This study was conducted to examine the effect of HACCP implementation on the cost of medicine use, antibiotic utilization,and productivity of swine in Korea. Data were collected from forty-five swine farms before and after implementation of a HACCP system. The cost of medicine used, the number of different antibiotics used and the number of feeds containing antibiotic supplements added at the feed company tended to be lower (p>0.05) after HACCP implementation. Additionally,the number of feeds containing antibiotics supplemented at the farm was significantly lower after HACCP implementation (p<0.05). Moreover, the number of piglets born per sow per year and pigs marketed per sow per year were higher after HACCP implementation (22.0, 20.0) than before HACCP implementation (20.4, 18.9). These results suggest that implementation of HACCP systems on swine farms may provide beneficial effects such as reduction of medical expenses and improved productivity, as well as increased safety of livestock products for consumers.

The purpose of this study is to analyze the current status of Dokdo-ri's publicly announced land price and suggest alternatives to strengthen the effective control of Dokdo-ri, which is the result of state influence exercise. The analysis method is a technical analysis method to check the status of changes in the publicly announced land price, and analyze it in terms of the public announcement law for Dokdo-ri publicly announced land price, the cadastral system, and the plan to realize the publicly announced land price. Previous research on the actual status of Dokdo-ri publicly announced land price, and data from the Ministry of Land, Infrastructure and Transport and Ulleung County Office publicly announced land price. The temporal scope of the study is limited to the period from 2012 to 2023 as an extension of the previous study, Professor Beom-kwan Lee's presentation of ‘Study on the Characteristics of Dokdo-ri Official Land Prices’. Result of the analysis, first, the purpose of calculating the publicly announced land price of Dokdo from 2000 to 2022 included the purpose of strengthening sovereignty, which resulted in a steady increase in land prices. Second, in accordance with the Spatial Information Management Act, the instrumental law that requires publicly announced land prices as an essential item in cadastral studies was used as a means to strengthen the effective control of Dokdo. Third, the simple transaction case standard in terms of disclosure law is inappropriate for the purpose of effective. Fourth, the government's plan to realize the publicly announced price did not reflect the effective control characteristics of Dokdo's publicly announced land price calculation, but rather reflected market price fluctuations and the realization rate, which led to the first decline in land prices. 본 연구의 목적은 독도리 공시지가 현황을 분석하여, 국가 영향력 행사의 결과물인 독도리 실효 지배 강화를 위한 대안을 제시하는 것에 있다. 분석방법은 기술적 분석방법으로 공시가 변동현황을 확인하여, 독도리 공시지가를 대상으로 하는 공시법 측면, 지적제도 측면, 공시지가 현실화 계획 측면에서 분석하고, 독도리 공시지가 실태분석 선행연구, 국토교통부 및 울릉군청 공시지가 자료를 기반으로 연구하였다. 연구의 시간적 범위는 선행연구인 이범관 교수의『독도리 공시지가의 특성 연구』발표에 따른 연장선으로 2012년부터 2023년까지로 한정한다. 분석 결과 첫째, 2000년부터 2022년까지 독도의 공시지가 산정의 목적이 영유권 강화를 위한 목적을 내포하고 있었고 이는 꾸준한 지가상승으로 나타났다. 둘째, 공간정보 관리법에 따라 지적공부에는 공시지가를 필수적 기재사항으로 하는 수단적인 법률을 독도의 실효 지배를 강화할 수 있는 수단으로 활용하고 있었다. 셋째, 공시법 측면의 단순 거래사례 기준은 실효 지배 목적에 부적절하다. 넷째, 정부의 공시가격 현실화 계획은 독도의 공시지가 산정의 실효 지배 특성을 반영하지 않고, 시세변동과 현실화율을 반영하였기 때문에 최초의 지가 하락이 발생한 것으로 나타났다.

Recently, the issue of refunding deposits on deposits has become a hot topic in the housing market. It has been reported so far as an incident that caused anxiety and economic crisis among tenants with the news of the so-called’Cheonse King’, in which individuals own hundreds or thousands of units. The core of the Jeonse deposit refund problem begins with the risk of not getting the deposit refunded. In line with the rapidly rising real estate value over the past five years, the value of collateral has skyrocketed, and along with the skyrocketing real estate market, liquid funds from all over the country have flocked to gap investment for capital gains in the rising real estate market. Debt-to-debt, Youngkkeul coined words to attract equity capital and maximum loan to purchase a house as soon as possible in the skyrocketing real estate market. As a basic investment method, they tried to increase their assets by purchasing them when the market value was low and disposing of them when the value rose to generate capital gains, but this did not last long. The real estate policy of the Moon Jae-in administration, which forced multi-homed people to dispose of their houses by strengthening the comprehensive real estate tax and capital gains tax, expected the housing market to stabilize due to an increase in supply in the housing market due to excessive tax regulations, and a natural oversupply through this, but this was due to the tax transfer phenomenon. It led to a surge in the rental market and, as a result, made a rise in housing prices without a break. People who do not own their own home in Seoul have shown such a huge increase that it is impossible to own their own home in Seoul for a lifetime. In the case of apartments, there was a difference of more than 700 million to 1 billion over several years. Due to excessive real estate soaring, the new government in 2021 has suppressed purchasing power so that additional real estate cannot be purchased due to rising interest rates since its inauguration. This will change the trend of the housing market at a rapid pace. At the same time, investors who bought houses in a rising market could not afford to pay huge interest rates due to interest rate hikes. When the couple receives their monthly wages, each person's monthly wages reach the point where they are repaid in principal and interest. Those who could not afford the increased interest tried to give up the interest burden or pass it on to the tenant, such as disposing of it or looking for a tenant for cheonsei or monthly rent. As a result, supply in the rental market increases, and the rental market appears to be stabilizing. However, this is not the level of the normalized market before the surge, but the level of a certain portion of decline due to interest rate hikes after the surge. As such, the rental market is still supplied to the market at a price that exceeds the normal price, so the number of vacant houses is increasing. Here, in order to solve the housing problem, tenants flocked to relatively cheap villa rentals. In this process, some immoral and blind spots in the law are exploited to rent the villa for a deposit equivalent to the sale price of the newly built villa to a person with bad credit or bankruptcy (limited guardian) who is incapable of socially, economically and legally fulfilling their responsibilities. It can be said that there was a problem of not returning the Jeonse deposit due to transfer. This study analyzes the structure of the Jeonse deposit return problem in the housing rental market from the perspectives of sales agencies, certified real estate agents, lessees, and Housing City Guarantee Corporation. It was pointed out that there is a problem with the effectiveness of presenting the same contents prescribed in the current Certified Real Estate Agent Act by reviewing the alternative measures of the Ministry of Land, Infrastructure and Transport, which occur because it is targeted for rea...

Blood Vessel Regeneration using Human Umbilical Cord-derived Endothelial Progenitor Cells in Cyclophosphamide-treated Immune-deficient Mice

조재진 KOREAN ACADAMY OF ORAL BIOLOGY 2011 International Journal of Oral Biology Vol.36 No.3

Endothelial cells are a vital constituent of most mammalian organs and are required to maintain the integrity of these tissues. These cells also play a major role in angiogenesis, inflammatory reactions, and in the regulation of thrombosis. Angiogenesis facilitates pulp formation and produces the vessels which are essential for the maintenance of tooth homeostasis. These vessels can also be used in bone and tissue regeneration, and in surgical procedures to place implants or to remove cancerous tissue. Furthermore, endothelial cell regeneration is the most critical component of the tooth generation process. The aim of the present study was to stimulate endothelial regeneration at a site of acute cyclophosphamide (CP)-induced endothelial injury by treatment with human umbilical cord-derived endothelial/mesenchymal stem cells (hEPCs). We randomly assigned 16 to 20-week-old female NOD/SCID mice into three separate groups, a hEPC (1 × 10 5 cells) transplanted, 300mg/kg CP treated and saline (control) group. The mice were sacrificed on days 5 and 10 and blood was collected via the abdominal aorta for analysis. The alanine transaminase (ALT), aspartate aminotransferase (AST), serum alkaline phosphatase (s-ALP), and albumin (ALB) levels were then evaluated. Tissue sections from the livers and kidneys were stained with hematoxylin and eosin (HE) for microscopic analysis and were subjected to immunohistochemistry to evaluate any changes in the endothelial layer. CP treatment caused a weight reduction after one day. The kidney/body weight ratio increased in the hEPC treated animals compared with the CP only group at 10 days. Moreover, hEPC treatment resulted in reduced s-ALP, AST, ALT levels compared with the CP only group at 10 days. The CP only animals further showed endothelial injuries at five days which were recovered by hEPC treatment at 10 days. The number of CD31-positive cells was increased by hEPC treatment at both 5 and 10 days. In conclusion, the CP-induced disruption of endothelial cells is recovered by hEPC treatment, indicating that hEPC transplantation has potential benefits in the treatment of endothelial damage.

Purpose: We compared optical biometric measurements made using new swept-source optical-coherence tomography, low-coherence reflectometry, autokeratometry, and A-scan biometry. Methods: In total, 86 eyes of 47 patients were included. Axial length, lens thickness, central corneal thickness, anterior chamber depth, and corneal curvature were measured using the Anterion® (Heidelberg Engineering, inc., Heidelberg, Germany) and Lenstar LS 900® (Haag-Streit AG, Koeniz, Switzerland) platforms. Corneal curvature and axial length were measured using the Essilor AKR 750® (Essilor instruments, France, Charenton-le-Pont) and PacScan 300A® (Sonomed Inc., Chicago, IL, USA) platforms, respectively. The evaluated biometric parameters were compared and verified; intraclass correlation coefficients and Bland-Altman plots were used to analyze statistical agreement. Results: The differences between the Anterion® and Lenstar LS 900® platforms in terms of axial length, lens thickness, central corneal thickness, anterior chamber depth, and white-to-white diameter were -0.02 ± 0.08, 0.08 ± 0.13, -2.66 ± 11.12, 0.05 ± 0.12, and 0.08 ± 0.26, respectively. All values were statistically significant. The mean corneal curvature between Anterion® and Lenstar LS 900® had a statistically significant difference of -0.08 ± 0.47, while the difference between the Anterion® and AKR 750® platforms was not significant. Biometric parameters measured using an Anterion® and other devices showed a strong positive correlation when assessed using Pearson’s correlation analysis; there was good agreement between the results when analyzed using intraclass correlation coefficients and Bland-Altman plots. Conclusions: Optical biometric measurements made using the Anterion® platform were not significantly different from those obtained using other devices, but there were significant differences compared to the Lenstar LS 900® platform. Since these significant differences could influence decision making during intraocular lens selection for cataract surgery, the values are clinically useful for reference. 목적: Anterion®으로 측정한 안구 생체계측과 Lenstar LS900®, Essilor AKR 750®, PacScan300A®로 측정한 안구계측을 비교하여Anterion®의 유용성을 알아보고자 하였다. 대상과 방법: 환자 47명, 86안을 선정하여 Anterion®, Lenstar®로 안축장, 수정체두께, 중심각막두께, 전방깊이, 각막곡률, AKR 750® 으로 각막곡률, PacScan 300A®로 안축장을 측정 후, 차이값과 상관관계를 확인했으며, 급내상관계수와 Bland-Altman plot으로 일치도를 분석하였다. 결과: Anterion®, Lenstar®로 측정한 안축장, 수정체두께, 중심각막두께, 전방깊이, 각막윤부직경은 -0.02 ± 0.08, 0.08 ± 0.13, -2.66 ± 11.12, 0.05 ± 0.12, 0.08 ± 0.26으로 유의미한 차이를 보였다. Anterion®과 Lenstar®로 측정한 평균 각막굴절력은 -0.08 ± 0.47로 유의미한 차이를 보인 반면, AKR 750®와 비교했을 때는 차이가 없었다. Anterion®의 측정값은 다른 기기의 측정값과 피어슨상관계수를 검증했을 때 강한 양의 상관관계를 보였고 급내상관계수, Bland-Altman plot에서 높은 일치도를 보였다. 결론: Anterion®은 기존 기기들과 비교했을 때 차이의 절대값은 크지 않으나, Lenstar®의 경우 통계적으로 유의한 차이를 보인 지표들이 있었다. 백내장수술에서 인공수정체를 결정하는 등 임상 적용 시 기존 기기와 다른 결과를 만들 수 있기 때문에 주의할 필요가있다.
