Decree on the Management of Apartment Houses. Article 36 (Liability for warranty Repair Defects), Article 37 (About Repair Defect, etc), and its implementing ordinances, Article 36 (Term of warranty liability) Article 37 (Defect criteria), Article 38 (procedure of Repair defect), Article 39 (type of warranty liability), Enforcement Rule Article 17 (Certifiation of warranty liability). On the basis of the upper Decree, In spite of Standard and forms of 'Completion of Repair Defect' was exist, it was hard to receive 'End of Confirmation' in practice. The purpose of this study is to propose basics in order that Practitioners can apply problems and improvements about Decree on the Management of Apartment Houses.

Gauss Sieve is an algorithm for solving SVP and requires exponential time and space complexity. The terminationcondition of the Sieve is determined by the size of the constructed list and the number of collisions related to space complexity. The term 'collision' refers to the state in which the sampled vector is reduced to the vector that is already inthe list. if collisions occur more than a certain number of times, the algorithm terminates. When executing previous algorithms, we noticed that unnecessary operations continued even after the shortest vector was found. This means that the existing termination condition is set larger than necessary. In this paper, after identifying the point where unnecessary operations are repeated, optimization is performed on the number of operations required. The tests are conducted by adjusting the threshold of the collision that becomes the termination condition and the distribution in whichthe sample vector is generated. According to the experiments, the operation that occupies the largest proportion decreased by62.6%. The space and time complexity also decreased by 4.3 and 1.6%, respectively.

본 논문에서는 계층셀 시스템에서 이동단말의 속도에 따른 채널 할당 기법이 갖는 QoS 차이를 극복하기 위하여 두가지 핸드오프 우선 순위 기법을 제안한다. 첫 번째 기법은 매크로셀에 고속 핸드오프 호를 위한 전용채널을 할당하여 고속 단말의 핸드오프 강제 종료율을 낮추어 줌으로써 서로 다른 속도 그룹에 속한 단말들에게 동일한 서비스 품질을 유지할 수 있도록 한다. 두 번째 제안하는 기법에서는 시스템 내 트래픽 양의 증가시에 발생하는 핸드오프 호의 성능 저하를 방지하기 위하여 마이크로셀 경계에 핸드오프 호를 위한 큐를 도입한다. 시뮬레이션 결과 핸드오프 호 강제 종료율에 있어서 높은 성능 개선을 보이며 특히 저속 단말에 준하는 수준으로 고속 단말의 QoS를 보장하였다. 또한 오버플로우 대 테이크백 비율(the ratio of take-back to overflow)을 고려할 때 기존 방식에 비하여 제안하는 방식에서 보다 많은 호가 올바른 셀 계층에서 진행하게 되어 전체 시스템의 효율을 높이는 것을 확인하였다.

최근 표준화가 완료된 HEVO(High Efficiency Video Coding)에서는 계층적 구조를 갖는 가변블록의 크기를 사용하고 재귀적으로 부호화를 수행사여, 최적의 부호화단위(CU: Coding Unit) 분할 구조와 예측단위(PU: Prediction Unit)를 결정함으로써 높은 부호화 효율을 얻을 수 있는 반면 부호화 복잡도가 증가하는 문제가 있다. 본 논문에서는 부호화기의 복잡도를 감소시키기 위한 고속 부호화 알고리즘으로 고속 모드 결정 기법을 제안한다. 제안기법은 상위 깊이(CU: Coding Unit)의 최적 모드와 부호화 율-왜곡 비용을 이용해서 현재 깊이 CU에서의 특정 모드의 율-왜곡 비용 계산을 생략함으로써 PU 탐색을 조기 종료한다. 즉, 상위 깊이 CU의 조건에 따라 화면간 예측 모드의 일부 또는 화면내 예측을 수행하지 않는다. 실험결과 제안기법은 HM 12.0대비 0.2%의 비트 증가에 22.9%의 계산시간 감소 효과를 얻을 수 있음을 확인하였다.

In case of sunken tankers, remaining-oil recovery operation should be conducted due to possible oil spill accident. However, the deep sea operation make difficulties in checking the completion of remaining oil recovery process, therefore the work termination procedure is very important. In this paper, a reasonable work termination procedure through the comparison and analysis of two cases(Youil No.1 and Osung No.3, Kyung-Shin) which were performed in different method, using disparate equipment. By investigating previously applied methods and techniques, work speed, safety and expenses were compared. The proposed ending procedure of the remaining-oil recovery project is to recover the remaining oil from each cargo tanks and to clean up such tanks whilst an independent surveyor proceeds to a confirmation procedure whereby said surveyor checks out whether any remaining oil exists by putting a stick in each cleaned up tanks and opening up the hatch cover of the tanks or the top place of the tanks to confirm the cleanness of oil. Such procedure shall be done through discussion by the ordering party, contractor and the independent surveyor all together with a flexible application.

공정거래위원회(위원장 김동수)가 하도급거래에서 서면발급 및 보존관행을 정착시키기 위해 "바람직한 서면발급 및 보존에 관한 가이드라인"을 제정해 1월 1일부터 시행에 들어갔다. 가이드라인에는 ${\bigtriangleup}$하도급계약서(추가 변경계약서 포함) ${\bigtriangleup}$하도급계약 확인서면 ${\bigtriangleup}$목적물 등 수령증명서 ${\bigtriangleup}$검사결과 통지서 ${\bigtriangleup}$감액서면 ${\bigtriangleup}$기술자료 제공 요구서 ${\bigtriangleup}$계약변경 내역 통지서 등 7건은 의무발급을, ${\bigtriangleup}$목적물 등의 검사결과 및 검사 종료일 ${\bigtriangleup}$하도급대금의 지급일 지급금액 및 지급수단 ${\bigtriangleup}$설계 변경 등에 따라 하도급대금을 조정했을 때 사유 ${\bigtriangleup}$원재료 등의 가격변동 등에 따라 수급사업자가 하도급 대금 조정을 신청한 경우 협의내용 및 조정사유 등 7건은 보존 서면으로 명시했다. 이번 가이드라인은 동반성장협약 평가 항목에도 반영될 예정이다. 또한 공정거래위원회는 하도급법상 서면발급 또는 보존의무를 위반해 경고조치를 받을 때에는 교육이수를 권고하는 한편, 서면 미발급 등 혐의가 반복될 때에는 최고경영자(CEO)가 교육(3개월에 3시간)을 이수토록 규정했다. 특히 서면실태조사에서 서면 미발급 미보존 혐의가 장기간 상습적으로 이뤄졌다는 사실이 확인되면 직권조사를 거쳐 엄중할 방침이다.

The latest video coding standard, high efficiency video coding (HEVC) achieves high coding efficiency by employing a quadtree-based coding unit (CU) block partitioning structure which allows recursive splitting into four equally sized blocks. At each depth level, each CU is partitioned into variable sized blocks of prediction units (PUs). However, the determination of the best CU partition for each coding tree unit (CTU) and the best PU mode for each CU causes a dramatic increase in computational complexity. To reduce such computational complexity, we propose a fast PU decision algorithm that early terminates PU search. The proposed method skips the computation of R-D cost for certain PU modes in the current CU based on the best mode and the rate-distortion (RD) cost of the upper depth CU. Experimental results show that the proposed method reduces the computational complexity of HM12.0 to 18.1% with only 0.2% increases in BD-rate.

Kidney bean was used in the brewing of Takju. The Takju formed varied the percentage of kidney bean used; that is, 0%(only rice) in $T_{-1}$, 100%(only kidney bean) in $T_{-2}$, 90% in $T_{-3}$, 80% in $T_{-4}$, 70% in $T_{-5}$, 60% in $T_{-6}$, and 50% in $T_{-7}$. We determined the total sugar, pH, reducing sugar, alcohol production, acidity, and DPPH free radical scavenging activity of Takju. The acidic value of $T_{-1}$ was above that of $T_{-6}$, and the pH of $T_{-2}$ was above that of $T_{-1}$. Both satisfy the food code parameters (namely, below 0.5 in acidity, 3.8~4.7 in pH). The alcohol production of $T_{-1}$ was above that of $T_{-2}$. For 2 days of fermentation, the reducing sugar of $T_{-1}$ totaled 2, down from 4.96%. After fermentation, there was not much difference from 4 to 12 days. The antioxidative effect of $T_{-1}$ proved to be much better than those of the other. Thus, we can be seen that these results thus indicate that the role of kidney bean added to Takju show good antioxidative activity. From the result of sensory test, we also concluded that the taste of Takju kidney bean is very similar to that of Takju with rice.

This paper examines whether investors have adapted to the venture capital(VC) investment style. VC firms invest in privately held companies and generate returns by selling them after the lock-up period expires. We analyze the impact on stock prices before and after the lock-up period expiration, and compare the Cumulative Abnormal Return(CAR) between the past period(2015-2017) and the recent period(2020-2022) to investigate the effect of the second venture boom. The main findings are as follows. First, unlike in the past, stock price returns around the lock-up period expiration have been lower than the KOSDAQ index in recent years. Second, the impact on stock prices is significant for both 1-month and 12-month lock-up periods. Specifically, it is confirmed that stocks held by venture capital and professional investors with a 1-month lock-up period respond in advance to their information after the second venture boom. Finally, we find that there is a difference in CAR depending on whether or not the company received VC investment after the second venture boom. Based on our findings, we suggest that VC firms need to revise their exit strategies to improve performance. This includes finding ways to reduce information asymmetry and fees, as well as developing strategies to mitigate market volatility. Additionally, the current lock-up period for VCs should be reconsidered as it may increase the risk of stock price decline. We recommend that the government revise the scope and duration of lock-up periods to protect investors after IPO.
