  • Purple acid phosphatase is important for phosphorus remobilization in plants, but its role in plant adaptation to low phosphorus availability is not known. The cDNA encoding O. sativa purple acid phosphatase (OsPAP1) has 1008 bp with an open reading frame of 335 amino acid residues. The amino acid sequence of OsPAP1 cDNA shows of 50-51% identity with other plant purple acid phosphatases. OsPAP1 was expressed in rice plants and in cell cultures in the absence of phosphate ($P_i$). The expression was organ-specific with the strongest expression in $P_i$-deprived roots. Functional expression of the OsPAP1 gene in the transgenic Arabidopsis line was confirmed by northern and western blot analysis. OsPAP1 overexpression lines had higher phosphatase activity than wild-type. Overexpression of OsPAP1 in Arabidopsis plants resulted in increased Pi accumulation under Pi sufficient condition. These results show that the OsPAP1 gene represents more efficient $P_i$ uptake and can be used to develop new transgenic dicotyledonous plants.

  • To prevent the damage to human health by climate change, vulnerability assessment should be conducted for establishment of adaptation strategies. In this study, vulnerability assessment was conducted to provide information about vulnerable area for making adaptation policy. vulnerability assessment for human health was divided into three categories; extreme heat, ozone, and epidemic disease. To assess vulnerability, suitable indicators were selected by three criteria; sensitivity, adaptive capacity, and exposure, spatial data of indicators were prepared and processed using GIS technique. As a result, high vulnerability to extreme heat was shown in the low land regions of southern part. And vulnerability to harmful ozone was high in the surrounding area of Dae-gu basin and metropolitan area with a number of automobiles. Vulnerability of malaria and tsutsugamushi disease have a region-specific property. They were high in the vicinity of the Dimilitarized zone and south-western plain, respectively. In general, vulnerability of human health was increased in the future time. Vulnerable area was extended from south to central regions and from plain to low mountainous regions. For assessing vulnerability with high accuracy, it is necessary to prepare more related indicators and consider weight of indicators and use climate prediction data based on the newly released scenario when assessing vulnerability.

  • Objective: The purposes of this study were to evaluate size-specific dose estimate (SSDE) of low-dose CT (LDCT) in the Korean Lung Cancer Screening (K-LUCAS) project and to determine whether CT protocols from Western countries are appropriate for lung cancer screening in Korea. Materials and Methods: For participants (n = 256, four institutions) of K-LUCAS pilot study, volume CT dose index ($CTDI_{vol}$) using a 32-cm diameter reference phantom was compared with SSDE, which was recalculated from $CTDI_{vol}$ using size-dependent conversion factor (f-size) based on the body size, as described in the American Association of Physicists in Medicine Report 204. This comparison was subsequently assessed by body mass index (BMI) levels (underweight/normal vs. overweight/obese), and automatic exposure control (AEC) adaptation (yes/no). Results: Size-specific dose estimate was higher than $CTDI_{vol}$ ($2.22{\pm}0.75mGy$ vs. $1.67{\pm}0.60mGy$, p < 0.001), since the f-size was larger than 1.0 for all participants. The ratio of SSDE to $CTDI_{vol}$ was higher in lower BMI groups; 1.26, 1.37, 1.43, and 1.53 in the obese (n = 103), overweight (n = 70), normal (n = 75), and underweight (n = 4), respectively. The ratio of SSDE to $CTDI_{vol}$ was greater in standard-sized participants than in large-sized participants independent of AEC adaptation; with AEC, SSDE/$CTDI_{vol}$ in large- vs. standard-sized participants: $1.30{\pm}0.08$ vs. $1.44{\pm}0.08$ (p < 0.001) and without AEC, $1.32{\pm}0.08$ vs. $1.42{\pm}0.06$ (p < 0.001). Conclusion: Volume CT dose index based on a reference phantom underestimates radiation exposure of LDCT in standard-sized Korean participants. The optimal radiation dose limit needs to be verified for standard-sized Korean participants.

  • This study will explore Rococo chinoiserie not only as a prominent style of the decorative arts in general, but also as an important factor that influenced $18^{th}$ century fashions in dress. Two premises support the conclusion of this study. One is that the chinoiserie is truly a hybrid, a totally new style resulting from the mixture of various traditional elements from the East and the West, with little regard for the authentic nature of the original styles. The other is that the geographical scope for defining the chinoiserie influence in the Rococo fashion can be expanded beyond its lexical meaning; the style eventually encompassed visual cues from various Eastern cultures including China, India and Turkey. Regardless of the specific origins, the oriental influences for Rococo fashion can be categorized into two types. The first type is a complete appropriation of structural elements of Eastern clothing, such as pagoda hats, pagoda sleeves, turbans decorated with plumes or fur-trimmed open robes and then combining them with Western dress. These exotic and fancy dress ensembles were worn as masquerades, theatrical costumes or portraits. One extraordinary example is the banyan, a man's dressing gown, which also had a place in everyday life, not just as special costume. Although the banyan became more tailored as time passed, the traditional shape of this Eastern garment was accepted unaltered in the beginning of the $18^{th}$ century. The second type of influence shows in the use of eastern textiles, especially silks, which were made into women's dress. It did not matter to the fashionable lady if her dress was made of the silk produced in China or a European copy of the Chinese original, as long as it satisfied her taste. It is difficult to detect the signs of exotic style from a glance in this type of chinoiserie dresses since it was more ambiguous and conservative adaptation of the oriental influence in Rococo dress styles than the first type. In this study, various oriental influences appearing in $18^{th}$ century Rococo fashions can be defined as part of the chinoiserie style based upon the suggested premises. No matter what the origin of these oriental fashions was, this hybrid of the East and West made one of great impacts on the most frivolous and splendid period of western fashion history.

A Study on 'Dangdokyeok' Epidemics in the Early 17C of the Joseon -Focusing on Heojun's 『Byeokyeoksinbang』- (17세기 초 조선에서 유행한 '당독역'에 대한 연구 -허준의 『벽역신방』을 중심으로-)

  • Various aspect of epidemics broke out continually from the middle of Joseon Dynasty due to the famine and drought caused by abnormal climate of the sixteenth century and the war. Thus the Dynasty performed sacrificial rites, isolated the patients and published plenty of medical books related epidemics in order to cure of the patients, and Heojun edited 『Byeokyeoksinbang』 as 'Dangdokyeok' broke out at Gwanbuk(關北) districts in 1613, Heojun explained the cause of Dangdokyeok as meteorology under the feudal conditions, and concluded Simhwa(心火) by fever toxin, Therefore he selected the method of puting out Simhwa by attack of fever toxin. In addition he presented emergency treatment that can maintain the airway by bleeding. To treat Dangdokyeok, Heojun presented lots of prescriptions so as Seungmagalgeuntang(升麻葛根湯), Cheongyeolhaedoksan(淸熱解毒散), Yeongyopaedok-san(連翹敗毒散), Bangpungtongsaongsan(防風通聖散), Jowiseunggitang(調胃升氣湯) and Hwangryeonhaedoktang(黃連解毒湯) etc. And he proposed Samdueum (三豆飮), Realgar(石雄黃) and so on to prevent infection from that. They presume from 120 to 150 years as the period of human adaptation to the first epidemics. Dangdokyeok put a large number of people to death at first, but it wasn't referred at the history any more after Byeokyeoksinbang. So we can say that the treatment of Heojun may be effective. Common cold and dyspeptic cold broke out in our country differently from 'Shanghan(傷寒)' in the China, so we had settled 'pestilence infectious epidemic disease(瘟疫)' while 'epidemic febrile disease(溫病)' of the China. Dangdokyeok of Heojun is similar to 'Scalet fever' belonging to 'virulent heat pathogen(溫毒)', 'newly epidemic febrile disease(新感溫病)'. As a cure of Dangdokyeok, the Korean medicine uses the treatment of removing fever state whereas the western medicine uses the antibiotics to kill the streptococcus. The symptoms of Dangdokyeok are remarkably similar to those of the Scarlatina, so this occupies a high position on the world history of medicine in aspects of the period and details of symptoms. These days we have the problems that the tolerance of antibiotics increases and disease of unknown cause is prevalent. It means the western medicine get to limits. So if we progress epidemiography based on Heojun's medicine, we may contribute to the world history of medicine.

  • Objectives : The objective of this study was to investigate the improvement effect of Sprout of Coix lacryma-jobi var. mayuen Stapf water extract (SC) on the dextran sulfate sodium (DSS)-induced ulcerative colitis mice. Methods : The antioxidant activity of SC was measured through total polyphenol and total flavonoid content in vitro. The experiment was conducted with seven-week-old male Balb/c mice. After 1 week adaptation, acute colitis was induced by oral administration of 5% DSS dissolved in drinking water, for 7 days. And normal mice received drinking water without DSS throughout the entire experimental period. For each experiment, the mice were divided into 4 groups and 24 colitis mice were arbitrarily allocated into 3 groups (n = 8/group); Normal group, Control group, SC 100 mg/kg treated group (SCL), SC 200 mg/kg treated group (SCH). Serum and colon tissues were collected after one weeks of drug administration. Results : ROS levels, ONOO- levels, AST, and ALT in serum were decreased in SC treated groups compared to the control group. Western blotting measurements of Nrf2, HO-1, SOD, catalase, GPx-1/2, IL-4, IL-10, and Bcl2 showed that the SC treated groups was increased compared to the Control group. Also, western blot measurements of NF-κBp65, p-IκBα, COX-2, iNOS, TNF-α, IL-1β, Bax, and Caspase-3 showed that the SC treated groups was reduced compared to the Control group. Conclusion : Taken together, these results suggest that SC treatment can attenuate the DSS-induced colitis though inhibiting NF-κB pathway and enhancing Nrf2 pathway. Therefore, SC was the potential to be used as a natural therapeutic drug.

  • After accepting the modernized western culture, we, the Koreans, had traditionally patriarchal valuation on the family life, which has been changed into modernize on in these days. Under these circumstances, we examined into family consciousness of workmen, office workers and student of universities in Pusan with questioning papers by inquiring their general views of family, marriage, family planning , and inheritance. The results obtained can be summarized as follows. 1. General views of family 1)Most of them prefer nuclear family to gross one in structure of family. In decision of family's affairs, the lower educated persons want an unilateral relationship, which means unconditional obdience to their parent's opinion. they are more concerned about the profit of the family than that of individual. on the other hand, they want 2-generations nuclear family system. 2) Concerning children's future affairs, they want compromising method. 2. Views of Marriage 1) Date with the other sex motivated their desire to improve social adaptation and social association. 17-19 year old students regard date as a preparatory stage of marriage. They consider it most desirable date to enjoy free conversation each other. They hope their date partners are high educated. 2) The conditions of mate selection are in order character, health, vitality in living, appearance and education. The less educated placed an emphasis on vitality in living. 3) They are not much interested in marital harmony. If parents are against their marriage an account of bad marital harmony, they will take into consideration about it. 4) They wish to keep purity before marriage, as possible. They want engagement period of 6 months. Any agreeable reasons shall compel them to break off their appointment. 5) they consider it ideal for mate's age to be 26-30 years old, and also think it affirmative to follow their parent's agreement in marriage. It is considerable that they put off their marriage only because they have lots of work to do before marriage. 6)Marriage declaration is to be made on the wedding day. It still exists that they don't want to marry when they are inth same surname and family tree. But it is clear that they don't regard it as the reason of breaking off the betrothal. 3. Family Planning 1) They are willing to agree to the campaign "just two is enough". They want a son and a daughter. Even though they have two daughters, they won's bear child to get son. 2) the lower educated persons are ignorant of the method of birth control. 4. Inheritance 1)Most of them say householder inheritance is to be kept up continuously. It is reasonable that anyone who can afford to perform religious service should bear it responsibility. 2)They don't want the difference in inheritance as the conscious to the conscious of the equality of the sexes spread widely into our society, but it is worthy of notice that some of them still don't mind unequal treatment. 3) When they have no child, the property inheritances are in order his wife and his parents. According to above mentions, we conclude like this: Their consciousness of marital harmony, marriage, family planning and inheritance shows definitely passive rationism in the transitional stage which is mixed with western individualism and traditional feudalism. On account of being lack of steady fast self-conscience, they can not make their positive reaction on anything. Finally, we should make every possible efforts to have our firm self-conscience through the re-education.

  • Objectives : Although the pharmacological effects of anti-inflammatory and antioxidant action of Atractylodes macrocephala Koidzumi water extract (AM) have been proven from many studies, reports on the antioxidant effect of AM on ulcerative colitis (UC) are scarce. Therefore, we aimed at evaluating the anti-oxidant effect of AM on the DSS-induced UC model. Methods : To induce ulcerative colitis, 8-week-old male Balb/c mice received 5% DSS in drinking water for 1 week. After 1 week of adaptation, mice were divided into four groups (n=8 each) for use as normal (Normal), DSS Control (Control), DSS + AM 100 mg/kg (AM100)-treatment, DSS + AM 200 mg/kg (AM200)-treatment. After 1 week of the experiment, the animals were sacrificed, and the extracted colon tissue was analyzed for protein through western blot. Results : As a result of confirming the macroscopic changes in colon tissues to confirm the therapeutic effects of AM, the decrease in colon length was suppressed in the AM treatment group compared to the control group. In addition, as a result of biochemical analysis, AM administration significantly reduced serum glutamic oxalacetic transaminase, glutamic pyruvate transaminase levels and tissue malondialdehyde levels. As a result of confirming the protein expression level through western blot, AM administration significantly decreased the expression of NADPH-related proteins such as NOX2, p22phox, and iNOS, but significantly increased the expression of SOD, catalase, and GPx-1/2. Conclusions : AM may improve DSS-induced UC in mice by modulating NADPH and antioxidant-related proteins. In conclusion, AM showed an antioxidant effect through the improvement of oxidative stress on UC.

  • Humanity has faced destruction(chaos) due to catastrophes (Covid-19, war, earthquake) and awaits a new restoration. For civilizations and individuals, creation or creativity is essential to psychic development. Creativity is the driving force that renews an individual when a new stance and attitude of consciousness or a new adaptation to reality is desperately needed in the depth of the human mind. This article is the result of an exploration of the nature and characteristics of creativity presented by a series of four dreams. First, the definition and form of creativity were explored in the context of religion, mythology, and history of Eastern and Western. While Western mythology refers to creation or creativity originating from God, ancient China viewed creativity as expressed through the interaction of yin and yang, the movement of Tao. In East and West, the form of creation is divided into creation from nothing, creation from matter, and creation through dissolution from the matrix, which psychologically suggests that creativity or creation originates from the unconscious, the seedbed of infinite potential and creative power. Next, with insights from the second dream, the characteristics of creativity were discussed. Creativity occurs through transcendent function and 'going beyond the frame of reference,' that is, 'transgressivity.' Third, the nature of creativity was explored as the creativity of the unconscious aims for regeneration and drives the renewal of Self archetypal images within the collective and individuals. Ultimately, the creativity of the unconscious is the goal of the whole psyche and aims for individuation to become the whole. Realizing the creativity of the unconscious is the fate of humans as the second creator.

  • The validity of the energy data of the starch-foods and seaweeds in Korean food composition tables has been suspected due to possible differences in their chemical compositions from those of western food ingredients. Energy conversion parameters being used currently in nutrition has been derived in countries where food items re quite different from ours. This study was undertaken to determine the metabolizable energy of starch-foods and seaweeds by the method selected in preexperiment20). Cooked starch foods and seaweeds were freeze-dried and fed to Sprague Dawley rat with 200∼300g body weight to measure apparent metabolizable energy (AME) values and nitrogen-corrected AME (AMEn) values for four days after three days of preliminary period for adaptation to the diets. The AME and AMEn values of the wheat noodle were 4554.6, 4584.7, the Starch Vermicelli, 3763.4, 3855.7, the Ra myon, 4916.9, 4876.0, the Buckwheat noodle, 4469.7, 4442.0kcal/kg dry matter, the Potato, 4514.6, 4520.0 and those of the Bread, 3256.9, 3582.6, 3260.5, kcal/kg dry matter, respectively. Those of Sea tangle were 1437.3, 1631.3 and of Laver, 3126.6, 3171.3kcal/kg dry matter, resectively. When the AME values of the starch-foods and seaweeds measureed in present study were compared with energy values calculated by various conversion parameters such as Atwater's Rubner's, Sochun's and FAO's, there appeared dramatic differences indicating that for many of the food items, the latter energy values by conversion factors are hardly acceptable. These data also suggest that the existing energy conversion factors are not applicable to seaweeds and a further study is needed to obtain specific factors for the conversion to biological energy from the chemical composition of seaweeds.
