이 연구는 6대 광역시에서 2009년부터 2013년까지 고시된 기록관리기준표의 대기능 항목 중 ‘문화재보존정책’을 대상으로 총 221개의 단위과제와 보존기간을 비교 분석한 후, 그 문제점과 개선방안을 제시하였다. 분석 결과 단위과제는 동일한 업무기능이 지역이나 기관별로 명확한 원칙과 기준이 없이 서로 다른 단위과제 명칭으로 사용되고, 단위과제의 실제 활용률이 낮은 것으로 나타났다. 그리고 보존기간은 단위과제에 대한 지역별 보존기간 적용 기준이 달라 보존기간이 다르게 책정되어 있다. 이에 대해 정부기능분류체계에서 준수하는 업무기능에 기반을 둔 기능분류체계와 ‘공공기록물관리에관한법률시행령’ 제26조 1항의 보존기간별 책정 기준 등의 원칙을 적용하여 개선방안을 제시하였다. This study is to drew out the way of improvement by analyzing the problems with the units and the period of conservation, after studying and comparing with overall 221 units and the period of conservation based on the policy ‘Conservation of Cultural Assets’ on the list of the function in records management criteria written from 2009 to 2013, in 6 Metropolitan cities. Then, based on the evaluation, they collected the opinions and finally presented the method of improvement. The research shows that not only the units are utilized as different names without standard or principle, but also the rate of application is very low. The period of conservation in each organization is also estimated differently, because the standards of application are not equal.

Objective: In vitro fertilization (IVF) and a prolonging the time of culture may be helpful in establishing a viable pregnancy through a selection effect. Some embryos do not develop beyond the 4-cell stage and some may not develop to the blastocyst stage. We have evaluated the safety of SET and the outcomes of pregnancy. Methods: Sperms were treated with Ham's F-10 supplemented with 10% human follicular fluid (hFF). oocytes or fertilized oocytes were cultured in Dulbecco's Modified Eagle Medium (DMEM) with 10% or 20% hFF respectively. Up to five oocytes were inseminated with approximately 200,000 sperm cells/2 ml in each well. Fertilization was examined in the following morning and fertilized oocytes were co-cultured until embryo transfer. Vero cells for co-culture were prepared in Tissue Culture Medium - 199 (TCM-199) with 10% fetal bovine serum. At the two to four cell and blastocyst on day 2 and day 5, embryo and blstocyst grading were evaluated. Pregnancy rate was determined after transfer of human embryos at the two to four cell stage on day 2 (Group I) or subsequent transfer of embryos on day 2 and at the blastocyst stage on day 5 (Group II). For statistical analysis, Student's t-test and Chi-square (${\chi}^2$_test) were used. Results were considered statistically significant when p value was less than 0.05. Results: No differences was found in the fertilization between Group I (81.0%, 98/121) and Group II (81.8%, 180/220). In case of cleavage rate, no difference was found in Group I (95.9%, 94/98) and Group II (97.8%, 174/178). However, the rate of-clinical pregnancy was significantly higher (p=0.014) in Group II (66.7%, 12/18) than in Group I (26.3%, 5/19). Conclusion: The results of this study showed that SET is safe and effective, and significantly increases the pregnancy rate.

This study was conducted to estimate how vertically high and horizontally long a sea breeze occurred around Gangneung of the Korean peninsula would be reached to an inland. Geographically, gangneung is located on the center of the east coast shaping an arc, and a coastal line around gangneung has a form extending northwestward and southeastward, respectively. Therefore, an inflow of the northerly has similar effects of the sea breeze since a deep valley of Daegwallyeong, which is one of main ridges of the Taebaek mountains, not only reaches northeastward up to this region but also plays the part of the steering gear changing a wind direction from northerly to easterly, this is, the wind from sea. First of all, the study had defined the sea breeze as a wind blown from NNE to ESE, clockwise. And then, we analyzed characteristics of the sea breeze occurred around gangneung in view of the maximum wind speed and the wind direction for October 1st, 2003 through September 30th, 2004, the upper air database for May through June of 2004, and the wind vector database of AWS (Automatic Weather System). All meteorological information is collected at the weather station of gangneung and by the AWS which is being scattered around this region. Finally, the study figures out that how horizontally long a sea breeze would be reached depends on a level of the easterly inflow. At the first step of the inflow of the sea breeze, the wind from NNW blows into this region by keeping up the speed 3 m·s-1, and effects of the northerly are dominated with time and the wind at the inland blows out southwestward cause of the surface friction at the next step. On the other hand, there is no change of wind direction in the inflow at Daegwallyeong because a surface friction of there is smaller than around gangneung, relatively. In other word, the easterly blows toward Daegwallyeong. However, the wind speed is not higher than that of the coast around gangneung.

Immobilization of spermatozoa prior to intracytoplasmic sperm injection(ICSI) sometimes results in crooked tail and this makes it difficult to aspirate sperm into an injection pipette tail first Head-first sperm aspiration into an injection pipette avoid this problem due to the bigger size of the sperm head. The effect of head or tail-first sperm injection into an oocyte on fertilization, cleavage, percentage of grade 1 embryos and development to blastocyst stage in ICSI program has been studied. A single living immobilized spermatozoa from oligoasthenozoospermic patient was injected into an oocyte head-first or tail-first according to the treatment. Eighteen hours after microinjection, oocytes were inspected for survival and fertilization Fertilized oocytes with two pronuclei were cultured in 30 μ I drop of mHTF supplemented with 10 % heat-inactivated follicular fluid(FF) at 37℃. On day 2, embryo transfer was performed with cleaved embryos. The remaining 2-8 cell stage embryos were co-cultured with BRL cells in mHTF+10 % FF for 72 hours and the developmental stage was observed. The data were analyzed by Analysis of Variance. A total of 164 oocytes from 36 cycles were assigned to each treatment and ICSI was performed(88 head-first, 76 tail-first). The rates of normal fertilization were 81.8 % and 76.3% for head-first and tail-first, respectively. Of the fertilized oocytes, the percentage of cleaved embryos and the percentage of grade 1 embryo among cleaved embryos were 88.9 % and 68.8 %, 93.1 % and 74.1 % for head-first and tail-first, respectively. Of the 2-8 cell embryos cultured, 44.4 %(16/36) and 50.0%(10/20) for head first and tail first, respectively developed to blastocyst stage. There were no differences in fertilization, cleavage, rates of grade 1 embryos, and development to blastocyst stage. In conclusion, head-first or tail-first sperm injection into an oocyte in ICSI program does not affect fertilization and subsequent embryo development to blastocyst stage in vitro.
