Although lung transplantation has been accepted as the most effective treatment for end-stage pulmonary emphysema, it is not only very hard to find a donor but also to obtain a relatively healthy lung. Furthermore, it is more difficult to match the size of the allograft, considering the height, the weight, and the size of the thoracic cage. The single lung transplatations for the end-stage emphysema have been more commonly performed than bilateral lung transplantation due to the shortage of the donors and the long-term survival rate of the single lung transplantations has shown no reasonable difference compared with that of the bilateral lung transplantationh. Recently, the functional criteria based on a comparison of predicted TLCs(Total Lung Capacities) of the donor and recipient according to height, sex and age, have been accepted at a more suitable.

Peroxisome proliferator-activated receptor $\alpha$ (PPAR$\alpha$)에 대한 본격적인 연구는 고지혈증 치료제인 fibrate류의 약물들이 PPAR$\alpha$ activator로 작용한다는 사실이 밝혀짐으로써 크게 증대되었다. PPAR$\alpha$는 fibrate를 포함한 다양한 종류의 peroxisome proiferator (PP)에 의해 활성화되는데 이들을 쥐에 단기간 투여할 경우 간의 peroxisome수와 지 방산 산화효소의 유전자발현이 증가되고 장기간 투여 할 경우 간암을 발생시키지만, fibrate류의 약물들을 고지혈증 환자에게 투여 할 경우 간암을 발생시키지 않으므로써 PP에 대한 반응성에 있어서 species difference를 나타낸다 PPAR$\alpha$는 핵에 존재하는 orphan receptor로서 PP에 의해 활성화되어 9-cis-retinoic acid receptor(RXR)와 heterodimer를 이룬 후 target gene들의 upstream에 있는 peroxisome proliferator response element (PPRE)에 결합하여 target gene들의 발현을 조절한다. 지금까지 연구된 PPAR$\alpha$의 target gene들은 모두 lipid와 lipoprotein 대사를 조절하는 것으로 알려져 있으며, 이러 한 결과들을 기초로 lipid 대사 및 energy balance와 관련된 질병들 - 동맥경화증, 관상동맥질환, 비만, 제 2형 당뇨병 등에서 PPAR$\alpha$의 역할이 집중적으로 연구되고 있다. PPAR$\alpha$가 활성화되면 lipoprotein lipase와 HDL이 증가되고 apo C-III가 감소됨으로써 동맥경화증에 대한 예방적 기능을 나타내고, 몸무게를 감소시킴으로써 비만을 방지할 수 있으며, 인슐린 감수성을 증가시켜 제 2형 당뇨병의 치료효과를 가지는 것으로 보인다. 그러나 PPAR$\alpha$-null mouse에서는 이러한 효과들이 나타나지 않는 것으로 보아 이들 질병에서 PPAR$\alpha$가 중요한 역할을 하는 것으로 생각된다.

An 18-month-old intact male Cocker Spaniel dog weighing 7.7 kg was referred with a 2-week history of severe regurgitation. Based on the screening examination and fluoroscopy, this patient was diagnosed as having esophageal dysmotility. Treatment with mosapride and feeding small amounts of canned food frequently in an elevated position resulted in a successful outcome. The severe regurgitation improved, and the esophageal transit time improved from 18 sec to 8 sec. This is the first case report describing the diagnosis and clinical management of esophageal dysmotility in a young dog in Korea.

In this paper, we introduce a case study of developing a miniature humanoid robot which has 16 degrees of freedom, 42 cm heights, and 1.5kg weights. For easy implimentation, the integrated RC-servo motors are adopted as actuators and a digital camera is equipped on its head. So, it can transmit vision data to a remote host computer via wireless modem. The robot can perform staircase walking as well as straight walking and turning to any direction. The user-interface program running on the host computer contains a robot graphic simulator and a motion editor which are used to generate and verify the robot's walking motion. The experimental results show that the robot has various walking capability including straight walking, turning, and stairs walking.

Smart mobility is rapidly emerging as a next-generation eco-friendly transportation system, and the market is booming every year. However, due to the characteristics of the devices that use electricity as the power source, the motor and the battery are different from the performance and actual performance indicated by the manufacturer depending on the user's weight and driving environment. Therefore, The frequency of the overload is increased and the failure and damage of the device are increasing. In this paper, we propose an application that provides personalized recommended driving guidance and overloaded driving situation notification at the actual driving separately from the recommended driving provided by the manufacturer after measuring the driving environment of the user, so as to prevent malfunction and damage of the smart mobility device, To ensure safety.

수술 시 시행되는 마취 과정에서 저혈압, 빈맥 등의 합병증이 다양한 정도로 발생한다. 이는 환자의 수술 후 심근경색이나 급성 신장 손상과 같은 심각한 합병증을 야기할 수 있으며 이러한 합병증들은 환자를 사망에 이르게 하는 원인이 되기도 한다. 본 연구에서는 머신러닝 기법을 활용해 전신마취 유도 중 저혈압 발생 환자를 예측하고자 한다. 순천향대학교 부천병원에서 수집된 207명 환자의 데이터를 이용하여 저혈압 발생 환자를 탐지하는 모델을 구축하였다. 의무 기록정보에 나타난 성별, 나이, 몸무게, 키, 신체적 상태 정보와 마취 유도 단계의 생체 신호 정보를 이용하였다. 신체적 상태 정보를 제외한 전체 피쳐를 모두 사용하였을 때, 탐지 정확도 68.06%, 관련 논문을 바탕으로 중요 피쳐만을 사용하여 실험하였을 때, 정확도 71.53%였으며, 환자의 신체적 상태 피쳐를 포함하여 실험하였을 때, 정확도 75%로 가장 우수한 결과를 얻었다.

In this paper, we propose a system that recommends the appropriate menu using the fuzzy rules and the case database. The rules are defined by using the user's body information such as height and weight and these information is often vague. Due to its fuzziness, we use the fuzzy logic to represent the information. In our system, it firstly gets the body information for computing the BMI (Body Mass Index) values. Then it combines the muscle mass factor and BMI values to make a fuzzification for calculating the obesity rate. It finally recommends the most relative menu by comparing with the user's obesity rate from each cases in the database. We implement the system on the Android platform and show that our proposed method can achieve reasonable performance through the various experiments,

The purpose of this study was to development a uniform shirt for high school boys aged 16-18 in the 7th Human Dimension Survey data of Size Korea. The upper body was analyzed to classify the upper body shape and to understand the characteristics of the body by type. Through this, we wanted to obtain the basic data necessary for the development of school uniform shirts. For data analysis, SPSS Ver. 26.0 program was used. In high school boys, there was no significant difference in height by age, but in width, thickness, length, circumference, shoulder slope, and weight, there were significant differences by age. The upper body types were categorized into four types: long shoulder skinny type, long upper body obese type, short shoulder normal type, and long shoulder normal type. Based on the size and body type data extracted from this study, it is thought that the development of uniform shirts with excellent fit should be realized through practical fashion development and construction of a size system.

A 5 month old Korean domestic short haired male kitten (weighing 1.7 kg) was presented with primary complaints of upper respiratory disease (URD) signs and skin ulceration and edema on face, feet and footpad with lameness. Diagnostic test revealed leukopenia, lymphopenia, pancreatitis and feline calicivirus (FCV) infection. Diagnosis of virulent systemic FCV (VS-FCV) was made on clinical signs, isolation of calicivirus via PCR and exclusion of other causes of acute upper respiratory disease. Therapeutic strategies were directed to lessen URD signs and to treat secondary bacterial infection and antiviral infection. One month after this therapy, skin lesions on face and feet and URD signs were much improved, although the lameness persisted mildly. To author's best knowledge, this is the first case reporting VS-FCV infection in a kitten in Korea.

This study is aimed at identifying the association of commuting behavior with health for workers in the Korea Capital Region. The study surveyed a total of 1,285 commuters whose major work is deskwork-oriented; the authors obtained their health status on body form, blood pressure and cholesterol as well as their commuting behavior. The measures of the latter were comprised of a main commuting mode, a use term, out-of-vehicle time, total travel time, transit transfer, and alternative mode in order to identify the amount of physical activity obtained through commuting behavior. The results indicate that non-automobile commuters are positively associated to improve their health status, as compared to car commuters. Specifically, bus commuters and walkers had decreased weight, blood pressure, and cholesterol, while rail commuters are only correlated to relieving cholesterol. In addition, the measures for health are improved as out-of-vehicle time increases. For commuters who drive to work, their health status tends to be worse.
