There are two methods for evaluating two or more mutually exclusive projects. One is a total investment approach and the other is an incremental investment approach. The former can rank projects by the criterion of the net present value, but the latter can't do it. An incremental investment approach is only possible when all pairwise alternatives are compared. Thus an incremental investment approach is superior in ranking them over an incremental investment approach. To do so, a principle of comparison must be established. Comparisons of profitability are reasonable when operating the same amount of investment over the same period of time. One principle is that all projects are invested in the largest of the projects. Another principle is that all projects are invested during the longest project life of the projects. In this paper, even if the principle is followed, it will be shown that the external rate of return fails to rank them. However, the productive rate of return criterion would prove to be able to rank them like the net present value standard, provided that the principle of comparison is kept. In addition, rate of returns can be assessed so that all mutually exclusive projects can be compared at once, such as on the criterion of the net present value. That is, it can be also compared with many other returns, such as the profit rates on financial investments or real investments.

Since Civil Law recognizes the freedom of a testament, it recognizes the freedom allowing the decedent to dispose his/her own property at his/her own intention. However, in order to prevent various abuses which may occur when the principle of freedom of testament is carried out unlimited, secured portion system is stipulated. So, absolute freedom of property disposed by the deceased is limited. Likewise, the secured portion system is introduced as the system to resolve the contradiction that exists between principle of freedom of testament and legal inheritance. Since Supreme Court Decision 2010DA50809 delivered on May 24, 2012 includes major legal issues such as how to exercise of claim of return for secured portions, transfer of the secured proportion or the claim of return for secured portions, and exercise of claim of return for secured portions against a third party. So, it has a very important meaning. In this paper, legal issues regarding the exercise of claim of return for secured portions have been reviewed with this decision.

Generally a return current plane(RCP) of high speed digital and analog part is partitioned. This is achieved in order to decrease the noise interference between subsystem in PCBs(Printed Circuit Boards). However, when the connected signal line exists between each subsystem, this partition will cause unwanted effects. In a EMI(Electromagnetic Interference) point of view, the partition of the return current plane becomes a primary factor to increase the radiated emission. Component bridge(CB) is used for the way of maintaining radiated emission, still specific user's guide doesn't give sufficient principle. In a view point of EMI, design principle of multi-CB using method will be analyzed by measurement. And design principle of noise mitigation will be provided. Generally interval of multi-CB is ${\lambda}/20$ ferrite bead. In this study, When multi-CB connection is applied, design principle of ferrite bead and chip resistor is proved by measurement. Multi-connected chip resistance$(0{\Omega})$ is proved to be more effective design method in the point of EMI.

Generally a return current plane(RCP) of high speed digital and analog part is partitioned. This is achieved in order to decrease the noise interference between subsystem in PCBs(Printed Circuit Boards). However, when the connected signal line exists between each sub system, this partition will cause unwanted effects. In a circuital point of view, RCP partition has a bad influence upon signal integrity. In a EMI(Electromagnetic Interference) point of view, the partition of the return current plane becomes a primary factor to increase the radiated emission. Component bridge(CB) is usecl for the way of maintaining signal integrity, still specific user's guide doesn't give sufficient principle.

The purpose of this article is to study on the Correlative linkage between the cosmic principle of birth-growth and contraction-recess and the Non action Tao. The split time between birth-growth and contraction-recess is the conflict between the Prior Time and Posterior Time as the Great Renewal. The cycle of this Chaotic Renewals is the cycle of a cosmic circulation as 129,600 years. In relation to the correlative linkage of function, Jeong-san Sangje governs all the beings of the universe by means of the cosmic principle birth-growth and contraction-recess. Also Jeong-san Sangje, using the Non action Tao governing all the beings of the universe and let them exist as the original selves. Thus, the two necessities are mutual interdependent and mutual complementary. In relation to the correlative linkage of substance, Jeong-san Sangje is included in the cosmic life which forms of all the existences. That is personal God of Jeong-san Sangje that is a part of the cosmic life. So that Jeong-san Sangje is included in the cosmic life, the basis of all the cosmic affairs. He is also subordinate to the cosmic principle but he simultaneously governs it. Jeong-san Sangje is trans-versal mediator between the cosmic principle and the cosmic life of Non action Tao, since it is the origin of his mind. To understand the nature of Jeong-san Sangje who becomes one with the cosmic life, the old causal way of thinking which inquires the timely order and seeks for causes and effects should be abandoned. The new way of thinking is thus different from the old one. The core of cosmic life is abstracted as the essence-energy and god-blood. This structure is similar to the cosmic principle of birth-growth and contraction-recess. The death is a kind of event caused by the depletion of the essence, and all beings could altered into the god. It also would be returned to the natural birth place of the cosmos, as it were, that can be called the 'Return to the Origin'. As the cosmos goes to the new epoch, humans have been living together with the cosmic principle. Now we can expect the Posterior Time to open to humans as cosmic life of Non action Tao.

The purpose of this study is to identify the expression methods of uncanny images shown in contemporary fashion through the visual expression methods of plastic arts. The study results are as following. First, there is a concept-forming element of 'The return of Repressed', which is a psychological mechanism for generating uncanny sets to the component of 'repression' and 'return'. 'Repression' herein consisted of 'unconsciousness', 'the other', and 'anxiety', while the return was composed of 'trauma' and 'repetition compulsion'. Second, there are visual expression methods of the uncanny in contemporary art. The subject of 'repressed things' was expressed as grotesque and having a terrible look. 'Fragmented body' was analyzed as 'dismantling' by mutilation, 'combination' placing cut body parts in other places, and 'damage' suffering from an illness or accident. 'Fear of death' was shown as 'anatomy' reminiscent of death and 'iconography of death' meaning return of the dead. 'Post-human' was a surrealistic being such as a monster and mechanized human, and was analyzed as 'gene variation' and 'cyborg'. Third, the methods of visual expression of the uncanny reflected on contemporary fashion was analyzed as 'fragmented body', 'fear of death', and 'post-human'. 'Fragmented body' appeared as the object reminiscent of the fragmented body, 'dismantling and combination of the body', and 'damage of the body' through the distortion of the clothing construction principle. 'Fear of death' visualized the characteristic elements of the subject reminiscent of death as 'iconography of death' and 'symbolic object of death' through the motif. 'Post-human' was the description of the subject beyond the body's function and form, and was shown as 'gene variation' and 'cyborg'.

A weakly nonlinear solution is presented for the two-dimensional wave kinematics forced by a generic wavemaker of variable-draft. The solution is valid for both piston and hinged wavemakers of variable-draft that may be double articulated. The second-order propagating waves generated by a planar wave board are composed of two components; viz., a Stokes second-order wave and a second-harmonic wave forced by the wavemaker which travels at a different speed. A previously neglected time-independent solution that is required to satisfy a kinematic boundary condition on the wavemaker as well as a mixed boundary condition on the free surface is included for the first time. A component of the time-independent solution is found to accurately estimate the mean return current(correct to second-order) in a closed wave flume. This mean return current is usually estimated from kinematic considerations by a conservation of mass principle.

This paper primarily focuses on the highest deity, the Upper Thearch of the Nine Heavens (officially translated as 'The Supreme God of the Ninth Heaven'), in the Korean new religious movement (NRM) Daesoon Jinrihoe and the true minister of the myriad spirits in the Taiwanese NRM, Yiguan Dao, the Upper Thearch of Manifest Luminosity. As the two both serve as highly representative "Upper Thearch" beliefs in emerging NRMs, I attempt a comparative analysis of the source of these beliefs, their characteristics, and the links that exist between them. On the basis of ancient Chinese classics and Daoist texts, along with Daesoon Jinrihoe's scriptures and works from Yiguan Dao's Canon, I try to understand the distinguishing features of cosmological ideas from both religious movements. For example, because the Upper Thearch of the Nine Heavens could not bear to see the human realm growing ever more disordered and in order to improve worldly conditions, he traveled to the harmonized realm of deities, and therefore descended into the world to make a great itineration and enlighten the people through his teachings. In the end, he came to Korea and was reborn as Kang Jeungsan (secular name: Kang Il-Sun) in Gaekmang Village. In the Human Realm, he spread his transformative teachings to the people which were later became the doctrines of the Virtuous Concordance of Yin and Yang, Harmonious Union between Divine Beings and Human Beings, the Resolution of Grievances for Mutual Beneficence, and Perfected Unification (jingyeong 真境) with the Dao. Yiguan Dao; however, explains that the source of humanity is the "Heaven of Principle" (Litian 理天), and people are "Buddha's Children of the Original Embryo" (Yuantai Fozi 原胎佛子), created by the Upper Thearch of Manifest Luminosity, who came to world to govern and impart spiritual refinement, before returning to his native place in the Heaven of Principle. Yet, because he became infatuated with the world of mortals, he forgot the path of his return. Therefore, the Eternal Mother sent Maitreya Buddha, the Living Buddha Jigong 濟公, and the Bodhisattva of Moon Wisdom (Yuehui pusa 月慧菩薩) to descend to the human world and teach the people, so that they may acknowledge the Eternal Mother as the root of return, achieve their return to the origin, and go back to the home of the Eternal Mother in the Heaven of Principle. Both Daesoon Jinrihoe and Yiguan Dao refer to their highest deity, the true ministers of the myriad spirits, with the simple title "Upper Thearch." This phenomenon also has some ties to God in the western Biblical tradition but also has some key differences. In investigating the sources of these two deities, we find that they likely took shape during the Yinshang (殷商) period and have some relationship to the Upper Thearch of Chinese antiquity. The questions raised in this research are quite interesting and deserving of deeper comparative study.

In International trade the buyer and seller are normally separated from on another not only by distance but also by differences in language and culture. It is rarely possible for the performance of obligations to be simultaneous and the performance of contracts therefore calls for trust in a situation in which the parties are unlikely to feel able to trust each other unless they have a longstanding and successful relationship. Thus the seller under an international contract of sale will not wish to surrender documents of title to goods to the buyer until he has at least an assurance of payment, and no buyer will wish to pay for goods until he has received them. A gap of distrust thus exists which is often bridged by the undertaking of an intermediary known and trusted by both parties who will undertake on his own liability to pay the seller the contract price in return for the documents of title and then pass the documents to the buyer in return for the reimbursement. This is a common explanation of the theory behind the documentary letter of credit in which the undertaking of a bank of international repute serves as a "guarantee" to each party that the other will perform his obligations. The independence principle, also referred to as the "autonomy principle", is at the core of letter of credit or bank guarantee law. This principle provides that the letter of credit or bank guarantee is independent of the underlying contractual commitment - that is, the transaction that the credit is intented to secure - between the applicant and the beneficiary ; the credit is also independent of the relationship between the bank and its customer, the applicant. The most important exception to the independence principle is the doctrine of fraud in the transaction. A strict interpretation of the rule that the guarantee is independent of the underlying transaction would lead to the conclusion that neither fraud nor manifest abuse of rights by the beneficiary would constitute an objection to payment. There is one major problem related to "Independent guarantees", namely abusive or unfair callings. The beneficiary may make an unfair calling under the guarantee. The countermeasure of beneficiary's unfair calling divided three cases. First, advance countermeasure namely by contract. In other words, when the formation of the contract, the parties must insert the Force Majeure Clause, Arbitration Clause to Contract, and clear statement to the condition for demand calling. Second, post countermeasure namely by court. Many countries, including the United States, authorize the courts to grant an order enjoining the issuer from paying or enjoining the beneficiary from receiving payment under the guaranty letter. Third, Export Insurance. For example, the Export Credit Guarantees Department is prepared, subject to certain conditions, to cover the risk of unfair calling. Of course, KEIC in Korea is cover the risk of the all things for guarantees. On international projects, contractor performance is usually guaranteed by either a standby letters of credit or Independent guarantee. These instruments will be care the parties.

Sinuous antenna is utilized in a number of application like direction-finding system that require ultra wideband, but because of high input impedance of the antenna, it is difficult to design low-profile antenna and balun. In this study, we used Babinet's principle and proposed linear 2-arm slot sinuous antenna that is divided sinuous 6 cell with equal spacing between the most largest radius $R_1=31.83mm$ and the smallest radius $R_p=1.7mm$ instead of exponential 2-arm strip sinuous antenna for 2-18[GHz] frequency band to obtain low input impedance, and we have studied -10dB bandwidth of antenna when has been fed by $80{\Omega}$ instead of $188{\Omega}$ at feeder point. As a result, we have obtained return loss below than -10dB for about 4-18[GHz] frequency range in the case of slot antenna, but at all frequency band, return loss was above -10dB in the case of strip antenna.
