Reproduction in ruminant species is a highly complex biological process requiring a dialogue between the developing conceptus (embryo-fetus and associated placental membranes) and maternal uterus which must be established during the peri-implantation period for pregnancy recognition signaling and regulation of gene expression by uterine epithelial and stromal cells. The uterus provide a microenvironment in which molecules secreted by uterine epithelia and transported into the uterine lumen represent histotroph, also known as the secretome, that are required for growth and development of the conceptus and receptivity of the uterus to implantation by the elongating conceptus. Pregnancy recognition signaling as related to sustaining the functional lifespan of the corpora lutea, is required to sustain the functional life-span of corpora lutea for production of progesterone which is essential for uterine functions supportive of implantation and placentation required for successful outcomes of pregnancy. It is within the peri-implantation period that most embryonic deaths occur in ruminants due to deficiencies attributed to uterine functions or failure of the conceptus to develop appropriately, signal pregnancy recognition and/or undergo implantation and placentation. The endocrine status of the pregnant ruminant and her nutritional status are critical for successful establishment and maintenance of pregnancy. The challenge is to understand the complexity of key mechanisms that are characteristic of successful reproduction in humans and animals and to use that knowledge to enhance fertility and reproductive health of ruminant species in livestock enterprises.

The purpose of this paper is to propose directions for urban greening and nature conservation in small-to-medium-sized cities in Korea for implementation of the Local Agenda 21 (LA 21 hereafter). In this paper, the status of implementation of the LA 21 in both Korea and Japan have been examined. In addition, the green-related plans of both countries have been compared. The cities of Jeonju and Sagamihara were chosen as examples to compare. The result of the research is as follows: 1)With regard to the responsible bodies, in Korea, the implementing plans were initiated by the environment-related authorities of local governments while, in Japan, the plans of action were initiated through consultative committees reflecting opinions from citizens and business entities. 2)Concerning the status of implementation of LA 21, the city of Jeonju has adopted a plan of action and then implemented the plan through a consultative body without adequate legal ground. On the other hand, the city of Sagamihara has enacted a local ordinance to implement the LA 21 It was learned that the newly enacted ordinance has positively been interrelated to existing environmental plans. 3)Regarding urban greening and nature conservation plans, the city of Jeonju has focused on comprehensive measures to preserve and restore ecology while the city of Sagamihara has clearly suggested educational purposes in its plans in addition to preserving and restoring ecology. 4)In terms of support by law or legal system concerned, it has been teamed that, compared with Japan, Korean plans have not been properly supported by law or the legal system to urban greening and nature conservation plans. The same was shown in the city of Jeonju as compared with the city of Sagamihara. As for future directions, the follow are proposed: 1) establishment of a local Committee on Sustainable Development, 2) enactment of relevant and regulations such as the Master Plan of Parks and Green Open paces, 3) establishment of ecological greening plans.

The purpose of this study was to propose the developmental direction for small libraries based on a set of various situational analysis of small libraries in Seoul. By analyzing the operational status of the autonomous regions of different operating methods, we also pursued qualitative enhancement of small libraries by autonomous district by proposing optimized operation methods. As a consequence of the study, it was analyzed that the public and private libraries need to be distinguished in consideration of the characteristics of operation according to the operating entity rather than uniform budget support and guidance management. That is, the small libraries scattered throughout Seoul were founded by the principal of their establishment for the purpose of providing knowledge information and reading culture service within the public activity area. Therefore, if Seoul intervenes and manages under the current situation, where the libraries are operating independently in accordance with the purpose of establishment, regardless of whether they meet the user requirements or not in terms of quality or quantity, various problems may be caused. In this background, it seems appropriate to restrict the library management in line with relevant regulations.
The number of welfare foundation to which local governments have contributed is 20 as of December, 2013. As the role of local governments tends to be more stressed than that of central government to achieve the fulfillment of local residents' welfare, the establishment of welfare foundation by local governments is increasing. Considering that the establishment of welfare foundation will increase in future due to the reinforcement of local autonomy it is evident to study the means to operate welfare foundations transparently and effectively. In this situation there has been neither review on the problems in the operation of welfare foundations until now nor study suggesting its improvement direction or activation plan. Therefore, this study delves into the current status of nation-wide welfare foundations and several problems occurred in the implementation process, and it is aimed to achieve the original goal of welfare foundations and the activation of welfare foundations.
As the interest in environmental problems increased, the guideline of effluent qualities becomes strict and the amount of sludge produced from the wastewater treatment facilities steeply increased. The revised Korean acts prohibit the direct reclamation of the sludge exhausted in sewage treatment works from 2003, and the ocean dump of sludge will be also prohibited from 2012. Therefore, the sludge must be recycled, incinerated or composted. To properly perform the utilization and disposal operations, the establishment of well-defined procedures for the characterization of sludge by physical, chemical and biological method and setting up of guidelines for different treatment and disposal routes has become necessary. However, there have not been such standardized methods for sludge characterization in Korea. This review analyzes the present status of establishment and problems of sludge characterization method of Korea. Finally, it was proposed total 15 items of standardized characterization methods suitable to our country for proper sludge recycling and disposal, which was based on the more systematic standard methods of Germany (DIN 38414) and those of advanced nations.

The modular apartment has been completed for the first time in Korea through the national research and development (R&D) project in December 2017, and 30 households moved in. Although conditions such as technicality and constructability have to be satisfied to adopt and spread the modular apartments in the future, economic feasibility is the most important factor among the conditions. The economic feasibility of modular apartments can be compared with that of existing reinforced concrete (RC) structure apartments. It is highly important to reduce the construction cost through standardization above all. The standardization refers to establishment of national design standards and principles, and it is important for manufacturers and building companies to comply with those standards and principles. The modular construction (MC) skill in Korea is at an early adoption stage and the MC market is not widely expanded yet. Thus, the application of the MC design, which is the basis of the standardization, has not been widely accepted. However, related R&D projects are now performing mainly by the Ministry of Land, Infrastructure, and Transport to promote modular apartments in recent years and the design standardization standard (draft) is now prepared to be notified as a result of the steady research. Furthermore, pilot complexes for demonstration purpose are under construction, starting from public rental apartments. Thus, MC method-applied public rental houses will be spread in near future. This study aims to investigate the current design status in the Ga-Yang Housing as a pilot modular complex to produce and supply more economical and efficient modular houses, and analyze the problems by comparing the design standardization standards with pre-notified design standardization standards and summarize the modifications between them thereby presenting foundational data for establishment of the design standardization in the modular business industry.

The purpose of this study is to examine the current status of university library operation through the five laws of library science and suggest ways to improve it. To this end, the operation status of four national and public university libraries was analyzed with the scope of the study as the Busan area. Furthermore, for an in-depth investigation, the P University library in Busan was examined as a case. The operation status of national and public university libraries in the Busan region was analyzed by dividing them into the categories of university library collection materials, facilities, staff, material purchase costs, and users from 2018 to 2022. In particular, there was a decrease in users and a shortage of librarians due to COVID-19. In the case study, the operation status of P University library was investigated focusing on the first and fifth laws of Ranganathan's five laws of library science. In the first law, the study was conducted on the aspects of access to and use of the collection, library location, usage time and book lending, and staff. In the fifth law, the investigation was divided into service improvement aspects according to changes in digital technology of P University library and library environment improvement aspects according to changes in user characteristics. As a result of the study, 'establishment of library space composition strategy', 'establishment of blue ocean strategy', and 'expansion of recruitment and deployment of librarians' were suggested as improvement plans.
The purposes of this study are to assess iron status in mothers and their newborn infants at birth and to analyze the influence of maternal iron status on their newborn babies. Venous bloods samples were drawn from 144 pregnant women just before delivery and cord bloods of their newborn babies were collected immediately after birth for measurement of hemoglobin, hematocrit, serum iron, ferritin, total binding capacity and transferrin saturation. The values of hemoglobin and hematocrit were significantly lower in the mothers(10.9$\pm$1.43g/dl and 33.7$\pm$3.67%) than in their newborn infants(14.7$\pm$1.43g/dl and 45.3$\pm$4.76%)(p<0.0001). At delivery, serum iron levels in cord blood were about twice as high as those in the maternal blood, and serum ferritin levels in the cord blood were about four times higher than those in the maternal blood. The serum ferritin levels of multigravidas were higher than those of primigravidas,. but there was no difference between the serum ferritin levels of their infants. The serum ferritin levels of the mothers and their infants were higher in maternal group with iron supplement regularly than in other maternal group without iron supplement during pregnancy. Among the mothers, 26.4% had a serum ferritin levels below 12ng/ml(i.e. depleted iron stores)and 78.9% had a hemoglobin below 12g/dl(i.e.iron deficient anemia). When the maternal group was classified according to their serum ferritin levels by 9ng/ml, 12ng/dl or 20ng/ml, there was no significant difference in the iron status of their newborn infants among the three groups. The hemoglobin and serum ferritin levels of the mothers were well correlated with those of their babies. The maternal hemoglobin values negatively correlated with infant birth weight. It is possible that the demands of iron of the mother might be increased in the case of a newborn infant of greater size. The results of this study provide useful information regarding establishment of RDA for iron in pregnant women and guidance about the need for iron supplement during pregnancy.

Objective This study aims to understand the actual utilization of the oriental rehabilitation medicine center of the initial interdisciplinary medical care at the National Rehabilitation Center and to arrange proper development plans for more effective interdisciplinary medical services for future activation of interdisciplinary medical care. Method: The interdisciplinary patient status, composition of patient care, and major disease-related status were studied and analyzed for oriental rehabilitation medication relating to interdisciplinary medical care at the National Rehabilitation Center. Furthermore, the interdisciplinary status and its operating conditions were evaluated to devise a development plan for the National Rehabilitation Center. Results: As a result of the analysis of oriental rehabilitation medical care diagnosing status utilization at the National Rehabilitation Center regarding interdisciplinary medical care, the ratio of the number of those receiving interdisciplinary oriental rehabilitation medical care was less than half of the total receiving interdisciplinary care. As the major disease status from the patients of interdisciplinary care, stroke patients covered the large majority, and musculoskeletal pain patients covered the majority of outpatients. The establishment of additional oriental medication departments and assigning of interdisciplinary coordinators were presented as the goals of a development plan for the manpower and structural side of interdisciplinary medical care at the National Rehabilitation Center. On the institutional and systematic side, improvement in the interdisciplinary hierarchy and interdisciplinary model development based on the number of patients per disease was proposed. In addition, operation on ward bedding and construction of interdisciplinary EMR medical care is necessary on the medical and administration service side. Conclusion: To understand the actual utilization and to arrange development plans aimed at constructing a safe and effective interdisciplinary hierarchy for interdisciplinary medical care at the National Rehabilitation Center, patient-centered care needs to be implemented.
Objectives: This study aims to identify the usage status of general drugs by some college students based on their own judgment and the relevant factors having impact on them. Methods: The questionnaire survey was conducted by visiting the students in 3 colleges in Daejeon and Chungcheongnam-Do. 792 students were finally selected as the subjects. The results were statistically analyzed using the SPSSWIN(ver 13.0) and $x^2-test$, ANOVA and multiple regression analysis were conducted. Results: The usage status of college students showed the significant difference by general features, knowledge and recognition attitude. The knowledge level of students on the general drugs was very low. They had excessive expectation on the general drugs in terms of the recognition attitude. The lowest factor was the distrust on the general drugs. 27.5% of subjects was satisfied with the effect after using 48.1%m when the drugs were frequently used. Those who experienced the side effects accounted for 9.6%. In accordance with the analysis on the factors related to the knowledge on, recognition attitude on and usage status of general drugs, the education had the highest influence on the abuse and misapplication of drugs. For the mistrust factor on the drugs and negligence factor on abnormal response, the gender was the most influencing. The knowledge level was the greatest impact on the excessive expectation factor on the drugs. The factor that the usage status was the most influential was the education on the abuse and misapplication of drugs. Conclusions: The systematic approach including establishment of health policies for the improvement of health and health education activity should be implemented on the basis of the thorough analysis on the knowledge level and recognition on drugs and the factors influencing on the usage of drugs.
