  • Truncus arteriosus is one of the rare cyanotic congenital cardiac anomalies and thought to be result from complete or partial failure of trunco-conal septum. A single arterial trunk receiving blood from both ventricles supplies the coronary, pulmonary and systemic circulation. The symptoms were usually related to the degree of the pulmonary blood flow and functional status of truncal valve, and mostly appeared within the first two months of life. The prognosis is generally considered to be poor in spite of successful surgical correction. This report is a case of 13 years old female with type I truncus arteriosus, which was successfully corrected using a intracardiac Dacron tunnel graft[semilunar, 18mm] from VSD to the truncal valve, and a extra-cardiac lonescu-Shiley valved[20mm] Dacron conduit [21mm] from RV to the pulmonary artery[Rastelli operation].

  • Purpose: The inverted nipple presents many problems in both cosmetic and functional aspects. The histopathologic features of inverted nipple are that inverted nipple has less fibromuscular tissue than normal nipple, short lactiferous duct and dense fibrous tissue. Many papers have been reported for correction of the inverted nipple, however not many medical literatures has specifically described about traction method. Although traditional traction methods were using half of urine cup or lid of bottle, they were uncomfortable and incapable for wearing brassiere. Methods: We invented a simple and more natural method using a dome-shape plastic disposable lid of take-out cup. We applied new device for three patients after corrective surgery. Results: For long term follow up, all patients satisfied their postoperative status and they were comportable with the lids. Conclusion: This new method is very simple, comfortable, and effective method for traction. It also allows patients to wear the brassiere.

  • It is expected that fully-implantable middle-ear hearing devices (FIMEHDs) will soon be available with the advantages of complete concealment, easy surgical implantation, and low power operation to resolve the problems of semi-implantable middle-ear hearing devices (SIMEHDs) such as discomfort of wearing an external device and replacement of battery. Over the last 3 years, a Korean research team at Kyungpook National University has developed an FIMEHD called ACRHS-1 based on a differential floating mass transducer (DFMT). The main research focus was functional improvement, the establishment of easy surgical procedures for implantation, miniaturization, and a low-power operation. Accordingly, this paper reviews the overall system architecture, functions, and experimental results for ACRHS-1 and its related accessories, including a wireless battery charger and remote controller.

On Reliability Performance of Safety Instrumented Systems with Common Cause Failures in IEC 61508 Standard (공통원인고장을 고려한 안전제어시스템의 신뢰성 평가척도에 관한 고찰 : IEC 61508을 중심으로)

  • The reliability performance measures for low and high or continuous demand modes of operation of safety instrumented systems(SISs) are examined and compared by analyzing the official definitions in IEC 61508 standard. This paper also presents a status of common cause factor(CCF) models used in IEC 61508 and problems relating CCF modelling are discussed and ideas to solve these ones are suggested. An example with mixed M-out-of-N architecture is carried out to illustrate the proposed methods.

The Effect of Tryptophan Administration on the Plasma Free Amino Acid Concentration, Liver Microsomal Cytochrome P450 Content and Cellular Structure of Rats Consumed Reserpine and Low Protein Diet with Different Carbohydrate Contents (Tryptophan 투여가 Reserpine과 식이 탄수화물 수준이 다른 저단백식이를 섭취한 흰쥐의 혈장 아미노산 농도, 간 Cytochrome P450 함량 및 간세표 미세구조에 미치는 영향)

  • The purpose of this experiment was to compare the effects of tryptophan administration on nutritional status of female rats which consumed reserpine and 6% casein diet with different carbohydrate contents(87%, 65%, 44% respective). Final body weight, body weight gain, FER, plasma amino acid concentration and microsomal cytochrome P 450 content in liver were measured and microscopic structure of hepatocytes was observed. In low-protein diet, the higher the carbohydrate content of diet was, the lower the damage was in the rat's liver. Tryptophan administration after dose of reserpine induced more effective recovery from liver damage of rats in high carbohydrate diet group than that in low carbohydrate diet group. In conclusion, the general nutritional assessments such as final body weight and body weight gain provided better estimate of the degree of structural changes in hepatocytes than functional assessment such as plasma amino acid concentration or liver microsomal cytochrome P450.

  • This study proposes an automated pegboard utilizing the RFID system with multiple reader antennas for the rehabilitation services and the occupational therapy. The system automates the scoring by detecting the plugging correctness as well as the plugging status. It also aims to increase the patient's interest and the functional intelligence. The system was prototyped and tested for the automatic capability of the scoring the session time and success rate. The proposed system will be served as the typical example for the ubiquitous rehabilitation devices.

  • The NO$_2$gas-detection characteristics were investigated using the functional organic Langmuir-Blodgett(LB) films of Copper-tetra-tert-butylphthalocyanine(CuTBP). The optimum conditions for a film deposition were obtained through a study of $\pi$-A isotherms, and the deposited film status was confirmed by the ellipsometry measurements. It was found that at room temperature there are increments of electrical conductivities by 40 times, 25 seconds of response time and 40 seconds of response time when the films were exposed to the 200ppm NO$_2$gases. We hale observed an increase of the electrical conductivities as the density of NO2 gas increases.

  • Recently, single-domain antibodies (sdAb) are bioengineered for molecular imaging applications. Single-domain antibody, obtained from naturally occurring antibodies in camelid species and cartilaginous fish is the smallest fully functional antigen-binding antibody fragments of heavy-chain. Since their discovery, they have been investigated extensively in clinical therapeutics, monitoring and diagnostics. Their small size is important advantage for high solubility, high stability, fast blood clearance and rapid targeting. This review article summarizes the recent status of this new antibody to visualize, diagnose or inhibit specific targets of cancer.

  • This study was done to investigate the ADL differences between before and after home care. For this survey, the Barthel index, an ADU(activities of daily living) assessment, and general history questions were asked. Functional performance, i.e. ADL, was studied in a population a total of 56 men and women aged 65 and older from the city of Taejon. Among the independent subjects, women, 73 years of age and older, married status, 1-2 times taking home care per month, the case answering 'Quite' about satisfactory of home care, elderly dwelling with others and who have helper and spouse, elderly having a snack regularly, are statistically significant. Also ADL differences were found in grooming, getting in and out chair, getting on and off toilet, walking 500 meters on the level. Further studies should evaluate the activities of daily living to predict important disability-related outcomes.
