Korean children's clothes have unique aesthetic characteristics distinguished from other countries'. Our folk beliefs handed down from ancient times always contained fortune - seeking thoughts and particularly mothers' earnest wishes for the happiness of their children were sublimated into the symbolic beauty of their children's clothes. The present study examined children's clothes in the royal family and among the people for 50 years of the transitional period from the late Joseon Dynasty to modern times, by classifying them into ritual dress for new-born babies, festival dress and everyday dress. Male children's clothes included caps such as Bokgeon(복건), Hogeon(호건) and Gulle(굴레) topcoats such as Durumagi(두루마기), Sagyusam(사규삼) Koija(쾌자) and Jeonbok(전복) and others such as Magoja(마고자), Baeja(배자), Joggi(조끼) and Bajijeogori(바지저고리), Female children's clothes included caps and head ornaments such as Gulle, Jobawi(조바위) and Daenggi(댕기) and others such as Durumagi, Jegori and Chima(치마). What is interesting is that old clothes handed down to the present are mostly boys' and few of them are girls'. This is probably because of the strong preference for boys rather than girls that continued until the end of the 20th century. Ordinary people dressed their new - born babies with simple white clothes until Samchilil (the 21st day) or Baekil (the 100thday) but, for these occasions, the royal family prepared clothes as formal as those for the $1^{st}$ birthday among the public. Rainbow-striped garments were more popular among the public than in the royal family. As rainbow colors were known to Korean people to dispel evil power and bring in fortunes, rainbow - striped garments were essential for the $1^{st}$ birthday and festive days. However, they were seldom used in ordinarytimes, and most boys and girls wore plain jackets and plain topcoats. When children's clothes in noble families were compared with royal family's ones, either handed down to the present or found in old literature, no significant difference was observed in the basic composition of everyday dress. In particular, it was found that Andong Kim's family had dressed their children with very formal dress such as Dopo and Sagyusam. Among children's clothes, the most gorgeous one was that worn on the $1^{st}$ birthday, and those for other occasions or festive days were similar or simpler. Colors, patterns and designs used in decorating children's clothes mostly had the meanings of seeking fortunes for children such as long life, wealth and prosperity.

The purpose of this study is to analyze the phases of back pain occurring on pregnant women, and to raise the necessity of the pain management on the basis of the former analysis. The objective group is 284 pregnant women who visited department of OBGY of hospital located both in Seoul and Andong. The results are as follows; 1. 204(71.8%) pregnant women were suffering from back pain. The ratio of pain occurrance in terms of the duration of pregnancy shows that 78.3% within 3 pregnant months, 68.4% between four and six months and 72.1% over seven month. Most common ares of pain was low back area rating 60.5%. 2. The most painful postural for the suffering women was lying on the back rating 35.9% and the next painful posture was standing rating 34.4%. And the most painful movement was to maintaining continues movement(57.8%). Twisting back rates the second(17.2%). These two variables were relevant each other(p<0.05). 3. 46.7% of pregnant women were experiencing nocturnal pain. Among women experienced the pain before pregnancy, 39.9% were suffering during the pregnancy. The occurrence of nocturnal pain was related to the pain before and after the pregnancy(p<0.05). 4. 58.8% of pregnant women who experience back pain take the pain for granted as a normal proceeding of pregnancy while 3.9% recognize the symptom as an abnormal. Pain recognition in accordance with the phases does not show much difference(p<0.05). 5. It is shown that the more one delivers the number of babies, the faster back pain occurs(p<0.01). 6. 32.3% of the pain-suffering women have family member(s) having back pain. Family member(s) of the women who does not experience the pain don't have the pain either. This case reports 46.1%. Statistically, these two variables are relevant(p<0.01). 7. 43.0% of back pain experiencing women does not have any particular management plan against the pain. 20.7% is exercising as for prevention. Women who recognize the necessity of some means of therapy for their pain marked 42.9%. The majority(65.8%) of women responded exercise gymnastic work-out are most appropriate pain management. The above results show that a great number of pregnant women is experiencing back pain, however, they properly managed. This span suggests that appropriate advocacy and education for pregnant women is necessary. It is recommended that positive contribution can be made to better health of pregnant women when pain management by physical therapist is given.

Sorbus commixta, a flowering plant in the Rosaceae family, is native to Japan and Ulleung Island, Korea. This plant is also called maga-mok or mai-mok in Korea because the bud of the stem has a similar shape to the teeth of a horse. In this study, hot water extracts from different parts of S. commixta, such as leaf, stem, and immature and mature fruits, were prepared, and their antithrombosis and antioxidant activities were evaluated. The extraction yield and pH of stem extracts were 3.99% and 5.5, respectively. The stem extracts contained 89.2 mg/g of total polyphenols and 28.3 mg/g of total flavonoids. The hot water extracts prepared from the leaf, stem, immature, and mature fruit of S. commixta exhibited no hemolytic activity against human red blood cells, up to a concentration of 0.5 mg/ml. In an anticoagulation assay, the stem extracts showed strong extension in thrombin, prothrombin, and activated partial thromboplastin times, whereas the other extracts had no anticoagulation activity. In a platelet aggregation inhibitory activity assay, all the extracts tested had no inhibitory activity against human platelets. With regard to antioxidation activity, the stem extracts showed stronger radical scavenging activity and reducing power activity than the other extracts. The calculated RC₅₀s, the concentration required for 50% radical scavenging activity, for DPPH anions, ABTS cations, and nitrite of the crude stem extracts were 119.7, 53.3, and 117.5 μg/ml, respectively, whereas they were 13.7, 5.2, and 14.9 μg/ml for DPPH anions, ABTS cations, and nitrite, respectively, for vitamin C. The results suggest that the stem extracts of S. commixta have strong potential for use as a novel resource for antithrombosis agents.

The user's password must be encrypted one-way through the hash function and stored in the database. Widely used hash functions such as MD5 and SHA-1 have also been found to have vulnerabilities, and hash functions that are considered safe can also have vulnerabilities over time. Salt enhances password security by adding it before or after the password before putting it to the hash function. In the case of the existing Salt, even if it is randomly assigned to each user, once it is assigned, it is a fixed value in a specific column of the database. If the database is exposed to an attacker, it poses a great threat to password cracking. In this paper, we suggest variable-dynamic Salt that dynamically changes according to the user's password during the login process. The variable-dynamic Salt can further enhance password security during login process by making it difficult to know what the Salt is, even if the database or source code is exposed.

Cheongpunggye is located in a valley where Baekaksan, the main mountain of Seoul and Inwang Mountain corresponding to right-white tiger(石白虎) divination based on topography are crossed. The owner of Cheongpunggye is Seonwon Kim Sangyong and many people had visited there without pause because of beautiful landscape since the early times of Chosun. Seonwon Kim Sangyong had ever studied together with Yulgok Yi I and Woogye Seong Hon. He was one of the Western faction(Seo-in) which was the leading power of Injo Coup and died for his chastity during Second Manchu Invasion of Chosun. He is known as a model of fidelity which is a symbol for scholar's spirit in Chosun together with his younger brother Cheongeum Kim Sangheon. Jangdong region, the clan village of New Andong family was the birthplace of Yulgok School which was the fundamental of scholar spirit of Chosun. And Jangdong would be the source of Jin-Gyeong(Real Scenery) Culture which was bloomed by Baekak club composed of Gyeomjae Jeong Seon, Sacheon Lee Byeongyeon, and Gwanajae Cho Yeongseok. The contents of this study are as follows. First, this study explored the placeness of Seochon region through the historical background like the relation between Jangdong, the clan village of Andong Kim family and Andong Kim family, and achievements of Seonwon Kim Sangyong and circumstances of that times. Second, this study tried to know original landscape of Cheongpunggye by investigating location, topography, water system etc. based on analysis of literature, old map, and paintings describing Cheongpunggye. The study was progressed in this way. To infer the original landscape, about 50 landscape elements of Cheongpunggye shown in Punggyejibseunggi(楓溪集勝記), Cheongpunggye Cheop, Cheongpunggye(淸風溪), the work of Gyeomjae Jeong Sean were searched, and then the location and form of the elements was analyzed. Furthermore, by analyzing the meanings of the names for the landscape elements, the thoughts(Naturalism, Taoism, Confucianism, Buddhism) supporting the structure of Cheongpunggye could be inferred. It is thought that these findings can contribute to exploration of placeness of Cheongpunggye. The study on original landscape of Cheongpunggye can be used as basic data when these works are executed-revival of Cheongpunggye, restoration of small streams in upper part of Cheonggyecheon, renewal of Seochon region.

In this paper, we investigated whether resveratrol could induce the expression of cysteine-rich angiogenic inducer 61 (CYR61), which is a member of the CCN families. We showed that resveratrol up-regulated CYR61 protein expression in three different human colorectal cancer cell lines. In addition, resveratrol induced CYR61 protein expression in a dose- and time-dependent manner in a HCT116 cell line. To investigate the relationship between various biological activities of resveratrol and CYR61 expression, HCT116 cells were incubated with several NSAIDs, antioxidants, or resveratrol. Interestingly, resveratrol only induced CYR61 protein expression. The expression of CYR61 was not related to the presence of p53. A promoter assay revealed that the 786-bp promoter region (-732/+54) contains a regulatory region and that indole-3-carbinol and 6-gingerol could not induce CYR61 expression. In conclusion, our results indicate up-regulation of CYR61 is extremely resveratrol specific. The results can help to shed light on the unique biological function of resveratrol.

Podosphaera fusca (syn. Sphaerotheca fusca, S. fuliginea) is a causal agent of powdery mildew infections on Zinnia elegans, and has been documented in Korea since 1967. An outbreak involving about 1,000 plants in October 2008, in Yangpyeong, Korea, was caused by Golovinomyces cichoracearum. Further surveys of zinnia powdery mildew from 2008-2010 confirmed the widespread occurrence of Zinnia-Golovinomyces association in Korea. Chasmothecia of this fungus have not been found on Z. elegans in Korea. Analysis of internal transcribed spacer rDNA from five Korean collections confirmed the powdery mildew as G. cichoracearum. Comparison with the those from GenBank revealed 100% identity with sequences from zinnia powdery mildew, forming a monophyletic clade with 100% bootstrap support, and with those of G. cichoracearum parasitic on the hosts belonging to the tribe Heliantheae of the family Asteraceae.

This study estimated the prototype of Yangjindang at the time of its foundation by putting together the literature and discovered data and historical research on family related to Sangju Yangjindang, and looked at its architectural characteristics. These are summarized as follows: First, Yangjindang is an office building which was completed in three years [1629] after its start of construction when Keomgan Jojeong was at the age of 72 [1626] in his latter days and it was used for performing ancestral rites for Jojeong's forefathers of the head family of Pungyang Jo by family origin. Yangjindang was founded as a base of utopia for putting ancestral rites & commemoration, harmoniousness of a tribe, and educational idea into practice together with Ojakdang. Such a movement can be judged to interpret and apply the circumstances of the times realistically and flexibly where they tried to pursue the promotion of Confucianism & studies of the proprieties as well as the consciousness of practice, and to bring a tribe into harmony after the war through the retirement of Toegye School. Second, it is located at a topographically ideal spot on the edge of the Jangcheon-a tributary of Nakdong with a good physiology and landscape and its location was also the lot for a house of Jojeong's ancestor, which was burned down by war. Behind such a location and planning of Yangjindang, it is presumed, though not certain that it was modelled after Naeap village at Andong- Jojeong's parents-in-low's home. Third, as for its foundation size, it's a head house as much as about more than 100-kan, and its structure is composed of Samyo, Bonche, and Yangjindang. In addition, arrangements of buildings and its composition system and renovation procedures followed Chu-tzu Garyoe. Composition of Samyo can be restored to Yangjindang, Jugo, Woesammun, and Samyo; however, there has been no case of existence in case of Jugo building composition & arrangement takes on an aspect of a compromise between Gamyojido and Sandangjido of Garoe, which seems to be the result from flexibly interpreting and applying the rituals and studies of the proprieties of Toegye School in keeping with locational topography and realistic circumstances while making it a principle for them to observe by Toegye School. There exists a difference between Bonche and its counterpart of the upper class housing at Sangju district in that Bonche[main building] is a squre-shaped 'Ttuljip' typical of Andong setting a family ancestral ritual as a main function. Fourth, there existed a lot of hardships in raising money to cover repairs in time of doing repairs to this structure after 180 years since its establishment. In case of the repair work on Bonche, the level of renovation was limited to the replacement of old materials for rafters, doorpost, roof members and railings with new materials, together with partial alterations in case of window system. It is estimated that Yangjindang was renovated in 1808, and afterwards it was renamed Okryujeong after being re-built at another site. Through the repairs, the floor was expanded for the clan's meeting, and angle rafters and roof members were mended as well. Especially, the plane and structure of Okryujeong which was re-built at another site are expected to give clues to its restoration due to the resemblance to original appearance of Yangjindang at the time of its renovation in 1808.

Jongga means a head family by only first son's line of each generation. It is our culture's root and identity. It also includes ritual for continuing filial duty. Ritual takes the main role on jongga culture to pay respects to Jongga's ancestors and roots. Therefore, ritual costume's importance can not be neglected. We will check a Po mainly for Jongga ritual costumes' types and designs to refind Jonggas identity and its meaning. In this research, areas are divided to Gyoungsang by Youngnam sect and Jeonla by Kiho sect. Geochang, Andong in Gyoungsang province and Haenam, Namwon, Youngkwang in Jeonla province where currently first sons of Jongga reside have been researched. The method is based on Books and visits on the places. Ritual costumes' types and designs are different between Gyoungsang and Jeonla. Firstly, now in Jongga, only a Dopo and a Durumagi are worn while the manner book shows a Danryoung, a Jikryoung, a Dopo and a Simu. Also costumes are variable on areas. Secondly, a Po is characterized by its sleeve and back-line's inside skirt. In a Po, Gyoungsang has a Duri sleeve and Jeonla has a Duri sleeve which has been changed from a Dunggun sleeve. While Gyoungsang has rectangle-shaped two pieces cloths and a split in a bottom, Jeonla has both a Mu with a split back and a complete split back in back-line's inside skirt. It seems that Youngnam sect's fundamentalism and Kiho sect's flexibility about culture of old political groups would have influenced on these patterns.
