About the steel pipe built-up scaffolding(BTS), which is being used in domestic construction sites, there are no related codes to the overall capacity of the BTS in the industrial safety and health act but only the ones which describe the testing method and the capacity of the each member of BTS. So we need to know the full capacity of the BTS at the time of the being used stage, not the ones of the members but the one cf the total BTS frame. In this study, first, the vertical frame member which is the basic element of the BTS frame, is tested for its capacity Second, the load test about the full strength of the BTS system are performed in two ways namely, for the first-story and the second-story BTS frame. In each case, the centric load(1/2 L) test and the eccentric load(1/4 L,0 L) tests are carried out, where L is the longer length of the BTS frame. According to the results of the experiments, first, the load endurance capacity of the first-story BTS frame are larger than the one of the second-story BTS frame at the same conditions. Second, the centric load endurance capacity is bigger than the one of the eccentric loading in the same story BTS system structure.

韓國語의 鼻音化에 있어서 規則順 매김과 英語誤諺音

Koreans mispronounce English words by the misapplication of Korean Phonological Rules to English words. Among the mispronunciations of them those by the misapplication of Korean Nasalization Rule is typical. The present study attempts to clarify the rule ordering of Korean Nasalization Rule through analysis and interpretation of the phenomena shown in the mispronunciation of English words. Many Korean Phonologists like Hur, C. W. Kim, Kim Renaud argue that n-lateralization Rule: n→1% 1 is phonitic and natural and obligatory, while/??/to [??] is sometimes made through analogy (which argumentation is slightly dealt by Hur.) In this study the efforts are made to prove that 1→n/n is no less natural than 1→n/??-. The naturalness and plausibility of Nasalization, 1→n/n- in Korean is studied, analyzed and interpreted from the view-point of, 1) Hyman's argumentation of 'ease of articulation': [+lat] after/n/is to be easily assimilated to [n] which had the same distinctive features [+ant], [+cor] that the preceding/n/has, just as after/m/or/??/, 2) Surface Phonetic Constraints by Shibatanni and other phonologists that in word initial or after consonant Sino-Korean/1/is changed to [n]: 1←n/??#-, and, 3) Stampe's argumentation of processes and rules in his Natural Phonology, Accordingly in 1-Nasalization Rule argued by many phonologists is 1→n/n-coucluded to be included, while so far they have only regarded 1→n/??#- as not occurring in case of C being n. Therefore, rule ordering of Korean Nasalization should be made: n-Lateralization 1-Nasalization(where SPC 1→n/n-should be added) Plosivization Stop Nasalization with both examples given in mispronunciations of English words and those in Korean. However, those examples in Korean should be words of free morphemes, but not of bound ones. In the end, comparison of English words with i-Epenthesis in English words makes a serous suggestion that the latter lets Koreans commit fewer errors in pronunciation of English words as shown in 'hopeless' : 3 errors by 3 factors p→m, 1→n, i-Epentiesis in/houpilisi/to [houmnisi] vs. 2 by only one factor i-Epenthesis in/houplis/to [houpillsi].

염화답실과 치환아닐린과의 친핵성 치환반응을 여러 용매계에서 진행시키고 이때의 반응속도 상수를 결정하였다. Br?nsted β값과 Hammett ρ?값들의 결과로부터 전이상태에서 결합파괴보다 결합형성이 우선함을 알 수 있었다. 분광용매화 상관관계식으로부터 용매의 수소결합주게(HBD) 산도 값(α)의 기여도 보다 용매의 편극-극성값(π?)의 기여도가 더 크게 작용함으로서 전이상태에서 결합 형성에 용매의 작용이 큼을 알았다. 또한 Dansyl과 Bansyl의 산 염화물보다 속도상수값이 크게 관측되어지는데 이것은 친핵체가 반응기질의 평면에 수직되게 공격함으로써 전이상태가 더욱 안정화되기 때문이며 이느 Marcus의 전이상태이론에서 concerted mechanism이 작용함을 의미한다 하겠다.

The purpose of this study was to develop the force transducer with load-cell to measure the forces acting on the pedal of bicycle. Three road racer who are national athletes were participated in this study. They were asked to run the bicycle at the speed of 38km/h and muscle moment of lower extremities was calculated with the variation of the saddle heights. The results obtained form the study were as follows; 1. The vertical force action on the pedal showed the maximum, 347N at the angle of 111(±3)˚ , and the higher the hight of saddle, the greater the vertical force. The anteroposterior force was 75.1N at the angle of 54.3(±2.8)˚ , Which was seen in H-1 condition. The rear fulling force was 27.8N at the angle of 211(±1)˚ , which was seen in H condition. 2. The maximum muscle moments of the ankle and knee joints were 46.5N and 31.6N in H-1 condition, where we could observe the peak vertical force acting on the pedal. 3. The muscle moment of the hip joint revealed the negative peak value -16.7N at the 91.7˚ (H condition), and the positive peak value at the angle of 248.7˚ (H-1 condition). 4. The force transducer to measure the forces acting on the pedal was approved its applicability for evaluating the muscle moment of the power legs with the variation of the saddle heights.

Individual genetic susceptibilities to cancers may result from several factors including differences in xeno-biotics metabolism to chemical carcinogens, DNA repair, altered oncogenes and suppressor genes, and environmental carcinogen exposures. Among them, genetic polymorphisms of metabolizing enzymes to chemical carcinogens have been recognized as a major important host factors in human cancers. They have two main types of enzymes: the· phase I cytochrome P-450 mediating enzymes (CYPs) and phase Ⅱ conjugating enzymes. The purpose of this study is to determine the frequencies of genotypes of phase I (CYP1A1 and CYP2E1) and phase Ⅱ (NAT2) metabolizing enzymes in healthy control and head and neck cancer patients of Korean and to identify the relative high risk genotypes of these metabolizing enzymes to head and neck cancer in Korean. The author has analyzed 132 head and neck cancer patients and 113 healthy controls using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) . The results were as following; 1.The frequencies of genotypes of CYP1A1, CYP2El and NAT2 in healthy control were as following; CYP1A1 exon 7 polymorphism; Ile / Ile: Ile/Val: Va1/Va1 = 59.3%: 36.3%: 4.4% CYP2El Pst I polymorphism, C1/Cl: C1/C2: C2/C2 = 61.1%: 32.1%: 6.2% NAT2 polymorphism; F/F: F/S: S/S = 43.4%: 48.7%: 8.0% 2.In analysis of phase I enzyme, Val/Val genotype in CYP1A1 exon 7 polymorphism and C2/C2 genotype in CYP2El Pst I polymorphism were associated with relative high risks to head and neck cancers (Odds' ratio: 2.09 and 1.37, respectively). 3.Among the genotypes of NAT2 enzyme polymorphism, S/S genotype of NAT2 enzyme had 1.03 times of relative risk to head and neck cancers. 4.In combined genotyping of CYP1A1, CYP2El, and NAT2 enzymes polymorphisms, the patients with Va1/Va1 and Cl/Cl, C2/C2 and fast acetylator, and Va1/Va1 and fast acetylator had higher relative risks than the patients with each baseline of combined genotypes (Odds' ratio: 2.82, 1.98 and 2.1, respectively) . These results suggest the combined genotypes of Va1/Va1 and Cl/Cl , C2/C2 and fast acetylator, and Val/Val and fast acetylator were more susceptible to head and neck cancers in Korean. And genotyping of metabolizing enzymes could be useful for predicting individual susceptibility to head and neck cancer.

Recently many dentists would like to select the implant installation for the restoration of partially or fully edentulous patient. Usually, it is needed at least 8mm of alveolar bone height for implant installation. But, in many cases, the implant installation is impossible due to anatomic limitation such as maxillary sinus, floor of nose, mandibular canal, lack of width, etc. So, dentists must come over these limitations by methods of sinus lift, nerve repositioning, transmandibular implant etc. Especially, a lot of ridges have inadequate bone height at the upper molar edentulous areas, and to insert implant for such sites represents low success rate. So, autogenous or allogenic or alloplastic bone can be grafted before or at the same thme with implant installation. We report a case of 22 year-old woman who was performed implant installation successfully by using sinus lift technique with iliac block bone graft to a patient whose low alveolar bone height made common implantation impossible. Now, she exerts good occlusive function at the time of 15 months after the operation.

Precise and detailed clinical research and evaluation based on objective standards are imperative factors in securing reliability of a clinical test. Built on this principle, this clinical test has been conducted during the period between March 1999 and March 2000 dealing with 31 outpatients treated with ShiHo-GuizhiTang or ShiHo-GuizhiTang modify and ShiHo-GuizhiTang mixed prescriptions at the Sung-bo ORIENTAL MEDICAL CLINIC. A variety of information relating to those patients has been collected and analyzed under such criteria as precise diagnoses and their clinical effectiveness. The analysis was duly based on "The theory of cold syndrome". Then, the 31 patients' individual clinical information was compared one another by breaking down the results into sub-categories including gender, age, disease, main symptom, blood pressure, pulse beats, syndrome of abdomen, treatment period, modify and mixed prescription, and evaluation. The result of this clinical test can be summarized as follows; First, ShiHo-GuizhiTang appears to be more frequently prescribed in the case of female patients than in the case of male patients despite the fact that it does not necessarily need to be applied only to female. In addition, the numbers of prescriptions of ShiHo-GuizhiTang in the two age groups consisting of elementary school children and economically active adults respectively were the highest among other age groups. Second, ShiHo--GuizhiTang proved to be most effective in treatment for respiratory ailments and arthritis. Third, ShiHo-GuizhiTang brought down blood pressure of hypertension patients and at the same time benefited patients with normal or lower-than-normal blood pressure who were vulnerable to diseases due to low disease-resistance. Fourth, ShiHo-GuizhiTang was effective in the case of frequent pulse(rapid pulse) and thereby indicating the fact it carries Taiyang superficies syndrome. 지맥 arises from suppressed immune responses owing to adrenocortical hormones. ShiHo-GuizhiTang controls and revitalizes those suppressed immune systems which stem from slow pulse and, as a consequence of that process, helps them return to normal condition of pulse. Fifth, from the standpoint of syndrome of abdomen, feeling of obstruction in the epigastrium serves as an important standard in the process of diagnosing diseases and evaluating effectiveness of treatments. Sixth, according to the results of the clinical test with the 31 patients, a total of 81 percent of test subjects benefited from the treatment. The figure is the sum of 52 percent of Ⅰ-class (both main symptom and accompanying symptoms had been eliminated) and 29 percent of Ⅱ-class (part of main symptom and accompanying symptoms had been eliminated) respectively. All told, it is safe to say that ShiHo-GuizhiTang can elect to be a viable clinical treatment. In conclusion, it is estimated that this clinical study has drawn up guidelines for objective diagnostic standards and evaluation on specific treatments' effectiveness. This will lead to more general application of ShiHo-GuizhiTang. On top of that, this study could also provide an opportunity to stress the significance of ShiHo-GuizhiTang and ShiHo-GuizhiTang modify and ShiHo-GuizhiTang mixed prescriptions as an alternative treatment for collagen disease which comes from environmental degradation and pollution.
