A public pedestrian passage induces traffic into the apartment complex, and therefore, it requires the application of Crime Prevention Through Environmental Design(CPTED). This paper aims to analyze the conditions and to suggest the improvements of public pedestrian passages in apartment complexes, applying a 3-D approach from CPTED aspect. The first aspect is "Designation": 1)The linkage between the public pedestrian passages is weak, and their designated purpose becomes unclear. 2)When the designated purpose is not considered for each complex, the closure rate is high. 3)The closure rate of the "Through type" is high. It suggests that the pedestrian network should be built and vitalized at the local urban level. The second aspect is "Definition." The public pedestrian passage lacks a social, cultural, and legal definition and only has a passive physical definition. It suggests that a legal definition and specialized guildline be prepared. The third aspect is "Design": 1)Insufficient territoriality exists between the public pedestrian passage and the inside of the complex. Territoriality should be reinforced between the public pedestrian passage and the rest of the internal territory. 2)The landscaping adjacent to the public pedestrian passage lacks deliberation. Since this is where safety and privacy collide, detailed design and maintenance of the landscaping is required. 3)It lacks systematical crime prevention facilities and should compensate accordingly.

Purpose: The purpose of this study was to analyze the space planning of the Senior Center which was supplied recently in apartment complex, to activate the spaces suitable for the changes and needs of the elderly and to explore the complex functions as a community space where intergenerational exchanges are possible. In other words, we sought implications for the physical plan of the district as a community base space and searched for improvement plan. Methods: The survey was conducted by five large private sectors of construction, and 10 of them were built after 2010 in an urban area(Seoul). Literature review, data analysis, field survey and interview were used for the research method. Results: As a result, it was difficult to meet the demands of various elderly people in the space planning, program and operation mode at the current level. In particular, the Baby Boomer generation as an active silver generation will not use the Senior Center. Therefore, based on the results of the survey, we propose some of the following about the Senior Center in apartment complex. First, it is necessary to change the term "the Senior Center" as defined in Article 55-2 of the "Regulations on Housing Construction Standards, etc.". Second, the criteria for setting up the elderly complex space should be presented specifically. Third, it is necessary to secure financial resources in operation and management. Finally, it is necessary to support the residents' organization for community revitalization. Implication: Through the amendment of the laws, it will be possible for various generations to have opportunities to interact by activating the existing community spaces for seniors. It will also contribute to improving the community of apartment complexes.

To enhance the solubility and stability of lansoprazole (LAN), new proton pump inhibitor, we were prepared various molar ratio of inclusion complex with $2-hydroxypropyl-{\beta}-cyclodextrin$ (HPCD) and organic alkali agent, meglumine (MEG). Inclusion complex formation of LAN with HPCD was investigated by Differential Scanning Calorimetry and X-ray diffractometry. The aqueous solubilities of inclusion complexes, and the stabilities of 1:4 and 1:5 inclusion complexes in aqueous solutions containing different concentrations of MEG were examined. The stability of 1:5 LAN-HPCD inclusion complex containing MEG, which was equaled to amount of LAN, was performed in 0.9% NaCl and 5% dextrose solution. The formation of inclusion complex of LAN with HPCD was $A_L$ type and the molar ratio of complex was 1:1. The stability constant was $41.557\;M^{-1}$. As molar ratio of LAN to HPCD was increased, solubility of inclusion complex was increased. 1:5 LAN-HPCD inclusion complex was more stable than 1:4 LAN-HPCD inclusion complex. And as contained MEG amount in LAN solution was increased, stability of 1:4 and 1:5 LAN-HPCD inclusion complexes was improved. Also stability of 1:5 LAN-HPCD-MEG inclusion complex in 0.9% NaCl solution and 5% dextrose solution was similar to it in water at room temperature, but it was unstable at $40^{\circ}C$.

The main purpose of this study is to substantiate the theoretical and methodological foundations of the organizational and economic mechanism of development of the agro-industrial complex in modern conditions. Organizational and economic mechanism is presented as a complex organizational structure of the system type, which is aimed at performing specific functions, the characteristic feature of which is the constant support of process changes without which the organizational and economic mechanism can not exist. There are four components of the agro-industrial complex, represented by agriculture and the national economy, which ensure its operation, including industry, processing of agricultural products, its storage and transportation, sale and repair and maintenance of agricultural machinery and more. It is proved that the organizational and economic mechanism of development of agro-industrial complex in modern conditions it is expedient to consider: from the point of view of system and process approaches; as a set of economic levers and organizational measures to influence the agro-industrial complex; constituent components of organizational influence on the development of the complex; a set of components, elements that are integrated into the system of economic relations of the subjects of the agro-industrial complex; a set of purposeful stimulators of agro-industrial complex development. The functions of the organizational component of the mechanism of agro-industrial complex include: redistributive, planning, interaction, control, integration and regulatory functions, the functions of the economic component include consumer, investment and innovation, social, incentive, monitoring functions of the mechanism. The symbiosis of the functions of organizational and economic components ensure the effectiveness of the organizational and economic mechanism of the organizational and economic mechanism through its functionalities as a whole.

This study was conducted to identify the pollutants generated by the fuel complex and to determine the health effects of the surrounding residents. In addition, based on the results of epidemiological surveys and health impact surveys of local residents, we analyze the distribution of patient groups and exposure characteristics according to the distance from the fuel complex boundary. Samples were collected from the briquette plant within the fuel complex and analyzed by SEM-EDXA, X-ray Fluorescence Spectrometer, and ICP. In addition, the distribution of patients and exposure characteristics were analyzed according to the distance from the fuel complex and yard boundaries. Analysis of briquette samples from the fuel complex showed that the average particle size was 10-30 ㎛, the shape was irregular, and SiO₂ accounted for more than 50%. It is believed that silica, which causes pneumoconiosis, may have been scattered into the air. In particular, there was a large distribution of 5 ㎛ particles that affect respiratory diseases. According to the analysis of the residential addresses and distribution of pneumoconiosis cases, many pneumoconiosis cases were located in the area between 200 and 500 meters from the boundary of the fuel complex. In addition, 28 pneumoconiosis cases were identified as a result of the epidemiological survey and health impact survey at the fuel complex. In detail, there were 8 cases of occupational pneumoconiosis, 6 cases of environmental pneumoconiosis, and 14 cases of occupational and environmental pneumoconiosis. The confirmed pneumoconiosis cases were located between 0.3 and 1.1 kilometers from the fuel complex. It was found that environmental pollutants generated by the fuel complex adversely affect the health of local residents. In particular, there are many cases of pneumoconiosis in the area between 200 and 500 meters from the boundary of the fuel complex, and this distance is considered to be the direct and indirect impact zone of the briquette plant.

This study draws economic expense factors according to the influence of generation resulted from slipstream and the arrangement of the complex when arranging and designing the complex for offshore windpower development as a model of 50MW offshore wind farm and conducts economics analysis. According to the result of the analysis, O (Optimize) arrangement was the one that has the highest generation for having the best windpower resources in terms of design and being least affected by slipstream; however, the arrangement requires expensive submarine cables and high installation cost. Therefore, according to the analysis of economics, it was thought that 50MW complex should have less economics as BC ratio 0.95 than the series arrangement of main wind direction and I+80 series arrangement would be rather more economical. This economics evaluation provides comparison according to the arrangement of the development complex considering the uncertainty of the electricity price and gross construction cost. And it is expected that the result of economics evaluation would greatly differ by installation capacity, and the reason is that the cost of electric infrastructure takes up a higher portion than the gross construction cost of the development complex. The only way to compensate this part is to make the windpower development complex larger. It seems that it will be necessary to enhance spot applicability to evaluate economics afterwards and pay consistent attention to and conduct follow-up research on the economics evaluation of the complex construction.

The Guro Exporting Industrial Complex has become a core of success story of Korean economy in 1960s. Re-examining the making process of Guro Complex, this paper intends to disclose the real and fictional aspects of this myth. For this purpose, this study tries to inquire into this process which is divided as dimensions of conception, execution and evaluation from a view of political sociology. Its results are as follows: The making of Guro Complex was not propelled by the state unilaterally, but passed through the process of conflicts and conciliations among various social forces such as state, business groups and local communities etc. As this complex was built on the basis of state's full supports, it is difficult to conclude it as a case of 'parasitic industrialization'. And in spite of its ostensible success, it is difficult to evaluate that its original goal which means a building of the bonded exporting complex with Japanese Koreans' investment was accomplished. Therefore it is needed to discover its whole aspect from the comprehensive perspective, not to be enchanted by its official results.

We firstly present the unified Far-UV continuum map of the Taurus-Auriga-Perseus (TPA) complex, one of the largest local associations of dark cloud located in (l, b)=([154,180], [-28, -2]), by merging both FIMS and GALEX. The FUV continuum map shows that dust extinction correlate well with the FUV around the complex. It shows strong absorption in FUV toward the dense Taurus cloud while it does not in California cloud. It turned out that it is related to the relative location of each cloud and Perseus OB2 association. We also present some results of dust scattering simulation based on Monte Carlo Radiative Transfer technique (MCRT). Through this dust scattering simulation, we have derived the scattering parameter for this region, albedo(a)=$0.42^{+0.05}{_{-0.05}}$, asymmetry factor(g)=$0.47^{+0.11}{_{-0.27}}$. The optical parameters we obtained seem reasonable compared to the theoretical model values ~0.40 and ~0.65 for the albedo and the phase function though the phase function is rather small. Using the result of simulation, we figured out the geometries of each cloud in the complex region, especially their distances and thicknesses. Our predictions from the results are in good agreement with the previous studies related to the TPA complex. For example, the Taurus cloud is within ~200pc from the Sun and the Perseus seems to be multi-layered, at least two. The California cloud is more distant than the other cloud on average at ~350 pc and Auriga cloud seems to be between the Taurus cloud and the eastern end of the California cloud. We figured out that across the TPA complex region, there might be some correlation between the LSR velocity and the distance to each cloud in the complex.

Over 30% of domestic soil contamination has occurred via petroleum products and complex oil. Moreover, contamination by complex oil is more intense than it is by a single petroleum product species. In this study, we analyzed sectional TPH (total petroleum hydrocarbon) pattern and sectional ratio of current domestically distributed petroleum products, such as kerosene, diesel, bunker C, and lubricant and complex oils, to determine pollution characteristics of the soil. In the TPH pattern, kerosene, which is a light distillate, had an early retention time, and lubricant oil, which is a heavy distillate, had a late retention time in the gas chromatogram. In addition, we obtained a complexly contaminated soil via diesel and lubricant oil from the Navy and inspected it for its ratio of complex oil species. The inspection results showed that this soil was contaminated with 85% diesel and 15% lubricant oil. The method developed in this study could be used to determine complex petroleum sources and ratios at sites with accidentally contaminated soil.

The relation between the vibration induced from machinery and the radiated sound is complicated. Acoustic intensity method is widely used to obtain the accuracy of noise measurement and noise identification. In this study, as groundwork, the complex acoustic intensity method is performed to identify noise source and transmission path on different free space point source fields. As an industrial application, the complex acoustic intensity method is applied to HVAC to identify sound radiation characteristics in the near field. Experimental complex acoustic intensity method was applied to HVAC, it is possible to identify noise sources in complicated sound field characteristics which noise sources are related with each other, and certificate the validity of complex acoustic intensity. Especially, it can be seen that complex acoustic intensity method using both of active and reactive intensity is vital in devising a strategy for identification of noise. Also, the vector flow of acoustic intensity was investigated to identify sound intensity distributions and energy flow in the near field of HVAC.
