The purpose of this paper is to identify woodblocks which were engraved in the providences in the mid Chosun dynasty, especially ones engraved under the auspices of Yu Heui-chun(柳希春), but not listed in $\boxDr$Kosachwalyo 攷事撮要$\boxUl$. This could be done by the analyzing $\boxDr$The Diary of Miam 眉巖日記$\boxUl$ written by Yu Heui-chun. It is a book which recorded daily life of eminent scholar and official covering political, social and cultural aspects, books and family matters. There were two categories of books published under the auspices of Yu Heui-chun. One is the books written by his grandfather in law, Choi Bu(崔溥), which were $\boxDr$Keumnamjip 錦南集$\boxUl$ collective works of Choi Bu, and $\boxDr$Pyohaerog 漂海錄$\boxUl$, essays on travelling across China. The other is the books for children, $\boxDr$Sinjeung Yuhap 新增類合$\boxUl$ for teaching characters and $\boxDr$Sog Mong-gu 續蒙求$\boxUl$ for moral education. These woodblocks have to enlisted in the woodblock catalogs. The analysis shows that most of these woodblocks by Yu Heui-chun were not recorded in either of two $\boxDr$Kosachwalyo 攷事撮要$\boxUl$ editions published in 1575 and 1585. In this respect, $\boxDr$The Diary of Miam$\boxUl$ proved itself to be of great significance in terms of bibliography studies.

This study was measured weight loss, total ascorbic acid, titratable acidity, soluble solids content and overall appearances to investigate the effect of corrugated fiberboard box coated with functional materials ; R, G, X box, R, G and X box and Con(double wall corrugated fiberboard) box during storage at $25^{\circ}C$. Weight loss of mandarin of control, corrugated paperboard box coated with functional materials(Y-, R-, G-box) after 8 days were 2.56% to 3.67%. There was not different to weight loss among the four kind of packages. Titratable acidity and soluble solids content of packages was not significant. Total ascorbic acid content(TAA) of mandarin packed with R-box and Y-box was 10% higher than that of control after 8 days. Decay ratio of R-box, Y-box, G-box and control was 4%, 10%, 10% and 8%, respectively. Overall appearance of R-box was the best.

In pressure cooling system, produce were packed in vented box and cooled rapidly by producing a difference in air pressure on opposite faces of stacks of vented box. So, energy requirements and performance of pressure cooling system depended upon the air flow rate and the static pressure drop through packed produce in vented box. The static pressure drop across packed produce in vented box normally depended upon air flow rate, vent area of box and conditions of produce bed (depth, porosity, stacking patterns, size and shape of products) in box. The objectives of this study were to investigate the effect of vent area and air flow rate on airflow resistance of empty box and packed produce in vented box, and to investigate the relationship between the air flow resistance of packed products in vented box and sum of air flow resistance of empty box only and products in bulk only. Mandarins and tomatoes were used in the experiment. The airflow rate were in the range of 0.02~1.0$m^3$/s.$m^2$, the opening ratio of vent hole were in the range of 2.5~20% of the side area. The results were summerized as follows. 1. The pressure drops across vented box increased in proportion to superficial air velocity and decreased in proportion to opening ratio of vent hole. A regression equation to calculate airflow resistance of vented box was derived as a function of superficial air velocity and opening ratio of vent hole. 2. The pressure drops across packed produce in vented box increased in proportion to superficial air velocity and decreased in proportion to opening ratio of vent hole. 3. Because of the air velocity increase in the vicinity of vent hole in box, the airflow resistances of packed products in vented box were always higher than sum of air flow resistance of empty box only and products in bulk only. 4. Based on the airflow resistance of empty box and products in bulk, a regression equation to calculate airflow resistance of packed products in vented box was derived.

To increase the night use level, this study was analyzed perception of users about the public safety, and extracted main variables which were influencing public safety. The public safety was evaluated by the actual (on site) and nonactual users (off site) and the Delphi method. The night users of female and the elders were relatively more than male and the young respectively as compared with day. Walking was predominant in approaching means. In public safety ratings, $\boxDr$vuknerability to violence$\boxUl$varied accoding to sex, income, education, marriage, job, age. $\boxDr$crowding, $\boxDr$noise$\boxUl$ were important variables in satisfying users at night. $\boxDr$Lack of surveillance, $\boxDr$harassment of other person$\boxUl$, $\boxDr$rowdy behavior in poorer visibility$\boxUl$, $\boxDr$fear in lower intensity of light$\boxUl$ and $\boxDr$vulnerability to violence$\boxUl$stood high , so it is required guarantee of security guard to enhance the park use at night Although the ratings between field and indoor evaluation were somewhat different the variables had so similiar rant.

A blind box is a kind of sales method in that you can only get the product information by opening the package. In 2019, blind box products began to grow rapidly in the Chinese market, and gradually formed a special "blind box economy". The particularity of blind box products is that driven by consumers' curiosity, consumers' purchasing behavior can be directly induced by the visual and tactile perception of commodity packaging. Therefore, it is necessary to explore the psychological needs of consumers and master the blind box packaging design elements under the influence of consumer psychology. This paper takes figurine blind box packaging elements as the research scope and Chinese blind box consumers as the research object. Through market research and literature study, We are designed to conduct a questionnaire survey and SPSS empirical study to find out the differences in the preferences of different consumer temperament types for blind box packaging, taking the characteristics of blind box products and consumer psychology as the relevant theoretical background. The research results show that among the blind box consumers, choleric type consumers predominate, the color of the blind box packaging presents red, orange, and yellow preference, and the material presents metal, and plastic preference. The shape of the blind box shows a preference for special shape.

In case of wood flooring, the high emissivity would be one of the most important properties especially as the cover material of underfloor heating system. The FIR (Far Infrared) materials such as wood emit FIR energy by heating, which has been used as the medical therapy such as dry sauna. This research investigated the emissivity and the emission power of wood composites by comparing the amount of the three heat transfer modes transferred by infrared radiation which came from the increased temperature of the bottom board of the plywood box by the heater. The results showed the value of radiation mode was the highest mode for the plywood box, and the convection mode was the main mode for the aluminum box. The rate of convection was 81.8% in the aluminum box and 48.2% in the plywood box, respectively. In case of the rate of radiation, the aluminum box showed only 15.4% and the plywood box showed 51%. The emissivity and the emission power of birch plywood showed the same values as those of wood. The amount of energy required for the temperature rising of water within vial in the aluminum box and in the plywood box were 3.32 kJ and 6.70 kJ respectively, which showed that the vial temperature of the plywood box was two times higher than that of the aluminum box.

We know the several construction methods for underwater tunnel, but properly submerged concrete box type tunnel was mostly good structure stability and mostly shot length of tunnels. Submerged box type tunnel was buildup the unit segments in dry dock or ship yard by 10 to 20meters. The submerged box was composed with segments was join each together. It was installing the gate and waterproofing the coupling the front hull of a box. The complete submerged box rise up to the surface water, tow in the submerged box by tugboat, going to the destination of tunnel construction site. Beforehand dredge up soil at the bottom of a underwater, sinking the submerged box, connection together complete submerged box in underwater. The research and development ILM tunneling method is receiving careful study. Biggest weakness in submerged concrete box type tunnel was pressure waterproofing, box to box connecting, complete submerged boxes navigation and installation, after operation the submerged tunnel and management concrete box structure. It was positive evidence in submerged concrete box type tunnel. We make a practical application of the principle "the ILM tunneling method in underwater construction methods."

In Korea, Jeongho Kim is the most noted scholar who studied on a map and a topography during the 19th century. He arranged the merit and the defect of the former maps systematically through such studies and made Cheonggudo(‘do’ means an atlas) in 1834. Accordingly, it reflected the result of many scholars's efforts to make accurate a complete map of Joseon. Especially, it referred to Haedongyeojido which had been made during 1776-1787. Of course, Haedongyeojido also referred to Joseonjido which had been made by Gyeongjun Sin(1712-1781) in 1770. Jeongho Kim did not copy Haedongyeojido as it was but edited it newly.
