The scope of this study was limited to the first spelling question out of 30 Vietnamese questions of each SAT from 2014 to 2023. To analyze the difficulty of the spelling questions, we analyzed the format of the questions focusing on the questions sentence and examined how many times the vocabulary in the questions was exposed, starting from which page of the EBS CSAT Special Lecture, which is the main exam book in reality. In addition, as another criterion for measuring difficulty, we used the Vietnamese vocabulary classification presented in the standard curriculum developed as part of the Critical foreign Languages Education Promotion to see what level the vocabulary on the question corresponds to. To summarize the characteristics of the four periods divided based on the questions sentence, the difficulty level of the spelling questions was inconsistent over the past 10 years and became difficult in the second period, but through the third and fourth periods, the level of completion increased and the difficulty level found its appropriate level.

In this study, the PBL class was applied to a Vietnamese video class. 13 learners were divided into 3 groups, and it was examined whether all learners grew toward their learning goals, and if so, through what process they grew. When group 1 announces a task, groups 2 and 3 perform peer evaluation and submit a peer evaluation sheet. For this, group 1 categorized the contents of peer evaluation into reflecting, partially reflecting, revised, and not reflecting to prepare the presentation evaluation sheet. Further, they were required to write a reason why “not reflecting.” A reflection log was also submitted. As a result of the above, the assignments were immediately revised, supplemented, and developed every week through peer and instructor evaluation. Through this process, the instructor learned in detail what kind of reflection the presenter and team members were doing each week. In particular, learners achieved ‘up-leveling’ with the activeness of immediately accepting each other’s strengths while conducting peer evaluations on each other’s presentations. This shows that the weekly assignments are improved, while the competencies of both the presentation team and peers are developed at the same time.

For the efficient teaching and learning of Vietnamese, the researcher paid attention to Project Based Learning and tried to apply it to the class. The researcher analyzed prior studies of PBL classes, including English and other foreign languages, and applied the theory of PBL to Vietnamese language education subjects, designed PBL classes, and utilized them in classes. In addition, the process in which the learners perform tasks (student presentation, peer-faculty evaluation, evaluation opinion reflection process), the results, and the questionnaire survey on learners were analyzed. As a result, it was found that PBL methods could also be applied in Vietnamese classes. The learners reorganized the learning contents into his or her own knowledge in the relationship between the learner’s own thoughts, experiences, knowledge, and understanding by referring to the instructor’s teaching plan and lecture. In addition, it was possible to achieve more useful and viable knowledge by listening to other people’s opinions and thoughts about their own knowledge, understanding, and interpretation, and through correction and supplementation processes. Also noteworthy is that through the PBL class, the level of knowledge of each student increased rapidly.

This study is the process of finding answers to the following questions. Cultural content is needed to study Vietnamese language? Do Vietnamese language learners feel the need for classes using cultural content? Do Vietnamese teachers use cultural contents in class? In order to find out the answer, I conducted a questionnaire survey on Vietnamese students in Chungnam Foreign Language High School, interviewed teachers and analyzed the case examples. As a result of the questionnaires and interviews, it was found that the necessity of cultural contents development in Vietnamese language education is a requirement for both teachers and learners. Based on these results, we developed a case study on cultural education contents for Vietnamese language education. However, the model of teaching Vietnamese language utilizing cultural contents needs to be developed through more diverse academic analysis. Its effectiveness should also be investigated in depth. We will propose this as a future research project.

The purpose of this study is to develop a teaching and learning method that enables students to learn self-directed knowledge by inducing them to participate actively in class by breaking away from their passive role. The design and basic operating rule of student/faculty collaborative course are as follows. Firstly, students participate in designing and operating a course and professors will act as a coach instead of an assessor. Secondly, valuation standard will not be applied uniformly, but by individualized levels for each student. Thirdly, what matters is students’ growth change by semester in the long term of four-year. Their growth and changing process will be noticed by recording their presentations and utilizing it. The significance of student/faculty collaborative course is that almost all the students were interested and actively participated in the class. Students should be able to apply positiveness and confidence achieved through the course to daily life naturally. If this type of course is processed systematically in four year’s time, students will be able to develop the ability to realize problem and resolve actively. This will be a significant educational alternative for the students who remain at the middle to lower rank in the cramming educational system.

In this paper, we developed the care system for older people living alone using the RFID technologies and the living informations. The care system store living informations, extracted through a unconstrained detection method by the RFID tags and readers, into a monitering server. The unconstrained detection method improved a weakness of existing systems that detected a living informations through an infrared sensor, ultrasonic sensor, camera, consumed quantity of the tap water or gas. The result of this study will playa very important role, as a part of a composite older-welfare services. Also, in the future, accumulated living informations will be allowed for a health data of older peoples.

The purpose of this study was to identify the differences of the static and the dynamic balance reactions in the flexion syndrome (FS) and the extension syndrome (ES) group of the patients with chronic lowback pain (LBP) and healthy subjects. Twenty subjects were included in each group. By using EquiTest 5.02, the static balance was measured by the equilibrium score and the strategy score of sensory organization test (SOT), while the dynamic balance was measured by the latency of motor control test (MCT) and the sway energy of adaptation test (ADT). Oswestry Disability Index (OSI) was used to measure level of the disability in patients with chronic LBP. The equilibrium scores, the strategies of SOT, and thelatencies of MCT of three groups were compared with one way ANOVA, while the sway energy of ADT was compared with repeated measures one way ANOVA. The results of this study showed that the equilibrium scores and the strategy scores of SOT were significantly lower in patients with chronic LBP than in healthy subjects. The equilibrium scores and the strategy scores of SOT were significantly differences between the FS and ES groups in condition 5 (support surface was sway-referenced and visual information waseliminated by eye closure), and 6 (support surface was sway-referenced and visual information was altered by sway-referencing). The FS group showed delayed average reaction time at large posterior translation, however, the ES group showed delayed average reaction time at large anterior translation, Even though the sway energy of the patients with chronic LBP were greater than that of healthy subjects during the toe down (plantar flexion rotation), the values between the FS and ES groups didn't show any significant difference. The disability level showed highly correlation with the equilibrium score of the condition 5. As the results, the FS and ES groups divided by the their symptoms and signs in patients with chronic LBP showed different balance reaction. Therefore, more accurate evaluation and balance treatments are needed to focus on their symptoms and signs in patients with chronic LBP.

The purpose of this study is to evaluate the cognitive perceptual performance skills in relation to activities of daily living(ADL) by using Lowenstein Occupational Therapy Cognitive Assessment(L0TCA) to measure the cognitive perceptual performance and FIM to measure the ADL. The subjects in this study were 24 stroke patients who were admitted for intensive treatment at Department of Rehabilitation in Samsung Medical Center from December. 1997 to June. 1998. SAS was used to analyze data. Using simple regression analysis was used to measure influence of LOTCA on FIM at discharge and to measure influence of patient's concentration on both FIM and LOTCA. Stepwise multiple regression analysis was used to confirm the relationship of FIM to each subtest of LOTCA. The results of this study are as follow : 1. Statistically. LOTCA score at admission showed correlationship with FIM score at discharge. (R2 = 0.50. p<0.0001) 2. Visuomotor organization showed the most significant correlation between LOTCA on FIM at discharge. Motor FIM with perception and visuomotor organization, and cognitive FIM with perception showed significance. 3. The relationship between each subtest of FIM and each subtest of LOTCA. self-care was significantly correlated with visuomotor organization and perception. sphincter control was significantly correlated with orientation and perception, mobility and locomotion was significantly correlated with orientation and visuomotor organization, communication was significantly correlated with perception, social cognition was significantly correlated with perception and thinking operation. LOTCA is significantly correlated to FIM at discharge. Therefore, LOTCA can predict the ADL performance skills. Also, orientation and perception are the most predictable area of LOTCA throughout the entire subtests.

The purpose of this paper is to evaluate the fact that rehabilitation therapy helps stroke patients in the area of activities of daily living(ADL). The ADL evaluation tool used in this study is the modified Barthel Index. The subjects were 71 stroke patients who admitted rehabilitation department of Samsung Medical Center from January to September 1997. All subjects received rehabilitation therapy. The sbuject's ADL were evaluated on admission and again at the time of discharge. The results follows : 1. Using the modified Barthel Index, revealed on admission 38.26 points at discharge 68.73 points. 2. Severe disability(Barthe1 score 60 or less) were reduced from 84.5% on admission to 29.6% at discharge. Very severe disability(Barthe1 score 40 or less) were also reduced from 66.2% on admission to 12.7% at discharge. 3. The degree of change in each area of the modified Barthel Index were measured. There was an overall positive change during the admission period. The greatest change occurred in the category of dressing and transferring. The least change in donning & doffing a brace and wheelchair mobility. The modified Barthel Index used to assess the change in ADL function of stroke patients woulds seem to be very useful method. And there should be a focus on the recovery of ADL function in stroke patients receiving rehabilitation therapy.
