The experimental study on the air flow in the square duct with ratio of 1(40㎜×40㎜) and 4,000㎜ long is carried out to determine the entrance length with the velocity profiles and velocity waveforms by using a hot-wire anemometer with data aquisition and processing system. The entrance length equation of oscillatory flows is L = Q Re_os. The experimental costant of the square duct is 0.00804, when the dimensionless angular frequency is 7.16.

The velocity waveforms of oscillatory and pulsating flows are investigated experimentally in the range of laminar, transitional and turbulent flows in the fully developed flow region of a square duct. In a square duct, the experimental study for the air flow was carried out to measure the velocity waveforms by using a hot-wire anemometer. The flows are classified into laminar, transitional, and turbulent flow regions in the transverse-directional positions. The amplitude of the velocity waveforms near the wall is smaller than that of the center line.

The effects of compound fertilizers on the yield and growth characters of the paddy rice variety, Man-kum, were studied. The length of culm and panicle, the weights of 1000 grains, empty grains and rice screenings, and the quantity of protein and total nitrogen content increased significantly. The percentage of ripeness and hulled or unhulled rice decreased the overall acceptability of fertilizers.

This study aims to examine the growth and yield of each variety of cottons. The experiment was carried out at the experimental field of Chinju National University from May till December 1995. 1. The plant height and the length of stem internode were similar in each variety. The number of fruiting branches showed difference of 2 to 9 between varieties. 2. The days to decrescence of boll tended to be shortened in the variety whose days to flowering are long. The number of flowering per plant was smallest in Tomcot SP 22 variety(46). The number of bolls per plant was largest in Jackson Strain Cottomol (47). 3. Each variety showed similar stem diameters. The total weight was heaviest in Seosan up Bongnamdong variety(510g), and the root weight per plant was heaviest in Insung Hyunsan variety (48g). 4. The boll length showed a little difference between varieties; the largest length was shown in Tomcot EP 22(5.24cm). The boll width was similar; Sooncheonsi variety was narrowest(2.89cm). The boll weight showed a great difference between varieties according to boll length and width. 5. The seed and lint weight per boll and the lint weight per boll showed a little difference between varieties. They seemed to be in direct proportion with each other. The lint percentage per boll was lowest in Quall(26.29%). 6. The number of bolls per plant was different by 10. And the 100grain weight also showed the difference of 1 to 4.19g. 7. Each variety showed a great difference in the picked cotton; Seosanup Bongnamdong variety produced the heaviest picked cotton(214Kg). In the stalk-cut cotton, Seungjugun variety was lightest(51Kg). The total yield was largest in Seosanup Bongnamdong variety(311Kg). 8. Variance analysis showed a significant difference in all of the characters except the plant height, the number of fruiting branches and the number of total weight.

Shear stress distribution of developing transitional pulsating flows are investigated analytically and experimentally in entrance region of a square duct. A system of conservation equations for pulsating duct flows is solved analytically by using the linearization of non-linear convective term. The experimental study for the air flow is carried out to measure the shear stress by suing the hot-wire anemometer with data acquisition and processing system. The results obtained from analytical and experimental studies are summarized as follows : (1) The distributions of shear stress for the transitional pulsating flow increase abruptly in z' ≒ 0.8~1.0. (2) The shear stress of inflow and outflow for the transitional pulsating flows is symmetrical, the largest at ωt/(π/6)= 3 and 9, and the smallest at ωt/(π/6)= 0 and 6. (3) The distributions of shear stress in entrance region of a square duct are larger than those in downstream region.

A lot of large scaled and luxurious hotels have been built since the memorable 1988 Seoul Olympics, and they will continuously expend their business scope to cope with the market opening and internationalization looking forward to 21st century. Generally speaking, the two major parts of hotel management are guestroom and food & beverage sales. Until recently, the role of food & beverage parts of a deluxe hotel received minimal emphasis and little recognition for its role in helping to attain profit objectives and productivity improvement goals. Lately, however, it has developed into a sophisticated function in most successful hotels and managers has responded to the changing need, desires, and expectations of guests while recognizing the need to consider of food & beverage parts. The fundamental purpose of this study is to provide useful and timely management of food & beverage parts related to manpower efficiency, productivity improvement, practical help for the high positioned managers, and profit improvement which is ultimate goal of the deluxe hotels in Pusan. This study is composed of five chapters : Introduction, The theoretical background of food & beverage parts of tourist hotels, An analysis of the management realities in food & beverage Parts of deluxe hotels in pusan, A study on the productivity improvement of deluxe hotels in pusan, and Results. The purpose, approach method and scope of this study are introduced in Chapter 1. Chapter 2 states the significance development of food & beverage paπs. Chapter 3 presents the realities, facilities, manpower status, organization and management as a whole. Chapter 4, the most important one in this study, discusses what the problems are, how to improve the productivity, and what the prospects of food & beverage parts of deluxe hotels in Pusan are in great detail. Chapter 5 states brief results, limitation and further suggestions of this study.

The heterosis effects were analyzed with the following results. 1. 100-seed weight was heterosis showed with 1.11% in F_1 and 1.59% in F_2 of generations. 2. Seed cotton weight per boll was negative heterosis showed with - 1.30% in F_1 and 1.47% in F_2 of generations. and Lint weight per boll was significantly heterosis showed with 1.22% in F_1, 2.96% in F_2 of generations. 3. Picked cotton height heterosis showed with 6.67% in F_2 of generation than 0.53% in F_1 of generation, In the case of stalk cotton high heterosis showed with 10.01% in F_1, 5.60 in F_2 of generations, In the case of total cotton was the same showed with 3.04% in F_1 and 5.28% in F_2 generations.

A country's eating habits are closely related to the countη s climate, custom and culture, and the level of the dietary life is greatly influenced by the level of the national income. Specially, A food service industry is closely connected with the economic conditions of the country. Before IMF, in our countη the frequency and the cost of eating out have increased in more than 15% per year. For this reason, a food service industry was in a prosperous condition. After IMF, however, economic difficuIties have caused severe damage to food service industries on the country. The many unemployed people because of IMF are entering into food service industries. But they are often starting a new food business without the know-how and the enough experience about food service industry. This has caused another failure. Accordingly, in this paper, r d like to suggest several development plans in order to help the men who will start to work or are working in food service industries. 1st, You should have on interest on business. 2nd, You should create a distinguished marked individuality. 3rd, You should have concern and passion of business. 4th, You should try to reduce the cost.
