국방분야에서 M&S 기법은 분석, 훈련, 획득 등 다양한 목적으로 활용되고 있으며 그 중요성은 더욱 증가하고 있다. 무기체계의 종합군수지원(ILS)요소 개발을 위한 RAM분석 시 M&S 기법을 활용하면 수리적인 기법만으로는 분석하기 어려운 시스템의 다양한 변수와 제약사항을 고려한 분석이 가능하다. 무기체계의 RAM분석을 위한 ILS M&S도구를 설계하기 위해서는 M&S의 목적 설정, 무기체계의 특성 및 유사 M&S Tool 기능 분석 등의 활동이 선행되어야 하며 이를 바탕으로 실제 현실을 프로그램으로 구현하기 용이한 형태의 수학적, 논리적 언어로 모델링해야 한다. 본 논문에서는 'OO유도무기체계'의 배치부터 폐기 시까지 발생하는 운용, 저장, 점검, 고장발생, 정비 등 제반 군수지원활동을 모의하여 유도무기체계의 수명주기 동안의 RAM 특성을 예측, 분석할 수 있는 M&S 도구의 모델링 과정을 제시하고자 하며 이는 유사 M&S 도구의 개발 시 참고자료로도 활용 가능할 것이다. M&S techniques are utilized for various purposes on the national defense, and its importance is increasing than ever. For analyzing RAM (Reliability, Availability and Maintainability) of weapon system, using M&S techniques can be more effective and practical way than deterministic approach, because M&S approach can consider uncertain variables and various constraints in the ILS (Integrated Logistics support) field. For design of ILS M&S, we first set up a purpose of M&S, attributes of real system and other similar ILS M&S tool. Then, we convert real system into model which consists of mathematical formula and logical expression. In this thesis, we introduce modeling procedures of M&S that describes total life cycle of 'OO guided weapon system' and the contents proposed in this paper can provide references for developing other M&S tool.

This study was conducted to investigate the sex ratio between the natural born pigs and B-body test sperm, which the data were obtained from a total of 1.242 pigs born at Swine Farm, Jeil Sugar Co. And it was attempted the sedimentary and galvanic separation. of X-and Y-bearing spermatozoa with 4 boar semens at College of Agriculture, Seoul National University. The results obtained were as follows; 1. The natural sex ratio of pigs born was about 50%, and B-body test sperm was a-so about 50%. It was, therefore, statistically non-significant differences of the sex ratio between the natural born pigs and B-body test sperm. 2. The B-body test sperm obtained from Fractionated semen was similar to B-body sperm of control 3. Spermatozoa of swine were separated into different fractions by sedimentation. B-body rest sperm to anode was 53.70%, and the B-body from bottom was 33.43%. 4. The swine semen could separate X- and Y-bearing sperm by galvanization without interfering the sperm liability. In galvanization of sperm, the percentage of the B-body sperm induced to anode was 60.4%, while the sperm to cathode was 28.15%. This experiments with seminal galvanization and sedimentation for the separation of X- and Y-bearing sperm have been exclusively conducted with swine. Since the data presented in this report were still unstable, more detail research would, so far, be needed.

This experiment was carried out to find the best castration method for economical body gain and the improvement of the pork quality by preventing the sex odor. Including three female pigs, twelve heads of pigs, 50days old, were assigned into four groups, three pigs each by the completely randomized design. Except female group for control, the rest three groups were treated by the different castration; complete castration, cryptorchidism (short scrotum), and partial castration, and fed for 21weeks under the sane feeding condition. During the feeding period, the body gain and he feed consumptions were checked periodically for daily gain and feed efficiency. After the finishing of feeding, all the pigs were slaughtered and the carcass data, were collected and analyzed. The results obtained were summarized as follows; 1. The average total gain of completely castration, cryptorchidism, partial castration and female groups were 73.17, 81.50, 78.57 and 60.33kg respectively. However, there were non-significant differences for daily gain among each groups. 2. Feed consumption was non-significantly differed between four groups and they shown the same tendency in feed efficiency and body weight gain. 3. Dressing percentage was non-significant difference among the treatments. The whole average of dressing percentage was 68.3% 4. The ratio of carcass width(W) to carcass length (L) was about 41% in cryptorchidism and complete castration, but 46% in partial castration. 5. The backfat thickness indicated slightly lower in cryptorchidism (2.33㎝) than partial castration (2.63㎝), which was slightly lower than commonly-fattend swine. In loin eye muscle area, cryptorchidisn (31㎠) showed a little greater than complete castration (29㎠) and partial castration (30㎠).

The combination of the acid-alkali method and eletrophoresis for X-and Y-sperm separation of boar semen was performed We used lactic acid and sodium bicarbonate in acid-alkali method, and electrophoresed at 2.5V and 200 μA. The results obtained were summarized as follows : 1. The frequency of appearance of B-body from alkali treatment of whole semen was significantly higher than that from acid treatment. 2. The frequency of appearance of B-body from alkali treatment at the anode electrode was significantly higher compared with that from acid treatment at the same electrode, while that from acid treatment at the cathode was slightly higher than that from alkali treatment at the same electrode. 3. According to time of treatment, Appearance of B-body from alkali treatment at the anode after electrophonesis was decreased, and the result from acid treatment at the same condition was the opposite, while appearance of B-body from alkali treatment at the cathode after electrophoresis was not changed and that from acid treatment at the same condition was increased. 4. Appearance of B-body from alkali treatment at the anode for 5-10minutes showed the most useful result which was higher than the result (51.9%) from electrophoresis alone by 3 %.

Warfighting experimentation is an important process for identifying requirements against changing military environment and for verifying proposed measures for reforming military service. The wargame simulation experiment is regarded as one of the most effective means to warfighting experimentation, and its importance is increasing than ever. On the other hand, the results of wargame experiments could be unreliable due to the uncertainty involved in the experimental procedure. To improve the reliability of the experimental results, systematic experimental procedures and analysis methods must be employed, and the design and analysis of experiments technique can be used effectively for this purpose. In this paper, AWAM, a wargame simulator, is used to optimize the organization of operational troops. The simulation model describes a warfighting situation in which the 'survival rate of our force' and the 'survival rate of the enemy force' are considered as responses, 'the numbers of weapons in the squad' as control factors, and 'the uncontrollable variables of the battlefield' as noise factors. In addition, for the purpose of effective experimentation, the product array approach in which the inner and outer orthogonal arrays are crossed is adopted. Then, the signal-to-noise-ratio for each response and the desirabilities for the means and standard deviations of responses are calculated and used to determine a compromise optimal solution. The experimental procedures and analysis methods developed in this paper can provide guidelines for designing and analyzing wargame simulation experiments for similar warfighting situations.

In order to study on the development of the spermatogenic function and the sexual maturity between the Korean purebred and three-way crossbred ((Angus × Korean purebred) × Holstein), this experiment was conducted to investigate the testicular development and the spermatogenetic function by means of repeating biopsy at one month intervals from one to 9 months of age with 6 Korean purebreds and 3 three-way crossbreds. 1. In the testicular development, the scrotum circumference of the Korean purebred and three-way crossbred increased steadily with increasing age. The scrotum circumferences of the Korean purebred and three-way crossbred were 19.4 ㎝ and 28.9 ㎝ at 9 months of age, respectively, and doubled to one month of age. The testicular width and length increased rapidly from 6-7 months of age, but the differences between two groups were not statistically significant. 2. The seminiferous tubules in the testis of two groups, solid at 3 months of age, increased appearently in diameter at 5 to 6 months of age, but were not reached mature size. 3. Only gonocytes and indifferent supporting cells were present in the tubules at 3 months of age and spermatogonia appeared from 5 months of age, spermatocytes increased rapidly from 6 months of age and spermatid were seen for the first time in the 7 months old Korean purebred and three-way crossbred. On the basis of the above results it is concluded that sexual maturity of three-way cross bulls was somewhat earlier than the Korean bulls, but the difference of two groups was not significant.

The primary objectives of this study were to observe (1) the variation of functional activity between the right and left ovaries in the dairy cows, and (2) the effect of age to the variation of functional activity and (3) environmental effects around the ovary uterine horn to the rate of fertilization. Data were obtained from 1218 mature follicles and 155 pregnant cows. The result obtained were as follows; 1. The right ovary was more active than the left. And the frequencies of follicle maturation in the right and left ovaries were 763(62.46%) and 455(37.36%) follicles respectively. The variation of this two frequency is significant at 1% level. 2. Under the 6 years the frequencies of follicle maturation in the right and left ovaries were not affected by the age. As compared over the 7 years with under the 6 years, the age did not significantly affect the variation of ovulation frequency between the right and left ovary. 3. The environments around the left ovary and uterine horn did not significantly affect the rate of fertilization and implantation of fertilized egg.
