In this study, we divided the portraits in the reign of King Seonjo into those which were created before and after the Japanese invasion. We then examined various aspect of costumes expressed in the portraits of meritorious vassals. To analyze official uniforms (Heuk-Danryeung), we examined the Samo height; the side wings' type and pattern; the Danryeung pattern; the Mu style; the processing method of lateral lines in Danryeung the rank badge and rank belt, the color of Dabho and Cheolrik, which were undergarment of Danryeung and Heuk-wa. The meritorious vassals' portraits, prior to Imran, were analyzed with a portrait of Han Eung-in, a Gwang-kuk Pyeong-nan meritorious vassals. The Samo was the highest of the Choson dynasties, and the cloud and treasure pattern was identified on the side wings. The Heuk-Danryeung was a dark blue(acheongsaeg) Danryeung of manja-shaped cloud patterns with a large outward wrinkled Mu, and it had a wild goose badge (second rank) and a Sabgeumdae. It did not coincide with the Pumgye(Jaheondaebu) recorded in Gugjo-inmulgo. Reddish Dabho for Dangsang-kwan, green Cheolrik which was undergarment of Danryeung, and Heuk-wa. were identified. After the invasion of Japan, portraits of Hoseong, Seonmu, and Cheong-nan meritorious vassals were analyzed through eighteen portraits, including Lee Hyeon-bok. After the invasion of the Japanese, the height of the Samo's top was much lower and the width of the side wings was wider than before the invasion of Japanese. The Heuk-Danryeung was a dark blue (acheongsaeg) Danryeung of manja-shaped cloud patterns with a stretching backward Mu. Rank badge and rank belts were almost identical with the record, but there were two exceptions (Sin-jab and Kim, Sae-sin). Therefore, it was reaffirmed that the meritorious vassals' portraits were drawn by the Pumgye at the time of appointment. Among the undergarments of Heuk-Danryeung, green Dabho(11), blue Dabho(4), reddish Dabho(3), and blue Cheolrik(10), green Cheolrik(6), reddish Cheolrik(1), and yucheongsaeg Cheolrik(1) were identified, However, it is suggested that the Dabho of Hoseong, Seonmu, and Cheong-nan meritorious vassals should be the reddish Dabho of Dangsang-kwan, which is the same as the previous Imran, and a green Cheolrik.

As a part of study examining Korean costume remaining in Yanbian China, this study explored changes in ceremonial clothing for marriage worn by Korean(Chosun race) in Yanbian China. About one hundred years ago, Koreans moved to Yanbian China and had worn traditional clothing for marriage ceremony until before 1940. Data were collected by true interview and field observation while staying in that area. Samo and Dalyung for bridegrooms, Wonsam and Jockdoory for bridegrooms, wonsam and Jockdoory for brides were usual costume for wedding ceremony, however, for couples in inferior conditions of life, Bazy and Jeogory for bridegrooms, yellow Jeogory and red Chima for brides were accepted for ceremonial costume. As western culture came to this area in about 1940, bridegrooms wore western style suit, while brides dress in white Chima, Jeogory and Neowool. To date, Korean brides have worn traditional Chima and Jeogory for marriage ceremony though slight change has occurred in clothing material and in the forms of Chima, Geogory and Neowool. As the pratice reflected the fact that Korean in Yanbian China as established and sustained traditional China as established and sustained traditional costume and Korean identity even in hush socio-cultural environment.

The paper presents the state-of-the-art in aerodynamic performance of the modern horizontal axis wind turbine. The study examines the different complexities involved with wind turbine blade aerodynamic performance in open atmosphere and turbine wakes, and highlights the issues which require further investigations. Additionally, the latest concept of smart blades and frequently used wind turbine design analysis tools have also been discussed. The investigation made through this literature survey shows significant progress towards wind turbine aerodynamic performance improvements in general. However, still there are several parameters whose behavior and specific role in regulating the performance of the blades is yet to be elucidated clearly; in particular, the wind turbulence, rotational effects, coupled effect of turbulence and rotation, extreme wind events, formation and life time of the wakes.

This study firstly identify the characteristics of the clothes for traditional wedding ceremony from the late Chosun Dynasty (19th Century) and today through comparison. It also tries to discover what today's people are incorrectly aware of regarding the traditional wedding clothes particularly by survey. It ultimately aims to present constructive ways of solution against the illadvised and simplified deformation of the traditional wedding clothes. When comparing the traditional wedding clothes from the late Chosun and its modern counterparts, Dan-ryung and Samo-kwandae is still used for bridegroom's dress. In case of bride's dress, several items such as Yeom-eui, So-eui and Hwal-ot have been disappeared while Won-sam can be seen today. There were found many additional differences not only in type of the wedding clothes, but also in its form and constitution. Therefore, it is advisory to take the wedding clothes worn by commoners and upper class as the basic form for today's traditional wedding clothes. In addition, diversified research should be carried on to make them broadly accepted by today's life.

The purpose of this study was to determine the present air pollutant concentrations and predicted levels for next 30 years in urban environment of Karachi city. For that, a total of fifty measurements were made for each twenty selected locations of the city. The locations were selected on the basis of land use pattern such as residential, commercial, industrial settlements, open areas, congested traffic and low traffic areas for investigation of air pollutants variability and intensity. The measurements were taken continuously for six months period using PM Meter, Model AEROCET 531 and Ambient Air Quality Meter, Model AAQ 7545. The concentration of air pollutants were found higher at Al Asif Square and Maripur Road due to higher intensity of traffic and at Korangi Crossing because of industrial areas. The level of pollutants was lower at Sea View owing to lower traffic congestion and transportation of pollutants by sea breezes.

For survival of human beings clean water is an essential commodity whereas contamination in drinking water threatens to mankind. The main cause of water contamination is social and development activities of human being along with increasing population. The community in the study area has acute shortage of drinking water along with about 40 to 60% has no access to safe drinking water. This study indicates drinking water quality of two major sources of coastal belt of Karachi one is supplied by Karachi Water & Sewerage Board (KWSB) as tap water and the other through groundwater. The physicochemical analysis was carried out by following the standard methods for checking the quality of drinking water. The analyzed results showed that the quality of groundwater was unfit as potable water. The most critical situation was observed as high level of contamination followed by high turbidity and increased salinity levels. TDS in surface water were found 12% above and TDS in groundwater was 20% below the National Drinking Water Quality Standards (NDWQS) of Pakistan as well as the permissible WHO drinking water quality guidelines.

This paper is about the dress styles during the 16th century of the Chosun dynasty, just before the Japanese Invasion of Korea in 1592, through painting-Kiyeonghoido. In the Chosun period, dress styles played an important role in representing the differences in social status. The most remarkable signs of social standing are the hair ornaments. Officials in ranks, noksas, and seoris are wearing a same, a yugakpyeongjeongeon and a mugakpyeongjeongeon respectively. The head ornament for musicians in high ranks is a samo, and, for those in low ranks a hood or a heuklip. Accordingly, head ornaments were important articles among apparels, and especially ripja was an article that sensitively reflected the contemporary fashion. Such a trend also influenced the common people's styles of dress. Thus, the style of the heuklip worn by the chamberlain in Kiyeonghoido resembled of yangban's. Actual official uniforms also diverged from the specifications for them. Sangboks were red for both dangsanggwans and danghagwans, but their ranks were marked by the material of their dress rather than by the breast plates. Dress styles change over time as the society members influence and are influenced by each other. Therefore, owing to the social characteristics of a hierarchical society, dress styles are distinctive according to the wearers' social standings and roles, and various dress styles emerge that deviate from regulations. The significance of the present paper is to review the diversity of the dress styles during the 16th century of the Chosun dynasty.

The operation of a Doppler wind LIDAR in a mobile environment is very sensitive to shocks and vibrations, which can cause critical failures such as misalignment of the optical path and damage to optical components. To be able to stabilize the LIDAR and to perform wind field measurements in motion, a shock absorption and vibration isolation system was designed and implemented. The performance of the vehicle-mounted Doppler wind LIDAR was tested in motion, first in a circular test route with a diameter of about 30 m and later in regular expressway traffic. The vibration isolation efficiency of the system was found to be higher than 82% in the main vibration area and shock dynamic deflection was smaller than maximal deflection of the isolator. The stability of the laser locking frequency in the same mobile environment before and after the vibration isolation system installation was also found to be greatly improved. The reliability of the vibration isolation system was confirmed by good results of the analysis of the LIDAR data, in particular the plane position indicator of the line of sight velocity and the wind profile.
