  • A specimen of carangid fish, Seriola rivoliana Valenciennes belonging to the family Carangidae was collected for the first time in Pusan, Korea. It was similar to Seriola dumerili (Risso) by appearance, but differed in some morphological characters having the deeper body, the higher lobes of the second dorsal and anal fins, becoming straight line below 23-24th ray of second dorsal fin, the configuration of the first haemal spine. A new Korean name "Nat Jaetbang-eo" is proposed for this species.

  • Purpose: This study was performed in order to examine the effects of an smoking cessation counselling program for smoking cessation success. Method: Among a total of 468 persons who had ceased from smoking for 6-months and had visited the smoking cessation clinic of a public health center from January 2nd to December 31th in 2006, 61 in all who had a negative reaction in the urine nicotine check were selected for this study. Collected data were expiratory CO concentration, BMI, blood pressure, liver function, and lipid metabolism. These data were analyzed by descriptive statistics, repeated measured ANOVA and paired t-test with the SPSS/PC(Version 12.0) program. Result: There were significant changes in expiratory CO concentration, SBP, DBP, AST, ALT, and TG, but not in BMI, $\gamma$-GTP, TC, HDL-C, and LDL-C. Conclusion: This study showed that smoking cessation through a smoking cessation counselling program has partially positive effects for smoking cessation success. The results of this study show that the smoking cessation counselling program at the smoking cessation clinic of a public health center should be continued for smoking cessation success.

  • Pyriform sinus fistula is a rare anomaly arising from 3rd or 4th branchial apparatus and has been recognized as one cause of acute suppurative thyroiditis or acute deep neck infection. Pyriform sinus fistula must be considered when a clinician is encountered recurrent left lower neck abscess and a history of repeated incision and drainage. The confirmation of the diagnosis is made when the fistula tract is identified on a barium swallow study and when the internal orifice of the fistula is found at the apex of pyriform sinus on laryngoscopic examination. A complete excision of the fistula tract has been proposed as a treatment of choice. However, in some cases it is very difficult to resect the tract completely because of severe inflammation and repeated drainage procedure. We present three cases of pyriform sinus fistula which are successfully treated by laryngomicroscopic chemocauterization using synthetic fibrin and $AgNO_3$.

  • A new type of the human TSA homologous gene was cloned from a HeLa cell cDNA and characterized. The gene product consists of 161 amino acids with a molecular mass of 16,900. The TSA homologous protein, as a new 6th member of the human TSA (hTSA VI), exerted a thioldependent peroxidase activity with the use of thioredoxin system as a physiological electron donor. The values of $V_{max}/K_m$ of hTSA VI for $H_2O_2$ and t-butyl hydroperoxide (t-BOOH) were calculated as $5.53{\times}10^{-2}$ and $3.70{\times}10^{-2}$, respectively. This implies that hTSA VI is a peroxidase, which reduces $H_2O_2$ and t-BOOH. The mutation of $Cys^{47}$ to serine resulted in a complete loss of the peroxidase activity. This suggests that $Cys^{47}$ acts as a primary site of catalysis. The analysis of the tryptic digest derived from hTSA VI revealed that the $Cys^{47}$ exists as a free thiol form. Taken together, these results suggest that the TSA homologous protein is a new type of the human family, which exerts thioredoxin-linked peroxidase activity toward $H_2O_2$ and alkyl hydroperoxide.

  • A stemming algorithm for the Korean language free-text retrieval system has been designed and implemented. The algorithm contains three major parts and it operates iteratively ; firstly, stop-words are removed with a use of a stop-word list ; secondly, a basic removing procedure proceeds with a rule table 1, which contains the suffixes, the postpositional particles, and the optionally adopted symbols specifying an each stemming action ; thirdly, an extended stemming and rewriting procedures continue with a rule table 2, which are composed of th suffixes and the optionally combined symbols representing various actions depending upon the context-sensitive rules. A test was carried out to obtain an indication of how successful the algorithm was and to identify any minor changes in the algorithm for an enhanced one. As a result of it, 21.4 % compression is achieved and an error rate is 15.9%.

  • The purpose of this study was to identify the factors that related to obesity among 6th grade elementary school girls. The study subjects were 337 girls residing in Seoul. Not only variables of nutritional environment such as eating habits, health related behavioral variables, nutritional feeding methods during infancy, and genetic factors but also sexual maturity had been included as a obesity related factors. Association between obesity and related variables were analyzed by $x^2$(Chi-square) test. The obesity prevalence of the study subjects were 16% based on Röhrer Index(RI). Fifty-three percent of the study subjects experienced menarche at the time of data collection. Result of analysis showed that not only the nutritional enviromental variables such as eating habits, specific food preferences, and habit of exercise but also genetic factors did not show any statistically significant association with obesity. Above finding may imply that more variables other than the variables included in this study might have influenced on the obesity of the children. However sexual maturity in term of breast development showed significant association with obesity.

  • To develop the Korean standard differentiation of the symptoms and signs for the stroke(KSDS), the committee on Stroke Diagnosis Standardization of traditional Korean medicine(TKM) was organized dy nineteen experts in college of Korean medicine. On July 9th 2005, the second consultation meeting was held in Daejeon, Korea. Fifteen experts of the committee attended the meeting and they discussed the KSDS and came to a consensus. The 15-member committee consensus was as follows: First, board members defined the stroke on the basis of TKM. Second, they divided the symptoms and signs of stroke into five categories- fire and heat, dampness and phlegm, blood stasis, qi deficiency, yin deficiency. Third, the symptom indicator of each differentiation type for the stroke was recommended. KSDS-1 will be applied to the clinical practice and revised.

  • Research shows that formative assessment has a more powerful effect on student learning than summative assessment. This case study of an 8th grade algebra classroom focuses on how the implementation of Formative Assessment Lessons (FALs) and the participation in teacher learning communities related to FALs changed in the teacher's instructional practices, over the course of a year, to promote students' mathematical reasoning and justification. Two classroom observations are analyzed to identify how the teacher elicited and built on students' mathematical reasoning, and how the teacher prompted students to respond to and develop one another's mathematical ideas. Findings show that the teacher solicited students' reasoning more often as the academic year progressed, and students also began developing mathematical reasoning in meaningful ways, such as articulating their mathematical thinking, responding to other students' reasoning, and building on those ideas leading by the teacher. However, findings also show that teacher change in teaching practices is complicated and intertwined with various dimensions of teacher development. This study contributes to the understanding of changes in teaching practices, which has significant implications for teacher professional development and frameworks for investigating teacher learning.

  • The purpose of this study was to examine the dietary behavior of children according to their preference for fast food. The study was carried out on 470, 6th grade students (boys : 236, girls : 234) in September, 2002. The results are summarized as follows : The mean body mass index was 18.72 kg/$m^2$ for boys and 17.76 kg/$m^2$ $^2$ for girls. The subjective health disorder symptoms for the group preferring fast food was not significantly different than that of the other groups. The group preferring fast food consumed an inadequate volume of food, and they had an irregular and unbalanced diet. Their intake of green vegetables, vegetables, protein foods, and seaweed was significantly lower than that of the other groups. The food habit score for the group preferring fast food was lower than that of the other groups, and they had irregular meal times and had unbalanced diets. The group preferring fast food had a preference for sweet tastes, whilst members of the other group preferred a savory taste. The first choice for fast food by the group preferring fast food was hamburgers, the reason being that it tasted good. Results show that children who have a preference for fast food need to correct their dietary behavior. As a result, proper nutritional education and intervention is required in order to improve the consuming habits of children and their preference for fast food.
