BACKGROUND/OBJECTIVES: Malnutrition during hospitalization is linked to increased morbidity and mortality, but there are insufficient studies observing clinical factors contributing to weight loss during hospitalization in Indonesia. This study was therefore undertaken to determine the rate of weight loss during hospitalization and the contributing factors. SUBJECTS/METHODS: This was a prospective study involving hospitalized adult patients aged 18-59 yrs, conducted between July and September 2019. Body weight measurement was taken at the time of admission and on the last day of hospitalization. The factors studied were malnutrition at admission (body mass index < 18.5 kg/m²), immobilization, depression (Beck Depression Inventory-II Indonesia), polypharmacy, inflammatory status (neutrophil-lymphocytes ratio; NLR), comorbidity status (Charlson Comorbidity Index; CCI), and length of stay. RESULTS: Totally, 55 patients were included in the final analysis, with a median age of 39 (18-59 yrs) yrs. Of these, 27% had malnutrition at admission, 31% had a CCI score > 2, and 26% had an NLR value of ≥ 9. In all, 62% presented with gastrointestinal symptoms, and depression was documented in one-third of the subjects at admission. Overall, we recorded a mean weight loss of 0.41 kg (P = 0.038) during hospitalization, with significant weight loss observed among patients hospitalized for 7 days or more (P = 0.009). The bivariate analysis revealed that inflammatory status (P = 0.016) was associated with in-hospital weight loss, while the multivariate analysis determined that the contributing factors were length of stay (P < 0.001) and depression (P = 0.019). CONCLUSIONS: We found that inflammatory status of the patient might influence the incidence of weight loss during hospitalization, while depression and length of stay were independent predictors of weight loss during hospitalization.

전 세계적으로 컴퓨터 단층 촬영 장치(Computed Tomography, CT)의 임상 적용이 환자의 질병의 조기 진단에 매우 중요하게 사용되고 있으며 사용 빈도 또한 매년 급증하고 있다. 새로운 종류의 CT 장치들이 병변을 조기 진단하기 위하여 개발되고 있다. 이 방사선 발생 장치에 의한 환자나 작업 종사자들의 방사선 피폭이 불가피 할 수도 있다. 국내에서는 CT 장치에 대한 구체적인 방사선 방어나 방사선 시설에 대한 구체적인 규정이 확립되어 있지 않다. 본 논문에서는 국내에서의 CT 사용시설에 대한 방사선 방어 시설과 사용 기준에 대한 규정 마련에 토대를 이루기 위하여 외국에서의 CT 장비에 대한 방사선 방어 및 방사선 차폐에 대한 규정을 조사하였다. 조사방법으로는 구글 검색을 이용한 특정 키워드 검색과 방사선 관련 업무를 수행하는 특정 웹사이트를 직접 검색하는 방법을 사용하였다. 검색결과 캐나다, 미국, 영국 등의 국가에서 국가의 실정에 맞는 가이드라인을 사용하고 있었으나, 아직 이중 에너지 CT에 대한 가이드라인은 없는 것으로 나타났다. 한국에서도 국내 실정에 적합한 CT 장비에서의 방사선 방어, 차폐, 환자나 작업종사자 및 일반인에 대한 방사선 피폭에 대한 가이드라인의 설정이 필요하다고 생각된다.

The Cumulus ration is 98.50% and symptoms overlapped with an average 3.57±0.1 times but in an analysis of variance of these symptoms, the gulf between males and females was not recognized as statistically significant by T-test and ANOVA. 7. Patients whose families have allergic diseases account for 90 cases(45%) : 49cases(24.50%) male and 41cases(20.50%) female. There were 4 cases (71.11 %) whose families have allergic rhinitis, 9cases(10%) of asthma, and 7.78% with allergic dermatitis. There were 61 (67.80%) cases of patients whose parents have allergic diseases; cases wherein the patient s child had allergic diseases numbered 13 (14.45%); and cases with a sibling with allergic diseases totalled 16cases (17.80%). There was no statistically significant difference in allergic disease regarding sex, parents, or siblings by chi-test. 8. Blood type: For males, type A is the most common, with 37cases(18.5%), followed by type B with 32cases(16%), type O 28cases(l4%) and type AB 13cases(6.5%).

Nowerdays, the increase of traffic accidents and old age population make the Femoral Neck Fracture(FNF) patients increase. By the improvement of education and standard of living the patients demand better medical service than before. This study is designed to give practical help for the FNF patients by observing their hospital life and establish practical nursing strategies for the FNF patients. For these purposes the Ethnographic Participant Observation was adopted. By this study is focused on the hospital life patient's view. For this end, the field study adopted orthopedic ward in the C University Hospital with 400 beds in Seoul. The object patients of the study were twelve patients. The patients experienced five stages : Embarrassment, Conflict, Stability, Independent, and Extension Stage. The findings and prepared nursing strategies are stated as follows. First, in the Embarrassment Stage they suffered embarrassment, anxiety, pain, they could not do ordinary things. The patients who accidental fractures had anxiety from unfamiliar tests and from hospitalization itself. They lamented that they could not ordinary things, and do nothing but obeying the hospital, and endure the pain. They recognized the changed environment and resigned themselves to life in the ward. In this stage, full openness by the nurses is needed. Second, the attribute of the Conflict Stage were conflict, fear, curiosity, belief, reflection. When they sign the consentment form, they experience conflicts about the possibility of complication, fear of recovery from anesthesia, curiosity about the operation procedure, post - operation state, reflection on their past life, and promise to care for their family members after discharge and keep their religious life faithfully. And they accepted the operation depending on God, believing in modern medicine, and the surgeon. Asking for their changed informations, they expected positive results from the operation. In this stage, an empathic attitude by the nurses is needed. Third, the attribute of the Stability Stage were relief, gratitude, difficulty with excretion, and pain. When they awoke from anesthesia, they felt relief because of a the end of the operation, but they experienced extreme pain, difficulty of excretion in bed. They accepted the changed environment and expected recovery. In this stage, support by the nurses is needed. Fourth, the attributes of the Independence Stage were freedom, exercise, nurturing, anxiety, and discomfort. When they ambulated and exercised, they experienced freedom. They showed exhibited weakness of the digestive organs and discomfort hospital's space, structure, and facilities, the delay of medical certificate issue the lack of prompt response by the medical agents. They ate nurturious food and felt anxiety on the end of hospital life and returning to their ordinary life. They showed the independence of overcoming their environment by increasing exercise and expected their discharges. In this stage, respect by the nurses is needed for the patients to, overcome their environment and prepare for their independence. Fifth, the attributes of the Extension Stage were pessimism, isolation, dissatisfaction, and pain. Accompanied injury and old age made their ward life extend to over seven weeks. They exhibited weariness, melancholy, skeptisis, general pessimistic feeling, and desperation caused by their isolated life. They experienced the digestive discomfort caused by the prolonged medication and psycological pain caused by long-time hospitalization. As a, result, their dissatisfaction on the human, physical, and systematic environments had been increased. They acquired critical power and sought for something to do spending their time. They expected vaguely about the returning of their ordinary life. In this stage, counseling is needed by the nurse to overcome positively their psychological, social, and physical problems. The process of the FNF patient's ward life starts from the dependent state, when they are hospitalized, and gradually progresses to self-fulfillment in order to keep independent life. As a result, the FNF patients showed "Response in Challenge" or "Adaptation in Conflict" through their experiences of social, physical, and psychological difficulties.

PET/CT 기기의 설치가 증가함에 따라 PET/CT 검사 시감쇄 보정을 위한 CT 검사 역시 증가하여 검사 과정에서 피폭 선량이 증가 되고 있어 의료 피폭의 저감 대책을 포함한 방사선 안전 관리의 체계적인 구축이 필요하다. 본 연구에서는 PET/CT 검사에서의 환자 선량 데이터베이스를 구축하여 환자 선량 저감을 위한 초석을 세우기 위해 CT 선량 측정 프로그램을 사용하여 CT를 사용한 투과 스캔 시 환자가 받는 CT의 예측 유효 선량을 비교 분석하였다. BIO40, BIO16, DSTe8 에서 $^{18}F$-FDG PET/CT 검사를 시행한 180명을 대상으로 하였다. 각 기기 별로 남, 여 30명씩 선량의 평균을 분석하였다. 자동 노출 제어 시스템으로 선량 조절 시 가장 큰 영향을 줄 수 있는 환자의 체중 별로 50 kg미만, 50-60 kg 미만, 60 kg 이상 세 집단으로 나누어 선량의 평균을 분석하였다. CT-Expo v1.7과 ImPACT v1.0을 사용하여 선량 측정을 한 값을 비교 분석하고 체중과 유효 선량의 상관관계를 분석하였다. BIO40에서 검사한 환자의 유효 선량을 CT-Expo v1.7과 ImPACT v1.0을 사용하여 예측하였을 때, 남자 환자 30명은 각각 $6.46{\pm}1.18$ mSv, $6.54{\pm}1.21$ mSv, 여자 환자 30명은 각각 $6.29{\pm}0.97$ mSv, $5.87{\pm}1.09$ mSv 이었다. BIO16 에서 검사한 환자의 유효 선량은 남자 환자 30명은 각각 $9.36{\pm}1.96$ mSv, $8.36{\pm}1.69$ mSv 여자 환자 30명은 각각 $10.02{\pm}2.42$ mSv, $8.43{\pm}1.89$ mSv 이었다. DSTe8에서 검사한 환자의 유효 선량은 남자 환자 30명은 각각 $9.36{\pm}1.96$ mSv, $9.74{\pm}2.55$ mSv, 여자 환자 30명은 각각 $9.05{\pm}2.27$ mSv, $9.19{\pm}2.29$ mSv 이었다. 각 기기에서 검사를 시행한 환자의 체중에 따른 환자의 선량을 비교하기 위해, BIO40에서 검사를 시행한 환자를 대상으로 하여 50 kg 미만, 50~60 kg 미만, 60 kg 이상으로 체중별로 세 개의 집단으로 나누어 환자 선량을 측정하였다. CT-expo v1.7로 측정을 하였을 때 각각 $6.05{\pm}1.77$ mSv, $6.18{\pm}1.05$ mSv, $6.80{\pm}1.06$ mSv이었고 ImPACT v1.0으로 측정했을 때 각각 $5.06{\pm}1.46$ mSv, $5.72{\pm}0.86$ mSv, $6.42{\pm}0.96$ mSv이었다. BIO16에서 검사를 시행한 환자를 대상으로 하여 50 kg 미만, 50-60 kg 미만, 60 kg 이상으로 체중 별로 나누어 환자 선량을 측정하였다. CT-Expo v1.7로 측정을 하였을 때 각각 $7.74{\pm}0.66$ mSv, $8.58{\pm}0.93$ mSv, $10.88{\pm}1.32$ mSv이었고 ImPACT v1.0으로 측정했을 때 각각 $6.60{\pm}0.54$ mSv, $7.45{\pm}0.69$ mSv, $9.43{\pm}1.11$ mSv이었다. DSTe8에서 검사를 시행한 환자를 대상으로 하여 50 kg 미만, 50-60 kg 미만, 60kg 이상으로 체중 별로 나누어 환자 선량을 예측하였다. CT-Expo v1.7로 측정했을 때 각각 $5.03{\pm}0.95$ mSv, $8.25{\pm}1.66$ mSv, $10.33{\pm}1.68$ mSv 이었고 ImPACT v1.0으로 측정했을 때 각각 $5.20{\pm}1.01$ mSv, $8.51{\pm}1.53$ mSv, $10.9{\pm}1.87$ mSv이었다. 체중과 유효 선량의 상관관계를 분석하였을 때 CT-Expo v1.7과 ImPACT v1.0에서 Pearson 정률 상관계수가 각각 0.743, 0.692으로 매우 강한 양의 상관관계가 있었다. 피폭 선량의 예측이 필요할 경우 이와 같은 상용화된 선량 평가 프로그램을 사용하면 Phantom 연구를 시행하지 않더라도 유효 선량의 예측 및 평가가 가능하고, CT 선량 관리를 위한 기초 자료를 수집하는데 활용 될 수 있을 것으로 생각된다.

Objectives: This was a double blinded, randomized, placebo-controlled clinical study for evaluation of safety and effective dose finding of Cardiotonic Pills$^{(R)}$ in patients with chest pain and discomfort. Cardiotonic Pills$^{(R)}$ are composed of Salviae Miltiorrhizae Radix (丹蔘), Notoginseng Radix (三七根) and Borneolum (龍腦). Major effects of Salviae Miltiorrhizae Radix and Notoginseng Radix are vasodilatation, sedation and analgesic action. Borneolum has an antibacterial effect, and can stimulate the central nervous system. All of these substances are oriental herbs that have been used for a long time in east Asia. Cardiotonic Pills fi received Investigational New Drug (IND) approval from the Food and Drug Administration (FDA) in the USA and 40 million people in the world take this pill. We performed a phase IV clinical study to confirm its efficacy and safety in patients who have probable cardiogenic or psychogenic chest pain or chest stifling. Methods: This study was planned for a multi-center clinical trial including four university hospitals of oriental medicine in Korea. This was the first time to evaluate the 'planning treatment according to diagnosis (辨證施治)' of chest pain or chest discomfort according to oriental medical guidelines. The patients who were included in this trial were adult volunteers from 20 to 70 years old who had chest pain or chest discomfort more than twice during a recent month, and we received written consent to participate in this study from all of them. After administration of Cardiotonic Pills$^{(R)}$ for 8 weeks, number of occurrences, duration, appearance and degree of chest pain or chest discomfort was observed and degree of symptoms (severity of illness, global improvement) were measured using a patient's global assessment composite scale. Results: In the patient's global assessment scale, the severity of illness of the Cardiotonic Pills$^{(R)}$ group (n=25) was 14/25=0.56 but of the placebo group (n=25) was 7/25=0.28 (p-value=0.0449). This result indicates Cardiotonic Pills$^{(R)}$have a positive effect on the symptoms of chest pain and discomfort. However, the global improvement of the Cardiotonic Pills$^{(R)}$group was 23/25=0.92, and of the placebo group was 22/25=0.88 (p-value=0.6374). The total symptom score of the Cardiotonic Pills$^{(R)}$ group was $1.68\pm20.06$, and of the placebo group was $16.76\pm72.l4$(p-value=0.2285). The number of symptom events of the Cardiotonic Pills$^{(R)}$ group was $72\pm29.78$, and of the placebo group (n=25) was $10.80\pm38.42$ (p­value=0.3660). We could not find any effects on the other factors examined besides the severity of illness, beyond the difference of standard deviations. Conclusions: Cardiotonic Pills$^{(R)}$ significantly reduced chest pain and chest discomfort in patients. Therefore, we expect that Cardiotonic Pills$^{(R)}$ will be helpful for patients with chest pain and chest discomfort not only caused by heart disease but also by other diseases.
