This work proposes a binomial method for pricing the cliquet options, which provide a guaranteed minimum annual return. The proposed binomial tree algorithm simplifies the standard binomial approach, which is problematic for cliquet options in the computational point of view, or other recent methods, which may be of intricate algorithm or require pre- or post-processing computations. Our method is simple, efficient and reliable in a Black-Scholes framework with constant interest rates and volatilities.

It has been five years since the Post-Construction Sale System of Housing was introduced. The purpose of this study is to identify objectives and effects of the Post-Construction Sale System of Housing and analyze change of profitability at different sales time from a supplier's point of view. Apartment buildings construction projects performed in Seoul are used for the case study. The present value of sales revenues, sensitivity and the present value of expected sales prices are analyzed. According to the findings, first, profits made from a Pre-construction sales system was 5.1%~6.2% higher than those from a Post-construction sales system. Among four plans of a Pre-construction sales system (A, B, C and D plan), sales revenue from the A plan, which takes a deposit at the time of starting construction, was the greatest. Second, increase of the rate of discount and decrease of sales revenues are in direct proportion. The bigger rate of discount leads actual reduction of sales revenues. Third, for the present value of sales revenues reflecting change in basic model construction cost, a Pre-construction sales system showed a little higher than that of a Post-construction sales system by approximately 2%. It should be known that this study suggests profitability of Pre-and Post-construction sales system by clearly measuring them in the supplier's point of view and calculates sales revenues, considering change of a sale price following change of sales time.

The Four Tenets of Daesoon thought are the Creative conjunction of the virtues of Eum and Yang, the Harmonious union of divine beings and human beings, the Resolution of grievances for the mutual beneficence of all life and the Realization of the Dao in the world. This article compares the concepts of the "Creative conjunction of the virtues of Eum and Yang", the "Harmonious union of divine beings and human beings" and the "Resolution of grievances for the mutual beneficence of all life" with "EumYangDaeDaeRon", "ShinMyonKiDeok", the Theory of Mutual Giving Life / Mutual Destruction (SangSaeng/SangGeukRon) of the Book of Changes and analyzes their common and different points. The conclusion is that Daesoon thought and the philosophy of the Book of Changes share common fundamental standpoints. However, the Daesoon thought defines the world of SeonCheon (the state before the Heaven and Earth have been created) as Mutual Giving Life (SangSaeng), and the world of HuCheon (the state after the Heaven and Earth have been created) as Mutual Destruction (SangGeuk). According to Daesoon thought the Mutual Destruction (SangGeuk) is seen as negative, while according to the philosophy of the Book of Changes the Theory of Mutual Giving Live/Mutual Destruction (SangSaeng/SangGeukRon) is viewed as a positive relationship of EumYangDaeDae. This is a point of difference between the Daesoon thought and the philosophy of the Book of Changes. According to EumYangDaeDae relationship theory the contradictory "other" is viewed not as an enemy, but as a necessary element that assures one's existence. When Buddhism and Christianity first came to existence, they did not belong to a main stream. Later, through continuous theorization and systematization they became generally accepted religions. The case of Confucianism was not much different. During Song dynasty in China Buddhism has contributed to the systematization and establishment of Neo-Confucianism; in the middle of 20th century the Confucian scholars of Hong Kong and Taiwan interpreted and defined Confucianism a new in the light of Western philosophy. Thus the "Modern Neo-Confucianism" came to existence. That's why the history of Confucianism is also called "the history of advancing and developing a concept". From this point of view the critical acceptance of some elements of Confucian, Buddhist, Taoist etc. traditions, as well as modern philosophy, by Daesoon, in order to achieve the systematization of Daesoon thought, is a very important process. As a part of this process, this essay explains the Daesoon thought from the point of view of the Book of Changes, which may be said to present the original East-Asian view of the world. Daesoon's emphasis of human dignity, the equality of sexes, the critics the hierarchical society etc. are rather "modern" and should be examined from the point of view of social science. Besides, leaving the boundaries of "modern philosophy", the concepts of "Harmonious union of divine beings and human beings", viewing the universe as one organism etc. should be approached from the point of view of Post-Modernism.

The purpose of this study is to reinterpretate the history of nursing and health care from the view-point of post-structuralism. It has been emphasized that the development of modern health care has been due to the progressive efforts of medicine and to medical discoveries. Medicine has dominated the history of health care rather than nursing or other health professions. The present study adopts the post-structural method by Foucault, which tries to unite language and knowledge. Foucault examines "the institutionalization of knowledge and the power exerted thereby, with special reference to the devices of social regulation and their function over the madness, the disease, the crime, and the sexuality. " The concept of power in Foucault's writing is that it is exerted spontaneously in verbal behaviors of individuals through knowledge of everyday life such as definition of body or mind, sexuality and relationship of family. Therefore as to the problem of power, this study tries to understand the meaning of the health care history through an analysis of the formation of medical discourse. In order to have authority in a power relation, the medical professional asserts that medical discourse is the most scientific knowledge. The authority of medical professionals can be reinforced by the fact that male medical professionals outnumber female. Devaluation of nursing care is reinforced by the medicine which has the legitimate authority through use of the political skills.

While the goal of new IT adoption in small and medium sized firms is to choose an optimal system to fit with their own environments and conditions, that of IT post-adoption usage is to fully implement new IT and maximize their benefits from it. Therefore, the decision-making environments of new IT adoption is definitely different from those of post-adoption. Also, The direct experience of IT usage can provide some learning effect and the change of users' beliefs on new IT. From this point of view, this study attempts to figure out the differences of influencing factors on IOS usage intention between adopters and non-adopters. The results show that there are clear differences of influencing factors between two groups. Non-adopter group shows that perceived financial cost and ability of use have significant influences on IOS usage intention, while relative advantage and perceived risk in adopter group have statistically significant influences on post-adoption usage of IOS.

Most recent, Plasma ceramic spray is used on parts of tribosystem, has been investigated on the tribological performance. The application of ceramic coatings by plasma spray has become essential in tribosystems to produce better wear resistance and longer life in various conditions. The purpose of this work was to investigate the wear behavior of $8%Y_2O_3-ZrO_2$ coating due to temperatures of post-spay heat treatment. The plasma-sprayed $8%Y_2O_3--Zirconia$ coating was idiscussed to know the relationship between phase transformations and temperatures of post- spray heat treatment. Wear tests was carried out with ball on disk type on normal load of 50N, 70N and 90N under room temperature. The transformation of phase and the value of residual stress were measured by X-ray diffraction method(XRD). Tribological characteristics and wear mechanisms of coatings was observed by SEM. The tribologieal wear performance was discussed a point of view for residual stress. Consequently. post-spray heat treatment plays an important role in decreasing residual stress. Residual stress in coating system has a significant influence on the wear mechanism of coating.

Patients with obstructive sleep apnea (OSA) whose phenotype belongs to a craniofacial vulnerability are referred from sleep doctors to orthodontists. In adults, for osseo-pharyngeal reconstruction (OPR) treatment, permanent maxillomandibular advancement (MMA) surgery and use of a temporary mandibular advancement device (MAD) are applied. This case report demonstrates successful treatment of OSA through application of phased MAD and MMA in a 16-year-old male with craniofacial deformity and residual growth potential. This patient showed skeletal and dentoalveolar changes after 7-year MAD use throughout post-adolescence, which affected the design and timing of subsequent MMA surgery, as well as post-surgical orthodontic strategy. This case report suggests that OPR treatment can be useful for treatment of OSA in post-adolescent patients, from an orthodontic point of view, in close collaboration with sleep doctors for interdisciplinary diagnosis and treatment.

Nowadays, many educational facilities are being renovated. However, due to the absence of a system for post renovation of educational spaces, users are less satisfied with the spaces after the renovation and there is a limit in establishing future directions for improving educational space renovation. From this point of view, this study was conducted to increase the users' satisfaction in renovation space planning of educational spaces and to establish a system for management after renovation. As a specific research method, the space preference of students was used to evaluate the space after renovation. By researching the opinions of the students who use the most educational space, not only the direction of the renovation plan of the future educational space can be given but also the user's opinion can be reflected in the spatial plan in detail. In terms of management of future educational spaces, this study can be used as a basic study for developing post evaluation indicators for renovation of educational facilities.

The welding residual stresses produced by the welding frequently caused a crack and promote stress corrosion etc. in HAZ(heat affected zone) contained with external load and weakness of material. Therefore, PWHT(post welding heat treatment) is widely used to reduce wekdubg residuss, to relax hardening of heat affected zone and to get rid of impurity. In this study, in order to define the effect on shappes of T-welded joint, during the post welding heat treatment, we have carried out numerical analyses on the several test pieces by using computer program which was based on thermal-elasto-plato-plasto-creep theories for the study. The main results obtained form this study is as follows: 1) The mechanical difference for change the thickness of plate and groove angle did not appear. 2) The distribution modes of welding residual stresses are same on the all test specimens during the post welding heat treatment. 3) In a mecharical point of view, minimum groove groove angle($40^{circ}$) is more suitable than maximum groove angle($60^{circ}$). 4) Therefore, it is appropriate to minimize the size of groove shape in strength and safety.

Purpose: The purpose of this study is to find a way to improve and overcome the psychological treatment limited to the negative factors dealt with in psychology from a positive psychological point of view. To this end, this study aims to verify whether a positive psychotherapy program can improve happiness, resilience, and post-traumatic growth along with improvement of psychological symptoms such as depression. Research design, data and methodology: To this end, in this study, mean difference analysis was conducted using t-test on 10 participants in the 16th PPT program and 14 in the control group. Also, after setting the main variables, we tried to confirm the effectiveness through simple regression analysis and multiple regression analysis of the causal relationship model. Results: As a result of the independent sample t-test and the paired sample t-test, it was confirmed that the group participating in the PPT program had higher flourish, happiness, resilience, post-traumatic growth, and lower depression. In addition, as a result of regression analysis, it was confirmed that post-traumatic growth had a positive effect, and that depression was a life-threatening factor. Conclusions: Since the PPT program has a positive effect on the participants with relatively negative psychological symptoms, it is necessary to expand it. In addition, it is necessary to introduce various preventive programs such as PPT as well as traditional psychological treatment for negative symptoms such as depression.
