The purpose of this study was to investigate the effects of family conflict and self-control on school maladjustments of early adolescents. Subjects of this study consisted 662 middle school students drawn from 4 middle schools in Cheong-ju city. The results of this study were as follows: First, younger students' maladjustment to teachers was influenced by variables such as school year, economic levels, conflict strength between parents, conflict settlement between parents, reliability between parents and children, communication between parents and children and self-control, etc. In other words, students' maladjustment to teachers was high at the students in the 2nd year rather than in the 1st year, low economic level, high conflict strength between parents that younger students perceived, low conflict settlement between parents, low reliability between parents and children, high hostility between parents and children and low self-control. Second, younger students' maladjustment to the class was influenced by variables such as gender, school year, economic levels, conflict strength between parents, reliability between parents and children, communication between parents and children, and self-control, etc. In other words, young students' maladjustment to the class was high at the 2nd year students rather than at the 1st year students, low economic level, high conflict strength between parents, low reliability between parents and children, poor communication between parents and children, and low self-control. Third, younger students' maladjustment to rules was influenced by variables such as school year, economic level, conflict level between parents, hostility between parents and children, and self-control, etc. In other words, younger students' maladjustment to rules was high at the 1st year students rather than the 2nd year students of middle school, low economic level, high conflict strength between parents, high hospitality between parents and children and low self-control, etc. Fourth, younger students' maladjustment to friends was influenced by variables such as conflict strength between parents, conflict settlement between parents, hospitality between parents and children, and self-control, etc. In other words, younger students' maladjustment to friends was high at high conflict strength between parents, low conflict settlement between parents, high hospitality between parents and children and low self-control, etc. In the study, self-control was found to be the most important variable at younger students' maladjustment to teachers, class and rules, etc, and conflict settlement between parents was found to be the most significant variable at younger students' maladjustment to friends.

The long standing people's culture of Latin America based on social solidarity of the communities makes the political relations between the leader and the people very different from them of the european societies based on the representative democracy. At any rate, the main stream of the Populist Discourses sees the real populist political processes with the pejorative senses attributing the demagogue style of the leaders. In these sense, it is very important to re-consider the populism discourses of Ernesto Laclau who thinks that the populism is a way of interpreting the emergence of the people to establish the social demands in the context of populist real politics. According to Laclau, "the populism seeks for the radical reconfiguration of the revolt of the 'Status Quo' and new order". This work will confirm if this interpretation of Laclau can be applied to Peronist political regime. Meanwhile the first group of the orthodox line of the discourses on populism including Gino Germani shows that the populism is a political movement based on the manipulation and demagogue by the charismatic leader of the irrational mass during the period in transition after the crises of the traditional oligarchy in Latin America. And another line of the main stream of discourses on populism including Cardoso and O'Donnell says that the populism is a political phenomena in a period of transition towards the modernization and the national development by means of the industrialization through the substitution of the imports and the alliance between the classes after the 1930's. But these principal interpretations on populism disregards that in Argentina many urban poor working class people had lived under the racist, unequal painful social relations due to the underestimation and the discrimination by the upper and the middle class with many intellectuals. But Peronism had considered them as the new social subjects with human dignities. And so we have to rethink the clientelism also with another meanings. In this sense, the theories of Ernesto Laclau on populism is very helpful to illuminate the sensitive and ambiguous meanings of Peronism. Especially Peronism makes the urban working class maintain their life styles more tended to them of the traditional communities and go towards the anti-Status Quo. That is a key of success of Peronism not only that time but until these days. And so this study will show that it is the most important thing that Peronist regime had made the emergence of the 'people' in the meaning of advancing the democracy in Argentina.

Drug-induced immune hemolytic anemia (DIIHA) is a rare side effect of drugs. DIIHA may cause a systemic inflammatory response that results in acute multi-organ failure and death. Ceftizoxime belongs to the class of third generation cephalosporins, which are the most common drugs associated with DIIHA. Herein, we present a case of a 66-year-old man who developed fatal DIIHA after receiving a second dose of ceftizoxime. He was admitted to receive photodynamic therapy. He had a history of a single parenteral dose of ceftizoxime 3 months prior to admission. On the day of the procedure - shortly after the infusion of ceftizoxime - the patient's mental status was altered. The blood test results revealed hemolysis. Oliguric acute kidney injury developed, and continuous renal replacement therapy had to be applied. On the suspicion of DIIHA, the patient underwent plasmapheresis. Diagnosis was confirmed by a detection of drug-dependent antibody with immune complex formation. Although his hemolysis improved, his liver failure did not improve. He was eventually discharged to palliative care, and subsequently died.

Eight patients underwvnt reoperation after valve replacement surgery with a mechanical valve from January, 1992 to December, 2003. Among the various indications for reoperation, there were 4 patients with paravalvular leakage; 3 patients underwent resuturing of the area of leakage and one patient underwent redo valve replacement. Among the three patients with stenosis due to thrombosis of the valve, 2 patients underwent redo valve replacement and one patient underwent thrombectomy. In one patient, the valve functioned normally, but stenosis was caused by overgrowth of the patient and redo valve replacement was done 123 months later. There was no postoperative mortality or morbidity. After an average of 51 months ($2\~134$ months) of postoperative follow up, the patients were in good condition and were able to maintain a NYHA functional class of I or II. The operative method used, whether it be a redo valve replacement or valve sparing method, depends upon the type of lesion and the anatomic structure.

The requirement for QoS (Quality of Service) has become an important Issue as real-time or high bandwidth services are increasing, such as Internet Telephony, Internet broadcasting, and multimedia service etc. In order to guarantee the QoS of Internet application services, several approaches are being sought including IntServ (Integrated Service) DiffServ(Differentiated Srvices), and MPLS(Multi-Protocol Label Switching). In this paper, we describe the performance analysis of QoS guarantee mechanism using the DiffServ. To analyze how the DiffServ performance was affected by diverse input traffic models and the weight value in WFQ(Weighted Fair Queueing), we simulated and performed performance evaluation under a random, bursty, and self-similar input traffic models and for diverse input parameters. leased on the results of performance analysis, it was confirmed that significant difference exist in packet delay and loss depending on the input traffic models used. However, it was revealed that QoS guarantee is possible to the EF (expedited Forwarding) class and the service separation between RF and BE (Best Effort) classes may also be achieved. Next, we discussed the performance synthesis problem. (i. e. derived the conservation laws for a DiffServ networks, and analysed the performance variation and dynamic behavior based on the resource allocation (i.e., weight value) in WFQ.

In this study, we apply a lesson design process using an argumentation structure to preservice earth science teachers and analyzed argumentation levels displayed in the lesson plans written by preservice teachers in the process. As a result of the study, the preservice teachers designed a logically structured lesson by reflecting more argumentation components in the final lesson plan than the first one. In addition, in the case of lesson topics in which all argumentation elements were not explicitly presented in textbooks or curriculum, preservice teachers could not clearly reflect some argumentation components in the lesson plan. The conclusions and implications based on the results are as follows: First, it is necessary to use the argumentation structure as a tool to design logical science lessons, considering that argumentation levels of lesson plans written by preservice science teachers were improved by using argumentation structures in instructional design. Next, it is necessary to cultivate the preservice science teacher's ability to reconstruct the curriculum for science lesson design using the argumentation structure since argumentation levels of lesson plans written by preservice science teachers were limited to the argumentation components presented in the textbook and curriculum. Additionally, it is necessary to develop and apply a preservice teacher education program that uses the argumentation structure in the context of actual teaching activities so that preservice science teachers can not only understand argumentation but also improve their class expertise.

This study was intended to discuss the economic exclusion of the elderly, which may be experienced in a super-aged society, and to propose a method to improve the interpersonal satisfaction of the elderly through the expansion of social networks in order to overcome this. As a result of this study, first, it suggests that the method of overcoming economic exclusion and improving human satisfaction requires a high interest in women in the subject, and the elderly, low-educated, It was found that it is urgent to overcome the economic exclusion of the low-income class. Second, as a result of examining the effect of social network on human relationship satisfaction, it was found that the more women, the higher the age, the more shopping, and the smoother communication with children, the higher the human relationship satisfaction. Third, as a result of examining the effect of economic exclusion on human relationship satisfaction, it was found that the more leisure activities visited relatives and relatives, and the more paid facilities used social networks, the lower the relationship satisfaction. Therefore, it can be seen that improvement measures for leisure activities and social networks are required. Fourth, as a result of examining the mediating effect of the social network, the social exclusion in the causal relationship in which the independent variable economic exclusion affects the dependent variable, human relationship satisfaction, The relational network was found to have a complete mediating effect. In conclusion, economic exclusion and social network affect human relationship satisfaction, and it was found that human relationship satisfaction improved only when economic exclusion was overcome and social network was improved.

This study investigated the effects of dynamic visual on students' field independence-dependence on connecting errors and conceptual understanding in learning chemistry concepts with multiple representations. Seventh graders (N=123) at a co-ed middle school were assigned to a static visual (SV) group learning with text and static visual, and a dynamic visual (DV) group learning with text and dynamic visual. The students then learned 'Boyle's Law' and 'Charles's Law' for two class periods. Results revealed that the percentages of the DV group were lower than those of the SV group on connecting errors. However, the percentages of the students' connecting errors were still high regardless of their field independence-dependence. There was a little different tendency in the percentages of connecting errors between the two groups by students' field independence-dependence according to the types of connecting errors. The scores of the DV group were significantly higher than those of the SV group in a test on conceptual understanding. However, there was no significant interaction between the instruction and the students' field independence-dependence. Educational implications of these findings are discussed.

Cellobiose dehydrogenases (CDHs) are a group of enzymes belonging to the hemoflavoenzyme group, which are mostly found in fungi. They play an important role in the production of acid sugar. In this research, CDH annotated from the actinobacterium Cellulomonas palmilytica EW123 (CpCDH) was cloned and characterized. The CpCDH exhibited a domain architecture resembling class-I CDH found in Basidiomycota. The cytochrome c and flavin-containing dehydrogenase domains in CpCDH showed an extra-long evolutionary distance compared to fungal CDH. The amino acid sequence of CpCDH revealed conservative catalytic amino acids and a distinct flavin adenine dinucleotide region specific to CDH, setting it apart from closely related sequences. The physicochemical properties of CpCDH displayed optimal pH conditions similar to those of CDHs but differed in terms of optimal temperature. The CpCDH displayed excellent enzymatic activity at low temperatures (below 30℃), unlike other CDHs. Moreover, CpCDH showed the highest substrate specificity for disaccharides such as cellobiose and lactose, which contain a glucose molecule at the non-reducing end. The catalytic efficiency of CpCDH for cellobiose and lactose were 2.05 × 10⁵ and 9.06 × 10⁴ (M^-1 s^-1), respectively. The result from the Fourier-transform infrared spectroscopy (FT-IR) spectra confirmed the presence of cellobionic and lactobionic acids as the oxidative products of CpCDH. This study establishes CpCDH as a novel and attractive bacterial CDH, representing the first report of its kind in the Cellulomonas genus.
