal a wide spectrum of changes ranging from a mild inflammatory response to end stage fibrosis with honeycombing. Because of the predominantly peribronchiolar inflammatory infiltration and inspissated secretions the cysts were suspected to have been formed by the ball-valve phenomen. However, no definite evidence was obtained.

Consider a typical wireless sensor network in which stem nodes form the backbone network of mesh topology while each stem node together with leaf nodes in its vicinity forms a subnetwork of star topology. In such a wireless sensor network, we must heed the following when we design a MAC scheme supporting the packet delivery from a leaf node to a stem node. First, leaf nodes are usually battery-powered and it is difficult to change or recharge their batteries. Secondly, a wireless sensor network is often deployed to collect and update data periodically. Late delivery of a data segment by a sensor node causes the sink node to defer data processing and the data segment itself to be obsolete. Thirdly, extensive signaling is extremely limited and complex computation is hardly supported. Taking account of these facts, a MAC scheme must be able to save energy and support timeliness in packet delivery while being simple and robust as well. In this paper, we propose a version of ALOHA as a MAC scheme for a wireless sensor network. While conserving the simplicity and robustness of the original version of ALOHA, the proposed version of ALOHA possesses a distinctive feature that a sensor node decides between stop and continuation prior to each delivery attempt for a packet. Such a decision needs a stopping rule and we suggest a Bayes stopping rule. Note that a Bayes stopping rule minimizes the Bayes risk which reflects the energy, timeliness and throughput losses. Also, a Bayes stopping rule is practical since a sensor node makes a decision only using its own history of delivery attempt results and the prior information about the failure in delivery attempt. Numerical examples confirm that the proposed version of ALOHA employing a Bayes stopping rule is a useful MAC scheme in the severe environment of wireless sensor network.

Nuclear issue is a good example showing globalization of the international regime. The history showed nuclear weapons may cause the extinction of human races when the first nuclear bombs fell down to Japan in August, 1945 and people became increasingly eager to achieve peace. Military buildup for national security is a matter of existence in the international society. However, disarmament or arms control to secure international peace and safety which is also the purpose of the Charter of the United Nations may be the most important task for us to realize peace of the mankind. Today, disarmament, together with amicable settlement of international conflicts and collective security system, is an important means to maintain and promote international peace and safety. It might be our permanent task to realize complete disarmament but, as the Preamble of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) expressed general and complete disarmament, the international society has clarified its effort for complete disarmament. Thus, taking a look into the international regime on the nuclear issue and progress related to the nuclear issue in North Korea, the study was intended to introduce the globalization of the nuclear issue, review the international effort for nuclear disarmament based on the concept of the 'common heritage of the mankind' and with respect to the United Nations Committee on the Peaceful Uses of Outer Space (COPUOS) and controls over nuclear weapons, and then evaluate the North Korean nuclear issue, which is in direct relation with South Korea and international laws, in terms of the space law and disarmament acts. The collective security system along with policies to prevent dissemination of nuclear weapons should also be emphasized and implemented to cope with the North Korean nuclear issue.

Lymphangioleiomyomatosis, a rare disease in women of childbearing age, is the result of benign nodular hypertrophy of the smooth muscle of the lypmhatics and other tissues of the abdomen and thorax. We report a 36-years-old woman with pulmonary and retroperitoneal lymphangioleiomyomat.osis who responded with hormone treatment. She developed vaginal pruritis and a pelvic ultraound was done given her significant past medical history. Ultrasound examination demonstrated a large mass in the right side of her pelvis. Therefore she was admitted to St. Michael's Hospital in Toronto for laparoscopy. Result of cytology was to be consistent with the diagnosis of retroperitoneal lymphangioleiomyomatosis. High resolution CT sacn of the thorax demonstrated multiple small cystic lesions, without associated nodularity compatible with a diagnosis of pulmonary lymphangioleiomyomatosis. She has been taking Provera tablets 100mg po tid since Dec. 15, 1993. We have given her a prescription for Depo provera 500mg IM monthly since she came back to Korea. and made arrangements for regular follow up monthly. We performed chest X-ray, CT of chest(high resolution), abdomen and pelvis, pulmonary function tests and arterial blood gas analysis. Chest X-ray and CT findings showed no significant change since July. 20, 1993.

The purpose of this study was to test whether Yoga exercise, one of muscle relaxation, helps to relieve chronic low back paln. Sample were selected from nurses who were worked at K medical center in the period from March 18 to April 23, 1996. The sample size was fifteen. The research design was one-group pretest-posttest design. To test the major research question, this study had the following procedure. The pretest included measuring individuals' degree of pain and discomfort depending on the scope and types of an range of motion, and their pain by their activity of daily living(ADL). The treatment was conducted twice every other week. The reason why this study had twice observations was to control history effect and maturation which treat internal validity in the research design of this study. In this research design, a treatment was to expose Yoga exercise to samples. The exercise was taken in 30 minutes per day for four days in a week (Two consecutive days and twice every other day). The posttest included re-measuring the individuals' the degree of pain and discomfort, and their pain by their ADL. Several hypotheses concerning effect of Yoga exercise was analyzed by the paired t-test, comparing the difference scores between pre and post tests. The results of this study was as follows. The first hypothesis that the post-treatment group taking the Yoga exercise had the pain score lower than the pre-treatment group was supported(t=3.31, p=.005). The second hypothesis that the discomfort score of the post-treatment group had lower than does that of the pre-treatment group was supported(t=2.75, p=.016). The third hypothesis that the post-treatment group had the pain score by ADL lower than does the pre-treatment group was supported(t=5.52, p=.000). In summary, this study examined the effect of a yoga exercise, one of muscle relaxation, on those who were suffered from chronic low back pain. The effect measured by the degree of pain and discomfort with a visual analog scale was statistically significant. The degree of pain according to postures in ADL also showed statistical significance. These findings showed that a yoga exercise was effective to alleviation of chronic low back pain. A pretest-posttest control group design, however, needs to get more accurate results since the design satisfies Internal validity. Consequently, yoga as an exercise cure improves an interaction between muscles and articulations, and performance of ADL for those suffered from chronic low back pain. Furthermore, this positive impact may be an effective method as nursing intervention for their physical, mental, emotional, social, and psychological recovery.

The name of a place represents the social and political power relations as well as showing a certain physical space. In particular, the East Sea is not only a representative name of areas represent our country, but also the name of place being in competition with the Sea of Japan internationally. Korea is committed in many ways to spread the name of East Sea in the international community, and gradually expand its name power. The purpose of this study was to investigate the names used in the newspapers and broadcasting in Francophone countries except France by analyzing the newspaper articles and broadcasting contents, and to illuminate how the names of the East Sea produced in France, and the discussion about the names were diffused in Francophone countries and what kind of influence they had on those countries. This study selected Algeria in North Africa, Belgium and Luxembourg in West Europe, and Quebec in Canada for the research areas. As a result, while Algeria in North Africa and Luxembourg are showing inhospitality to the name East Sea, Belgium and Quebec are taking a flexible attitude toward this name. In general, most Francophone countries are provided with press releases from AFP in France. Even in same article provided by AFP, The result shows that some media stick to use the name Sea of Japan solely, and others demonstrate a will to use both name East Sea and Sea of Japan simultaneously. This study was able to show that the diffusion and spread of the place name was significantly influenced by social, political interests and powers, the mess geopolitics in pop cultural materials.

Both genetic and environmental factors play important roles in the pathogenesis of Parkinson Disease(PD). The contribution of many environmental factors including dietary factor remains unproven. The purpose the study was to investigate the dietary habits, nutrient intake and dietary quality of Korean PD patients according to the duration of disease. PD patients were recruited from K and S university hospitals from May 2005 to January 2006. This study was carried out after approval by the Institute Review Board(IRB). British Brain Bank criteria was used to diagnose PD. The subjects were classified into 2 groups based on the duration of PD: <25 months and $\geq$25 months groups. General characteristics, anthropometric measurements, food habits and dietary intakes were investigated. The results of this study were as follows: 1) The mean age of <25 months group($66.9{\pm}8.0$ yr) was significantly higher than that of $\geq$25 months group($62.2{\pm}8.8$ yr)(p<0.05). No significant differences were found for academic background, occupation, living status and social activity, however, numbers of diseases, exercise and family history of PD were significantly different. 2) Anthropometric measurements were not different between the two groups. 3) The frequency of taking snacks was significantly higher in <25 months group and the amounts of alcohol consumption were significantly higher in $\geq$25 months group. 4) Daily intakes of most nutrients were very low compared with DRI. 5) The MAR score was significantly lower in <25 months group(p<0.05;) however, the scores of DVS, DDS and DQI were not significantly different. As a conclusion an overall nutrient intake and dietary quality of the Parkinson's Disease patients need to be improved regardless of duration of the disease and a well-balanced diet should be emphasized.
