李金永,呂邑東 全北大學校 1981 論文集 Vol.23 No.-

韓國人類集團의 PTC (phenylthiocarbamide) 味覺에 대한 頻度의 平均値와 味盲과 血液型과의 關係를 糾明하기 위하여 그 一環으로 嶺東地方에 있어서 男女 中高等學校 學生을 對象으로 調査하여 다음과 같은 結果를 얻었다. 1. PTC 味覺은 크게 taster와 non-taster(味盲)로 區分된다. 그 中 taster는 쓴맛, 신맛, 단맛, 기타의 맛 頻度順으로 나타났다. PTC 濃度 C_1(1,300.00 ㎎/ℓ)에서 味盲의 頻度는 9.9%이었고 期待와는 달리 C_10에서는 훨씬 낮은 頻度를 나타내었다(61.2%). 쓴맛과 味盲의 頻度曲綠은 C_6과 C_7 사이에서 交叉되었다. C_13 以上의 低濃度에서의 味盲의 頻度는 거의 一定한 頻度의 傾向을 나타내었다. 2. 신맛, 단맛, 기타의 맛의 頻度는 PTC 濃度에 關係없이 男子가 女子보다 더 높았다. 특히, C_1에서의 味盲의 頻度는 男子가 9.6%, 女子가 10.6%를 나타내었고 高濃度(C_1~C_5)에서는 女子가 男子보다 PTC 味覺에 더 銳敏함을 나타내는 반면에 低濃度(C_6~C_17)에서는 그 反對現象이였다. 3. C_1에서의 血液型 A型의 味盲頻度는 11.8%, O型이 9.8%, AB型이 9.6%, B型이 8.5%였다. 이와 같이 이러한 頻度는 PTC 濃度가 낮아짐에 따라 거의 一定한 頻度의 傾向을 나타내었다. To investigate the frequency of PTC (phenylthiocarbamide) non-taster and relationship between non-taster and blood type, middle and high school students in Yeongdong population of Gangwondo province, Korea were studied. The results are as follows : 1. Most of the tasters tasted PTC as bitter. However some tasted as sour, sweet and other in the order of frequency. Frequency of non-taster of C_1 was 9.9%. That of C_10 was unexpectedly low (61.2%). The curves of bitter and non-taster was crossed between C_6 and C_7. the In lower concentrations than C_13, the frequencies of non-taster were inconsistent. 2. The frequencies of sour, sweet and other taster in male were higher than in female. Especially, the frequency of non-taster of C_1 was 9.6% in male and 10.6% in female. Whereas male was more sensitive to the high concentrations(C_1~C_5) of PTC, female was more sensitive to the lower concentrations(C_6~C17). 3. Among the non-taster of C_1, the frequency of blood type A was 11.8%, O 9.8%, AB 9.6%, and B 8.5%. This frequencies invariably changed as the PTC concentration become lower.

To control the position, velocity and torque of the ultrasonic motor, a great variety of method are proposed such as the amplitude, phase difference, frequency and so on. In the case of phase difference method, it has some advantages; it can control the direction and velocity of rotation only adjusting the phase difference and it has wide control-band. During the USM driving on adjusting phase difference, its characteristic was transformed by the change of resonance-frequency of stator, which means that the resonance frequency is different according to the phase difference. Consequently, we need to set up the most suitable driving frequency according to each phase difference.

Non-medical use of drugs to enhance performance at Olympic Games by athletes has been prohibited by the International Olympic Committee(IOC) since 1968 on medical and ethical grounds. IOC wants to protect athlete from harmful side effect of drugs due to misuse of it. It also, ethically, wants to have Games run on fair base, not fortified by performance enhancing drugs. The banned substance include stimulants, narcotic analgesics, anabolic, steroids, β-blockers and diuretics. In order to prevent the positive reaction in the doping test induced by herb medicine, this study was done on about Bojungchisheup-tang. The laboratory set up doping analyses methods to cover as many drugs as possible without sacrificing sensitivity and specificity within one procedure. Its screening method considered of four different procedures. The results were negative. According to the above results, Bojungchisheup-tang taken by athletes would show the negative reaction in the doping test. So its prescription for athletes can be given without worries of the doping test.

This Study was to investigate kinematical characteristic comparison of the gait pregnant 40weeks and after delivery 6weeks 20´s women and provide the basic data. To accomplish this study, in the first, carry out an experiment with the pregnant women in the pregnant 40weeks on the videotape, and than the second, make an experiment with the kinematic data. Kinematic data were filtered with a low-pass, fourth-order Butterworth filter with an effective cut off frequency of 6Hz. The conclusions were drawn as follows; 1. Floor contact Periods(stance and swing rate) were differed from before and after the delivery and a pregnant 40 weeks was greater than after delivery 6 weeks in the step, width, stride. Also, a pregnant 40 weeks was greater than after delivery 6 weeks in the front angular. And the other angular components were represented similar pattern. 2. In the vertical load, delivery 6 weeks was grater than a pregnant 40 weeks in the FP1(first peak) and FP2(valley). And FP3(second peak)was represent that a pregnant 40 weeks was greater than delivery 6 weeks. Also, in the horizontal shear, Fy2(progressional force)was greater than Fy1(breaking force) about time of the delivery.

In this paper, we have developed a new Force-Display system using tendon-driven method. The proposed system is based on the HIR Lab Haptic library, which calculates the real position and renders the reflecting force data to device rapidly. The system is composed of device based tendon-driving method, high-speed controller and Haptic rendering library. The developed system will be used on constructing the dynamical virtual environment. To show the efficiency of our system, we designed simulation program which can display the moving force (attaching, grabbing, rotating) on two virtual point. As the result of the experiment, our proposed system shows much higher resolution than any others.

Aims: As antiviral therapy for chronic hepatitis B (CHB) reduces therisk of hepatocellular carcinoma (HCC), ideally, no HCC should developin those who are not recommended for therapy. Yet, HCC developmentwho were outside of current treatment recommendation hasbeen reported.Methods: A simple HCC risk score was developed from 971 patientswith CHB with elevated HBV DNA levels who were outside the currenttreatment criteria due to having normal or mildly elevated alanineaminotransferase (ALT) levels (of whom 26 patients developed HCCduring follow-up). Variables included in the risk score were serumHBV DNA level (used twice), age, and sex (D 2AS score). The scorewas validated from an independent cohort of 507 patients (of whom15 patients developed HCC).Results: A 4-point risk scale was developed, with HCC risk rangingfrom 0-29.1% at 5 years for the lowest and highest D 2AS score.The D 2AS score had the highest area under receiver operating curves(AUROCs) for predicting development of HCC at 3/5 years(0.895/0.884), compared with that of risk estimation for hepatocellularcarcinoma in chronic hepatitis B (REACH-B) (0.814/0.812)and Fibrosis-4 (FIB-4) (0.759/0.702) scores, age (0.739/0.718), andALT (0.666/0.766) and HBV DNA (0.559/0.556) levels. The calculatedAUROCs to predict development of HCC at 3/5 years were 0.889(95% confidence interval [CI〕 0.796-0.983)/0.876 (95% CI,0.789-0.963) in the validation cohort, with 5-year HCC incidencerates of 0%, 0.6%, 6.3%, and 19.2% for very low, low, high, andvery high D 2AS scores, respectively.Conclusions: HCC developed in patients with elevated HBV DNAlevels and normal or mildly increased ALT levels. The D2AS riskscore can play a valuable role in risk stratification, and may beuseful to guide clinical decisions for enhanced surveillance or treatmentto reduce HCC risk in this population.

Objectives: The purpose of this study is to analyze clinical impact factors on the survival rate, and to acquire basic clinical data for the diagnosis of oral cancer, for a determination of the treatment plan with long-term survival in oral cancer patients. Materials and Methods: Through a retrospective review of the medical records, the factors for long-term survival rate were analyzed. Thirty-seven patients, among patient database with oral cancer treated in the Department of Oral and Maxillofacial Surgery at Pusan National University Hospital within a period from March 1998 to March 2008, were selected within the study criteria and were followed-up for more than 5 years. The analyzed factors were gender, age, drinking, smoking, primary tumor site, type of cancer, TNM stage, recurrence of affected region, and metastasis of cervical lymph node. The 5-year survival rate on the impact factors was calculated statistically using the Kaplan-Meier method. Results: By classification of clinical TNM at the 1st visit, there were 11 (29.7%) cases for stage I, 11 (29.7%) cases for stage II, 3 (8.1%) cases for stage III, and 12 (32.5%) cases for stage IV. The 5-year survival rate of total oral cancer patients after the operation were 75.7%, pathological TNM stage related 5-year survival rate were as follows: stage I 90.0%, stage II 81.8%, stage III 100% and stage IV 45.5%; in which the survival rate difference by each stage was significantly observed. The recurrence of cervical lymph node was the significant impact factor for the survival rate, because only 30.0% the survival rate in recurrent cases existed. During the follow-up, there were 15 (40.5%) patients with confirmed recurrence, and the 5-year survival rate of these patients was decreased as 46.7%. Conclusion: The classification of clinical and pathological TNM stage, local recurrence after surgery, and metastasis of cervical lymph node after surgery were analyzed as the 3 most significant factors.
