Experiments were carried out to study the effectiveness of METAP as a slow released fertilizer on the growth, grain yield and its components of paddy rice, and to compare its effects with those of single fertilizers in the fields of 3 Crop Experiment Stations and 7 provincial Offices of Rural Development. The effectiveness of METAP seems to be different according to the physical and chemical characteristics of soil, the time of application, climatic conditions, variety and cultural methods. Therefore, the experimental results obtained from the above experiment are summurized as follows: 1. When METAP was applied into sandy soil, grain yield was increased due to increase of the number of panicles, and split application of METAP was more effective than basal only. However, in the reclaimed soil, not heavily percolated soil and fertile soil, no differences were observed between MET AP and single fertilizer applied plot. 2. When a rice variety, 'TONGIL' which is sensitive to the low temperature and produce higher yield in the early transplanting, was not transplanted early and air temperature is relatively lower during the ripening stage, the percentage of ripened grains and 1,000 grains weight were not higher in the METAP applied plots than in the single fertilizer applied plots.

To analyze the genetic relationships among 23 accessions of Asparagus cochinensis $L_{OUR}$, random amplified polymorphic DNA(RAPD) analysis was performed using artificially synthesized 10 primers. The range of polymorphism was $42.9{\sim}91.7%$ with an average of 72.9% in 85 randomly and specifically amplified DNA fragments. On the. basis of similarity coefficient analysis by unweighed pairgroup method, arithmetic average method(UPGMA), 23 accessions of Asparagus cochinensis $L_{OUR}$ could be classified into 6 groups at the similarity coefficient value of 0.82. Group I contained 5 accessions, Group II contained 6 accessions, Group III contained 6 accessions, GroupIV contained 2 accessions, Group V contained 2 accessions and Group VI contained 2 accessions. The range of total genetic similarity coefficient value of 23 accessions of Asparagus cochinchinensis $L_{OUR}$ was $0.47{\sim}0.92$ and average value was 0.76. To obtain more exact data from PCR, we also tried to develope enhanced RAPD techniques using Bovine Lacto Transfer Technique Optimizer(BLOTTO). In RAPD analysis of Asparagus cochinensis $L_{OUR}$, we could obtain better RAPD results by adding BLOTTO at a final concentration of 1%.

The purpose of this study was to evaluate the attitude and knowledge level of a group of elementary school teachers in management of traumatic dental injury. The sample consisted of 231 elementary school teachers in Jeon-Buk province, and data was collected by means of a self-administered questionnaire. The questionnaire surveyed the teachers'general information, attitude on the dental trauma education, knowledge of management of tooth fracture, luxation, avulsion and tooth storage media. Only 15.2% of the teachers had received dental first aid treatment education, but 97% were favorable to receiving education. Although there were differences among the questions, insufficient knowledge and awareness of the management of traumatic dental injury were shown in the majority of teachers. It is recommended that education strategies and programs for improving the awareness of immediate management of traumatic dental injuries are necessary for elementary school teachers in Jeon-Buk province.

We performed field investigations at six stations in Buk Stream of Goseong-gun, Gangwon-do, Korea, from May to September 2009 to understand the stream's fish fauna and community structure. In the survey, 31 species belonging to 20 families were collected. Dominant species by number was Zacoo koreanus (30.0%), and subdominant species were Pungitius kaibarae (9.4%) and Rhynchocypris steindachneri (9.3%). In biomass, the dominant species was Tribolodon hakonensis (35.5%), and subdominant species were Z. koreanus (22.5%) and Cobitis pacifica (7.5%). Eight Korean endemic fish species and two endangered species (P. kaibarae and Pungitius sinensis) were collected. In addition, four anadromous fish species (T. hakonensis, Oncorhynchus masou masou, O. keta, Gasterosteus aculeatus) and two amphidromus fish species (Plecoglossus altivelis altivelis and Gymnogobius urotaenia) were observed. Interestingly, we verified the existence of several fish species in Buk Stream where they have not lived before. Those species were previously reported to live only in rivers that run into the western and southern sea of Korea. Five of those species (Zacoo koreanus, Z. platypus, Silurus microdorsalis, Liobagrus andersoni and Coreoperca herzi) were reported in Buk Stream in the 1980s. The other species (Pungtungia herzi, Pseudorasbora parva, Squalidus multimaculatus, Misgurnus mizolepis, Koreocobitis rotundicaudata, Silurus asotus and Odontobutis interrupta) have been introduced since the 1990s.

To investigate the relationship between craniofacial growth and bone maturity of the hand wrist in normal occlusion, the author took cephalogram and handwrist radiogram of 391 students (male 192, female 199) and assessed the measurements of cephalogram according to skeletal maturity stages of the hand and wrist. In this study, four skeketal stages and 36 linear, angular measurements of the cephalometrics were selected. In hand-wrist X-ray the bones used to determine skeletal maturity were the middle phalanges of the third finger, and distal epiphysis of the radius. In cephalogram, the landmark used to measure the angle and length were N, S, Po., Ar., Go., Me., Gn., Pog., Point B, Point A, ANS, PNS, Or., U1, L1, U6, L6 etc.. The results were as follows, 1. The table of mean, standard deviation, p-value from measurements were made in each group and both sex. 2. The increased measurements according to skeletal maturity were anterior cranial bese length, posterior cranial base length, ramus height, anterior facial height, posterior facial height, L1 to mandibular plane (mm), facial plane angle. In contrast to, decreased measurements were genial angle, facial cnvexity and facial plane angle. 3. Denture pattern measurements (IMPA, FMIA, occlusal plane to Go-Gn, interincisal angle, U1 to SN plane, U1 to SN plane, U1 to facial plane, L1 to facial plane etc.) .had nothing to do with skeletal maturity. 4. Skeletal maturity had close relationship with craniofacial growth, but had little to do with tooth development.
