Purpose: Korea is expected to enter an aged society in 2018 and then a super-aged society in early 2025. The country's aging is progressing faster than any other country in the world. However, the foundation of the elderly friendly industry is weak, and measures at the government level are urgently needed. Especially, housing problems of the elderly are one of the most urgent measures to be taken. Korea does not have the minimum residential area standard for the elderly, and the current general minimum residential area standard is based on the survey of the housing situation without scientific evidence. Therefore, both standards need to be revised as soon as possible based on scientific evidence. Methods: The minimum residential area standard has been calculated following Karl H. E. Kroemer's Min or Max design also being called as-single cut and dual cut theory- as the maximum population value and minimum population value theory of Ernest J. McCormick. Therefore there is a need for a formula made using a few key factors, such as corresponding dimension, practical dimension, clearance, spare dimension, integrated dimension. These elements can be defined and used as formulas to calculate minimum residential area standards. Results: Assuming the results of the spatial variability in this study showed that it is possible to raise the standard of living in a terms of sustainable minimum size for the young, old and all residents. Implications: The government should set a minimum residential area standard with scientific grounds and set up a policy improving the life of people who live in an needy residential environment.

An Asiatic lily (Lilium spp.) cultivar 'Onnuri' for cut and pot flower was developed in 2006 at Jeollabukdo Agricultural Research & Extension Services, Iksan, Korea. The cross was made in 1999 between 'Avignon', orange colored, and 'Nove Cento', yellow colored. A line was preliminarily selected as 'A99-6-48' by reason of stable flower color and shape among germinated seedlings. It had been multiplicated through in vitro culture and then bulbed on field during 2002~2003. After characteristics were investigated from 2004 to 2005, finally it was named as an 'Onnuri' in 2006. Flower of 'Onnuri' belongs to orange-red group with its center shown orange group. Plant height is 92.8 cm, flower size is medium as 13.8 cm. Stigma color is red-brown and blooming direction is upward-facing. Flowering time is mid-June.

The flower industry in Gyeongnam Province is the second largest flower producing area after Gyeonggi Province in Korea. Gyeongnam Province is also one of the provinces where flower industry was first introduced, which has started in the middle of 1960s. The share of Gyeongnam Province was 16.2% in area and 14.3% in sales in 2006. The most outstanding feature of Gyeongnam's flower industry is that it has been particularly specialized in cut-flower industry, the share of which was 77.6% of Gyeongnam Province in area. Another feature is that the industry continued to be shrunk in size due to the expansion of urban area. For Gyeongnam's floral industry to be competitive not only in domestic market but in international market, its competitiveness in quality and price is kept being promoted. In addition, the availability of land is essential to the growth of the flower industry of Gyeongnam Province.

The existing self-supervised learning-based CutPaste generated synthetic data by cutting and attaching specific patches from normal images and then performed anomaly detection. However, this method has a problem in that there is a clear difference in the boundary of the patch. NSA for solving these problems have achieved higher anomaly detection performance by generating natural synthetic data through Poisson Blending. However, NSA has the disadvantage of having many hyperparameters that need to be adjusted for each class. In this paper, synthetic data similar to normal were generated by a simple method of making the size of the synthetic patch very small. At this time, since the patches are so locally synthesized, models that learn local features can easily overfit synthetic data. Therefore, we performed anomaly detection using gMLP, which learns global features, and even with simple synthesis methods, we were able to achieve higher performance than conventional self-supervised learning techniques.

When apples are picked or selected by grader, the rate of wound occurrence on the skin by apple stalk is remarkably high if the apple was bigger than 3 size during the harvest time. Except this case, the other sizes showed very little similarity. The crop of apple per 1 minute was 2.9kg without cutting fruit stalk, whereas only 1.1kg of the apples were obtained due to cutting the fruit stalk. Thereby, the harvesting without cutting fruit stalk is highly effective in terms of productivity rather than cutting the fruit stalk. As far as the wound occurrence rate on apple skin by apple stalk of distance between grader's dish and accumulated board is concerned, the grader which has no distance showed quite low rate of wound occurrence compared with those grader with 3cm or 8cm distance. When the apple was being stored, there was no difference in firmness between the cut stalk apple and the uncut stalked apple, however there was slightly more weight loss in the cut stalk apple than uncut stalk apple.

Effects of particle size and physical effective fibre (peNDF) of rice straw in diets on chewing activities, feed intake, flow, site and extent of digestion and rumen fermentation in goats were investigated. A 4${\times}$4 Latin square design was employed using 4 mature Liuyang black goats fitted with permanent ruminal, duodenal, and terminal ileal fistulae. During each of the 4 periods, goats were offered 1 of 4 diets that were similar in nutritional content but varied in particle sizes and peNDF through alteration of the theoretical cut length of rice straw (10, 20, 40, and 80 mm, respectively). Dietary peNDF contents were determined using a sieve for particle separation above 8 mm, and were 17.4, 20.9, 22.5 and 25.4%, respectively. Results showed that increasing the particle size and peNDF significantly (p<0.05) increased the time spent on rumination and chewing activities, duodenal starch digestibility and ruminal pH, and decreased ruminal starch digestibility and $NH_{3}$-N concentration. Intake and total tract digestibility of nutrients (i.e. dry matter, organic matter, and starch) and ruminal fermentation were not affected by the dietary particle size and peNDF. Increased particle size and peNDF did not affect ruminal fibre digestibility, but had a great impact on the intestinal and total tract fibre digestibility. The study suggested that rice straw particle size or dietary peNDF was the important influential factor for chewing activity, intestinal fibre and starch digestibility, and ruminal pH, but had minimal impact on feed intake, duodenal and ileal flow, ruminal and total tract digestibility, and ruminal fermentation.

In this work, scientific and systematic analysis was conducted for finding out the methods and techniques of ancient ink stick making. Analysis the ancient ink stick on ancient documents and wooden writing as letter or painting, we concluded as followings. From the analysis of ancient wood by dendrochronology, wood was cut at 1899, which provided the information on the year of ink stick's made on writing on ancient wood. Single particle size for soot of ancient ink stick was 107 nm for ink on the roof-filling timber in Sinsunwonjeon of Changdeok Palace, compared to 38 to 86 nm on the letter on ancient 12 paper document. Aggregate particle size was 370 nm for ink on the roof-filling timber in Sinsunwonjeon of Changdeok Palace, but 206 to 318 nm for aggregate particle size on 12 paper documents. There was similar pattern between single particle size and aggregate particle size of soot, which might provide the information of raw material for ancient ink. From infra-red and Raman spectroscopic analysis of sheet of writing on paper or wood, there was severe interference from background material (paper or wood). From Raman spectroscopic analysis of ancient ink carefully separated from ancient wood, spectrum pattern was closer to ink stick made by the soot from pine burning.

Bacteriophage SC 921 of Lactobacillus plantarum, isolated from kimchi, showed high lytic effects at 0.2 M.O.I. level. The phage particle contained 4 major proteins (48, 34, 32, 29 kDa). Intact DNA of phage SC 921 is a double stranded linear molecule, and the genomic size is approximately 66.5 kilobase pairs (kbp). Restriction analysis of the genome showed that Sma I gave single site cut and Xba I gave 2 site cuts, while Cla I, Kpn I, and EcoR I formed 4, 5, and 6 cuts, respectively. Hind III digested phage DNA to many fragments. A restriction map of genomic DNA was constructed using the restriction endonuclease Kpn I, Sma I, and Xba I. Bacteriophage SC 921 was compared with B2 phage which had been reported to infect Lactobacillus plantarum ATCC 8014(KCCM l1322). Bacteriophage SC 921 differs from B2 phage at least in thr size of its genome and phage particle proteins.

This study attempted to investigate the effect of panel thickness on the horizontal density distribution (HDD) of medium density fiberboard (MDF) in a destructive way. Full size MDF panels with five different thicknesses such as 2 mm, 4.5 mm, 9 mm, 18 mm and 30 mm were cut into two different specimen sizes, i.e., $500{\times}500\;mm$ and $120{\times}120\;mm$ to measure the HDD. In general, the overall density of MDF panel diminished as the thickness increased, showing the highest density for the thinnest MDF panels. The HDD variation was significant for the samples of smaller specimen size ($120{\times}120\;mm$). MDF panel thickness significantly influenced to the HDD, which increased as the thickness decreased. In addition, the thinner panels showed much wider range in the HDD than those of thicker panels. The coefficient of variation (COV) of HDD also followed a similar trend to the panel density as the thickness increased. In summary, MDF panel thickness had a significant impact on the HDD within a panel. The sample size also showed a considerable effect to the HDD of MDF panels.

We analyzed crown development in Aucuba japonica Thunb. var. japonica resulting from the responses of phytoelements to habitat light conditions over a long period of time. Over the years, the degree of extension unit (EU) dimorphism and the degree of anisophylly were higher under shaded conditions than in brighter conditions. An overall temporally increasing pattern in the degree of EU dimorphism was found while no clear-cut trend was found in the case of anisophylly. EU length and number of leaves per EU co-varied in a spatio-temporal context. The number of terminal buds and their sizes acted as the key initiators of morphological differences of phytoelements which were further amplified following bud break. Leaf area density was displayed mostly in the apex peripheral layer of the crown and the apex layer received most of the incident light. There was a tradeoff between annual leaf production and mean leaf size. Depending on the heterogeneity of irradiance level within a crown, correlative growth inhibition caused higher EU mortality at brighter sites. Due to high mortality, shorter EUs had a mere role in the construction of structural framework of the crown except for the formation of some gaps. There was a strong convergence of EU dimorphism, anisophylly, EU extension growth and variations in leaf size towards formation of functional crown to reduce potential self-shading. Depending on the irradiance level, Aucuba japonica Thunb. var. japonica showed two different modes of crown expansion. At the brighter sites, individual crown expansion was progressive while at the darker sites, individual crown expanded in a diminishing manner and maintained a stable size. A plant's "growth diminishing phase" appeared earlier at shaded sites than brighter sites.
