Normally, monetary penalties for breach of agreement will be stipulated in the contract. The contractor parties, who fail to fulfill the agreement, are required to pay the other parties a certain amount or proportion of money as a fine. However, it is worth our study - whether or not the scope of monetary penalty implementation and bases for determination of a fine will cover the losses of social and administrative costs incurred by the interruption of the contract. This research is about the best timing for government to cancel the freeway repair work contracts. Under the goal of the maximum social welfare, the limitation of government spending for the social and administrative costs invoked by interruption of contracts will have to be considered to attain the best timing of contracts' suspension or deferment. According to the factors of social and administrative costs, the best time point is calculated to reduce the loss of the aforesaid costs, which can also be used as theoretical basis for the future road-widening construction at home.

Analysis of construction tender documents in overseas projects is a very important issue from a risk management point of view. Unfortunately, majority of construction firms are biased by winning contracts without in-depth analysis of tender documents. As a result, many contractors have incurred loss in overseas projects. Although a lot of risk analysis techniques have been introduced, most of them focus project's external unexpected risks such as country conditions and owner's financial standing. However, because those external risks are difficult to control and take preemptive action, we need to concentrate on project inherent risks. Based on this premise, this paper proposes a project-oriented risk mining approach which could detect and extract project risk factors automatically before they are materialized and assess them. This study presents a methodology regarding how to extract potential risks which exist in owner's project requirements and project tender documents using state of the art data analysis method such as text mining, data mining, and information visualization. The project-oriented risk mining approach is expected to effectively reflect project characteristics to the project risk management and could provide construction firms with valuable business intelligence.

본 연구는 정기용선계약 하에서 MT Kos호 사건을 중심으로 선박 회수에 따라 발생한 손해를 분석하는 것에 있다. 이 사건에서 용선자는 선주의 회수통지를 받으면 화물을 양하할 것과 본선은 Angra doe Reis에서 하루 동안 체선할 것에 합의하였다. 그런데 거기에서 본선은 2.64일 동안 체선하였다. 그 쟁점은 선주가 이 동안 선박에 소요된 연료비를 포함한 비용을 지급받을 수 있는지의 여부이었다. 선주는 (1) 용선계약의 사용과 보상조항, (2) 새로운 계약의 성립, (3) 임치법을 근거로 청구권의 존재를 주장하였다. 제1심 법원은 선주의 청구를 인정하였는데, 그 근거로서 (3)의 임치만을 인정하고 다른 근거는 완전히 배척하였다. 항소법원은 (3)의 임치도 부정하였지만, 화물 양륙에 실제로 소요된 연료비에 대한 청구는 인정하였다. MT Kos호 사건판결의 중요성은 원칙적으로 보상클레임을 지지한 것에 있다. 그런데 이 사건의 반대의견에서는 관련조항의 범위를 부당하게 확장한 것이라고 하여 비판적인 견해를 개진하였다. 이 사건에서 임치법은 적정한 구제수단으로서 제공되고 있지만, 특히 계약상의 확실성이 매우 중요한 해운분야에서 용선계약표준서식상의 보상 범위로까지 확대할 필요는 없다고 본다. 그런데 향후 보상조항과 관련된 클레임의 경우 정기용선계약상의 보상조항이 적용되는 상황에까지 확대될 가능성을 모색할 수도 있기 때문에, 이 사건 이후의 판례의 결과가 주목된다.

On 9 March 2017, a Tribunal constituted under the ICSID Convention issued its ruling in the case of Ansung Housing v. People's Republic of China, dismissing with prejudice all claims made by the Claimant, Ansung Housing Co., Ltd., in its Request for Arbitration, pursuant to ICSID Arbitration Rule 41(5). Ansung Housing v. PRC has drawn attention since it is the first case where an investor with Korean nationality initiated an ICSID arbitration on the basis of the Korea-China Bilateral Investment Treaty (BIT) as amended in 2007 between the Republic of Korea and the People's Republic of China. The Tribunal finds that its ruling is about a lack of jurisdiction of the ICSID and of its own competence as well as regarding manifest lack of legal merit due to a lack of temporal jurisdiction, since a Respondent's Rule 41(5) objection is concerned with the three-year limitation period in Article 9(7) of the Korea-China BIT. The Tribunal held that, under Article 9(7) of the Korea-China BIT, the limitation period begins with an investor's first knowledge of the fact that it has incurred loss or damage, not with the date on which it gains knowledge of the quantum of that loss or damage. Finally, the Tribunal held that Ansung submitted its dispute to ICSID and made its claim for purposes of Article 9(3) and (7) of the BIT after more than three years had elapsed from the date on which Ansung first acquired knowledge of loss or damage and that the claim is time-barred and, as such, is manifestly without legal merit. It remains to be seen whether the aggrieved Claimant initiates annulment proceedings before an ad hoc committee under the ICSID Convention. It is quite interesting to see whether the decisions by the Tribunal should be reversed on the basis of the Claimant's arguments as to the start date as well as the end date of the limitation period under the Korea-China BIT.

Article 77 sets forth the principle of prevention applied in several legal systems. Under this principle the party threatened by ooss as a consequence of a breach of contract by the other party is not permitted to await passively incurrence of the loss and then sue for damages. He is obliged to take adequate preventive measures to mitigate his loss. If the injured party abstains from taking such excessive measures he will not be considered to have failed to mitigate the loss under Article 77. The sanction provided in Article 77 against a party who fails to mitigate his loss only enables the other party to claim reduction in the damages. The reduction in damages under Article 77 is equal to the amount by which the loss should have been mitigated if the injured party had taken reasonable measures to avert or to lessen it. The aim of Article 77 is to encourage mitigation of the loss. The duty to mitigate the loss applies not only to a breach of contract in respect of an obligation whose performance is currently due. but also to an anticipatory breach of contract under Article 71. Article 85 contemplates that the buyer is in delay in fulfilling the latter obligation, or else that he fails to pay the price when payment is to be made concurrently with delivery of the goods by the seller. In both these situations of default, the seller who is either in possession of the goods or otherwise able to control their disposition must take measures, reasonable in the circumstances, to preserve them. The right of retention of the goods y the seller exists until he is reimbursed by the other party for the reasonable expenses incurred. Article 87 and Article 88 of the Convention grant different rights to the party obligated to take steps to preserve the goods; Article 87 allows him to deposit them in the warehouse of a third person, and Article 88 to sell them by whatever means appropriate. A difference exists between paragraph Article 88 (1) which grants the right to sell, and paragraph (2) which imposes the duty to take reasonable measures to sell the goods.

상법 제931조 4호에 불가항력에 관한 조항은 두가지 문제점을 내포하고 있다. 첫째, 그 적용 범위에 있어 명확하지 않으며, 둘째, 동조 1호의 열거된 면책사유와 불가항력은 중첩적 가능성이 제기될 수 있다. 불가항력이란 자연재해 및 제3자로 인한 외부적 영향에 의한 경우를 뜻한다. 후자의 해석으로 인한, 제3자의 외부적 영향으로 발생한 사건이라는 해석은 굉장히 광범위하고 포괄적인 의미인데, 이는 집행자의 해석에 따라 각각에 적용되기에 그 기준의 명확성에 대해 의심해 볼 여지가 있다. 더욱이 항공기사고로 인한 (지상) 제3자의 손해는 그 발생빈도가 적고, 또한 이는 신설조항으로 그 분석과 적용에 대한 연구는 필요하다. 하여 외부적 행위로 인하여 (지상) 제3자에게 (비계약적) 손해가 발생하였다면, 그 손해의 범위의 기준을 마련하는 것이 법률적용의 명확성에 있어 바람직하지 않을까 사료된다. 불가항력으로 인한 항공기운항자의 면책은 항공기운항자의 산업보호라는 입장에서 필요한 조항이 될 수도 있다. 반대로 이는 언제나 피해자의 보호법익과 상충된다. 하여, 법률적 보호에 있어 가장 우선시 고려해야 할 사항은 누구의 보호법익이 우선적으로 고려되어야 할 것인가 이므로, 기업보호라는 측면도 결코 간과할 수 없는 부분이지만, 예상치 못한 피해를 받은 항공기사고로 인한 (지상) 제3자의 보호는 기업보호에 앞서 담보되어야 할 보호법익이다. 다음으로 중첩적 가능성이란, 상법 제931조의 1호와 4호이다. 1호에 정치, 경제적 이유로 발생된 사건에 대한 면책이라는 규정을 두고 있는데, 이는 4호의 불가항력에 대한 해석과 맞물릴 수 있다. 위에서 설명한대로 불가항력의 해석상, 제3자의 외부적 영향의 원인으로 경치 경제적 이유로 발생되어지는 일련의 사건을 포함한다고 볼 수 있으므로, 이에 대한 중복적 규정이라는 의문이 생긴다. 결론적으로 향후에 발생하게 될 규정의 구체화와 양 당사자 간의 균형있는 보호를 위하여 이에 관한 고려가 필요하다고 사료된다.

K-IFRS 도입과 함께 기업 환경에 변화가 발생하는 상황에 대한 사례연구는 회계기준이 나아가야 할 방향성을 제시한다는 의의를 갖는다. 회계처리기준 변경에 따라 기업의 성과수치에 큰 차이를 보일 수 있으며 이는 실제 비즈니스에 큰 영향을 미칠 수도 있다. K-IFRS는 원칙중심의(Principle-Based) 회계처리기준이기 때문에, 필요적 규정에 대한 명시적 언급이 없는 경우가 많다. 따라서, 예전에 비해 회사 내부적으로 K-IFRS에 대한 대비가 철저히 이루어지지 않는다면, 상당한 애로사항이 발생할 수 있다. 이에 따른 A은행의 회계정책 및 대손충당금 설정시스템을 통한 대응방안을 살펴봄으로써 향후 K-IFRS 도입에 대응하여 기업 스스로가 혁신할 수 있는 방향성을 제시할 수 있었다.

Although current wireless mesh network (WMN) applications experience a perceptually uninterrupted hand-off, their throughput after the hand-off event may be significantly degraded due to the low available bandwidth of the mobile client's new master. In this paper, we propose a novel mobility management scheme for 802.11-based WMNs that enables both seamless hand-off for transparent communications, and bandwidth awareness for stable application performance after the hand-off process. To facilitate this, we (i) present a new buffer moment in support of the fast Layer-2 hand-off mechanism to cut the packet loss incurred in the hand-off process to zero and (ii) design a dynamic admission control to grant joining accepts to mesh clients. We evaluate the benefits and drawbacks of the proposal for both UDP and TCP traffic, as well as the fairness of the proposal. Our results show that the new scheme can not only minimize hand-off latency, but also maintain the current application rates of roaming users by choosing an appropriate new master for joining.

We consider transmission beamforming techniques for frequency-division-duplex (FDD) wireless communication systems using adaptive arrays to improve the signal quality of the array transmission link. We develop a simple effective transmission beamforming technique based on an approximated frequency tranlsation (AFT) to derive the tranmsiion beamforming weights from the uplink channel vector. This technique exploits the invariance of the short-time averaged fast fading statistics to small frequency translations. A simple approximate relationship that relates the transmission channel vector to the reception channel vector is derived. We have developed its practical alternative in which the frequency translation of the channel vector is performed at the principal angle of arrival (AOA) of the u;link synthestic angular spectrum instead of the mean AOA. To analyze the performance of the proposed methods, we consider the power loss incurred by applying the estimated channel vector instead of the true downlink channel vector. The performance is analyzed as a function of the mean AOA, the angular spread, the number of elements, frequncy difference between the uplink and the downlink, and the angle distribution. Their performance is also compared with that of the direct weight reuse method and the AOA based methods.

The aim of this study was to analyze characteristics of the barrier function of excised porcine buccal mucosa to the test compounds, estradiol, propranolol HCI, melatonin, and mannitol with a wide range of partition coefficient values. The permeability of melatonin was measured through frozen, stored, and fresh porcine buccal mucosa to examine the impact of storage conditions on the permeability of porcine buccal mucosa. The results demonstrated that the ex vivo permeability of the porcine buccal mucosa was greater for more lipophilic solutes, which was consistent with a series of molecules transported by passive transepithelial diffusion. The melatonin permeation profiles through frozen, stored, and fresh mucosa illustrated that damage was incurred by the freezing process of the mucosal tissue, leading to loss of the barrier function and thereby an increased permeation coefficient. It can be observed that the influence of compound lipophilicity on the association of the compounds with buccal mucosa was clear. The relationship between permeation coefficient and Log P values for the four compounds investigated demonstrated a proportional relationship, further confirming the importance of the lipophilicity of a compound to permeate the buccal mucosa. These results showed that the ex vivo porcine buccal mucosa model is a suitable tool to screen oral mucosal permeability.
