Diesel engine offers superior fuel consumption than gasoline engine of equivalent capacity. For this reason, diesel engines are widely used in heavy duty transport applications. Specially, it has been many years that exhaust gases from gasoline automobile rather than from diesel is the major object concerned by Korea and other countries, and it strongly required on the reduction techniques on harmful NOx, Soot, CO, HC. thus, this paper focused on the emission reduction and target for this paper is heavy-duty diesel engine equipped with power filter such as wet type air cleaner. In this paper, the performance, exhaust emissions(CO, THC, Nox, Soot) and noise of heavy-duty diesel engine were measured at maximum load condition and the range of 1,000~2,200pm. The smoke was measured at FAS(Free Accel Smoke) test mode.

The purpose of this study was to investigate the status of clinical nutrition services provided at tertiary hospitals and general hospitals in Korea. In total, 157 questionnaires were distributed to the departments of nutrition at hospitals on September 2013. The results of this study are as follows. The median number of beds was 607 and average length of stay was 8 days. 63.1% of dietitians had over 5 years of career experience. Nutritional screening rate was 97% in tertiary hospitals but only 67.2% in general hospitals (P¼ 0.001). The rate of equipment with computerized nutritional screening system was 100% in tertiary hospitals but 71.9% in general hospitals (P¼0.001). Hospitals with the best regarding nutritional care were hospitals accredited by JCI (Joint Commission International). On the other hand, hospitals not accredited by the JCI but KOIHA (Korea Institute for Healthcare Accreditation) showed the lowest performance rate of nutritional care. Nutrition support teams (NSTs) were established in all tertiary hospitals but in only 73% of general hospitals (P¼0.001). The rate of actively operating NSTs was 89% in tertiary hospitals but only 62% in general hospitals (P¼0.001). There is a need to provide proper standardized clinical nutrition services as a primary treatment and we observed large variations in the quality of nutritional service between hospitals. Therefore, local solutions are needed to implement nutritional programs and policies for improved service and care.

Case Report : Six-month Outcomes of Mobile Phone Application-based Self-management in a Patient with Type 2 Diabetes

( Mi Kyeong Hong ),( Young Yun Cho ),( Mi Yong Rha ),( Jae Hyeon Kim ),( Moon Kyu Lee ) 한국임상영양학회 2015 Clinical Nutrition Research Vol.4 No.3

We report the case in order to examine the effect of a mobile application program (“Diabetes & Nutrition”) developed in 2011- 2012 for self-management in patients with type 2 diabetes and to recommend important considerations when the mobile application program is developed. A 46-year-old man was newly diagnosed with type 2 diabetes in 2013 and had no complications. The height of the patient was 168 cm and the body weight was 75.6 kg. Nutrition education was conducted according to a medical prescription, and follow-up nutrition education was conducted after 3 and 6 months. After nutrition education, the patient was engaged in self-management using “Diabetes & Nutrition” program during 3 months. At 3 months, the body weight had decreased by 4.4 kg (from 75.6 to 71.2 kg), waist circumference by 5 cm (from 88 to 83 cm) and HbA1c level from 7.9% to 6.1%. Also at 3 months, the medication was reduced from from the dose of 850 mg to the dose of 500 mg metformin per twice a day. Since then, the patient did not continue to use the “Diabetes & Nutrition” because the level of blood glucose had stabilized, and the patient felt inconvenient and annoying to use the program. At 6 months, no significant change in the body weight and body composition was observed in comparison with those at 3 months. The present case demonstrates that the early use of “Diabetes & Nutrition” could be helpful for self-management of glycemic control in patients with type 2 diabetes. Developing self-management mobile application programs in the future will require strategies of how to promote continuous use of application program and self-management of type 2 diabetes.

재생 불량성 빈혈환자에서 동종 골수이식 후 난소기능 회복에 관한 연구

김미란,권동진,임용택,나종구,김장흡,류순원,정기욱,김진홍 대한산부인과학회 2000 Obstetrics & Gynecology Science Vol.43 No.3

목적: 재생 불량성 환자에서 동종 골수이식을 시행하여 높은 완치율을 보이지만 전처치로 실시되는 고농도 화학요법과 전신 방사선 요법등은 심각한 성선 기능 부전을 유발한다. 저자들은 골수 이식 후 전처치 방법에 따른 난소 기능 부전의 빈도 및 회복에 관여하는 주요 인자를 알기 위하여 본 연구를 계획하였다. 연구 방법: 재생 불량성 빈혈을 진단받고 골수이식을 받은 환자로서 단독 항암화학 요법군과 전신 방사선 조사 병합 처치군으로 나누어 이식 후 추적 관찰하였다. 지속적인 무월경시 조기폐경을 진단위해 혈중 FSH 검사를 하고 두군간의 무월경 회복 시기를 비교하였다. FSH 수치가 40mIU/ml 이상시 조기폐경으로 진단하고 호르몬 대체요법을 시행하였다. 통계 방법은 paried t-test를 사용하였다. 결과: 전반적인 난소 기능 회복율은 24명중 70.8% 였으며 모두 단독 항암 요법을 받은 군으로서 전신방사선 조사를 받은 군은 0% 였다. 회복된 군의 회복시기는 골수이식 후 중간값 7.5 개월이었다. 전처치로서 고용량 cytoxan 화학요법 시행시는 14개월까지 100%의 회복율을 보였다. 전신 방사선 조사를 시행한 7명은 모두 19-49개월의 추적관찰 기간까지 무월경 및 조기 폐경의 소견을 보였다. 난소기능 회복군과 비회복군 사이에 나이의 유의한 차이는 없었고 골수 이식시 나이와 회복 속도와는 상관관계가 없게 나타났다. 골수이식 후 12개월째 이후 월경이 돌아온 경우는 FSH가 평균 23IU, LH는 25IU을 보였고, 지속적인 무월경을 보인 경우는 FSH가 평균 67IU, LH는 89IU을 보여 유의한 차이를 나타냈다. 결론: 골수이식 성공률이 높아지면서 장기 생존율도 높아져 골수 수여자의 삶의 질을 향상시키기 위해서는 조기 폐경에 의한 여러 문제점이 예방되어야 한다. 본 연구에서 이식 후 가임기 여성의 난소 기능 회복에 가장 큰 영향을 끼치는 요인은 전신 방사선 투여의 여부이므로 이런 여성에서 골수 이식 후 자연월경을 기다리기 보다는 적극적인 평가와 저용량의 호르몬 대체요법을 시행함이 환자의 조기폐경에 의한 합병증을 줄일 수 있으리라 생각된다. Objective: Ovarian failure is often common complication by the conditioning protocol used for bone marrow transplantation (BMT). To determine the frequency of recovery of ovarian function after allo-BMT and the major factor that predict recovery, we monitored ovarian function in 24 premenopausal women Method: Twenty-four women met the inclusion criteria, which were (1) moderate to severe aplastic anemia before BMT, (2) disease-free at least 18 month after transplantation, (3) age younger than 40 years and more than 3 years after menarche at transplantation and (4) regular menstrual periods before transplantation. Recovery of ovarian function was determined by regular menses without menopausal symptom and sign. we divided conditioning regimen to two groups, Group I : cytoxan alone(n=17), Group II : cytoxan plus total body irradiation (TBI)(n=7). Results: All women became amenorrhea after BMT and the clinical characteristics were not significant between two groups. 17 patients who received only cytoxan all recovered ovarian function between 1 to 14 months(median : 7.28) after BMT. The median age at BMT of women with regained ovarian function was 26 years (range, 21 to 33) versus 30 (range, 21 to 37) for those who did not. The age at transplantation was not significant between two groups in our study and the most predictive independent factor in ovarian recovery is the presence of total body irradiation. None of women who received TBI regained ovarian function during 19-49 month follow up. Conclusion: Gonadal insufficiency due to pre-BMT conditioning is more severe in radiation based regimen than cytoxan alone. therefore, we recommend early hormone replacement therapy in radiation treated women to prevent the complication of premature menopause.

급성 림프구성 백혈병 소아에서 골수세포의 세포면역표현형 분석

황현용,김미향,홍유라,박재선 고신대학교의과대학 2006 고신대학교 의과대학 학술지 Vol.21 No.2

Background Immunophenotypic analysis of leukemic cells can be used to define specific subgroups of leukemia with different prognoses and, thereby, indicate appropriate treatment for individual cases. In this study, we analysed the immunophenotype of leukemic cells in a group of children diagnosed as acute lymphoblastic leukemia in order to assess the frequency of the different immunologic subtypes. Methods From October 1992 to January 1999, 18 patients were enrolled in this study. Conventional immunological markers were used, either associated to or specific for B, T, or myelo-monocytic cell populations. Results Among 18 acute lymphoblastic leukemia (ALL), the most predominant immunophenotype was T cell ALL (n=8) followed by early pre-B (n=6), pre-B (n =2) and B cell (n=2). CD10 (CALLA) positive ALL was found in 7 of 17 children, and were not different from CD10 negative ALL in terms of complication and survival. Eight of 12 acute lymphocytic leukemia patients, who were checked for terminal deoxynucleotidyl transferase (Tdt), were Tdt positive, whereas both of two patients with B cell ALL showed least reactivity. Tumor lysis syndrome was developed only in patients with T cell ALL (3/ 8). Conclusion T cell ALL was the most frequent immunophenotype and was occurred predominantly in male sex and older age. Although the number of the patients studied was small, there was no significant difference in survival rates between T cell leukemia and B lineage leukemia. Ongoing studies with large group of patients over longer periods need to be done to explore any difference in biological behavior and prognosis among the subgroups of ALL.

Case Report : A Case of Protein Supplement Effect in Protein-Losing Enteropathy

( Hyun Jeong Lee ),( Mi Yong Rha ),( Young Yun Cho ),( Eun Ran Kim ),( Dong Kyung Chang ) 한국임상영양학회 2012 Clinical Nutrition Research Vol.1 No.1

The objective of this article is to report improvement of nutritional status by protein supplements in the patient with proteinlosing enteropathy. The patient was a female whose age was 25 and underwent medical treatment of Crohn``s disease, an in- flammatory bowl disease, after diagnosis of cryptogenic multifocal ulcerous enteritis. The weight was 33.3 kg (68% of IBW) in the severe underweight and suffered from ascites and subcutaneous edema with hypoalbuminemia (1.3 g/dL) at the time of hospitalization. The patient consumed food restrictively due to abdominal discomfort. Despite various attempts of oral feeding, the levels of calorie and protein intake fell into 40-50% of the required amount, which was 800-900 kcal/d (24-27 kcal/ kg/d) for calorie and 34 g/d (1 g/kg/d) for protein. It was planned to supplement the patient with caloric supplementation (40- 50 kcal/kg) and protein supplementation (2.5 g/kg) to increase body weight and improve hypoproteinemia. It was also planned to increase the level of protein intake slowly to target 55 g/d in about 2 weeks starting from 10 g/d and monitored kidney load with high protein supplementation. The weight loss was 1.0 kg when the patient was discharged from the hospital (hospitalization periods of 4 weeks), however, serum albumin was improved from 1.3 g/dL to 2.5 g/dL and there was no abdominal discomfort. She kept supplement of protein at 55 g/d for 5 months after the discharge from the hospital and kept it at 35 g/d for about 2 months and then 25 g/d. The body weight increased gradually from 32.3 kg (65% of IBW) to 44.0 kg (89% of IBW) by 36% for the period of F/u and serum albumin was kept above 2.8 g/dL without intravenous injection of albumin. The performance status was improved from 4 points of ``very tired`` to 2 points of ``a little tired`` out of 5-point scale measurement and the use of diuretic stopped from the time of 4th month after the discharge from the hospital owing to improvement in edema and ascites. During this period, the results of blood test such as BUN, Cr, and electrolytes were within the normal range. In conclusion, hypoproteinemia and weight loss were improved by increasing protein intake through utilization of protein supplements in proteinlosing enteropathy.
