Diastema is thought to be a problem related to aesthetics, pronunciation, or malocclusion. Due to its extent and patient conditions, orthodontic treatment, prosthodontic treatment, and conservative direct resin restoration are the treatment options for diastema closure. Additional factors need to be considered when deciding on the most appropriate treatment of diastema, particularly for patients with cerebral palsy. A 13-year-old girl visited the Department of Pediatric Dentistry at Yonsei University Dental Hospital with a chief complaint of the large gap between her upper front teeth. After clinical and radiographic examinations, midline diastema of 4.5 mm, protrusive maxilla incisors, congenital missing teeth, retained primary teeth, etc. were identified. Prosthodontic treatment with intentional root canal treatment was not appropriate because of the patient's age. Dental spaces can be closed effectively via orthodontic appliances. However, additional prosthodontic and restorative intervention is unavoidable, which incurs significant costs and requires more time. Instead of orthodontic and prosthodontic treatment, direct resin restoration can address the chief complaint; these restorations are reversible, less harmful to other oral structure and teeth, relatively easy to apply, less expensive than other treatments, and require shorter office visits. Midline diastema can be treated in several ways. For diastema closure in patients with cerebral palsy, conservative resin restorations are a short, simple, and appropriate treatment compared with orthodontic or prosthodontic treatments.

Talon cusp is cusp-like structure that develops additionally in crown of anterior tooth. And it is one of dental anomalies. Talon cusp can cause various diagnostic, functional, aesthetic problems depending on the size and configuration of cusp. there is a tendency for caries to occur in the developmental grooves, and advanced attrition, periodontal problems, irritation the tongue and temporomandibular pain, occlusal interference and displacement of affected tooth may result. Therefore, early diagnosis and appropriate treatment of each case is important so that it minimize local problems, such as caries, periodontal diseases, and malocclusion. These cases which are in permanent and primary anterior teeth are about gradual reduction forming reparative dentine and complete reduction of talon cusp and root canal therapy which is an alternative and effective form of treatment when gradual reduction of talon cusp may not be possible.

Supernumerary tooth describes an excess of tooth number, which are found in primary dentition with 0.3-0.8%, permanent dentition with 1.0-3.5% prevalence. Their frequency is about 2:1 (male vs female) and 9:1 (maxilla vs mandible). However, occurrence is very rare in the incisor region of the mandible. We need a early diagnosis and appropriate treatment plan because of possibility of diastema, eruption failure, displacement, rotation of the associated permanent teeth, root resorption, dentigerous cyst with presence of the supernumerary teeth. This is a case report about two impacted supernumerary teeth found in madibular anterior region of 6 years old girl. One was extracted and another was retained because of fusion with permanent central incisor on the labial surface.

SrA1$_2$O$_4$was prepared by polymerized complex method and crystalline growth was investigated. Precursors was annealed at temperatures form 900 to 100$0^{\circ}C$, for different time(between 0 and 10 h), and that was determined by Transmittance Electron Microscopy (TEM) and X-Ray Diffractometer (XRD). Crystalline size was calculated by Scherrer's equation and its variation was studied. It increased rapidly in the primary stage and then slowly as a function of square root of time. so, It was grown to 32, 45 and 59nm after heating treatment at 900, 980, and 100$0^{\circ}C$ for 10 h respectively. Cstalline growth rates were 4.5, 9.6, and 18.6 nm/h$^{1}$2/ as a addition of heating temperature.

Containerized Quercus acutissima seedlings were inoculated with vegetative mycelial inoculum of Pisolithus tinctorius and were grown in a green-house. The ectomycorrhizal fungus, P. tinctorius (Pt) increased growth of the container-grown oak seedlings. Of three treatments, Pt inoculation stimulated remarkably primary lateral roots, shoot growth, and root collar diameter and leaf area development, compared with either non-inoculated or natural soil treatment. In addition, Pt-inoculated seedlings produced ectomycorrhizae, by 71.1 percent. However, noninoculated and naturally grown seedlings were free of natural ectomycorrhizal. Ectomycorthizal roots developed more abundantly in the middle portion of the container than in the top or bottom portions.

Background: Several Korean medical doctors have been practicing applied kinesiology (AK), invented in 1964 by Dr. George J Goodheart, USA. Although the efficacy of traditional acupuncture (TA) and pharmacopucture treatment for lumbar conditions/diseases has been examined, the possible benefits of combining TA and AK have not been reported. Therefore, the aim of this study was to report the effects of combining TA and AK treatment for lumbar disorders using the Japanese Orthopedic Association lumbar score (JOALS) assessment. Methods: There were 21 outpatients treated at Samse Korean Traditional Hospital between March 2018 and September 2018, who presented with L4/L5 or L5/S1 root radiculopathy associated with lumbar spinal stenosis (LSS) and lumbar herniation of intervertebral disk (LHID). They were treated 10×(2 sessions per week, for 5 weeks) with TA and AK approaches that included a category block, manipulation or strain/counterstrain treatments. The primary outcome was mainly assessed using the JOALS score which was used before (0 ×), during (5 ×), and after treatment (10 ×). Results: There were 19 patients diagnosed with LSS and 2 were diagnosed with LHID. Using the JOALS assessment, TA and AK combined approaches improved the lumbar conditions of all 21 patients after 5 × treatmentsand continued to improve after 10 × treatments (p < 0.001). Conclusion: Combined TA and AK treatment was effective in treating spinal conditions/diseases. Prospective, relevant, well-controlled protocols for TA and AK therapies for various conditions are needed.

Post-herpetic neuralgia(PHN) is a chronic pain syndrome associated with the reactivation of a primary infection with varicella zoster virus(chinken pox), which leads to a chronic infection of dorsal root ganglia. The most common risk factor for shingles and its potential sequela, PHN, is advanced age. For a significant number of patients, the pain following healing of shingles can persist for months to years. If this pain, classified as PHN, persists longer than one month. PHN often leads to depression, disrupted sleep, decreased productivity, and utilization of health care. We treated a 60 year-old female patient who suffered pain and headache after Stellate Ganglion Blocks(SGB). In identifying points for differentiation of syndrom(辨證), this subject was diagnosed as Yangmyeong Merdian wind-heat syndrom(陽明經風熱證) and was administered Seungmagalgeuntanggamibang(revised Shengmagalgen-tang, 升麻葛根湯加味方). To ease pain, Western medication was administered as well. After fourteen days of treatment, pain and other symptoms improved.

Protocol was established for production of virus free healthy seeds using meristem ($0.3-0.5\;\cal{mm}$ in size) culture and field management under net house condition in tomato. The isolated meristem was found well established in MS liquid medium containing $0.1\;\cal{mg}\;1^{-1}\;of\;GA_3$. For shoot and root development either from primary meristem or from nodal segment of meristem derived plants, semisolid MS medium having $0.5\;\cal{mg}\;1^{-1}$ of IBA was found most effective. The elimination of the studied viruses (ToMV, CMV, ToLCV) in meristem-derived plants was confirmed by DAS-ELISA test. For field management of the virus eradicated meristem-derived plants, use of net house was found very effective measures to check viral vector visit and eventually infection. The meristem-derived plants were vigor and high yielder than the native seed derived plants and produced healthy seeds. Due to stop vector visit, no viral symptoms were observed in both $R_1\;and\;R_2$ plants cultivated in net house condition. Starting of viral infestation was observed in $R_2$ generation when they were planted in open house condition without control of vector visit. Therefore, for management of viral diseases, use of virus free meristem derived plantlets and their subsequent cultivation in soil under net house condition without using any vector killing insecticide can be recommended for producing healthy seeds in tomato. The developed protocol for environmentally healthy tomato seed production in Bangladesh may be used in the countries having similar tropical like environment conducive for viral vector visit.

In our country there are five species of Morus genus including Morus alba L.. Also their varieties and hybrids are distributed so much. In sucession of previous report we collected control and marketing specimens of Mori Cortex Radicis, comparative experiments were pharmacognostically carried out to identify the control specimen by the differences of external and internal morphology. It was difficult to identify marketing specimens by external morphology, because they are similar in spite of conparating with control specimen which the origin is definite. In internal morphology, medullary ray is developed near the cambium to primary bark in control specimen A(Morus alba series) and C(M. Lhou series), but less developed in B(M. bombycis series). The difference of these three series was observed. The thickness of cork layer is almost the same($7{\sim}12$ layers) in A and C series, but B is thin layer and sample E(that on the market) is generally more thick and has a stick cork cell. The kinds of starch, Ca-oxalate and latex, cell centents were same, but it was easy to identify them by the differences of their distribution. The bast fibre of D(wild specimen) and E were light lignified, latex tube of A and C series was richer distributed than others. These results show that the origin of Mori Cortex Radicis on the market can be appreciated in four groups of Korean Morus genus which are M. alba, M. bambycis, M. Lhou series and the others.

The present study was designed to observe whether nutritional education on children or mothers of the children who avoid to eat vegetables can improve the preferences for the vegetables of the subjects. The subjects were 45 children who are fourth to sixth grade of primary school in Bibong. They were assigned to one of three groups which are Control, Children Education and Mothers Education groups. Control group was not given any special education, while experimental groups were given nutritional education for 4 weeks. The effects of education was evaluated in the aspects of preference changes for vegetables, nutritional knowledge, attitude and food behavior of the subjects The results are summarized as follows. 1. Preferences to cucumber, lettuce, chinese cabbage and raddish were high in three groups while greenonion, onion, lotus roots and red pepper didn't suit for their taste. 2. Significantly increased scores for the preference to red pepper, pumpkin, Dorajee(root of chinese bell-flower), braken, mushroom was shown only in the children who had nutritional education while the children in the group of Mothers Education improved their preference only cabbage and lotus roots. 3. Nutritional knowledge of the children in Children Education group has improved significantly(p<0.05). While there was no significant difference between control and Mothers Education group. 4. When scores for food habit of mother and children were estimated, there was no significant difference among three groups. However, score of food habit in children was higher than that of mothers. 5. Food habit and nutrition knowledge of mother were not well corelated with dietary attitude and behavior of their children. These results indicate that the program of nutrition education in the present study can improve the food choice of children for vegetable and correct one-sided food habit. The program applied in this study would serve a kind of model for the dietetic teachers to guide the children who mainly dislikes vegetables.
