This study explores the causes and processes of morphological transformation of apartment complexes in Busan. All apartment complexes built until the year 2016 were selected for statistical analysis, drawing/map examination, field observation, selected expert interviews based on 6 periodical groups: Period I(~1990), Period II(1991~1995), Period III(1996~2000), Period IV(2001~2005), Period V(2006~2010), and Period VI(2011~2016). The research argues for three 'arrangement' types, P1U, L1U and P2U, which have dominated the whole periods occupying 88% of the total 260 complexes. The switch of the leading type represents for morphological transformation of apartment complexes. Four aspects, density(F.A.R.), height(maximum number of floors), deformed-building-type ratio, and building-orientation, have affected the change of 'arrangement' types. Density was the major cause of the arrangement-type switch, from P1U to L1U, on Period II(1991~1995). The morphological change, from type L1U to P2U, on Period V(2006~2010) was caused by height and orientation, and is correlated with the increased number of deformed-type buildings. The first phase morphological change on Period II(1991~1995) was resulted by the supply side of apartment. However, the second phase transformation on Period V(2006~2010) had gone through the complex process including reflection of consumers' demands. The significance of research is to reveal the morphological transformation process of apartment complexes through analytical investigation of the entire apartment data in Busan. The result shows that the major change of urban paysage started to occur from Period V(2006~2010), and the superficial evaluation on apartment 'being monotonous and repetitive' may not be proper at least from the perspective of town plan.

Purpose - Loading can decrease the productivity due to the possibility of carrying out with the opposite order of storage in container terminal. When the container is to be taken out, it is needed to move the container stacked upon the container to be carried out to other place temporarily. It is called as rehandling. Remarshalling, with the loading plan, is the arranging the containers before the ship arrives in order to avoid the rehandling during the carrying out. The present study tried to find out the factors affecting the efficiency when building the remarshalling plan with the utilization of neighboring storage space as a outer slot, and analyzed the efficiency of several remarshalling algorithms with the combination of those factors. Research design, data and methodology - The present study used, when the remarshalling plan is prepared for utilizing the outer slot, the simulation methods in order to compare the efficiency of the remarshalling algorithms which made with the factors affecting the efficiency. The factors affecting the efficiency are the method of making the child node, method of arrangement, and possibility of application of FIX. In order to analyze the affecting factors on the efficiency, several algorithms are prepared with the combination of production of the child node and the arrangement method with the availability of FIX application. With this algorithm, the effect of the factors on the efficiency after building up of remarshalling plan with the target on the bay with 10 rows, 8 columns, and 10 indices. Results - The method of rearrangement and making of a child node as the factor affecting the efficiency of remarshalling utilization of the outer bay were studied. It is efficient to combine the method of making a child node with MCS in order to reduce the number of moving the containers. For reducing the time in carrying out, it was found that all arrangement methods should be combined with RCS for the efficiency. The result of experiment shows the application of FIX with good result in case of succession ratio. In addition, when FIX was not applied, all of the most combinations resulted in short time in remarshalling. As a result, it can be concluded that the algorithm with proper combination of making the child node and the arrangement can increase the job efficiency based on the importance. Conclusion - The present study suggested and analyzed the algorithms with the combination of the arrangement method, the making of child node, and FIX. It is needed to develop the algorithm to judge the possibility whether the best remarshalling plan can be built or not within the bay in order to find a better method between the two cases such as within the bay and outer the bay. As a method for extending the study on the factors affecting the efficiency, it is possible to find out the way to build the remarshalling plan within the permitted time under any storage situation.

In Sasang constitutional medicine, I have researched the process of visceral structure in the Eight Constitutionals under circulation of the five elements and the formation of primary source of illness. From this research, I could draw following conclusions through combination of the auxiliary psycho-formulas by applying the constitutional acupuncture therapy on the five elements diagnostic calculation. Since the arrangement for the five dimensions of organs in the eight constitutions has been formulated by circulation of the five elements in Sasang constitutions, if the five elements begin circulating count-clockwise from the reference point at the organs in Sasang constitutional medicine, the positive constitutional arrangement of organs is built up such as, the positive constitution of metal, earth, wood and water, while begin circulating clockwise, the negative constitutional arrangement of organs is formulated, such as the negative constitutions of metal, earth, wood and water. The source of illness results from imbalance of the organic force being generated by transfer of the five elements from compatibility to incompatibility when the five elements circulate. Hence, it has been acknowledged that if the source of illness comes from the strongest organ, it is the time when circulation of the five elements progresses from the second organ (the second strongest) in incompatibility, and if the source of illness comes from the weakest organ, it is the time when circulation of the five elements progresses from the third organ (the middle) in incompatibility. It is considered proper to diagnose meridians of the pericardium and the Triple Burners rather than to diagnose meridians of the heart and the small intestine which forms the visceral arrangement of the eight constitutions. For instance, the auxiliary psycho-formula obtains its prescription by attenuating the first organ (the strongest) while augmenting the fourth organ (the second weakest) when the axis of incompatibility in the five elements circulation crosses the second and the third organs, and it gets its prescription by attenuating the second organ(the second strongest) while augmenting the fifth organ(the weakest) when the axis of incompatibility in the five elements circulation crosses the third and the fourth organs. In addition, when medicating, the $4{\sim}5$ times of repeated performance can be assumed to represent the amount of an energy that each organ bears depending on the phase in the arrangement of the eight constitutional organs.

Alberti's De re aedificatoria is the earliest case in the history of Italian Renaissance architectural treatises dealing with recovery of antiquity through textual and archaeological pursuits. The key source of the Renaissance theoreticians was Vitruvius' De architectura. However, Alberti was keenly aware of inaccuracy and Hellenization of Latinity in this classical text, and tried to compensate them in his own treatise. Furthermore he claimed a reformed discipline of the architects as well as the patrons, and prescribed how future buildings and cities should be built, based on the proper authority of ancient architecture in proper and intelligible Latin. Such an adaptation of classical usage in order to reestablish a modern norm preceded in his earlier work Momus, a satire on the contemporary Italian society of his own by following the model of Lucian. Alberti's suggestion of proper government in Momus's phrase was expanded in De re aedificatoria, for he consider the buildings are subject to the rules of morality and public interests. He proclaimed that the nature of beauty is the reasoned harmony of every part within a body, and architectural beauty also lies on the harmonized arrangement of all the elements within an individual building and of all individual buildings and facilities within a city. For the architects to execute this task, he formulated the concept of lineanenta, the form derived from the mind in order to prescribe the proper place, numbers, scale, and orders for whole building structure. It is the future oriented city-plans and building designs to serve the public interest and the good of all the individual citizens who make up the City-State that Alberti pursued in his treatise.

The objective of this research is to suggest the appropriate natural environment conservation facility management plan in Korea through development of the proper definition and categorization. Bearing the above objective, this study employs the comparison and analysis between domestic and international case studies. Furthermore, several survey methods have been adopted as check-lists for the evaluation of the sample sites and quantitative interviews with government officials and visitors to investigate their perspectives. On the consequence, firstly it was found that considering ecological types and objectives, the proper applicability of natural environment conservation facility could be disaggregated into three types of eco-park, eco-experience and education, and eco-observation facility. Secondly, based on the interview results, the necessity of provision of the natural environment conservation facilities was strongly found among the governmental officials and the residents groups who also expect the expansion of the facilities. Lastly, it appears necessary that the expansion of supporting projects and programs on the natural environment conservation facilities, the estimation and provision of the appropriate funding for monitoring, management and operation, the arrangement of resident experts, and activation of the nature environment education programs.

The soft palate of carcinoma limited to the uvular region is infrequent among oropharyngeal cancers. The oropharynx regulates swallowing and speech through dynamic motions. Failure to reconstruct after surgical resection of the oropharynx structure can lead to permanent velopharyngeal insufficiency. Therefore, suitable reconstruction is important in establishing proper functional outcomes while maintaining oncological safety. We present a case of a 66-year-old male who was diagnosed with oropharynx cancer limited in the uvula accompanied by lymph node metastasis. After surgical resection, reconstruction was performed with the united arrangement of bilateral palatal mucomuscular flap and superiorly based posterior pharyngeal flap. There was no aspiration or reflux after feeding and epithelialization completely occurred after 1 month postoperatively. We report a successful case that the reconstruction with the local flap described above could preserve proper oropharyngeal function after primary surgery in small-sized oropharyngeal cancer.

Tidal farm is a multi-arrayed turbine system for utilizing tidal stream energy. For horizontal-axis turbine(HAT) system, it is recommended that each unit has to be deployed far apart in order to avoid hydrodynamic interference among turbines, as proposed by the European Marine Energy Centre(EMEC). But there is no rule for the arrangement of vertical-axis turbine(VAT) yet. Moreover it has been reported that a proper arrangement of adjacent turbines can enhance the overall efficiency even greater than an arrangement without mutual interference effect. This paper suggests the layout of VATs showing the better performances, which turned out to be quite different from HATs' arrangement. Numerical calculations were performed to investigate the performance variation in terms of the rotational direction as well as the distance between turbines. It has been shown that the best combination of rotational direction and distance between turbines can increase its performance higher about 9.2% than that of two independently operated turbines. It is likely that such improvement is due to the increased velocity between adjacent turbines. For diagonally arranged turbines, the maximum normalized mean power coefficient was obtained to be higher about 5.6% than that of two independent turbines. It is expected that the present results can be utilized for conceptual design of tidal farm to harness the tidal stream energy.

We propose an efficient digital IF down converter architecture for dual-mode WCDMA/cdma2000 based on the concept of software defined radio. Multi-rate digital filters and fractional frequency conversion techniques are adopted to implement the front end of a dual-mode receiver for WCDMA and cdma2000. A sub-sampled digital IF stage was proposed to support both WCDMA and cdma2000 while lowering the sampling frequency. Use of a CIC filter and ISOP filter combined with proper arrangement of multi-rate filters and common filter blocks resulted in optimized hardware implementation of the front end block in 292k logic gates.

This study numerically investigates thermal comfort in a space cooled by the floor-supply air conditioning system, in which three different supply-return locations, one floor supply-ceiling return and two floor supply-floor returns, are treated. A complementary experiment is peformed to validate the present numerical analysis, and the prediction agrees favorably with the measured data. In the numerical procedure, a simplified model mimicking the inlet flow through the diffuser is developed for efficient simulations. The calculated results show that the ceiling return type is far better in thermal comfort than the floor return ones within the extent of this study, which seems to be caused by effective vertical penetration of the supply air against natural convection. It is also revealed that the arrangement of port locations in the floor supply-floor return system has insignificant effect on the cooling performance. For selecting a proper system, other characteristics including the heating performance should be accounted for simultaneously with the present estimation.
