Reintroduction programs have been promoted across the world to recover and rehabilitate endangered birds through ex situ captive breeding and releasing to the nature. The ultimate aims of these reintroduction programs are recovery of sustainable populations in natural habitats. To ensure the success of the reintroduction programs, it is necessary to examine the followings in order to increase the success rate of releasing along with the development of captive breeding techniques: 1) Adequate habitat provision, 2) adaptability of captive-bred individuals, 3) survivability of released individuals, and 4) social interest and will. Before releasing captive-bred individuals, it should be reviewed whether there are habitats in which the limiting factor is removed, and assessed their long-term safety. The quantity and quality of the released individuals must be considered to increase the chances for mate selection, maintain genetic diversity, and acquire the ability to adapt to the wild. The release method must be decided in consideration of characteristics of the target habitats and individuals, and rational means such as careful observation, evaluation, and feedback must be provided throughout the release process. For the long-term success of recovery projects, social awareness, sustainable support, and related experts are needed. Satisfying these criteria can help to increase the success rates of reintroduction programs. For the bird reintroduction program in the future, the feasibility of the methods and procedures must be closely reviewed before starting.

After accepting the modernized western culture, we, the Koreans, had traditionally patriarchal valuation on the family life, which has been changed into modernize on in these days. Under these circumstances, we examined into family consciousness of workmen, office workers and student of universities in Pusan with questioning papers by inquiring their general views of family, marriage, family planning , and inheritance. The results obtained can be summarized as follows. 1. General views of family 1)Most of them prefer nuclear family to gross one in structure of family. In decision of family's affairs, the lower educated persons want an unilateral relationship, which means unconditional obdience to their parent's opinion. they are more concerned about the profit of the family than that of individual. on the other hand, they want 2-generations nuclear family system. 2) Concerning children's future affairs, they want compromising method. 2. Views of Marriage 1) Date with the other sex motivated their desire to improve social adaptation and social association. 17-19 year old students regard date as a preparatory stage of marriage. They consider it most desirable date to enjoy free conversation each other. They hope their date partners are high educated. 2) The conditions of mate selection are in order character, health, vitality in living, appearance and education. The less educated placed an emphasis on vitality in living. 3) They are not much interested in marital harmony. If parents are against their marriage an account of bad marital harmony, they will take into consideration about it. 4) They wish to keep purity before marriage, as possible. They want engagement period of 6 months. Any agreeable reasons shall compel them to break off their appointment. 5) they consider it ideal for mate's age to be 26-30 years old, and also think it affirmative to follow their parent's agreement in marriage. It is considerable that they put off their marriage only because they have lots of work to do before marriage. 6)Marriage declaration is to be made on the wedding day. It still exists that they don't want to marry when they are inth same surname and family tree. But it is clear that they don't regard it as the reason of breaking off the betrothal. 3. Family Planning 1) They are willing to agree to the campaign "just two is enough". They want a son and a daughter. Even though they have two daughters, they won's bear child to get son. 2) the lower educated persons are ignorant of the method of birth control. 4. Inheritance 1)Most of them say householder inheritance is to be kept up continuously. It is reasonable that anyone who can afford to perform religious service should bear it responsibility. 2)They don't want the difference in inheritance as the conscious to the conscious of the equality of the sexes spread widely into our society, but it is worthy of notice that some of them still don't mind unequal treatment. 3) When they have no child, the property inheritances are in order his wife and his parents. According to above mentions, we conclude like this: Their consciousness of marital harmony, marriage, family planning and inheritance shows definitely passive rationism in the transitional stage which is mixed with western individualism and traditional feudalism. On account of being lack of steady fast self-conscience, they can not make their positive reaction on anything. Finally, we should make every possible efforts to have our firm self-conscience through the re-education.

The purposes of this study were to determine the general trends of the family value orientations FVO of overseas Korean women, to investigate differences in related variables, and to examine the relationships between FVO and the related variables. The subjects were 1,413 Korean women over 20 years living abroad in America (363 women), China (555), and Russia Central Asia (495 women). The subjects completed a questionnaire on FVO. Data were analyzed using SPSS. The major findings were as follows: 1. Korean-American women's FVO were modernistic, Korean chinese women's were traditional, and Korean women in Russia Central Asia showed neither traditional nor modem FVO. 2. The overseas Korean women's values were different from the value's dimension. 'Filial piety' showed very traditional value orientations, but 'preference of son , and 'mate selection 'showed modem FVO. The dimensions of FVO were different according to the living region. 3. The FVO values were different according to age, and period of education. Korean-American women's FVO were positively related to age, health condition, and the cognition of being Korean. Korean-Chinese women's FVO were related to age, living condition, marital and parent-child relationship, self-respect, and life satisfaction. Russia Central Asia women's FVO were correlated with age, period of education, living condition, health condition, the cognition of being Korean, marital and parent-child relationship, self-respect, and depression.

Recipients are an integral part of embryo transfer and they are expensive to maintain as a good recipient. Recipient management is one of the most important components in a successful embryo transfer program. Management includes selection and subsequent care of the animals. A good recipient is basically on "open" cows or heffers whose reproductive tract is capable of receiving one or two embryos and incubating it to term. Potential recipients should be always be healthy and cycling normally ranging from 18 to 23 days. A thorough veterinary examination is recommended for candidate of recipients and cattle for questionable health should be eliminated from the recipient herd. Age and size of recipients are particularly important considerations when heifers are used, because of most embryos available for transfer are from large dams and sires. Body condition can influence a recipient's production, reproduction and health. Obese and underconditioned cattle should be avoided for use. Transfer of fresh embryos especially requires precise synchronization of donors and recipients. For estrus synchronization, PGF$_2$$\alpha$ is injected twice 10 to 12 days apart and short4erm progestagen treatment is applied to potential recipient cattle by coil into vagina (PRID) or ear implant (Synchro-Mate-B). The highest pregnancy results are achieved in recipients at exact synchrony with donors or 12 to 24 hr earlier than donors. Estrus detection is a major factor in breeding efficiency. High accuracy can be achieved by use of heat mount detection alds or by obserbing cattle for 30-minute peroids 3 times daily. Assay progesterone in milk can be used to discrIminate between pregnant and nonprenant recipients. Rectal palpation on day 35 to 70 after is an accurate and safe method of pregnancy diagnosis. Embryonic mortality in recipients may be associated with factors such as high environmental temperature and nutritional or lactational stress in early lactation period. Achievement of short calving interval requires concentrated management activity during the first 90 days following calving. Acceptable candidate for a recipient should be routinely vaccinated for infectious diseases. Proper nutritional programs according to NRC requirements and body condition scoring system for recipient cattles are vital to the ultimate success of an embryo transfer program.r program.

현재 국내에서 적용되고 있는 입력중심형의 사업추진 절차(Input-oriented procurment process)하에서 민간투자사업은 민간의 창의성 도출과 민간 자본의 유입이라는 본래의 장점을 살리고 있지 못해 영국 등 선진국의 민간투자사업 등에서 추진되고 있는 성능중심적 방식(Performance(or Output)-oriented Procurement Process)의 도입이 시급한 실정이다 현재 국내에서는 민간투자사업의 본래 목적인 민간의 창의성 및 효율성으로서 인프라 서비스를 제공한다는 취지에 부합하지 못하는 면이 있다. 이러한 국내의 현황과는 달리 국외에서는 특히 영국을 중심으로 정부가 필요한 서비스를 공급하기 위한 새로운 개념으로서 서비스를 제공하기 위해 건설하는 시설물을 어떤 작업을 통하여 만드는가에 중심을 두는 것이 아니라 그 시설물이 제공하는 최종 목표인 서비스의 성능에 중심을 둔 개념으로 각 14개의 추진절차상에 성능중심적 개념을 도입하고 있다. 본 연구에서는 이러한 성능지향적 추진체계를 성능중심적 방식으로 정의하고 민간투자사업의 성능중심적 방식도입에 관한 기초연구로서 PSC(Public Sector Comparator)의 활용방안과 도입방안을 제시하였으며 향후 실질적인 도입을 위해서 기술분야와 제도 및 법령분야에서 구체적인 연구 및 실무작업이 필요할 것으로 사료되며 향후과제로 제시하였다.
