This study was conducted to compare the food quality of domesticated species. Consumers surveyed for safe food intake and proper culture of food distribution. The results of the comparison study are as follows. Muscle moisture content, protein content, and fat content. K, P, and C showed relatively high values in the muscle of the sea bream. Fe showed low contents. As a result of measuring heavy metal component, Cd was not detected in sea bream and mullet, but $0.01{\pm}0.00mg/kg$ was detected in red mine. Other heavy metals were below the reference value or were not detected. Electrophoresis results showed that the band appeared at in red minefish. In the case of sea bream and swordfish, no distinctive features of the band were shown. In the case of sea bream, there was little difference in food science between the similar fish species and the red sea bream fish, but price was different. An environment should be created for consumers to buy the right ingredients at the price they want. It is necessary to educate consumers about food ingredients immediately.
Studies of attentional focus effects, have shown that the performer's attentional focus plays an important role in the performance and learning of motor tasks. We examined the influence of attentional focus on the performance of dual tasks (a postural task and a suprapostural task) and used electromyography (EMG) to examine whether the differences between external and internal focus were also manifest at the neuromuscular level. The subjects (n=40) stood on a balance board (postural task) and held a bar horizontally (suprapostural task). All of the subjects performed under different attentional focus conditions: external (balancer on balance board) or internal (feet) focus on the postural task, and external (balancer on bar) or internal (hand) focus on the suprapostural task. The mean displacement velocity of the bar and the percent reference voluntary contraction (%RVC) of the biceps brachii were reduced when the subjects adopted an external focus on the suprapostural task (p<.05). In addition, the mean displacement velocity of the balance board and %RVC of the tibialis anterior were reduced when the subjects adopted an external focus on the postural task (p<.05). When the subjects adopted an external focus on the suprapostural task, the mean displacement velocity of the balance board and %RVC of the tibialis anterior were also reduced (p<.05). When the subjects' attentional focus was on the postural task, there were no differences in the mean displacement and %RVC of the biceps brachii between attentional focuses. The performance of each task was enhanced when subjects focused on the respective task. The suprapostural task goals had a stronger influence on postural control than vice versa. These results reflect the propensity of the motor system to optimize control processes based on the environmental outcome, or movement effect, that the performer wants to achieve.

Cefprozil is a broad-spectrum oral beta-lactam cephalosporin consisting of cis- and trans-isomeric mixture whose ratio is approximately 90:10. Cefprozil is used to treat certain infections caused by bacteria such as bronchitis and ear, skin, and throat infections. The purpose of the present study was to evaluate the bioequivalence of two cefprozil tablets, $Cefzil^{(R)}$ tablet 250 mg (BMS Pharmaceutical Korea., Ltd.) and Procezil tablet 250 mg (Hanmi Pharm. Co., Ltd.), according to the guidelines of the Korea Food and Drug Administration (KFDA). The in vitro release of cefprozil from the two cefprozil formulations were tested using KP VIII Apparatus I method with water dissolution media. Thirty five healthy male subjects, $24.00{\pm}1.53$ years in age and $69.77{\pm}9.99$ kg in body weight, were divided into two groups and a randomized $2{\times}2$ cross-over study was employed. After four tablets containing 1000 mg as cefprozil were orally administered, blood samples were taken at predetermined time intervals and the concentrations of cefprozil in serum were determined using HPLC/UV detector. The dissolution profiles of two formulations were similar in water tested dissolution media. The pharmacokinetic parameters such as $AUC_t$, $C_{max}$ and $T_{max}$ on the basis of total-cefprozil were calculated, and computer program (K-BE Test 2002) was utilized for the statistical analysis of the parameters using logarithmically transformed $AUC_t$, $C_{max}$ and untransformed $T_{max}$. The results showed that the differences between two formulations based on the reference drug, $Cefzil^{(R)}$ tablets, were -0.81%, -3.00% and -6.83% for $AUC_t$, $C_{max}$ and $T_{max}$, respectively. There were no sequence effects between two formulations in these parameters. The 90% confidence intervals using logarithmically transformed data were within the acceptance range of log 0.8 to log 1.25 (e.g., log 0.9515~log 1.0454 and log 0.9613~log 1.0465 for $AUC_t$ and $C_{max}$, respectively). Thus, the criteria of the KFDA bioequivalence guideline were satisfied, indicating Procezil tablet was bioequivalent to $Cefzil^{(R)}$ tablet.
Bambuterol hydrochloride, dimethylcarbamic acid 5-[2-(1,1-dimethylethyl)amino-1-hydroxyethyl]-1,3-phenylene ester hydrochloride, is the prodrug of active ${\beta}_2$-adrenergic metabolite terbutaline. The purpose of the present study was to evaluate the bioequivalence of two bambuterol hydrochloride tablets, $Bambec^{(R)}$ tablet 10 mg (Yuhan Co., Ltd.) and Bambucol tablet 10 mg (Sam Chun Dang Pharm. Co., Ltd.), according to the guidelines of Korea Food and Drug Administration (KFDA). In vitro release of bambuterol from two bambuterol hydrochloride formulations was tested using KP VIII Apparatus II method with various dissolution media. Twenty eight healthy male Korean volunteers, $23.86{\pm}1.65$ years in age and $68.98{\pm}9.58$ kg in body weight, were divided into two groups and a randomized $2{\times}2$ cross-over study was employed. After two tablets containing 10 mg as bambuterol hydrochloride were orally administered, blood samples were taken at predetermined time intervals, and the concentrations of bambuterol in serum were determined using column switching HPLC with UV detector. The dissolution profiles of two formulations were similar in all tested dissolution media. The pharmacokinetic parameters such as $AUC_t$, $C_{max}$ and $T_{max}$ were calculated, and ANOVA test with K-BE Test 2002 was utilized for the statistical analysis of the parameters using logarithmically transformed $AUC_t$, $C_{max}$ and untransformed $T_{max}$. The results showed that the differences between two formulations based on the reference drug, $Bambec^{(R)}$, were -8.10%, -3.82% and 12.65% for $AUC_t$, $C_{max}$ and $T_{max}$, respectively. There were no sequence effects between two formulations in these parameters. The 90% confidence intervals using logarithmically transformed data were within the acceptance range of log 0.8 to log 1.25 (i.e., log 0.8093~log 1.0302 and log 0.8564~log 1.1280 for $AUC_t$ and $C_{max}$, respectively). Thus, the criteria of the KFDA bioequivalence guideline were satisfied, indicating Bambucol tablet 10 mg was bioequivalent to $Bambec^{(R)}$ tablet 10 mg.
An objective of this study is to evaluate the structural performance of the weak axis SRC column-RC beam joints by experiments. Although one of common joint types is the connection with standard hooks, it has been required to examine its safety and to settle problems of the joint among practical engineers. Specimen types are classified into two categories, namely the type of standard hook and the type of shape improvement. The first one is consisted of three specimens which are reference type, development length modification type, and development length supplement type. Three specimens for shape improvement were made with variations on the arrangement of longitudinal reinforcements and the development length. Test results based on cyclic loadings were discussed with load-deflection curves, maximum strengths, strength degradations beyond the maximum. It was found that the standard hook types showed premature failures and consequent strength degradations due to splitting of joint concrete. However, satisfactory performance was obtained with the shape improvement type with wing-plate welding. No premature failures and strength degradations were detected with the specimens.
The importance regarding the notion of immediate medical treatment and nursing for the victims of sexual crimes is not widely recognized yet in Korea. Throughout this research is focused on the nursing systems and the system of foreign countries in reference to sexual crime victims, and the conclusion is as follows. In Korea, there are currently no educational or medical institutes for the medical handling for the victims of sexual crimes, and the role of nurses in the medical institutes is insufficient. In addition, the basis for the standard of operation regarding the initial response, evidence collection, pursuit of systematical evidence and data is not established even in the sexual assault counseling/advocacy center. Therefore, it is necessary to foster the sexual assault nurse examiner for the sexual crime victims, and to develop adequate training programs based on the present situation in Korea. Though the cooperation among government, medical institutes, and social movement groups, it is essential to initiate effective and publicly-trusted specialized training programs for forensic nurses who will be fully charged with the treatment of sexual crime victims. By introducing the sexual assault nurse examiner system, it can be possible to develop advanced treatment for the child or adolescent victims of sex crimes.
Considering the skeletal class III malocclusion that complains of mandibular prognathism, there have been some studies of the mandibular change for comparing the changes of pre operative with post operative state. Nowadays it is common to do the orthognathic 2-jaw surgery for the correction of the maxillary deficiency, the post operative stability and the esthetics. We compare and analyze the changes of soft tissue around the nose and the lip with the changes in the direction and the amount of maxilla. Patients who were diagnosed as maxillofacial deformity and received orthognathic surgery of both jaws at Yongdong Severance hospital from 2001 through 2003 were included in this study. Their lateral cephalograms were analyzed, and the post operative change of hard tissue and soft tissue were studied. Upon analyzing the preoperative cephalograms and 6 month post operative cephalograms, there were significant in the vertical change of Labialis superius(Ls) and Stomion(Stm) in soft tissue in relation to the vertical change of skeletal landmarks (Anterior Nasal Spine, Subspinale, Prosthion, Incision Superious). In addition, there were no significance in horizontal movement of the skeletal landmarks among groups. In terms of hard tissue landmarks, group 3(maxillary posterior impaction and advancement surgery group) showed significantly greater change in the vertical movement of Anterior Nasal Spine(ANS), Subspinale(A), Prosthion(Pr), and Incision Superious(Is) compared with other groups. In terms of soft tissue change, group 3 showed more significant change in the vertical movement of Ls and Stm. This study calculated the changes of the skeletal and soft tissue landmarks in order to act as a guide in planning and performing the surgery and as a reference in predicting the postoperative change of facial appearance.
Purpose: Dr. Marquardt made the facial 'phi' mask using golden ratio. Most class III patients have bulky faces and want a smaller face. Using a facial golden mask, this study estimated and compared frontal photographs before and after operation for soft tissue measurement. The golden mask can be considered as a reference tool for facial esthetic analyses especially in lower face. Methods: Forty patients who had undergone orthognathic surgery at Samsung Medical Center from January 2006 to December 2009 were included in this study. These patients had Class III malocclusion. Lateral cephalometric radiographs, frontal clinical photos of pre-op and 8~12 month later post-op, and the facial 'phi' mask using golden ratio, were used for analysis. Reduction of the lower face area, occlusal plane changes, amounts of mandible setback and amounts of maxilla posterior impaction were estimated. Results: Lower facial reduction ratio and mandibular setback amounts were significantly different between 1-jaw and 2-jaw groups. Average postoperative changes in the area of lower face between bilateral sagittal split ramus osteotomy (BSSRO) and BSSRO combined maxilla posterior impaction were compared by using an independent simple t-test and $P$ value was 0.016. Therefore, the lower facial reduction ratio and mandibular setback amount were significantly different in maxilla posterior impaction. Conclusion: The two-jaw surgery group showed more reduction of the lower facial area than the 1-jaw surgery group. The amount of lower facial reduction was more related with the amount of mandibular setback. There was no significant relation in lower facial reduction with amount of maxilla posterior impaction, pre-op occlusal plane, post-op occlusal plane and the mandibular angle. A relationship between the change in the lower facial area and the amount of maxilla posterior impaction or the change of mandibular angle occlusal plane at pre-op could not be found because of the difference in the amount of setback between two groups.
Objective: Soft tissue changes due to orthodontic treatment has large individual variation. Therefore continuous evaluation during treatment is required. Patients with fixed orthodontic appliances often wonder if their lip positions will change after the removal of brackets, but only a few studies exist on this topic. The objective of this study was to evaluate the changes of the lips and perioral soft tissue after bracket removal. Methods: The sample used in this study was 19 males and 33 females. Cephalometric X-rays were taken at 3 stages - T1 (before debonding), T2 (just after debonding), T3 (1.5 months after debonding). Results: The lower lip was retruded immediately after debonding (T2-T1), and 1.5 months after debonding (T3-T2). The mean amounts of retrusion from the vertical reference plane (sG perpendicular line) were about 0.38 mm for the upper lip and 0.88 mm for the lower lip. Immediately after debonding, lip retrusion of females was greater than that of males. During the post-debonding period, lower lip of males was retruded more than that of females. Conclusion: Lips are retruded after bracket removal, and there is no gender difference 1.5 months after debonding.
This study aims to categorize and analyze internationally standardized sea names based on their origins. Especially noting the cases of sea names using country names and dual naming of seas, it draws some implications for complementing logics for restoring the name East Sea. Of the 110 names for 98 bodies of water listed in the book titled Limits of Oceans and Seas, the most prevalent cases are named after adjacent geographical features; followed by commemorative names after persons, directions, and characteristics of seas. These international practices of naming seas are contrary to Japan's argument for the principle of using the name of archipelago or peninsula. There are several cases of using a single name of country in naming a sea bordering more than two countries, with no serious disputes. This implies that a specific focus should be given to peculiar situation that the name East Sea contains, rather than the negative side of using single country name. In order to strengthen the logic for justifying dual naming, it is suggested, an appropriate reference should be made to the three newly adopted cases of dual names, in the respects of the history of the surrounding region and the names, people's perception, power structure of the relevant countries, and the process of the standardization of dual names. In order to endow East Sea with the meaning of the east of the Eurasian continent, westerners' perception on the Far East should be elaborated in more detail.
