In this local self-government era, in order to achieve real local decentralization, it is guaranteed to establish self-finances of certain administration level. Nowadays Local equalization scheme is carried out for insuring regional equal development and efficiency and effectiveness of administration and for solving vertical horizontal problem of unequal finance in local government. Local equalization scheme is the system to guarantee the financial source so that all local self-governing organizations can obtain national minimum standard while correcting the unbalance of finance and maldistribution of tax revenue source between regions. This paper presents the directions of improvement so that national subsidy and local tax can contribute to the finance balance of local self-governing organization in the uncertainties of future finance with weak financial ability. Consequently, it is required to operate the system according to balance principle by adjusting the operation form and distribution type such as national subsidy and local tax.

The purpose of this study was to compare the effect of the Z-track intramuscular injection technique with the effect of the stand and intramuscular injection technique on the severity of discomfort and leasions at the injection site. The subjects of the study were 20 patients with only early tuber culosis excluding another abnormalities (a akin rash, allergy to topical use of alcohol, jaundice, edema, neurosensory abnormality, coagulation defects, obesity and thin). Data collection was done from Feb. 1 to March 15, 1988 by means of Korean Pain Measurement Tool, Visual Analogue Scale, and Objective measures of injection site lesions. The results of this study were as follows ; 1) Hypothesis 1 ; “The severity of subject discomfort is less following administration of the Z-track intramuscular injection technique than following administra tion injection technique.” was not sopported 2) Hypothesis 2 ; “The degress of severity subject discomfort is less following administration of the Z-track intramuscular injection technique than following administra tion of the standard intramuscular injection technique.” was not supported. 3) Hypothesis 3 ; “The severity of injection site lesions is less following administra tion of the Z-track intramuscular injection technique than following administration of the standard intramuscular injection techniques.” was not supported. 4) The terms that were selected included factor II (mild-moderate pain) of Ratio Scale Measuring Pain using Korean Pain Terms. In conclusion ; it was found that there was not a difference from the severity of subject discomfort between two groups, but the degress of severity of subject discomfort about following administration of the Z-t-rack intramuscular injection was tended to be declined. Therefore further studies suggest that the Z-track intramuscular injection technique can decrease the severity of discomfort in persons receiving frequently intramuscular injections. First of all, it is necessery to be developed an effective tool of discomfort measurement for the intramuscular injection in Korean.

To cope with increasing of vegetables and flowers consumptions, horticulture facilities have been modernized. Korea government recently announced construction plan of new greenhouse complex at reclaimed land. However wind characteristics of reclaimed land is totally different from those of inland, wind pressure on greenhouse built in reclaimed land should be carefully evaluated to secure structural safety on the greenhouse. In this study, as a first step, wind pressure coefficient and local wind pressure coefficient on even-span greenhouse were measured using wind tunnel test. ESDU was adopted to realize wind characteristics of reclaimed land such as wind and turbulence profiles. From the wind tunnel test, when wind direction was 0 degree, it was concluded that KBC2009 standard underestimated scale of wind pressure coefficients at roof area of greenhouse whereas NEN-EN2002 standard underestimated those at every surface of greenhouse. When wind direction was 90 degree, both standards did not well reflect the characteristics of wind pressure distribution. From the analysis of local wind pressure coefficients according to wind direction conditions, design of covering, glazing bar of greenhouse where large effects of the local wind pressure were estimated should be well established. Wind pressure coefficients and local wind pressure coefficients according to parts of the greenhouse were finally suggested and these results could be practically used for suggesting new design standards of greenhouse.

This study is to discuss the effect of the liquid type high early strength agent considering early strength, developing strength, and economics of the concrete using admixtures. The powder type high early strength agent does not helpful because the field application is not available such as the problem of mixing process and rack of economics. To make up these subjects, the plain mixture contains the standard type AE water reducing agent, and the types of the agents are the standard type AE water reducing agent(P),liquid type high early strength agent(AD),poly carboxylate high early strength type AE water reducing agent(E1), and naphthalene + melamine high early strength type AE water reducing agent(E2). As the Contents of the agents, E1 and E2 is two types each cases, and P is one type to satisfy the target fluidity and air content, AD is three types as 0.5, 1.0,and 1.5%. In the case that AD is mixed, the fluidity is decreased, but air content is increased. For increasing strength of the early age, using OPC is more effective than FA and BS for increasing the early strength of the concrete, and if the air content is secure as plain, the effect of the developing strength can be increased because the air content is increased about 2% in the case that AD is used.

Recently, the Korean government announced a new development plan for a large-scale greenhouse complex in reclaimed lands. Wind environments of reclaimed land are entirely different from those of inland. Many standard books for ventilation design didn't include qualitative standard for natural ventilation. In this study, natural ventilation rates were analyzed to suggest standard for ventilation design of venlo type greenhouse built on reclaimed land. CFD (Computational Fluid Dynamics) simulation models were designed according to the number of spans, wind conditions and vent openings. The wind profile at a reclaimed land was designed using ESDU (Engineering Sciences Data Unit) code. Using the designed CFD simulation model, ventilation rates were computed using mass flow rate and tracer gas decay method. Additionally computed natural ventilation rates were evaluated by comparing with ventilation requirements. As a result of this study, ventilation rates were decreased with increasing of the number of spans. Ventilation rates were linearly increased with increasing of wind speed. When the wind speed was $1.0\;m{\cdot}s^{-1}$, only side vent was open and wind direction was $45^{\circ}$, homogeneity of ventilation rate at 0~1 m height is the worst. Finally, chart for computing natural ventilation rate was suggested. The chart was expected to be used for establishing standard of ventilation design.

Licorice(Glycyrrhizae Radix et Rhizoma) is recorded as the root of Glycyrrhiza uralensis Fischer or Glycyrrhiza glabra Linne or Glycyrrhiza inflata Bat.(Leguminosae) in Korean Pharmacopoeia $9^{th}$ edition (KP9) and Chinese Pharmacopoeia 2005(CP2005), Glycyrrhiza uralensis Fischer or Glycyrrhiza glabra Linne in Japanese Pharmacopoeia 2005(JP2005). It is established the content standard of Glycyrrhizin 2.5 % and liquiritin 1% in KP9 and CP2005. But, according to the reports, all Licorice species were not sufficient for content standard of liquiritin 1.0% for licorice in KP9 and CP2005. It shows different content of liquiritin among G. uralensis, G. glabra and G. inflata. Also, it was reported liquiritin, liquiritin apioside are transformed into liquiritigenin by human internal flora. Therefore, we have studied for the pre-treatment condition and analytical method of liquiritigenin; It was good efficinet in 2M HCl reflux(1 hr) for hydrolysis and in methylene chloride for solvent fractionation. And 1% acetic acid in DW(A) and acetonitrile(B) with gradient condition as a mobile phase was most effective in HPLC analytical condition. According to these experimental methods, we have anlayzed content of liquiritigenin about 77 Licorice sample. In this research, it was also examined the content of liquiritin and liquiritigenin for Glycyrrhizae Radix related growing area. According to the results, we suggested the content standard of glycyrrhizin more than 2.5%, liquiritigenin more than 0.7%(after hydrolysis) of licorice.

The growth rate, feed conversion efficiency and carcass characteristics of nine native Malpura (M) and eight Awassi ${\times}$ Malpura half bred (AM) male lambs were compared under intensive feeding on 60:40 concentrate and roughage based composite feed. Weaning body weight was similar in the two genetic groups while finishing body weight, total body weight gain and average daily gain during the experiment were higher (p<0.01) in AM than M lambs. The feed conversion efficiency was lower in M than AM lambs with 15.7 and 19.8 per cent feed conversion efficiency, respectively, in the two genetic groups. The dressing yield in terms of preslaughter weight or empty live weight was however similar in the two genetic groups. The loin eye area was also greater (p<0.01) in AM than M lambs. The cutability was similar for the two groups amounting to 33.2, 13.3, 13.2, 23.3 and 16.6% of half carcass, respectively, for leg, loin, rack, neck and shoulder and breast and foreshank. On an average the separable lean, fat and KOH bone content of the half carcass were 48.3, 16.8 and 23.3% for native M and 54.1, 15.0 and 19.0% for AM lambs, respectively. It is concluded that growth rate and feed conversion efficiency were better in Awassi ${\times}$ Malpura half bred than native Malpura lambs while dressing yield and cutability of standard cuts were similar in the two genetic groups.
