The removal efficiency of Cu and Fe contaminants on the silicon wafer surface was examined to investigate the effect of cleaning solutions on the behavior of metallic impurities. Silicon wafers were intentionally contaminated with Cu and Fe solutions by spin coating and cleaned in different types of cleaning solutions based on $NH_4OH/H_2O_2/H_2O\;(SC1),\;H_2O_2/HCl/H_2O$ (SC2), and/or HCl/$H_2O$ (m-SC2) mixtures. The concentration of metallic contaminants on the silicon wafer surface before and after cleaning was analyzed by vapor phase decomposition/inductively coupled plasma-mass spectrometry (VPD/ICP-MS). Cu ions were effectively removed both in alkali (SC1) and in acid (SC2) based solutions. When $H_2O_2$ was not added to SC2 solution like m-SC2, the removal efficiency of Cu impurities was decreased drastically. The efficiency of Cu ions in SC1 was not changed by increasing cleaning temperature. Fe ions were soluble only in acid solution like SC2 or m-SC2 solution. The removal efficiencies of Fe ions in acid solutions were enhanced by increasing cleaning temperature. It is found that the behavior of metallic contaminants as Cu and Fe from silicon surfaces in cleaning solutions could be explained in terms of Pourbaix diagram.

This study was carried out among 34 patients who visited Yonsei Dental Hospital from 1996. 1. to 1999. 5 for trigeminal neuralgia. By studying the patient's treatment prior to visiting our hospital, features of trigeminal neuralgia, treatment process of trigeminal neuralgia, prognosis of treatment, consultation with other professions and involvement of surgery, etc., the results are as follows: 1. 67.7% of onset age range from 40s to 60s, and average age is 50.2. 2. Ratio of right to left involvement is 1:2.1, male to female ratio is 1:1.9. 3. Occurrence rate of each branch is V3(44.1%), V2(11.8%), V1+V2+V3(11.8), V1+V2(8.8%). 4. Treatments prior to admission to our hospital are extraction(5.9%), endodontic treatment(5.9%), medication(11.8%), Oriental Medicine treatment(5.9%). 5. Routes of admittance to our hospital are by their preference(55.9%), local clinic referral(32.4%), E.N.T referral(5.9%), Neurology referral(5.9%). 6. 70.6% of patients treated at our hospital who were relieved of symptoms, were referred to Neurology(66.7%) and Pain Clinic(33.3%) for the reason of relapse, side effects of the drug itself, incomplete relief of pain. 7. 2 patients who were referred to medical part showed brain vessels contacting trigeminal nerve root on Brain MRangiography. But pain is being controlled by medication and no specific surgical procedure was carried out. The results show that 17.7% of patients admitted received inappropriate early treatment. In order to relieve tooth loss and patient's psychologic stress due to inappropriate treatment, precise differential diagnosis must be made among local teeth disease and idiopathic facial pain. Medication may show side effects of the drug itself, incomplete relief of pain or relapse of symptoms. Therefore, to treat trigeminal neuralgia appropriately by drug injection, surgery or radiation therapy, consultations among dentists, neurologists and anesthesiologists are required.

The purpose of this study is to evaluate the relationship of menstrual cycle and halitosis by measuring the concentrations of Voltile Sulfur Compounds, secretion rate of unstimulated saliva, secretion rate of stimulated saliva and viscosity of saliva during the menstrual cycle. The subjects were 19 female dental students of Yonsei University who had relatively good alignment of the teeth. They hadn't taken antibiotics or oral contraceptive pills during the few months prior to the experiment, and they didn't have any dental caries involving the pulp or periodontal disease. Lady-$Q^{(R)}$(Alpain Korea, Korea), which confirms the ovulation using saliva, was used to find out the menstrual cycle of subjects. Their history was taken and their basal body temperature was measured. On the basis of these data, the amount of Volatile Sulfur Compounds, secretion rate of unstimulated saliva, secretion rate of stimulated saliva, viscosity of saliva were measured during 1 day of the proliferative phase, 3 days of ovulatory phase and 1 day of the luteal phase within the menstrual cycle. The results were as follows : 1. The amount of Volatile Sulfur Compounds, secretion rate of unstimulated saliva, secretion rate of stimulated saliva, and viscosity of saliva showed no statistically significant cyclic change during proliferative phase, ovulatory phase, and luteal phase(p<0.05). 2. Between the secretion rate of unstimulated saliva and secretion rate of stimulated saliva, there was significant correlation during proliferative phase and luteal phase(p<0.05) and there was no significant correlation during ovulatory phase but relatively close result was seen. 3. The amount of Volatile Sulfur Compounds during proliferative phase and luteal phase had statistically significant correlation(p<0.05). 4. Secretion rate of stimulated saliva during proliferative phase and ovulatory phase, proliferative phase and luteal phase, ovulatory phase and luteal phase had significant correlations (p<0.01).

In two female siblings, growth and developmental retardation, poor sucking, anorexia, floppiness and respiratory difficulty developed around 2 and 4 monthes of age in each, and the respiratory symptoms rapidly aggravated to comatose states and finally into death one month later, On admission at emergency room, severe acidosis and high lactate and pyruvate levels in serum and cerebrospinal fluid were revealed in one. Brain computed tomography and magnetic resonance imaging revealed identical bilateral involvement of putamen in both of the sibs, which made the diagnosis of Leigh disease(subacute necrotizing encephalomyelopathy) possible. There is also a family history of early death in infancy period: an elder sister and a brother of mother died with unknown cause at their 5 and 10 months of age. Mitochondrial enzyme functions could not be assayed.

The detached housing areas in Korea were developed by the Land Readjustment Project initiated by the Korean government during the 1960s and 70s. However, in recent years, the sites for multi-family housing, town houses, or high-rise apartment complexes are being developed disorderly according to the principles of economy and investment. Additionally, due to the legal regulations, such as the required maximization of building coverage ratio and the required open land ratio within a housing site, owning a garden by each household, which is the biggest advantage of detached homes, is no longer possible, and as a result, open space is becoming insufficient. Such trends tend to damage the urban landscape, and decrease the efficiency of development. Accordingly, as an alternative solution for the diversified urban housing and the improved environment, the development of large-scale complexes or each lot should be promoted, and at the same time, a composite type of housing, which is derived from the advantages of detached homes and multi-unit housing, and which is applicable to real situations, should be developed. The current trend of urban housing development is predominantly toward a clustered housing type, but related research is still at an early stage. Thus, this study is conducted to suggest an improvement measures for the residential environment within the detached housing sites by analyzing the types of composite housing, which have both the advantages of detached housing (e.g., pleasant residential environment including the characteristics of ground base, individualized usage of exterior space, uniqueness, independence, high habitability, flexible use of space) and the advantages of contemporary clustered housing (e.g., convenience, security, economic efficiency, community-like characteristic).

The purpose of this study is to understand the reason why the learners of Japanese language are having difficulties in properly using final particles “ね” and “よ” and help instructors teach learners their appropriate usage. This research carried out an analysis of the presentation of “ね” and “よ”, two of the most frequently used final particles in spoken Japanese, in several Japanese language textbooks used in universities. This study begins with considering the usage of “ね” and “よ” by analyzing their presentation in spoken Japanese. As a result, the analysis revealed that the particles was properly used in the textbooks in terms of 'the amount of learning' and 'learning by level'. However, The portion of learning “ね” was excessively biased and the examples were presented without explaining the detail usage of “ね” and “よ” in the textbooks. It could give difficulties to teachers to guide the balanced use of the particles in spoken Japanese and create confusion for learners. Further studies on this topic must include an analysis of instructional guide lines for teachers, which were not included in this study. Such research expansion will help upgrade Japanese textbooks used in universities.
