Diabetes is a common disease today, and there are also many cases of developing into serious complications called Diabetic Foot Ulcers(DFU). Diagnosis and prevention of DFU in advance is an important task, and this paper proposes the method. Based on existing studies introduced in the paper, it can be seen that foot pressure and temperature information are deeply correlated with DFU. Introduce the process and architecture of SmarTinsole, an IoT device that measures these indicators. Also, the paper describes the preprocessing process for AI-based diagnosis of DFU. Through the comparison of the measured pressure graph and the actual human step distribution, it presents the results that multiple information collected in real-time from SmarTinsole are more efficient and reliable than the previous study.

Tricholoma gigantium, an edible mushroom, belongs to Tricholomataceae of Tricholoma and is distributed at Jeju-Do in Korea. It is also well-known as the medicinal mushroom in Taiwan. The cultivation method using the compost was developed in Korea in 1995. To develop a mass cultivation method and a superior strain, four strains were collected and tested. To establish the optimal cultivation conditions, various examinations were accomplished. Bag cultivation was more effective than box cultivation and the optimal relative humidity was more than 80%. Although the mycelial growth was tested in the substrate supplemented with different additives, such as rice bran and wheat bran, there's no significant difference between them. It suggested that the environmental conditions were more important than the substrate additives for cultivation.

야경사진은 자연광 일색인 일상의 낮과는 달리 인공광과 자연광이 함께 어우러져 있는 밤의 풍경을 표현한다. 특히, 야경사진은 빛을 어떻게 효과적으로 이용할 것인가라는 문제에서 한 발 더 나아가 얼마만큼의 빛을 받아들일 것인가를 고민하게 하는 촬영이다. 바로 이 문제는 노출시간으로 연결되며 조리개 값을 실정하게 한다. 더불어 작가의 낭만적인 미적 감각을 함께 표현할 수 있는 촬영방법이다.

Simulated acid rain(SAR) treatment caused a lethal effect on the newly germinated seedlings of Capsicum annum cv. Komyung even though the germination rate of the seeds was stimulated by the treatment of SAR. Young germinated seedlings were much more sensitive to SAR than the already-grown seedlings. The typical symptom caused by SAR was white spot or lesion on the leaf and appeared readily and severely at the low pH of SAR. Generally, Phytophthora rot was severer in SAR treatments than in control. However, the disease was less severe in lower pH of the SAR treatment than in higher pH. Pathogen inoculation following the SAR treatment increased the disease. The severest Phytophthora rot was observed in the SAR treatment of pH 4.0 or 4.5 regardless of the inoculation time.

In this paper, for manufacturing a custom-made shoes, shape of foot acquired three-dimensional measurement device which makes shoe-last data for needing a custom-made shoes is founded on artificial intelligence technique and it shows method restoring to the original shape in optimized state. the developed system for this study is based on PC which uses existing three dimensional measurement method. And it gains shoe-last and data of foot shape going through 8 CCD(Charge Coupled Device) Which equipped top and bottom, right and left sides and 4 lasers which also equipped both sides and upper and lower sides. The acquired data are processed image processing algorithm using artificial intelligence technique. And result of data management is better quality of removing noise than other system not using artificial intelligence technique and it can simplify post-processing. So, this paper is constituted hardware and software system and it used neural network for determining threshold value, when input image on pre-processing step is being stage of image binarization and present that results.

Artificial acid rain (pH 3.0, 4.0 and 5.0) was treated on the seeded pots of 4 species to examine its effects on germination, leaf injury and seedling growth. Artificial acid rain was prepared by diluting sulfuric acid with ground water and ground water (pH 6.5) was used as control. Artificial acid rain was sprayed to seeded pots three times per week. About 5mm of artificial acid rain was treated each time from early April to early October, 1991. Germination, seedling establishment, leaf injury, soil acidity and seedling growth were measured and compared among the treatments. The results were summarized as follows; 1. Germination and seedling establishment rate of Pinus thunbergiana was highest on the pH 4.0 pot whereas that of Picea abies was highest on the pH 3.0 pot. Those of Pinus densiflora and Abies holophylla were not significantly differed among the treatments. 2. The differences in seedling height of all species were not significantly differed among the treatments. 3. Seedling dry weight of Pinus densiflora differed significantly among the treatments. but that of Pinus thunbergiana did not differ. 4. With decrease of pH value of artificial acid rain. the number of injured needle and injured individual tended to be increased. 5. The differences of soil acidity were significant among the treatments for all species.

The space center will be constructed by 2005 for launch of KSLV-I at Woinara-Do, Haban Village, Yenae-Ri, Bongrae-Myon, Kohung-Goon, Junlanam Province on the southern coast of the Korean peninsular. This will make Korea be the 13th advanced country in space development having launching site in the world. This paper presents licensing and safety requirements to protect the public from the risks associated with activities at a launch site.

In the 21st century, as we enter the Fourth Industrial Revolution, research in various fields utilizing big data is being conducted, and innovative and useful technologies are constantly emerging in the world. Among several technologies recently in the big data era, among various fields utilizing some algorithms of artificial intelligence, it shines in the field of finance and is used for pin tech, financial fraud detection and risk management, etc., and recently Even in the booming stock market, it is used for investment prediction and investment factor analysis using artificial intelligence algorithm models. In this paper, we plan to investigate various research cases and investigate trends in how they are used in the stock market through artificial intelligence that utilizes big data.
