  • The purpose of this study is to find a way to improve damaged forest in rural area in terms of both landscape . quality and regulation. Mountain and forest cover 65% of total land in Korea, and the shortage of areas for developing housing, road and facilities made us to use forest area for above purposes. This led various types of damages on the sensitive rural landscape visually and ecologically. There are rules and regulations for decreasing damaging effect by constructions on forest area, but it was not so effective because theses rules focused on quantitative issues only. This study will consist of three phases, 1. analyse landscape damage types by development tendencies in forest area 2. find diminution plan on each damage types 3. set improvement on rules and regulations both qualitatively and quantitatively. This study will meet the goal of improving and managing rural and forest landscape by providing objective standards, rational procedure and amelioration plan.

  • A novel method for optical phase shaped binary transmission (PSBT) generation has been recently reported and experimentally evaluated. An amelioration of the optical signal-to-noise ratio (OSNR) sensitivity of the optical PSBT modulation format is proposed with the application of the concepts of enhanced electrical PSBT signal generation. Enhanced optical PSBT is proposed here as a modulation format producing a 0.7 dB gain in OSNR sensitivity compared to OPSBT, while maintaining a good robustness to group velocity dispersion: 100 ps/nm for enhanced optical PSBT and 120 ps/nm for optical PSBT, compared to 50 ps/nm for standard NRZ signals.

  • The purpose of this study is to suggest the fundamental data of durability which effects on the Carbonation of concrete by adding various admixture additives. Thus, We have experimented the accelerated test on the concrete blending which was admixed by blast furnace slag, fly-ash, silica fume , durability amelioration and it was cured 7weeks after twenty eight days water curing. The result of this experiment is that Carbonation speed increased extremely when water cement ratio went up, and by growing of replace cement ratio of admixture additives. The specimen which was added fly-ash, blast furnace slag, silica fume has the faster Carbonation speed than the specimen which was not added admixture additives. All of these specimen, fly-ash has the fastest progress speed.

  • Purpose: To investigate whether there are significant changes in regional brain metabolism in patients with Parkinson's disease after thalamotomy using proton magnetic resonance spectroscopy (1H MRS). Materials and methods: Fifteen patients with Parkinson's disease of mean age 56.5 years (7 males and 8 females; mean age, 56.5 years) that have treated with levodopa were included. All patients with tremor experienced amelioration of their symptoms on the side contralateral to the thalamotomy. As a single-voxel technique, 1H MR spectra were obtained from the volume of interested regions in thalamus and primary motor cortex. Spectral parameters were: 20 ms TE, 2000 ms TR, 128 averages, 2500 Hz spectral width, and 2048 data points.

  • The nutritional significance of essential amino acids, as well as non-essential amino acids, is well documented in poultry production with regards to growth performance and protein accretion. However, the function of amino acids in the stress response is still unclear. L-Pipecolic acid, a L-lysine metabolite in the brain, induced a hypnotic and sedative effect acting via the ${\gamma}$- aminobutyric acid receptors. L-Arginine also induced a sedative effect via its metabolism to L-ornithine. In addition, three-carbon nonessential amino acids like L-alanine, L-serine and L-cysteine also induced sedative effects. These facts suggest that the requirement for amino acids in both essential and non-essential types may require reconsideration to add the concept of stress amelioration in the future.

The Effect of Deer Horn on the Liver and other Organs of Cholesterol Administered Rabbits (녹용(鹿茸)이 Cholesterol 투여가토(投與家兎)의 간조직(肝組織) 및 각장기(各臟器)에 미치는 영향(影響)(제 5 편)(第 5 編))

  • The oral admistration of deer horn extract was proved to cause a considerable amelioration to the impairment of hepatic oxidative phosphorylation and to the decrease of ATP content in liver tissue induced by cholesterol ingestion. Deer horn extract was shown to accelerate considerably incorporation of $acetate-1-C^{14}$ into cholesterol in liver tissue and it tends to restore a decrease of GOT activity of liver tissue, caused by cholesterol administration. Histological examination showed that deer horn extract had a remakable preventive effect aginst fatty infiltration of organgs such as liver, heart, spleen, and adrenal gland of cholesterol given rabbits.

  • This paper aims to develop the learning contents of PBL based program and analyze the result of evaluation questionnaire to examine the students' thoughts concerning the effectiveness of PBL course and their satisfaction. 'Discussion' is one of the representative communicative types, especially requesting both communication competence and teamwork among team members. This study was conducted with 218 junior and senior students taking lectures of ${\ll}$Presentation and Debate Skills${\gg}$ in the college of engineering at Pusan National University. According to the evaluation result, students experienced various effects of PBL such as (1) self-directed learning, (2) cooperative learning, (3) problem solving skills, etc. Students pointed out also as merits of PBL course, (1) knowledge acquisition and information sharing among students, (2) improvement of communicative competence, (3) amelioration of teamwork, (4) progress of the problem solving skills. However, there have been several difficulties and problems during PBL process, implications for ameliorating PBL based were discussed and suggested in detail.

  • The authors address the problem of ameliorating or updating existing educational buildings. This building typology is quite sensitive to social and media pressure, mainly when accidents have occurred nearby. When a building is classified as unsatisfactory, the current code requirements oblige one to re-design the building with significant penalty factors in the resistance values. Often the only solution is to destroy the existing facility and to build a new one. When attempting to preserve the existing building, higher levels of safety are demanded by the society and this can only be achieved by innovative system architectures. The authors propose and discuss a prototype that can be easily adopted to retrofit small educational buildings as the ones common in small municipalities. The higher performance is pursued by a special design of the control scheme, with new control devices and special control laws.

  • The harmonious lip length, residual scar and Cupid's bow width and peak with a normal side are the aims of a unilateral cleft lip repair. Also, long term amelioration without necessary of revisional surgeries may be the ideal conditions. No one method can satisfy the wide varieties of cleft lip deformities. Recently with rearrangement of paraoral muscle and some modifications, a straight line repair technique has been concerned again. Straight scar line, simplicity, and short learning curve are the advantages of the straight line technique. Here two cases of the simple straight line technique were presented and discussed for its usefulness and reliability with short reviews of previous reports.

  • The latest domestic construction sector is receiving economic damage because of defect litigation. The Concrete Crack among them has the largest component in expense of apartment house defect. Also, contradictory suggestion of appraiser is problem. To improve these problem, need objective plan that people concerned can recognize about decision sequence. Therefore, in this study, compared general defect investigation and defect decision of appraiser taking advantage of Data Dictionary analysis method. Also, deduced current problem and amelioration plan.
