It is utmostly important to establish the efficient fitable way of peoples' active participation in primary health care especially in the areas where the public or governmental service input for the basic health care is insufficient like as in rural areas of Korea. In light of above reason, this study focused mainly on the evaluation of roles and activities of village health workers (VHWs) who were selected from grass- root level of village people in order to derive further motivation for active participation. This is believed to be a sort of feedback mechanisms. Actually, the authors collected the activity reports of VHWs who had been devoting themselves in the primary health care services of Jeomdong Area, of Yeoju Gun one of Korea University Community Health Action Programmes and survey record on the VHWs activity from correspondent people. 1 hose data were analyzed through computer programmed package. The activities performed by VHWs were limited to the performance in 1985 for conveniance. The summarized results were as follows; 1) General characteristics of VHWs. Among a total of 28 VHWs in the area, about 39.3g of them have been replaced up to the date since the implementation in 1983, because of moving out, occupational employment and of others. The age of majority (75.0%) lied between the range of 30-50, and educational background of 67.9% belonged to category of primary school graduation, about 50% of them experienced to be or were also entiled "chief of women club" of corresponding villages. 2) Work-load of VHWs. Each VHW was assigned for tasks of health care for average 55 households of 248 persons. They shared approximately 6 days a month for the activity in average and it covered 17 cases of basic health care in a month. A half of the VHWs performed home visits irregularly without solidified schedule. 3) Work performance analysis. Informations collected through VHWs were compared with data from official vital registration at local administration center "Myon Office" in 1985. VHWs collected 100.8 of new born, 116.2 of death, 58.3 of move in and 74.8 of move out in comparison with 100.0 of official registration each. Pregnant women of 79.8% of mothers among the total pregnancy of 94 which were confirmed as normally delivered or aborted cases by all means afterwards had been detected by VHWs as being pregnant and all of them received some of antenatal cares by VHWs. All(100%) of delivered women were detected by VHWs through home visits and they were cared postnatally. Whereas, according to the records of birth registration, the places of delivery were clinic in 33.7%, and mother's home in 66.3%, VHWs reported them to be clinic in 48.9%, midwifery in 20.2%. It was cleared that most of misinformation was caused by uncautious filling of birth registration at notification. Among the total of 717 eligible women under age 44 years, family planning status of 92.6% was reported by VHWs confirming practice of control to be 70.8% of reported fertile women. 4) Attitude of VHW on the roles and functions. Although 92.0% of VHWs expressed VHWs to be worthwhile, only 52.0% of them had dignity and satisfaction in their activity and 44.0% of them had passive attitude of working saying they followed direction regardlessly. Concerning difficulties in performance as a VHW, 60.7% of them pointed out lacking of medical and health related knowledge by themselves. Still, 64.0% of them thought visiting unfamilier house to be awful and 40.0% complained forms of activity to be difficult and hard. It was also revealed that 56.6% confessed lack of interest on community health service itself. Most of VHWs needed more educational training especially on clinical fields such as cares of gynecological diseases, hypertension, diabetes, and other chronic diseaes of the aged. Regular on-the-job basic trainings were said to be needed twice a year.

Kojedo is the second largest island in Korea and a total population of 115,500 is living on the island of 394.69 sq. km. Under the direction of three nutrition professors, nutrition surveys in two villages in Kojedo, namely Siljun Ri in Hachung Myon and Soowol Ri in Shinhyun Myon, were carried by 30 college senior students majoring in nutrition from August to 20 August 1977. From a total of 176 households of the two villages, 67 households were randomly selected and 390 family members of the households were subjcets of the nutrition surveys. The precise weighing method was used in evaluating the kinds of foods and nutrient intakes of the subjects for three consecutive days. Thirty-seven pre-school children aged between 3 to 6 years and 27 fertile women were examined for biochemical findings and physical status. The main purposes of the surveys are to provide baseline data on nutrition in Kojedo Island for the Kojedo Community Development Project and to compare the nutritional status of the villages of Siljun Ri and Soowol Ri. Siljun Ri is located in the pilot project area of the Koiedo Community Health Project sponsored since December 1970 by the Christian Medical Commission of the World Council of Churches. While Soowol Ri is a control village for comparison. The results obtained are summarized as follows: Food Intake The average food intake per person per day in Siljun Ri, 1064 grams (91.7% in vegetable foods and 7.6% in animal foods) was 90 grams more than that of Soowol Ri, 974 grams (92.8% in vegetable foods and 5.9% in animal foods). However, the food intake per pre-school child in Siljun Ri, 485 grams (92.6% from vegetable foods and 6.4% from animal foods) was 21 grams lower than that of the Soowol Ri, 506 grams (88.5% from vegetable foods and 6.5% from animal foods). The average intake of beans was 16 grams(1.5% out of the total food intake) in Siljun Ri and 21 grams(2.2% of the total food intake)in Soowol Ri. The villagers should be guided for more consumption of soybeans to improve the quality of protein intake from vegetable foods. Nutrient Intake The adult intake in Siljun Ri and Soowol Ri were 2,529 kcal and 2,511 kcal respectively. The average energy intake of pre-school childen in Siljun Ri was 948 kcal and that for adult and 1,500 kcal for childen aged between 4 to 6 years-given by the Korea FAO Association, the diets in both villages were not adequate. Average daily protein intake of the subjected adult in Siljun Ri was 78.4 grams and that of Soowol Ri was 76.2 grams, while pre-school children took 30.7 grams in the former village and 31.7 grams in the latter village per child per day. The protein intake in both villages were lower than the recommended allowances, 80 grams for adult and 45 grams for $4{\sim}6$ years childen, and animal protein intake of the all subjects was very much lower than the RDA. The main charecter of the diet has been found low in quality of protein and high in carbohydrate. The calcium intakes of the pre-school children in both villages, 251.9 milligrams in Siljun Ri and 218.8 milligrams in Soowol Ri, were very much lower than the recommended allowance of 500 milligrams per day. It is apparent that the diet for children should be supplemented with calcium. Among the vitamin group, the daily average intakes of vitamin A and $B_{2}$(thiamine), $B_{2}$(riboflavin), C(ascorbic acid), and niacin were not adequate for the children in both villages. Especially the intake of riboflavin, 0.4 milligrams in both village children, was much lower than the RDA, 0.9 milligrams per day. Physical Characteristics Average height, weight, chest and head circumference of the pre-school children in both villages were similar to those of the Korean standard given by the Korean Paediatrics Association except that the average height of pre-school boys in Siljun Ri was 8 cm higher than the Korean standard of 105 cm. The mean values of upper arm circumference and skinfold thickness of pre-school boys in both villages were the same, 15.4 cm for upper arm circumference and 6.8 mm for skinfold thickness, but the mean values of those of the girls in Siljun Ri were higher than those of pre-school grils in Soowol Ri. Biochemical Findings Avera ge hemogobin value of boys and girls in both villages was the same, 11.1 grams per 100 ml of blood. The incidence of anemia (Hb value below 11g/100ml) was similar in both viltagesr 36.4% for boys and 50% for girls in Siljun Ri and 37.5% for boys and 50% for girls in Soowol Ri. Average hemoglobin values of fertile women were 10.7g% in Siljun Ri and 10.8% in Soowor Ri. The incidences of anemia(Hb valre brlow 12g/100ml) were 100% in Siljun Ri and 86.7% in Soowol Ri. The anemia of these subjects may be caused mainty low intake of good quality protein and iron intake from vegetable food. Recommendation In general, the nutritional status of a community health pilot village is not higher than that of control village due to the lack of nutrition improvement guldance services. Nutrition education should be delivered to the villagers as a main part of the health education artivities. The emphasis should be on building better health through bttter food habits and better food production as well as on preventing malnutrition and diseasrs. It can be an invaluable part of community developnent. Since nutrition is considered to be at least one-half of MCH care, no village or home visits should be made without careful provision for teaching and demoastrating something simple and practical on nutrition. The nurse, midwife, and village health worker should be the chief promoters of nutrition.

Objective : Previous studies have suggested that hyperhomocysteinemia and methylenetetrahydrofolate reductase (MTHFR C677T) mutations are associated with increased risk of recurrent spontaneous abortion (RSA). Recently, a second site polymorphism in MTHFR, 1298A-->C, which changes a glutamic acid into an alanine residue, was shown to be associated with a decreased enzyme activity. We tested whether the variant alleles of MTHFR C677T and A1298C are risk factor (biomarker) for RSA. Materials and Methods: We analyzed DNA from a case-control study in the Korean DNA was extracted from blood samples of 118 patients with RSA and 123 healthy fertile patients as the controls. MTHFR variant alleles were determined by a PCR-restriction fragment length polymorphism assay. Results: We found no evidence for an association between 677TT genotype and risk of RSA (OR=1.95, 95% CI=$0.84{\sim}4.50$, p=0.12). However, the MTHFR 1298AC (OR=0.36, 95% CI=$0.20{\sim}0.63$, p=0.0004) and 1298AC+CC (OR=0.35, 95% CI=$0.20{\sim}0.61$, p=0.0002) genotypes were lower among 118 RSA cases compared with 123 controls, conferring a 2.8-fold decrease in risk of RSA, respectively. Moreover, the combined genotypes of MTHFR 677CC/1298AC (OR=0.30, 95% CI=$0.10{\sim}0.88$, p=0.029) and 677CT/1298AC (OR=0.77, 95% CI=$0.60{\sim}0.99$, p=0.043) also showed significantly lower risk than those with MTHFR 677CC/1298AA type. Conclusion: MTHFR 1298AC, MTHFR 677CC/1298AC and 677CT/1298AC genotypes may represent genetic markers for the protection of RSA at least in Korean women.

The early studies demonstrated that the relative amount of FSH was important for stimulating normal ovarian activity and demonstrated the existence of a threshold level for FSH, above which follicular growth was activated. It was found that only a modest increase in circulating FSH level above the threshold (between 10 and 30%) was required to stimulate folliculogenesis. In addition, FSH is primary responsible for initiating estradiol production through the activation of the aromatase enzyme system in granulosa cells, follicular secretion and growth. LH on the other hand, plays a supportive role in ovarian steroidogenesis, stimulating the ovarian thecal cells to produce androgen, the precursor for estradiol synthesis. But there is now an increasing number of reports in the literature demonstrating an adverse effect of LH on fertility and miscarriage in infertile and fertile women. So HP-FSH is the drug of a highly purified FSH preparation which has a higher specific activity and far fewer impurities than FSH. This study was performed to evaluate the efficacy and safety of HP-FSH administered (SC; subcutaneous) versus FSH(IM; intramuscular) for ovulation induction. 20 candidates patients for ovulation induction were participated. All patients underwent pituitary desensitizing with a long gonadotropin-releasing hormone (GnRH) agonist protocol and ovulation induction was started with HP-FSH SC (10 patients; group I) or FSH IM (10 patients; group II). After ovulation, outcome of ovulation induction and local reaction of injection site were compared. There were no difference of outcome of ovulation in two groups except pregnancy rate/embryo transfer. Group I had a higher pregnancy rate/ embryo transfer than Group II (44.4% Vs 28.6%). Pain, redness, tenderness, bruising and itching when the injection received on the first 5 days of treated (50 SC and 50 IM injections) were assessed. There were no significant difference (P>0.05) in the incidence of tenderness, bruising and itching between the IM and SC injection. But IM injection (FSH) had a tendency of higher above incidence. The number of reports of pain, redness were significantly increased in IM injection group (P<0.05). These results indicate that SC administration of HP-FSH has been shown to be as effect for superovulation as traditional gonadotropins, with an improved safety profile due to the removal of extaneous proteins.

Mammalian oviductal epithelial cells have been known to improve in vitro fertilization and embryonic development. Recently, co-cultured human embryos with the epithelial cells in human genital tract has been reported to improve the pregnancy rate. The purpose of the study was to investigate the effects of the epithelial cells of human genital tract on the development of mouse early embryos and human fertilized oocytes. The epithelial cells of human genital tract were collected from the fallopian tubes which were obtained during hysterectomy in fertile women and from the endometrium during endometrium biopsy. Collected human ampullary cells(HACs) and endometrial cells(HECs) were cultured for 10 days to establish primary monolayer. Second passaged HACs and HECs were obtained by trypsinization were cryopreserved in PBS with 1.5 M DMSO for later use. To investigate the effect when co-cultured with HACs and HECs, we tried to apply strict quality control on mouse embryo, from two cell to blastocyst prior to human trial. The results of quality control were as follows; In Group I (Ham's F10 with 10% FCS), Group IT (co-cultured with HACs) and Group ill (co-cultured with HECs), developmental rates to blastocyst were 63.3%(253/400), 76.0%(304/ 400),74.0%(296/400), respectively. Hatching rates were 36.8%(147/400), 41.80/0(167/400), 38.0%(152/400), respectively(p<0.05). To perform the human IVF, cryopreserved HACs were thawed at 37$^{\circ}C$ waterbath, seeded on the well dish and cultured for 48 hI'S. The pronuclear stage embryos were transferred to the seeded well dish. After 24 hRS, co-cultured embryos were examined and transferred to patient's uterus. The results of human IVF when co-cultured with HACs were that fertilization and developmental rates were 61.8% (256/414), 95.3% (244/256) as compared with 57.2% (279/488) and 94.6%(264/279) in Ham's F10 supplemented with 10% FCS(control). However, 62.9% (161/256) of co-cultured human embryos showed good embryos(no or slight fragmentation) as compared with 53.8 % (150/279) in control(p < 0.05). Pregnancy rate was 40.0% (12/30) when co-cultured with HACs whereas 30.6%(11/36) in control. In conclusions, co-culture system using HACs and HECs improved the developmental and hatching rates of mouse embryo. Also, in human IVF system when co-cultured with HACs, it improved both the quality of human embryos and the pregnancy rate.

복부-골반 CT검사 시 피폭선량을 측정해 보고, 영상 판독에 영향을 미치지 않는 범위에서 복부와 골반의 피폭선량 최적화를 위한 프로토콜을 제시하고자 하였다. 기존 임상의 스캔 방식인 120 kVp, AEC(auto exposure control) 기법을 이용한 복부-골반을 1 phase로 스캔을 하였고, 새로 제시한 2 phase 스캔 방식은 1 phase 복부검사와 2 phase 골반검사로 각각 나누어 복부검사는 관전압 120 kVp, AEC, 골반검사는 120 kVp, 100, 150, 200, 250, 300, 350, 400 mA로 고정 관전류 기법을 이용하여 실시하였다. 스캔 시 측정된 $CTDI_{VOL}$, DLP 값을 이용해 선량값을 비교하였고, 각 스캔 영상에서 CT 감약계수와 노이즈, SNR의 평균값을 구해 영상을 평가하였다. 연구결과는 2 phase 스캔 시 1 phase 스캔 시보다 $CTDI_{VOL}$ 값은 복부에서 26%, 골반 100~250 mA에서 1.8~59.5% 감소, 300~400 mA에서 12.7~30% 증가로 유의한 차이를 보였다. 또한, DLP값은 2 phase 스캔 시 1 phase 스캔 시보다 복부에서 약 53%, 골반에서 약 41~81% 감소를 보였으나 통계적으로 유의하지 않았다. SNR은 심장주변에서 2 phase 스캔 시, 골반주변에서는 1 phase 스캔 시, 상복부와 하복부에서 1 phase 스캔 시보다 2 phase 200~250 mA 스캔 시 높게 나타났다. 또한, CT Number와 노이즈는 전반적으로 비슷한 양상을 보였지만, 골반 주변에서 노이즈가 높게 나타났다. 그러나 2 phase의 골반주변 250 mA 스캔 시 1 phase와 비슷한 노이즈값을 나타냈고 통계적으로 유의한 차이를 보이지 않았기에 통상적인 1 phase 400 mA보다 골반을 분리시켜 250 mA 스캔 시 화질에 차이 없이 피폭선량 감소효과를 볼 수 있을 것으로 본다. 그러므로 잦은 복부-골반 CT를 시행하는 환자 혹은 가임기여성, 소아의 골반은 피폭을 줄이면서 화질차이 없이 검사를 위한 2 phase 검사를 제안한다.

착상은 배아측과 모체측의 내분비적, 측분비적 및 자가분비적 인자들의 상호 작용에 의하여 조절된다. 착상의 적기는 $2{\sim}4$일로서 이 특수한 시간대 안에서 signaling, appositioning, attachment 및 invasion을 통하여 순차적으로 배아의 착상이 이루어지는데, 이는 자궁내막과 배아로부터 여러 사이토카인, 성장인자, 부착인자와 같은 다수의 생화학 인자의 생성과 분비를 포함하며 이로 인하여 수용적인 자궁내막이 형성된다. LIF, CSF-1, IL-1과 같은 사이토카인들은 착상을 이끄는 연속적인 사건에서 중요한 역할을 수행하며 integrin, L-selectin ligands, glycodelin, mucin-1, HB-EGF, pinopodes는 appositioning과 attachment에 관여한다. 배아 또한 사이토카인과 성장인자 및 LIF, CSF-1, IGF, HB-EGF에 대한 수용체들을 분비하여 능동적으로 대처한다. 자궁내막의 수용성을 평가하고 자연주기 또는 보조생식술을 이용한 임신의 예후를 예측하는데, 이와 같은 인자들이 유용한지는 앞으로 더 연구되어야 한다. 현재로서는 내막조직으로부터 채취한 integrins, pinopodes, glycodelin, LIF가, 자궁강내 세척액에서는 glycodelin과 LIF가 유망한 인자로 떠오르고 있다. 혈액내 마커로서는 VEGF, glycodelin, CSF가 약간의 연관성을 보여주고 있다. 이러한 인자들이 보조생식술 전후로 자궁내막의 기능과 임신의 예후를 평가하는 선별검사로 이용될 수 있는지를 증명하기 위해서는 향후 불임 여성과 대조군인 가임 여성을 대상으로 한 대규모의 연구가 필요할 것이다. 인간의 착상에서 이들 인자들의 기능을 충분히 이해해야 치료적 기법으로 연결되어 보조생식술에서도 더 높은 성공률을 이루어 낼 것으로 사료된다.
