Starting from the stoichiometric composition of $K_2$CO$_3$: Li$_2$CO$_3$: Nb$_2$O$_5$=3 : 2 : 5 with the mole ratio, $K_3$LiNb$_6$O$_17$ 17/ single crystals were grown using the Czochralski method. Although the starting melt composition corresponds to the $K_3$Li$_2$Nb$_5$O$_15$ crystals, the chemical composition of the as grown crystals appears to be $K_2.95$Li$_1.33$Nb$_6.17$O$_17$ or $K_2.60$Li$_1.17$Nb$_{5.44}$ 5.44/O$_{15}$ which relatively contain fewer Li ions than $K_3$Li$_2$Nb$_5$O$_15$ crystals. We investigated the influence of the deficiency of the Li ions in the tetragonal tungsten bronze structure through the measurements of DE loop, temperature dependent dielectric constant, differential thermal analysis and temperature dependent X-ray diffraction pattern.

Dry matter production, leaf area growth and total nitrogen changes were studied in Glycine max. soybean communities, which were grown in sandy loam soils controlled to provide various moisture levels, i.e., 5-7%(level 1), 8-10%(level 2), 11-13%(level 3), 14-15%(lev디 4), 17-20%(level 5) and 22-24%(level 6). A summary of the results is shown. The maximum dry matter production of leaves, stems and nodules and the maximum leaf area per unit area were at level 5, but the maximum of root dry matter production was at level 4. Total nitrogen content of the soybean plant decreased with growth, but each level of soil moisture content also showed a little difference. Water content of the plant decreased with plant age and soil water deficiency, especially in roots and nodules. Nodule formation increased in proportion to soil moisture content. total nitrogen content of the soil on which the soybeans grew, increased from 0.23% before sowing to 0.30% at 100 days after sowing. It seems that soil water content acts as a linear factor in the elongation or dry weight increase of shoots and roots until increasing to level 5. Considering the pattern of plant growth through analysis of the shoot and root dry weight ratio, or the photosynthetic organ and non-photosynthetic organ dry weight ratio, the asymptote of plant growth at a high soil water content exceeded that at a low soil water content.

Orthodontic treatment planning of cleft lip and palate requires consideration of the characteristic features, growth pattern and functional disorders related to cleft lip and palate patients. Tissue deficiencies and constriction of the scar tissue in surgically treated cleft lip and palate results in disturbance of maxillary growth and deficiency of midfacial region with anterior and posterior crossbite. These patients often present congenital missing of teeth, supernumerary teeth, malformed teeth, or ectopic position of teeth, which should be treated by orthodontic treatment by expanding upper arch followed by fixed appliance. Proper use of retainer and continuous follow-up is needed to prevent relapse after orthodontic treatment has finished. Also we have to pay attention to correct speech disorder which is caused by the velopharyngeal insufficiency.

We used enzyme electrophoresis to evaluate genetic diversity in five populations of endemic ash, Fraxinus chiisanensis in Korea. Of 15 putative allozyme loci examined 26.7% were polymorphic and expected heterozygosity for the species was low (0.082). Within the range, population were highly differentiated ($F_{ST}$=0.356) and little genetic variation was explained by geography. The pattern of distribution of variation showed low genetic variation within populations and pronounced divergence among populations, which was consistent with the prediction for the effects of limited gene flow and local genetic erosion. Although the frequencies of male plants were dominant ranging from 79.3% to 89.4%, most mating events seems to be inevitable mating between relatives in small populations based on heterozygote deficiency of this species. Small effective population size and the limited dispersal contributed to the low rates of gene flow within as well as between populations.

The popularity of clear overlay retainers (CORs) has increased recently because of their advantages such as better esthetics, cost effectiveness, easy fabrication, and good compliance. However, a deficiency in posterior occlusal settling is a reported limitation of CORs. The aim of this study was to evaluate the posterior occlusal contact changes in a new type of clear orthodontic retainer called Oral-treaper (OTP), which consists of three layers and has stronger mechanical characteristics than do conventional retainers. Three patients who completed fixed orthodontic treatment received OTP as a removable retainer. Cast models were fabricated after the removal of fixed appliances (T1) and after 4 to 11 months of using the retainers (T2). We evaluated all the cast models to compare the post-orthodontic settling pattern during the use of the OTPs. The depth of occlusal contacts was evaluated using color maps. The OTP did not prevent vertical settling in all patients but resulted in an improvement in posterior occlusal contact points.

Comparing to the conventional power systems, PV(photovoltaic) outdoor lighting system applications are evaluated as the most economical application. In this paper, we installed two PV lighting systems, which uses LPS(low pressure sodium) and electrodeless lame as their loads, and applied a computer-based data acquisition system using the Labview program for monitering purpose and effective operations, considering battery life time Also, we observed the generated power from the solar array, and energy losses comparing to its installed capacity. Because most PV system performance procedures have looked at the performance of the individual components and have deficiency of addressing how the integrated system works, we confirmed the decrease possibility of the solar amy capacity after analyzing the performance of the installed PV lighting systems.

Objectives: The purpose of this study was to report the effect of Korean medicine (KM) treatment on a patient diagnosed with cluster headache. Methods: The patient included in this study was diagnosed with cluster headache who received KM therapy (herbal medicine, acupuncture, moxibustion, cupping, and chu-na treatment). The main symptom of the patient was pain in the left occipital region and orbital region. It was diagnosed as a pattern of liver depression and spleen deficiency by oriental medicine. During the hospitalization period, treatment effect was evaluated by NRS. HIT-6. BDI, and STAI were additionally performed to assess depression and anxiety. Results: After 24 days of treatment, the intensity of headache decreased from NRS7 to NRS3. During follow-up at two weeks, there was no pain. Normal daily activities were possible. Conclusions: Korean medical approach might be useful for pain relief and restoration of daily living ability for patients with cluster headache.

Objectives : In this study, we aimed to analyze the latest knowledge of pityriasis rosea(PR) through oriental-western medical review on PR. Methods : We searched Pubmed, CNKI, and OASIS to select papers related to the cause, mechanism, diagnosis, classification, treatment, and herbal treatment of PR. Results : The results are as follows. 1. Although the exact cause of PR is not known, it has recently been found that reactivation of latent human herpesvirus-6 and human herpesvirus-7 infection is a possible etiology. Most patients require emollients, antihistamines, topical steroids, and macrolides. Acyclovir, and narrow-band UVB therapy are also used. 2. The cause and mechanism of PR in Chinese and Korean medicine can be mainly summarized as wind-heat, blood heat, and blood deficiency and wind-dryness. Most of the herbal medicine used have the effects of clearing heat, cooling the blood, detoxifying, dispelling wind, relieving itching, nourishing blood, and moistening dryness. Conclusions : In Chinese and Korean medicine, it is necessary to organize the representative prescriptions according to pattern identification, and it is also necessary to study the atypical types of PR and its treatment methods. It is thought that research on oriental and western combination therapy should be continuously conducted, and efforts to develop Korean medicine formulations are needed to revitalize clinical research in Korea.

Objectives: This study was performed to review the research trends in the treatment of anorexia nervosa (AN) in Traditional Chinese Medicine (TCM). Methods: Studies were searched through The China National Knowledge Infrastructure (CNKI) database. The search term for the subject were 'Eating Disorder', and 'Anorexia Nervosa'. Clinical research that conducted TCM treatment for AN patients were included. Studies were analyze according to study design, therapy method, diagnostic criteria, population and intervention. Results: 23 articles were selected. According to study design, studies were classified into two randomized controlled trial (RCT), three single group before-and-after studies, and 18 case reports. According to therapy method, they included 19 herbal medicine studies, two acupuncture treatment studies, and two complex treatment studies. The most common pattern identification was 'liver depression with spleen deficiency' (肝鬱脾虛), and the most used herb was 'Root of Bupleurum falcatum' (柴胡). Most of the studies showed effective results in increasing appetite and weight. Conclusions: The results of our study demonstrate that TCM treatments for AN has been effective in alleviating chief symptoms. However, in terms of evidence-based medicine, lack of RCT on TCM treatments for AN and absence of objective diagnostic criteria in case reports are limitations. Therefore well-designed further clinical studies should be performed based on the results of this study are recommended.
