  • Feed intake (FI) of sows during lactation is a serious problem because sows require a large amount of energy for high milk production during lactation. Providing a palatable diet is important for lactating sows to cope with the stress of breast-feeding. Palatability can be increased by adding sweeteners to diets. This study was conducted to evaluate the effects of saccharin (sweetener) on growth performance, fecal moisture, and litter performance of lactating sows. Sixteen sows were randomly allotted to one of two dietary treatments in a 27-day trial starting from lactation. The two dietary treatments were supplemented with 0 and 0.2% saccharin (sweetener), respectively. Average daily feed intake (ADFI) was increased (p < 0.05) and back fat loss (BFL) was decreased (p < 0.05) in sows fed saccharin supplementation diets compared with sows fed control diet during lactation. However, sows' body weight loss, body condition score (BCS), fecal score, and the number of piglet survival were not different (p > 0.05) among dietary treatments. The two dietary treatments also had no significantly different effect (p > 0.05) on litter weight and average daily gain (ADG) of piglets. Taken together, saccharin has no significant effect on growth performance of piglets but it can increase FI and reduce BFL of lactating sows.

  • A total of 112 crossbred pigs [(Yorkshire ${\times}$ Landrace) ${\times}$ Duroc] with an average body weight (BW) of $27.98{\pm}1.28kg$ were used to evaluate the effects of replacing soybean meal (SBM) with rapeseed meal (RSM) as a source of protein on growth performance, nutrient digestibility, blood characteristics, and fecal noxious gas emission in growing pigs. The pigs were blocked and stratified based on BW into one of four dietary treatments in a 6-week trial. Each treatment consisted of 7 replicate pens with 4 pigs per pen (2 barrows and 2 gilts). Treatments were 1) maize-SBM based diet, 2) diet containing 2% RSM, 3) diet containing 4% RSM, and 4) diet containing 6% RSM. Supplementation with RSM resulted in no differences in growth performance, nutrient digestibility, and noxious gas emission, as compared with SBM supplementation during the experimental period (p > 0.05). Pigs fed with increased dietary RSM (0, 2, 4, and 6% of feed) had linear decreases in average daily gain (ADG) (p = 0.010) and nitrogen digestibility (p = 0.036) and a linear increase in blood creatinine concentration. In conclusion, RSM fed pigs had no detrimental effects on their growth performance, nutrient digestibility, blood characteristics, and fecal noxious gas emissions, as compared with SBM fed pigs. Thus, RSM is a good alternative to SBM as a protein source in growing pigs' diets.

  • This paper studied the present condition of social welfare activities of Living Condition Improving Committee of Kimpo City in order to activate the social welfare services of women agricultural organizations. The main results are as follows; First, the general characteristics of the respondents in this study are forty or fifty years of age with above high school education with main income source of agriculture and middle class women living in agricultural communities more than 10 years. Second, considering the present and future planned activities of the Living Condition Improving Committee of Kimpo City this study finds that there is high expectation of helping poor people and joining voluntary services. Third, the members of the Living Condition Improving Committee of Kimpo City have actively participated in the local welfare service programs however, there is significant difference among people according to the age, living standard and joining period. Fourth, out of social welfare activities managed by the Living Condition Improving Committee of Kimpo City the welfare service activities for old people and local community are most active and the participants in the welfare service activities for women and the youngsters are small. Thus, according to this study the Living Condition Improving Committee of Kimpo City should consider the following three points in order to activate the social welfare service activities; First, as the members are expecting to expand the individual activities and to enhance the private improvement, the social welfare service activities should meet with the demands to improve self satisfaction of the participants. Second, new programs should be developed after reviewing the current programs in order to meet with the need of the members. Third, as the committee has not established a network system with government administrative organizations and relating institutions, and as its activities are concentrated in particular areas the committee should establish a new system to provide more efficient services in line with the cooperation with public organization and welfare resource suppliers.

  • Fermented Rhus verniciflua (FRV) as feed additives act as excellent anti-diarrheal drugs as they increase the intestinal absorption rate therefore being indirectly associated with enhancing growth performance and increasing digestibility in livestock. A total of 80 weaned pigs with an average initial body weight (BW) of $6.82{\pm}1.11kg$ were used to evaluate a diet supplemented with FRV meal in a 6 week feeding trial with two dietary treatments [CON - basal diet; TRT - CON + 0.2% FRV] on growth performance, apparent total tract digestibility (ATTD), blood profiles, fecal microflora, and fecal score. Our results showed that the dietary supplementation of FRV improved (p < 0.05) average daily gain and gain : feed (G : F) ratio during days 15 - 42 and the overall experiment period and also increased the ATTD of dry matter (p < 0.05) at days 14 and 42. On the contrary, there was no effect (p > 0.05) on average daily feed intake, ATTD of nitrogen and energy, and blood profiles during the entire experiment. Moreover, dietary inclusion of FRV significantly increased fecal Lactobacillus (p < 0.05) counts and reduced the diarrhea during days 22 - 42. Thus, the results suggest that FRV can be used as a potential additive to improve growth performance and dry matter and to reduce diarrhea while having beneficial effects on fecal microflora in weanling pigs.

  • Objectives: The Yongpung reservoir in Korea is a crucial facility that supplies water to farms in its surrounding $2km^2$ area. However, its water quality is not suited to the needs of current residents who wish for the availability of environmentally friendly agricultural products and desire to use the waterfront area. The aim of this research was to evaluate the reservoir's fish and benthic macroinvertebrate distributions and determine its water quality and the heavy metal content in its sediment. This basic data can be used to establish environmentally protective plans for the Yongpung reservoir. Methods: Six sites were selected for analysis in this investigation. Three points (YP-1, YP-2, and YP-3) were evaluated for water quality and metal content in sediments; they were located upstream, midstream, and downstream of the reservoir. Samplings of the fish and benthic macroinvertebrate populations were performed at three other sites: St. 1, St. 2, and St. 3. Results: Based on chemical oxygen demand (COD) and total nitrogen (T-N) data, the quality of the Yongpung reservoir water corresponds to Class VI (very poor) according to Korea's lake environmental standards. The lead levels measured in the sediment at the midstream and downstream points of the reservoir were 76.7 and 72.7 mg/kg, respectively, while 8 orders, 15 families, and 16 species of benthic macroinvertebrates were identified in the reservoir. The ecological score of the benthic macroinvertebrate community (ESB) was between 8 and 23, denoting poor to very poor environmental conditions. Further, 4 families and 7 species of fish were identified in the reservoir, with Cyprinidae accounting for 94.3% of all observed freshwater fish. Conclusion: Based on these findings, we conclude that management plans, including the removal of lead from the sediment, are necessary to improve the quality of the agricultural water in this reservoir. The T. japonica, which cover almost 30% of the water area, must also be removed.

  • Recently concerns have been raised due to the unbalanced supply of crops: the price of crops has been unstable and at one point the price went up so high that the word Agflation(agriculture+ inflation) was coined. Korea, in particular, is a small-sized country and needs to secure the stable supply of crops by investing in the produce importation at a national level. Investment in foreign produce importation is becoming more important as a measure for sufficient supply of crops, limited supply of domestic crops, weakened farming conditions worldwide, as well as recent changes in the use of crops due to the development of bio-fuels, influence of carbon emission on crops, the price increase in crops, and influx of foreign hot money. However, there are many problems with investing in foreign produce importation: lack of support from the government; lack of farming information and technology; difficulty in securing the capital; no immediate pay-off from the investment and insufficient management. Although foreign produce is originally more price-competitive than domestic produce, it loses its competiveness in the process of importation (due to high tariffs) and poor distribution system, which makes it difficult to sell in Korea. Therefore, investment in foreign produce importation is being questioned for feasibility; to make it possible, foreign produce must maintain the price-competitiveness. Especially, harvest of agricultural products depends on natural and geographical conditions of each country and those products have indigenous properties, so distribution system according to import and export of agricultural products should be treated more carefully than that of other industries. Distribution costs are differentiated into each item and include cost of sorting and wrapping, cost of wrapping materials, cost of domestic transport, cost of international transport and cost of clearing customs for import and export. So transporting and storing agricultural products generates considerable costs compared with other products. Also, due to upgrade of dietary life, needs for stability, taste and visible quality toward food including agricultural products are being raised and wrong way of storage causes decomposition of food and loss of freshness, making the storage more difficult than that in room temperature, so storage and transport in distribution of agricultural products needs specialty. In addition, because lack of specialty in distribution and circulation such as storage and wrapping does not solve limit factors in distance, the distribution and circulation has been limited to a form of import and export within short-distant region. Therefore, need for distribution out-sourcing which can satisfy specialty in managing distribution and circulation and it is needed to establish more effective distribution system. However, existing distribution system of agricultural products is exposed to various problems including problems in distribution channel, making distribution and strategy for distribution and those problems are as follows. First, in case of investment in overseas agricultural industry, stable supply of the products is difficult because areas of production are dispersed widely and influenced by outer factors due to including overseas distribution channels. Also, at the aspect of quality, standardization of products is difficult, distribution system is quite complicated and unreasonable due to long distribution channels according to international trade and financial and institutional support is not enough. Especially, there are quite a lot of ineffective factors including multi level distribution process, dramatic gap between production cost and customer's cost, lack of physical distribution facilities and difficulties in storage and transport due to lack of wrapping containers. Besides, because import and export of agricultural products has been manages under the company's own distribution according to transaction contract between manufacturers and exporting company, efficiency is low due to excessive investment in fixed costs and lack of specialty in dealing with agricultural products causes fall of value of products, showing the limit to lose price-competitiveness. Especially, because lack of specialty in distribution and circulation such as storage and wrapping does not solve limit factors in distance, the distribution and circulation has been limited to a form of import and export within short-distant region. Therefore, need for distribution out-sourcing which can satisfy specialty in managing distribution and circulation and it is needed to establish more effective distribution system. Second, among tangible and intangible services which promote the efficiency of the whole distribution, a function building distribution environment which includes distribution information, system for standard and inspection, distribution finance, system for diversification of risks, education and training, distribution administration and tax system is wanted. In general, such a function building distribution environment is difficult to be changed and supplement innovatively because its effect compared with investment does not appear immediately despite of its necessity. Especially, in case of distribution of agricultural products, as a function of collecting and distributing is performed individually through various channels, the importance of distribution information and standardization is getting more focus due to the problem of repetition of work and lack of specialty. Also, efficient management of distribution is quite difficult due to lack of professionals in distribution, so support to professional education is needed. Third, though effort to keep self-sufficiency ratio of staple food, rice is regarded as important at the government level, level of dependency on overseas of others crops is high. Therefore, plan for stable securing food resources aside from staple food is also necessary. Especially, governmental organizations of agricultural products distribution in Korea are production-centered and have unreasonable structure whose function at the aspect of distribution and consumption is quite insufficient. And development of new distribution channels which can deal with changes in distribution environment and they do not achieve actual results of strategy for distribution due to non-positive strategy for price distribution. That is, it implies the possibility that base for supply will become vulnerable because it does not mediate appropriate interests on total distribution channels such as manufacturers, wholesale dealers and vendors by emphasizing consumer protection excessively in the distribution of agricultural products. Therefore, this study examined fundamental concept and actual situation for our investment to overseas agriculture, drew necessities, considerations, problems, etc. of overseas agricultural investment and suggested improvements at the level of distribution for price competitiveness of agricultural products cultivated in overseas under five aspects; government's indirect support, distribution's modernization and distribution information function's strengthening, government's political support for distribution facility, transportation route, load and unloading works' improvement, price competitiveness' securing, professional manpower's cultivation by education and training, etc. Here are some suggestions for foreign produce importation. First, the government should conduct a survey on the current distribution channels and analyze the situation to establish a measure for long-term development plans. By providing each agricultural area with a guideline for planning appropriate production of crops, the government can help farmers be ready for importation, and prevent them from producing same crops all at the same time. Government can sign an MOU with the foreign government and promote the importation so that the development of agricultural resources can be stable and steady. Second, the government can establish a strategy for an effective distribution system by providing farmers and agriculture-related workers with the distribution information such as price, production, demand, market structure and location, feature of each crop, and etc. In order for such distribution system to become feasible, the government needs to reconstruct the current distribution system, designate a public organization for providing distribution information and set the criteria for level of produce quality, trade units, and package units. Third, the government should provide financial support and a policy to seek an efficient distribution channel for foreign produce to be delivered fresh: the government should expand distribution facilities (for selecting, packaging, storing, and processing) and transportation vehicles while modernizing old facilities. There should be another policy to improve the efficiency of unloading, and to lower the cost of distribution. Fourth, it is necessary to enact a new law covering exceptional cases for importing produce in order to maintain the price competitiveness; currently the high tariffs is keeping the imported produce from being distributed domestically. However, the new adjustment should be made carefully within the WTO regulations since it can create a problem from giving preferential tariffs. The government can also simplify the distribution channels in order to reduce the cost in the distribution process. Fifth, the government should educate distributors to raise the efficiency and to modernize the distribution system. It is necessary to develop human resources by educating people regarding the foreign agricultural environment, the produce quality, management skills, and by introducing some successful cases in advanced countries.

  • The maternal and child health is a basis of national health, and indicates the level of social welfare and health of the country, because it is related with community welfare status, general cultural conditions, and medical and health sciences. This is a study carried out to identify the present practices of maternal and child health care programs implemented by the private clinics located in Guns(counties ; rural area) in Kyungsangnam Province and to propose alternatives to improve their current programs through a self-administrative questionnaire. The subjects were 90 private physicians who operated their own clinics since 1990 and were general practitioners, Obstertrician/Gynecologists or pediatricians: This survey was conducted by mail from 15 January to 25 February 1992. The response rate was 94.4 percent. 1) The major manpower for MCH programs of the studied clinics was physicians and nurseaids. 70.3% of physicians were general practitioners, 81.1% of nursing manpower were nurseaids. 31.1% of the studied clinics employed lab-technicians. 89.2% of them had MCH room whatever the size and the setting, and 84.4% of Ob/Gyn clinics installed laboratory equipments. 2) 55.4% and 63.5% of the studied clinics provided 151 or above consulting services and curative services of MCH per physician a month respectively and 33.8% and 25.7% of them provided 10 or less consulting services and curative services per physician a month. 91.9% of lab-technicians had 10 or less laboratory tests per technician a month. 3) There was a difference between Ob/Gyn and pediatric clinics in terms of services delivered : for example, 80% of Ob/Gyn clinics provided pre- and post- natal care services, while 84.6% of pediatric clinics provided vaccinations for children. It was also found that only a few of general practitioners involved pre-and post- natal care services. 4) There were no clinics which had opened regular health education session but 24.3% of them had opened the sessions irregularly. Ob/Gyn clinics put emphasis on maternity and pediatric clinics did on child health, but general practitioners touched with both maternal and child health. 21.6% of the studied clinics had some kind of educational materials for MCH programs. Most of the materials were pamphlets or small booklets. 5) Proteinuria/glucosuria, blood pressure and blood type were tested in 48.6~69% of the studied clinics ; tests for blood sugar and hepatitis B were provided in 39.2~41.9% of them, most of them were done in Ob/Gyn clinics. 6) 41.9% of physicians, 29.7% of nurses and 45.9% of nurses-aids wanted to receive on-job-training for MCH programs.

  • A survey of the notion and intake on Kimchi among college women in Pusan was conducted to get some basic information on kimchi. Two hundred sixty seven students in Pusan participated in this survey. Seventy five percent of students answered that they like kimchi. They preferred well-fermented kimchi with anchovy extracts, refreshing taste and crispy texture the saltly and sweet. Chinese cabbage kimchi (87.6%) was found to be the most favored kimchi and Kakdugi(seasoned pickles of cubed radish), Nabak kimchi and Chonggak kimchi (ponytail kimchi) were followed in the order. The most favorite food made from kimchi was stir fried kimchi with rice. They disliked traditional special kimchi, such as Puchu kimchi (leek kimchi), Pa kimchi (green onion kimchi), Kkennip kimchi (perilla leaf kimchi), Godulbaegi kimch (Korea wild lettuce kimchi) and Gat kimchi (Leaf mustard kimchi). About 93 grams of kimchi was consumed daily and this amount was a little. Seventy percent of students did not have any experiences preparing kimchi. Experiences of kimchi preparation were given by mother through kimchii-making event for the winter(71.7%), cooking practice in middle or high school (14.1%) and college(10.9%) and general cooking education (33%). They preferred to buy kimchi at the Agricultural Cooperative Association (48.5%) or a large kimch factory (32.75). College students believe that kimchi is a healthy food and are willing to learn how to make kimchi.

  • Glycosaminoglycans (GAGs) were isolated from the porcine testis, and their immuno-modulating and anticoagulant activity was investigated. From anion exchange chromatography (Dowex Macropolous Resin) used for further isolation of porcine testis GAGs (PT-GAGs), two fractions (PT-GAG-1.5 and PT-GAG-16) eluted by different salt concentration were obtained. In immunomodulating activity test, PT-GAG-1.5, but not PT-GAG-16, significantly enhanced the growth of murine peritoneal macrophages. In addition, treatment with PT-GAG-1.5 induced the production of cytokines, interleukin-1$\beta$ (IL-1$\beta$), interferon-${\gamma}$ (IFN-${\gamma}$) and tumor necrosis factor-$\alpha$ (TNF-$\alpha$), from murine microphages. Unexpectedly, both of PT-GAGs had no effect on the growth of murine splenocytes. The anticoagulant activity of PT-GAG-1.5 and PT-GAG-16 was examined by activated partial thromboplastin time (aPTT) assay and thrombin time (TT) assay. Both of PT-kGAGs significantly increased the clotting times of aPTT and TT in a dose-dependent manner. The anticoagulant activity of PT-GAG-16 was found to be higher than that of PT-GAG-1.5. These results suggest that PT-GAGs possess biological activities such as immunomodulating activity and anticoagulant activity.
