The first recorded trypanosomiasis epidemic in Uganda took place at the beginning of this century in the islands and in a strip along the northern shores of Lake Victoria, which resulted in deaths of 1/3 million people. The disease was partly controlled by early 1930's and continued to occur sporadically in certain localized foci. The disease has however flared up in an explosive outbreak in Busoga district along Lake Victoria since 1977. The incidence of disease in northern district adjacent to Southern Sudan is also increasing lately. This paper describes the three month observation on the surveillance and control activities in the epidemic areas and of various health units including the Vector Control Division, the Tsetse fly Control Division, Tororo Trypanosomiasis Research Institute, medical units in Busoga, and Acholi districts. Data analysis and review were made of disease information so far collected by various health units in the Ministry of Health and district health offices. The findings may be summarized in the following: 1) A total of 12, 100 patients and 38 deaths: have occured in Busoga district since 1977 onward, and over 100 cases of diseases arc occuring in the Northern region bordering Southern Sudan. 2) the distribution of trypanosomiasis is characterized with two district patterns. The disease caused by Trypanosoma rhodesiense occurs in Busoga and is transmitted by Glossina palpalis, G. fuscipes infested in the islands and in the northern shore of forests of Lake Victoria. Another type caused by Trypanosoma gambiense occurs in Madi and Acholi in the north and is transmitted by Glossina morsitans in Savannah. 3) The house survey in Rusoga indicated that most of patients keep domestic animals in their house premises, and are engaging in either farming or fishing. Practically all the patients remembered that they had been bitten by tsetse in the field. 4) The routine diagnostic methods in the hospital laboratory is carried out through the microscopic examination of trypanosome with Giemsa stain of blood and cerebro-spinal fluid, The measurement of ESR and IgM has been used by Tororo Tryponosomiasis Research Institute for field screening.

The First stars (Pop.III stars) in the universe are expected to be formed between the recombination era at z - 1100 and the most distant quasar (z - 8). They have never been directly detected due to its faintness so far, but can be observed as a background radiation at around 1${\mu}m$ which is called the Cosmic Near-Infrared Background (CNB). Main part of the CNB is thought to be redshifted Lyman-alpha from gas clouds surrounding the Pop.III stars. Until now, the COBE (COsmic Background Explorer) and the IRTS (Infrared Telescope in Space) observed excess emission over the background due to galaxies. To confirm the COBE and the IRTS results and pursue more observational evidences, we carried out the sounding rocket experiment named the Cosmic Infrared Background ExpeRiment (CIBER). The CIBER is successfully launched on July 10, 2010 at White Sands Missile Range, New Mexico, USA. It consists of three kinds of instruments. We report the results obtained by LRS (Low Resolution Spectrometer) which is developed to fill the uncovered spectrum around 1${\mu}m$. LRS is a refractive telescope of 5.5 cm aperture with spectral resolution of 20 - 30 and wavelength coverage of 0.7 to 2.0${\mu}m$. After subtracting foreground components (zodiacal light, integrated star light and diffuse galactic light) from the sky brightness of observed five fields, there remained significant residual emission (even for the lower limit case) consistent with the IRTS and the COBE results. In addition, there exists a clear gap at 0.7 - 0.8${\mu}m$ in the CNB spectrum over the background due to galaxies according to recent results (Matsuoka et al. 2011; Mattila et al. 2011). The origin of the excess emission could be ascribed to the Pop.III stars with its active era of z = 7 - 10.

This study was conducted to establish a comprehensive grading guideline for poultry. Guidelines for sampling size and grading were determined on the basis of survey data obtained from chicken processing house. Results were summarized as follows : For application unit, most chicken processing house preferred lot unit to farm unit. Most processing house did not want the total survey method, but selection sampling. At the beginning of the grading system, chicken processing house wanted to apply the system to a particular lots for which the company requests. There were much suggestions for grading not only portion meat, but also whole chicken. Bigger processing house preferred no. $8\~12$ to be graded. Most of large-scale processing houses used more than 81 volts for stunning and cooling tanks by soaking. For shipping chicken, Large-scale processing houses used both individual and box packing while small ones only used box packing.

Allergy is a multi-factorial disease influenced by genetic and environmental factors. As the number of allergy-affected people is increasing in developed countries, there is an increasing interest in genetic predisposition to the allergy. A number of genes and chromosomal region have been identified to be linked to allergy including rhinitis, asthma and atopy. In order to understand the genetic background for the allergy-affected people, we investigated genetic predisposition among students enrolled in Busan Science Academy. Among 138 students, about 30% students had some allergy-related disorder including rhinitis, asthma and atopy. We analyzed several single nucleotide polymorphisms (SNPs) within two genes, Inter-leukin-4(IL-4) and Interleukin-4 receptor(IL-4R), which are involved in the induction of allergy reaction with the Th2 immunity. For 96 samples obtained from students, we analyzed 9 SNPs including -590 C/T and -34 C/T in IL-4, and I75V, Q576R, E375A, e406R, 5411L, S761P and S727A in IL-4R. From the analysis, these SNPs showed slight differences among normal and allergy-affected students, but these differences was not enough to predict the predisposition to the allergy. In contrast to previous reports, we could not find SNP(s) related with allergy. These results suggest that genetic tests recently performed in Korea widely have to be reassessed for its validity of genetic predisposition. [Supported by grants from MOST]

This study does present things to suggest to foreign multinational corporation or domestic corporation through the empirical study on the standardization level. If we summary this study, it is as follows. In chapter I, we did institute the problems and explain the objects and methods and system of the study. In chapter II, we did explain the universality of the culture and international advertisement. Next, we did explain the background of doing specialization strategy and standardization strategy. Also we did study the previous study about the arguements for and against these. Lsat we did institute the hypothesises as follows. - Hypothesis 1 $H_0$ : The use of westerner appeal means has been increased than 11 years before and is able to increase continuously. - Hypothesis 2 $H_0$ : The use of westerner model and knowned has been increased than 11 years before and is able to increase continuously. - Hypothesis 3 $H_0$ : The use of the English language has been increased than 11 years before and is able to increase continuously. - Hypothesis 4 $H_0$ : The use of the west short piece and background has been increased than 11 years before and is able to increase continuously. In chapter III, we did refer to the method of this study. First, we did adjust the measure of standardization index, and we did work coding it, such after the two coder did check the freguency of the appeal meanstype about the advertisement of four daily report. Then we did select eight production as high involvement production and seven production as low involvement. We did test the coder's trust degree on the such sample to be selected through the 't-test' of the SAS statistic program and regression analysis through the spss/$pc^+$ statistic program to approve the this study's hypothesises. In chapter IV, we did analysis the results of the empirical study on the high or low involvement productions. First, the results of t-test to approve the coder's trust degree is that it is same statistically attentionly the distribution of the sample between coder at 10% attention level. Next, the results of the regression analysis on eight hypothesises are as fellows. In case of high involvement production we are able to speak that the use of the English language appeal among the eight appeals is only standardized. And incase of low involvement production, we are able to speak that the use of the hard-sell appeal among the eight appeds is only standardized. Therefore we did conclude that the standardization level of Korea newspaper advertisement is low. Also this suggests that it will do plan and do the specialzation strategy or localization strategy foreign multinational corporation or domestic corporation in Korea newspaper advertisement. In chapter V, we do present the boundary of this study and new study methods.

Direct printing technology is an attractive metallization method, which has become immerging as "Green technology" to the conventional photolithography, on account of low cost, simple process and environment-friendliness. In order to commercialize the printed electronics in industry, it is essential to evaluate the electrical properties of conductive circuits using direct printing technology. In this contribution, we focused on the electrical characteristics of inkjet-printed circuits. A Cu nanoink was inkjet-printed onto a Bisaleimide triazine(BT) substrate with parallel transmission line(PTL) and coplanar waveguide(CPW) type, then was sintered at $250^{\circ}C$ for 30 min. We calculated the resistivity of printed circuits through direct current resistance by the measurement of I-V curve: the resistivity was approximately 0.558 ${\mu}{\Omega}{\cdot}cm$ which is about 3.3 times that of bulk Cu. Cascade's probe system in the frequency range from 0 to 30 GHz were employed to measure the Scattering parameter(S-parameter) with or without a gap between the substrate and the probe station chuck. The result of measured S-parameter showed that all printed circuits had over 5 dB of return loss in the entire frequency range. In the curve of insertion loss, $S_{21}$, showed that the PTL type circuits had better transmission of radio frequency (RF) than CPW type.

Little is known about the gender differences in energetic requirements of goats in early life. In this study, we determined the energy requirements for maintenance and gain in intact male, castrated male and female Saanen goat kids using the comparative slaughter technique and provide new data on their body composition and energy efficiency. To determine the energy requirements for maintenance, we studied 21 intact males, 15 castrated males and 18 females ($5.0{\pm}0.1kg$ initial body weight (BW) and $23{\pm}5d$ of age) using a split-plot design with the following main factors: three genders (intact males, castrated males, and females) and three dry matter intake levels (ad libitum, 75% and 50% of ad libitum intake). A slaughter group included three kids, one for each nutritional plane, of each gender, and all three animals within a group were slaughtered when the ad libitum kid reached 15 kg in BW. Net energy requirements for gain were obtained for 17 intact males, eight castrated males and 15 females ($5.1{\pm}0.4kg$ BW and $23{\pm}13d$ of age). Animals were fed ad libitum and slaughtered when they reached 5, 10, and 15 kg in BW. A digestion trial was performed with nine kids of each gender to determine digestible energy, metabolizable energy and energy metabolizability of the diet. Our results show no effect of gender on the energy requirements for maintenance and gain, and overall net energy for maintenance was $205.6kJ/kg^{0.75}$ empty body weight gain (EBW) ($170.3kJ/kg^{0.75}$ BW) from 5 to 15 kg BW. Metabolizable energy for maintenance was calculated by iteration, assuming heat production equal to metabolizable energy intake at maintenance, and the result was $294.34kJ/kg^{0.75}$ EBW and $k_m$ of 0.70. As BW increased from 5 to 15 kg for all genders, the net energy required for gain increased from 9.5 to 12.0 kJ/g EBW gain (EWG), and assuming $k_g=0.47$, metabolizable energy for gain ranged from 20.2 to 25.5 kJ/g EWG. Our results indicate that it is not necessary to formulate diets with different energetic content for intact male, castrated male and female Saanen goat kids weighing from 5 to 15 kg.
