It has been appeared since 1979 that the pattern of laver culture changes from household management to entrepreneurial management. The typical entrepreneurial laver culture management (ELCM) can be defined as a management by the floating aquaculturing method and mechanical processing system. Historical studies show that the ELCM could be operated only under the following condintions; \circled1 securing capital, labor and aquaculturing farm. \circled2 Leveling up of technology to combine these resources effectively. \circled3 Realizing its true value of products for good profits. In turning from household mangement to ELCM, there are some obstacles as follows ; \circled1 Uncertainty, which cannot maintein the merit of mass production because the object of laver culture is living in the sea. \circled2 Immaturity of management owing manly to the lower level of technology and scarcity of competent managers. \circled3 Social problems ; lack of aquaculturing farm, overpopulation in fishing villiage, side-job with agriculture etc. For these reasons, there has been household management with overlabor and underconsumption in fishing village. In order that ELCM can enter the stage of maturity, those problems should be solved. Because ef laver industrial inferiority, these can be solved by the support assistance of government. As the required conditions in ELCM are filled by the government policy, ELCM are increased recently in its numbers.

The effect of bath composition, plating condition and plating rate on the magnetic property of electroless Co-Cu-P deposits were investigated. With increasing $CuCl_2$ concentration in the bath, plating rate increased, while the Br value of deposit decreased sharply. Deposited surface were inferiority by the increase pH above 10.5, bath temperature higher than $80^{\circ}C$. Plating reaction had been ceased by the increase of pH above 11, bath temperature higher than $90^{\circ}C$ and under $40^{\circ}C$. The Br value of deposit was uniform with various concentration of complexing agent(sodium citrate) in the bath. The Br value of deposit was almost equal to that found by the addition of stabilizer (thiourea) and accelerator(NaF). The Br value of deposit was uniform in plating time(20min) and heat treatment temperature(below $200^{\circ}C$), and were confirmed to have adequate bath stability for practical use.

The purpose of this study is to investigate how much individual, relational, and contextual variables have an effect on the dating violence of premarital males and females. Researched are 369 male and female residents over 19 years who have experienced dating or were involved in any dating relationships in Daegu. The instruments of measurement are CTSⅡ scale and scales of relation to individual, relational, and contextual variables. The data are analysed through factor analysis, Cronbach's α, frequency, percentile, and stepwise regression analysis. The major findings of this study are as follows: First, individual variables that affect doing and victimization of dating violence are one's permission degree of dating violence, and psychological abuses experienced during childhood from one's mother. Second, relational variables that affect doing and victimization of dating violence are control toward one's partner, communication, conflict, commitment, intimacy, satisfaction of dating relationship, and feeling of inferiority toward one's partner. Third, contextual variables that affect doing and victimization of dating violence are familial relationships, friend relationships, and financial stresses.

Traditional complex joints have used to a wide variety of wooden furniture construction. Dowel joint is the most popular joint s. However design of this joint to meet specified service condition has been hampered by a lack of proven design formulas which can be use to predict their strength. The object of this study is to investigate the withdrawal strength and effect of dowel diameters in wood and wood based materials. The obtained results were as follows; 1. The relationship between withdrawal strength and dowel diameter is found to be linear. 2. Withdrawal strength of medium density fiberboard and Sepetir in end-to-side joints is superior to Antiaris, particleboard and plywood. 3. In end-to-end joints, withdrawal strength of medium density fiberboard is the most superior joint. but Sepetir. Antiaris and plywood have similarly strength and particleboard is inferiority. 4. Withdrawal strength in end-to-end joints of Antiaris and plywood is higher than in end-ta-side joints. But in end-to-end joints of Sepetir. medium density fiberboard and particleboard is similarity in end-to-side joints.

Acute Achilles tendon rupture is a frequent injury during sports and recreational activities. Treatments for Achilles tendon rupture have been controversial in recent decades. Traditionally the surgical treatment had benefit over nonsurgical treatment in terms of low rerupture rate and early functional restoration. Recently, nonsurgical treatment was found to show no statistically significant inferiority in re-rupture rate, functional outcome, and calf strength. Whereas, surgical treatment had some complications including adhesion, nerve injury, and infection. Nonsurgical treatment has been increasing due to functional rehabilitation with early weight bearing and restricted early motion. It focuses more attention on the course of caring for patients with deep discussion. There are open repair and minimally invasive repair in terms of surgical treatment. There are various techniques for minimally invasive repair of Achilles tendon, which has some advantages over the open repair. However, the optimal technique for minimally invasive repair has not been established. The number of suture strands is important regardless of suture technique.

For the purpose of finding out the differences between urban and rural primary school children aged from 7 to 12 in their physipue, 1146 (578 boys and 567 girls) urban children and 1378 (693 boys and 635 girls) rural children were obserbed by the author during 2 months period from September, 1968 to October, 1968. Following were the findings obtained from this study. 1. Physique In general, urban children showed superiority than rural children if their physique, There could be seen significant differences in their height, weight and chest-girth specially in the age group of 11 and 12. 2. Physique indices In the physique indices based on the height, the value of urban children showed superiority than rural children in relative weight but in relative chest-girth it was the other way around and there were no significant differences between these two groups in relative sitting height. The Kaup index showed higher value in urban children and the Vervaeck index in the rural children and there were no significant differences between these two groups in the Rohrer's index. 3. Comparing these figures with the Korean Standard Value, urban children showed superiority and rural children showed inferiority. Our children were inferior than the Japanese children in their physiques.

The eddy viscosity turbulence models were applied to predict the flows through a cascade, and the prediction performances of turbulence models were assessed by comparing with the experimental results for a controlled diffusion(CD) compressor blade. The original $\kappa-\omega$ turbulence model and $\kappa-\omega$ shear stress transport(SST) turbulence model were used as two-equation turbulence model which were enhanced for a low Reynolds number flow and the Baldwin-Lomax turbulence model was used as algebraic turbulence model. Farve averaged Wavier-Stokes equations in a two-dimensional, curvilinear coordinate system were solved by an implicit, cell-centered finite-volume computer code. The turbulence quantities are obtained by lagging when the men flow equations have been updated. The numerical analysis was made to the flows of CD compressor blade in a cascade at three different incidence angles (40. 43.4. 46 degrees). We found the reversion in the prediction performance of original $\kappa-\omega$ turbulence model and $\kappa-\omega$ SST turbulence model when the incidence angie increased. And the algebraic Baldwin-Lomax turbulence model showed inferiority to two-equation turbulence models.

From Jan. 1981 to Dec. 1989 eleven cases of Funnel Chest, ten were males and one was female, were underwent an operation at the Department of Thoracic and Cardiovascular Surgery. Cheonbuk National University Hospital. The age of patients ranged from 3 to 29 years old. They all had symptoms of feeling inferiority about chest deformity. The degree of concavity on the funnel chest varied in extent, and the severity which was measured by water volume filled into it varied from 20 ml to 140 ml. Nine patients were corrected by Ravitch method and two patients were corrected by the Modified sternal turnover method. The Ravitch method was more effective in asymmetrical, severe depression deformity and in children. On the other hand the Modified sternal turnover method with preservation of vascular supply of repair was more simple and more effective in case of relatively less severe, wide symmetrical depression deformity of the chest and in case of associated with congenital or acquired heart disease and disease of the ascending aorta. This method has the advantage of maintaining chest wall stability in postoperative period.
