This study was conducted to investigate the effect of total neutral detergent fiber (NDF) and forage-derived NDF (fNDF) on nutrient intake and milk production in Holstein dairy cows. Thirty-six Holstein dairy cows at weeks 4 to 20 of lactation were included in this study. The cows were arranged in a randomized complete block design and assigned to one of six diets: 1) 38% NDF with 18% fNDF (HN-HF); 2) 38% NDF with 15% fNDF (HN-MF); 3) 38% with 12% fNDF (HN-LF); 4) 34% NDF with 18% fNDF (LN-HF); 5) 34% NDF with 15% fNDF (LN-MF); and 6) 34% with 12% fNDF (LN-LF). The cows were fed a total mixed ration twice daily (07:00 and 18:00 h) and given ad libitum access to feed and water throughout the experiment. Data on the intake of nutrients (DM, NEl, CP, NDF, fNDF, NFC), milk yield, composition, fat-corrected milk (FCM), fat and protein corrected milk (FPCM), and energy corrected milk (ECM) were analyzed. Lower dietary concentrations of total NDF or fNDF resulted in an increase in DM, NEl, and NFC intake (p<0.01), milk yield (p<0.05) and a lower milk fat concentration (p<0.01). The LN treatment showed no significant differences in milk fat concentration compared to the HN however, further reduction in fNDF decreased milk fat content (p<0.01). The lowest level of milk fat was observed in the LN-LF diet group. Changes in the dietary concentrations of NDF or fNDF did not affect the concentrations of milk protein or SNF (solid not fat), although the yield of milk protein and SNF increased with higher milk yield (p<0.01). The level of fNDF influenced the level of FCM (p=0.07), as well as FPCM and ECM yield (p<0.05). A highly positive correlation between fNDF intake and milk fat concentration was observed in animals with low NDF compared to those offered high NDF. A strong correlation was also observed between milk yield and low NDF intake compared to high NDF intake.

This study was aimed to determine the changes in vitamin $B_5$ and $B_6$ contents compared to fresh materials after parboiling treatment of the main vegetables consumed in Korea. The specificity of accuracy and precision for vitamin $B_5$ and $B_6$ analysis method were validated using high-performance liquid chromatography (HPLC). The recovery rate of standard reference material (SRM) was excellent, and all analysis was under the control line based on the quality control chart for vitamin $B_5$ and $B_6$. The Z-score for vitamin $B_6$ in food analysis performance assessment scheme (FAPAS) proficiency test was -1.0, confirming reliability of analytical performance. The vitamin $B_5$ and $B_6$ contents in a total of 39 fresh materials and parboiled samples were analyzed. The contents of vitamin $B_5$ and $B_6$ ranged from 0.000 to 2.462 and from 0.000 to $0.127mg{\cdot}100g^{-1}$, respectively. The highest contents of vitamin $B_5$ and $B_6$ were $2.462mg{\cdot}100g^{-1}$ in fresh fatsia shoots (stem vegetables), and $0.127mg{\cdot}100g^{-1}$ in fresh spinach beet (leafy vegetables), respectively. Moreover, the vitamin $B_5$ and $B_6$ contents for parboiling treatment in most vegetables were reduced or not detected. In particular, the contents of vitamin $B_5$ in parboiled fatsia shoots and vitamin $B_6$ in parboiled yellow potato and spinach beet were decreased 20- and 4-fold compared with fresh material, respectively. These results can be used as important basic data for utilization and processing of various vegetable crops, information for dietary life, management of school meals, and national health for Koreans.

This study was investigated to compare the changes of flavors in sesame oil with roasting temperature $(110^{\circ}C{\sim}230^{\circ}C)$. In the results of analyzing the volatile flavor compounds of sesame oil with GC and GC/MS, 26 pyrazines, 11 pyridines, 9 thiazoles, 6 furans, 8 pyrroles, 5 phenols, 8 aldehydes, 8 hydrocarbons, 7 alcohols, 2 indoles, 3 ketones, 10 acids, 4 nitriles, 7 esters, and 5 others were isolated, identified, and quantified. The total amount of flavor compounds was increased with roasting temperature. Detected flavors could be devided into top(peak No. $1{\sim}91$), middle$(92{\sim}197)$ and last note$(198{\sim}224)$ by rentention time. The top notes(initial content 19.87 ppm) which contain pyrazines and provide representative roasted flavors were increased significantly with roasting temperature. Initial content of middle note(17.72 ppm) was increased to 36.71 ppm at $170^{\circ}C$, to 95.61 ppm at $220^{\circ}C$, and to 138.62 ppm at $230^{\circ}C$. Last note was almost unchanged up to $170^{\circ}C$ and increased at $190^{\circ}C$, whereas it indicated a tendency to decrease at $230^{\circ}C$. Pyrazines such as methylpyrazine, 2,5-dimethylpyrazine, 2,6-dimethylpyrazine, trimethylpyrazine, 2-ethyl-3,5-dimethylpyrazine which indicate the major components among volatile flavors were increased slightly up to $150^{\circ}C$ and revealed the higher increase than any other components above $170^{\circ}C$. This tendency was also similar to pyridines, thiazoles, and furans. Most of these compounds are assumed to be developed by thermochemical reactions of sesame components by roasting above $170^{\circ}C$. It seemed that a lot of increase in phenols above $210^{\circ}C$ resulted from the production of guaiacol. Acids were almost unchanged up to $190^{\circ}C$, increased at $210^{\circ}C$, and then decreased above $220^{\circ}C$. It seemed to be resulted from pyrolysis of free fatty acids formed from thermal oxidation of oil.

Gonadal development, gametogenesis, reproductive cycle, egg-diameter and composition, condition factor, and the first sexual maturity of the clam, Potamocorbula amurensis were investigated by histological observation. Samples were collected monthly from the tidal flat of Moonpo, Puan-gun, Chollabuk-do, west coast of Korea from November 1996 to October 1997. P. amurensis is dioecious and oviparous. The gonads were composed of a number of gametogenic follicles. The oogonia and fully ripe oocytes were $9\~12\mu$m and $50\~60\mu$m in diameter, respectively. Each of the spermatogenic follicle formed stratified layers composed of spermatogonia, spermatocytes spermatids, and spermatozoa in groups on the follicular wall. The reproductive cycle of P. amurensis could be classified into five successive stages: early active, late active, ripe, partially spawned, and recovery. Spawning occurred twice a year from May to July and from September to October, the main spawning seasons also appeared twice a year between May and June, and in October when the water temperatures reached above $18^{\circ}C$. The monthly changes in the condition factor were closely related with the reproductive cycle. Minimum size for the sexual maturation of female and male were 8.1 mm in shell length. There were two patterns for the gametogenesis: 1. After spawning, the undischarged ripe oocytes and spermatozoa in the follicles were degenerated and absorbed, but in part, the existing follicles were not contracted significantly and then they took part in new gametogenesis within one or two months (especially, in summer). 2. After spawning, each follicle was contracted, thereafter gametogenesis again occurred in newly formed follicles.

Many historical research and facet about modern art in Indonesia which formulating background of contemporary Indonesian Art. Indonesian art critic Sanento Yuliman states that Modern art has been rapidly developing in Indonesia since the Indonesian Independence in 1945. Modern Art is a part of the super culture of the Indonesian metropolitan and is closely related to the contact between the Indonesian and Western Cultures. Its birth was part of the nationalism project, when the Indonesian people consists of various ethnics were determined to become a new nation, the Indonesian nation, and they wished for a new culture, and therefore, a new art. The period 1960s, which was the beginning of the creation and development of the painters and the painters associations, was the first stage of the development of modern art in Indonesia. The second stage showed the important role of the higher education institutes for art. These institutes have developed since the 1950s and in the 1970s they were the main education institutes for painters and other artists. The artists awareness of the medium, forms or the organization of shapes were encouraged more intensely and these encouraged the exploring and experimental attitudes. Meanwhile, the information about the world's modern art, particularly Western Art; was widely and rapidly spread. The 1960s and 1970s were marked by the development of various abstractions and abstract art and the great number of explorations in various new media, like the experiment with collage, assemblage, mixed media. The works of the Neo Art Movement-group in the second half of the 1970s and in the 1980s shows environmental art and installations, influenced by the elements of popular art, from the commercial world and mass media, as well as the involvement of art in the social and environmental affairs. The issues about the environment, frequently launched by the intellectuals in the period of economic development starting in the 1970s, echoed among the artists, and they were widened in the social, art and cultural circles. The Indonesian economic development following the important change in the 1970s has caused a change in the life of the middle and upper class society, as has the change in various aspects of a big city, particularly Jakarta. The new genre emerged in 1975 which indicates contemporary art in Indonesia, when a group of young artists organized a movement, which was widely known as the Indonesian New Art Movement. This movement criticized international style, universalism and the long standing debate on an east-west-dichotomy. As far as the actual practice of the arts was concerned the movement criticized the domination of the art of painting and saw this as a sign of stagnation in Indonesian art development. Based on this criticism 'the movement' introduced ready-mades and installations (Jim Supangkat). Takes almost two decades that the New Art Movement activists were establishing Indonesian Installation art genre as contemporary paradigm and influenced the 1980's gene ration like, FX Harsono, Dadang Christanto, Arahmaiani, Tisna Sanjaya, Diyanto, Andarmanik, entering the 1990's decade as "rebellion period" ; reject towards established aesthetic mainstream i.e. painting, sculpture, graphic art which are insufficient to express "new language" and artistic needs especially to mediate social politic and cultural situation. Installation Art which contains open possibilities of creation become a vehicle for aesthetic establishment rejection and social politics stagnant expression in 1990s. Installation art accommodates two major field; first, the rejection of aesthetic establishment has a consequences an artists quest for medium; deconstruction models and cross disciplines into multi and intermedia i.e. performance, music, video etc. Second aspect is artists' social politic intention for changes, both conclude as characteristics of Indonesian Installation Art and establishing the freedom of expression in contemporary Indonesian Art until today.

Natural extract in liquid phase was adjusted to 0, 0.25, 0.5, 1, 2, and 4% concentration to check microbial changes and to measure 4, 8, $12^{\circ}C$ for refrigeration temperature. In the case of grapefruit extract, the microbial safety was maintained at all the concentrations at $4^{\circ}C$ storage, but the antimicrobial activity was maintained at $12^{\circ}C$ storage and at $8^{\circ}C$ and 21 days storage. In the case of grape seed extract, only the 4% of the culture at $8^{\circ}C$ satisfied the requirement of safety of food distribution for the last 21 days, and the safety criterion was satisfied only at 4% concentration at $12^{\circ}C$ for 18 days. Complex Scutellaria baicalensis extract showed the total number of microbial cells treated by concentration. It was confirmed that microbial flow safety was maintained at low temperature ($4^{\circ}C$). However, at $8^{\circ}C$ and $12^{\circ}C$, Exceeded the distribution limit. When polylysine was applied to brown rice cake, it showed activity in all groups except $4^{\circ}C$, but these properties were not observed at $8^{\circ}C$ and $12^{\circ}C$. At a concentration of 0.5% or more of chitosan, the growth of the microorganism is suppressed by the 21st day very stably, and a similar tendency is observed at 8 and $12^{\circ}C$, so that it may be an antimicrobial material that inhibits microorganisms. At the first day, the distribution standards for general bacterial counts were exceeded.Ethyl-pyruvate showed that microorganism safety was maintained at $4^{\circ}C$ and 1% concentration, and food safety was stable even at 2 or 4%. Glycine showed very good and stable distribution stability at $4^{\circ}C$. However, at $8^{\circ}C$ and $12^{\circ}C$, the shelf life of 14 days could not be maintained as with the addition of other antimicrobial active substances.

Recently, the aspect of regulating the legal system in North Korea has increased in quantity and shows the improvement of the evaluation of the lack of systematic consistency in the past. North Korean legislation has been negatively criticized for its lack of function and role of the legislative body and ambiguity of the legal system. In particular, the newly adopted "Legislation Law" in relation to the revision of the legislative system of North Korea contains important and clear contents to understand the legislative system and procedures of North Korea. The contents of the "Legislation Law" can be found a glimpse of the process by which the framework and procedures of the North Korean legislative process are organized more systematically. The North Korean legislation provides legal and institutional grounds for promoting internal and external policies under the Kim jong-un's regime. North Korea is focused on the nuclear issue, so there is limited information on other areas. In light of this, the purpose of this study is to examine the legislative theory and system of North Korea, and outline the theoretical basis of North Korea's emphasis on strengthening socialist judicial life, the socialist legal system, and the state theory of socialist rule of law. In addition, it can be analysed the content of actual legal reform in light of North Korea's legislative theory and system. In the study, it will examine the legislative system of North Korea and its characteristics by examining the legislative process and legislative process of North Korea. Moreover, it can be compared the contents of the Legislative Law of China with the legislative process of the DPRK and examine its characteristics. We will look at the challenges to the legislative system in North Korea and look into the future direction of the legislation. Kim jong-un's announcement of the revised legislation until recently through the publication of the 2016 Supplementary Codes is an important data for the current state of the North Korean legislation. This is because it confirms the content of the laws and regulations already known through "Democratic Chosun(a newspaper issued by North Korea Cabinet)'s statutory interpretation." However, in the case of laws and regulations related to the North Korean political system, it is still a remnant of the lagging legislation that the announcement is delayed, or it remains undisclosed or confidential. North Korean laws are developed and changed according to the changes of the times. In particular, the contents of the maintenance of foreign investment and the foreign economic law system and related internal legal system are found to change in accordance with the development direction of the socioeconomic system. If the direction of Kim jong-un's regime is to be expanded to the path of reform and opening up in the economic sector, the revision of the related laws and regulations will accelerate. Securing the transparency and objectivity of the North Korean legislative process and procedures will help to broaden the understanding of the inter-Korean legal system and to seek institutional measures for inter-Korean integration. In the future, in-depth research on the North Korean legal system will be emphasized as a basis for ultimately forming a unified Korea's legal system.

Clomiphene citrate. antiestrogen, was given to 39 infertile males whose spermatogenesis were disturbed and the efficacy of the drug was evaluated at the Department of Urology in 1980. (Table 1). Patients were divided into 3 clinical observation groups such as group I composed of 19 cases of idiopathic azoospermia, group II consisted of 15 cases of oligospermia following the vasovasostomy, and group III comprised 5 cases of testicular azoospermia. (Table 2). Clinical characteristics of these patients were as follows: Age of the patients ranged from 26 to 43 years old with mean of 34, and that of their wives ranged from 24 to 41 years old with mean of 31. Duration of marital life ranged from 1 to 21 years with mean of 5 years. Sizes of testis ranged from 6 to 25 ml with mean of 16 ml. Coital frequency ranged from 0.5 to 6 per week with mean of 2.4 per week. Levels of plasma FSH ranged from 3.15 to 23.06 lU/1 with mean of 8.15 lU/1, those of LH ranged from 2.98 to 19.89 lU/1 with mean of 8.18 lU/1 and those of testosterone ranged from 3.09 to 9.97 ng/ml with mean of 6.48 ng/ml. (Table 3). Clomiphene citrate was given in dosage of 50 mg per day (in d.) orally to 31 patients for 3 to 9 months and in dosage of 100 mg per day (b.i.d.) orally to 8 patients for 3 to 9 months. (Table 8). Semen samples were analysed monthly on each patient by routine analysis techniques. For the assessment of the efficacy of Clomiphene citrate on faulty spermatogenesis following empirical criteria were used: For semen quality: Improvement (I) represents that semen parameter increased more than 25% from basal level after the treatment, Unchange (U) expresses that semen parameter increased less than 25% of basal level or not changed after the treatment and Deterioration (D) means that semen parameter decreased from basal level after the treatment. For fertility unit (total counts ${\times}$ motility ${\times}$ morphology ${\div}10^6$): Improvement (I) represents that fertility unit increased more than 10 units after the treatment, Unchange (U) expresses that fertility unit increased less than 10 units or not changed after the treatment, and Deterioration (D) means that fertility unit decreased after the treatment. (Table 4). Results obtained from the Clomiphene therapy were as follows: Changes of spermiograme before and after the Oomiphene therapy shown in the Table 5. Sperm counts increased from 23 to 31 ${\times}10^6$/ml in group I, from 17 to 29 ${\times}10^6$/ml in group II. Other parameters of spermiogramme were not changed significantly after the treatment. Fertility units increased from 14 to 18 units after the treatment in group I, and from 16 to 18 units after the treatment in group II. Effectiveness of Clomiphene citrate on spermatogenesis was summarised in the Tables 6 and 7. After the treatment, sperm count increased in 11 patients, motility increased in 6 patients, morphology increased in 4 patients and fertility units increased in 9 patients. No sperm could be produced by Clomiphene citrate in group III of testicular azoospermia. Dosage of 50 mg of Clomiphene citrate per day for 3 to 6 months was proved to be the most effective in the present series. (Table 8). Pregnancy occurred in 2 patients after the treatment. No particular side effects were noted by the treatment. Pharmacologic compounds used for male infertility were shown in the Table 9. Reported results of Clomiphene citrate were shown in the Table 10.

This research is based on using Bartenieff Fundamentals to analyze the fundamentals of Tai Chi Chuan's movements in order to develop the methods of relaxation from Tai Chi Chuan's principle movement movements It also shows that the two techniques have commonalities in many ways. First of all, taking a philosophical approach on the body movements of Tai Chi Chuan and Bartenieff, for both methods the ultimate goal is the integration of mind and body. In other words, there is a thread of connection between the East's body and mind monism and the west's Body Awareness. Secondly, looking at it from a Breath Support standpoint as used in the Bartenieff method, the two methods both use the breathing to naturally move the body and relax the body. In Tai Chi Chuan the Breath is the basis of life and the strength of the Body. So the breathing of Tai Chi chuan is what makes body and mind communicate, harmonize and integrate. In other words, Breathing in Tai Chi is realized through mental fusion and affects the movements. This is the same as the Breath Support of Bartenieff. It is said that in every aspect the Breath Support of Bartenieff influences the movement and changes both the inner and outer form of the body. Thirdly, looking at the Core Support used in the Bartenieff method, both methods emphasize core. At the same time of moving and being conscious of one's core, the usage of muscles can be deeper rather than superficial and this enables strong and flexible movement. In Tai Chi Chuan abdominal muscles used when one coughs are consciously engaged through abdominal breathing and so strength is collected in the core. When one exercises like that the core becomes more stable and breathing becomes more smooth. Fourthly, analyzing the Rotary Factor used in the Bartenieff Fundamentals, they both use rotary movement to reach the goal of physical relaxation. The rotation factor of Bartenieff allows movement to be easier and more free because of the characteristic of joint exercise where the center axis moved in three dimensions, this is the same in Tai Chi chuan. According to Tai Chi chuan's circle and Spiral Movements, it can achieve the relaxation through switching into a seamless flow and access space as much as possible. Finally, when looking at Developmental Patterning through Bonnie Bainbridge Cohen's Body-Mind Centering Work theory, presented from Bartenieff developmental model are similar with the developmental process of Tai Chi chuan Breath, Core-Distal Connectivity/Navel Radiation, Head-Tail Connectivity/Spinal Movement, Upper-Lower Connectivity/Homologous, Body-Half Connectivity/Homo-Lateral Connectivity, Cross-Lateral Connectivity/Contra-Lateral Connectivity. They are all similar. In other words, in Tai Chi Chuan energy is gathered in the core through breathing, upper and lower body are connected through the spine, not only homo-laterally but also cross-laterally. Through this study the expression of the dance movements can be more natural. Additionally based on the Body Awareness balance usage of the central axis, joints and body can develop the relax technique.

Background: Allergic rhinitis(AR) is a heterogeneous disorder that despite its high prevalence is often undiagnosed. It is characterized by one or more symptoms including sneezing, itching, nasal congestion, and rhinorrhea. And it is frequently accompanied by symptoms involving the eyes, ears, and throat, including postnasal drainage. There are many different causes of rhinitis in children and adults. Approximately 50$\%$ of all cases of rhinitis are caused by allergy. In the case of rhinitis caused by allergens, symptoms arise as a result of inflammation induced by a gamma globulin E-mediated immune response to specific allergens such as pollens, molds, animal dander, and dust mites. The immune response involves the release of inflammatory mediators and the activation and recruitment of cells to the nasal mucosa. AR is similar to 鼻？, hypersensitive rhinitis in Oriental Medicine. I think hypersensitive rhinitis is including of AR, vasomotor rhinitis and non-allergic rhinitis related with eosinophil increased and so on. Purpose: To perform a clinical analysis of hypersensitive rhinitis including allergic rhinitis and estimate the efficacy of Oriental Medical treatment. Objective: We studied 96 patients who had visited our hospital with complaints of nasal symptoms from March 2000 to February 2002; they had the signs more than 2 - nasal obstruction, watery discharge, sneezing and eye or nasal itching. Parameters Observed & Methods: We treated them with acupuncture & herb-medication. Sometime they used aroma oil or external medicine. 1) the distribution of sex & age groups 2) the clinical type based on duration & the severity of symptom 3) the breakdown of complication & pasl history of Otolaryngologic or allergic disease 4) the clinical assessment and classification of rhinitis(sneezers and runners & blockers) 5) the associated symptoms and signs 6) the classification of Byeonjeung 7) the classification of prescriptions and 8) the efficacy of treatment. Result: 1. In the clinical type of based on duration, the intermittent type was 42.7$\%$ and the persistent was 57.3$\%$. 2. We observed the severity of symptoms based on the quality of life. The mild type was 24.0$\%$ and the moderate-severe was 76.0$\%$. 3. In the clinical assessment and classification of rhinitis, the sneezers and runners type was 69.8$\%$ and the blockers was 30.2$\%$. 4. The most common family history with otolaryngologic or allergic disease were allergic rhinitis(17.7$\%$), urticaria, paranasal sinusitis and T.B.(3.1$\%$). 5. The most common past history with otolaryngologic or allergic disease were paranasal sinusitis(14.6$\%$), atopic dermatitis and asthma(8.3$\%$). It was 31.3$\%$ they had a family history and 44.8$\%$, past history. 6. The most common complication was paranasal sinusitis(15.6$\%$). In decreasing order the others were otitis media with effusion(9.4$\%$), GERD and headache(6.3$\%$), asthma, bronchitis, nasal bleeding and allergic dermatitis(5.2$\%$). 7. Classification through Byeonjeung : ⅰ) 39 cases(34.9$\%$) were classified as showing Deficiency syndrome. The insuffficiency of Qi was 17.7$\%$, deficiency of Kidney-Yang, 12.5$\%$ and Lung-Cold, 10.4$\%$. ⅱ) 57 cases(59.4$\%$) were classified as showing Excess syndrome. The Fever of YangMing-meridian was 35.4$\%$, Lung-Fever, 24.0$\%$. 8. The efficacy of treatments showed: an improvement in 22cases(22.9$\%$); an improvement partly in 24 cases(25.0$\%$); no real improvement or changes in 16 cases(16.7$\%$); and couldn't check the results 18cases(18.6$\%$). Conclusion: We suggest that this study could be utilized as a standard of clinical Oriental Medical treatment when we treat hypersensitive rhinitis including allergic rhinitis.
