China has been pursuing continuous education reforms in order to complement the shortcomings of traditional education and to prepare for a new era in accordance with the development of the economy and society. School facilities were rapidly increased due to rapid population growth in the 60s and 70s, but the quality of the school facilities was low considering the efficiency and economy, and the regional variation was serious. The National Standard for School Design was enacted in 1986. Since then, we have proposed a new national standard in 2011 in accordance with social change and educational needs, and it has reached the present time. The purpose of this study is to analyze the main contents of "Code for design of school(GB50099-2011)" which is a standard study for Chinese school design as a basic study to understand changes in school architecture in China.

In Korea, global warming caused by the climate changes impacted on weather system with increase in frequency and intensity of precipitation, and the rainfall pattern changes significantly by regional groups. Furthermore, it is expected that the regional and annual fluctuation ranges of the rainfall in the future would be more severe. Nowadays, agricultural drainage system designed by the existing standard of 20-year return period and 2 days of fixation time cannot deal with the increment rainfall such as localized heavy rain and local torrential rainfalls. Therefore, it is required to reinforce the standard of the drainage system in order to reduce the agricultural flood damage brought by unusual weather. In addition, it is needed to improve the standard of agricultural drainage design in order to cultivate farm products in paddy fields as facility vegetable cultivation and up-land field crop have been damaged by the moisture injury and flooding. In order to prepare for the changes of rainfall pattern due to climate changes and improve the agricultural drainage design standards by the increase of cultivating farm products, the purpose of this study is to examine the impact of climate changes, the changes of relative design standard, and the analytic situation of agricultural flood damages, to consider the drainage design standard revision, and finally to prepare for enhanced agricultural drainage design standards.

The IMO manoeuvrability standard was established for preventing sea accidents such as collisions and strandings due to the lack of manoeuvrability. The standard of ship manoeuvrability enforced by resolution MSC.l37(76) has been applied to vessels of 100m or more in length and all chemical tankers and gas carriers regardless of the length, which were constructed on or after 1 July 1994. The IMO manoeuvrability standard is able to be divided into three kinds as followings; (1) Turning capability standard: Estimated values in design stage are to be certified by turning circle test of the actual vessel. (2) Course keeping quality standard : Estimated values in design stage are to be certified by 10 deg. and 20 deg. zig-zag tests of the actual vessel. (3) Shortest stopping distance standard : Estimated value in design stage is to be certified by the shortest stopping distance tested by the actual vessel. In this paper, the authors verified the criteria of IMO manoeuvrability standard comparing them with the values resulted from sea trial tests of various kinds of actual vessels and examined separately the validity of all criteria of the standard.

The Standard for BIM in Construction of China was released in 2017. The Unified Standard for BIM of China also took effects on 2017. The BIM standards of China needs to be compared with those related guidelines of Korea to find the status and characteristics for future development of BIM application in both countries' construction industries. The research methodology is a case study of comparing various standards of both countries. The case study results reveals many interesting issues for future BIM application and guidelines for practice of design and construction process. The research foundings include followings : LOD (Level of development) are well defined including LOD 350 in Chinese Standard. P-BIM(Practice based BIM) concepts and series of standards are set for the well-defined design and construction process by work stage in China. Korean standards shows more processes of design and documentation in detail. Major three aspects, particularity in BIM standard by work trade, practicality in BIM work process of design and construction, and professionality in subjects of BIM application, are analyzed and compared with various Guidelines of BIM in both countries.

The purpose of this study is to provide the improvement idea for an school uniform styling that better satisfies female high school students' changing demands, through evaluating images differences according to design variation in school uniforms. This study was carried out with a between-subject design by using the stimulant materials of school uniform design and image assessment scale. The stimulant materials used for this study were 27 designs with blazer/skirt ensemble and 21 designs with vest/skirt ensemble. The survey materials were collected through a questionnaire from a total of 192 female high school students living in Gyeongsangnam-do. As a result of analyses on a image of blazer/skirt ensembles, 4 factors were extracted such as neatness, uniqueness, activeness, and attractiveness. Blazer was the only variables that exerted significant effects on neatness, uniqueness, and attractiveness. As a result of analyses on a image of vest/skirt ensembles, 4 factors were extracted such as attractiveness, neatness, uniqueness, and activeness. Skirt was the only variables that exerted significant effects on attractiveness, neatness, and uniqueness. Neat image was perceived to be high in ensembles of standard blazer/standard collar/horizontal-seam skirt, standard vest/skirt with horizontal color combination, and buttons-down vest/horizontal-seam skirt. Unique image was perceived to be high in ensembles of blazer with bindings/standard collar/solid skirt, and vest with pockets/skirt with vertical bindings. Also, active image was perceived to be high in ensembles of vest with pockets/skirt with vertical bindings, and buttons-down vest/skirt with vertical bindings. Attractive image was perceived to be high in ensembles of blazer with bindings/peaked lapel/skirt with vertical bindings, and standard vest/horizontal-seam skirt. In conclusion, this study reveals that different items and pieces of school uniforms can be combined in many different ways to create quite diverse looks. Thus, this study provides important basic data for research on teenagers' fashion and clothing.

On September 12, 2016, Gyeongju earthquake occurred. Its local magnitude was announced to be $M_L=5.8$ by Korea Meteorological Administration (KMA). Ground motion data recorded at KMA, EMC and KERC stations was obtained from their data bases. From the data, horizontal and vertical response spectra, and V/H ratio were calculated. The horizontal spectrum was defined as geometric mean spectrum, GMRotI50. From the statistical analysis of the geometric mean spectra, a mean plus one standard deviation spectrum in lognormal distribution is obtained. Regression analysis is performed on this curve to determine the shape of spectrum including transition periods. Applying the same procedure, the shape and transition periods of vertical spectrum was obtained. These results were compared with the Korean standard design spectra, which were developed from domestic and overseas intraplate earthquake records. The response spectra of Gyeongju earthquake were found to be almost identical with the newly proposed design spectra. Even the V/H ratios showed good agreement. These results confirmed that the method adopted when developing the standard design spectra were valid and the developed design spectra were reliable.
