The advancement of information and transportation technologies in the context of economic and cultural globalization facilitates international marriages. However, it is ironic that image and fantasies play a significant role in the actual process of these marriages. Using data from a national survey conducted in 2006 (Survey for the Conjugal Life of the International Marriage Families) this study examines the experiences of Korean men and foreign wives. The findings confirm the negative impacts on marital satisfaction of the spousal image of hypergamy (i.e., imaginings of a high-earning husband and a submissive wife) and abbreviated marriage processes (i.e., broker-mediated marriage and incorrect information about a future spouse), but the detailed patterns differ by gender and by the ethnic origin of the wife. Korean Chinese (and to a lesser extent Han Chinese) wives are more negatively affected by the marriage process and spousal imaginings than are Southeast Asians and 'other' wives. While Southeast Asian wives are more likely to have received incorrect information about their husbands, they show significantly more flexible attitudes toward the marriage and spouses. Unification Church members are excluded from the analysis because their marital lives are distinctive enough to warrant separate research. As previous qualitative findings suggested, some Korean Chinese wives seem to perceive that returnees to the home country deserve an improvement in economic status as opposed to the disappointing reality. Imagining a submissive wife hurts the marital satisfaction of husbands regardless of the ethnic origin of the wife.

Network Management become more and more important issue in the network environment in which many applications such as Mail, teleconferencing, WWW and database software are operated. It can be possible for The Bridge and flouter forwarding data to select next hop device which results in routing incorrect path from the viewpoint of network design. In this paper we address the problem of finding the detour routing path due to incorrect setting on routing devices. We propose the new algorithm for finding detour routing path based on hierarchical network structure analysis using information from SNMP MIB. To prove the correctness of the proposed algorithm we have done simulation with predefined data. Simulation results show that the algorithm finds detour path correctly

All types of tourists visit the cave. The names and explanations of cave formations give very useful information to them. Unfortunately, however, there are a lot of wrong and incorrect statements in the information. Thispaper has investigated this problem in considerations for the importance of information delivery. The problem has turned out as follows: 1) Most of the cave formation names are too abstract based on the shape instead of scientific names; 2) The names are mostly available with little scientific explanation; 3) In case of explanation, wrong, incorrect and controversial statement is found.

Blended learning is a teaching method utilizing all the advantages in 'on and off-line' learning circumstances in order to enhance the learning effect and efficiency, more than the simple use of online factors in the classroom education. In this paper, we present the realization and simulation of algorithm for the realtime evaluation of low-grade and high-grade subjects in order to implement smart e-learning system, considering a lecture intelligibility. In order to grasp the levels of student's intelligibility, we simulated a function that automatically summarizes the study contents of class given by a lecturer. Especially, in administrator mode of smart e-learning system, we suggested and simulated a system in order to help the lecturer to easily manage the student's grades, and we have provided software to tell the student's intelligibility of lecture, analyzed the rate of incorrect answers, automatic judgment of lecture intelligibility and judge the weakest subject.

Conventional stereo matching techniques are based on the assumption that the features representing an object in left and right images have fixed attribute values. But, in fact, such features may take different values due to the practical stereo image formation and the image acquisition error, and thus the conventional techniques tend to result in the in the incorrect matching of features. In this paper, we propose a stereo matching mathod with a possibilistic view which copes with the possible variability of feature values. As a result, this method decreases the number of incorrect matching features when the values of corresponding features are somewhat large. The effectiveness of the proposed method is shown via computer simulation.

Today, as the hierarchical cellular system is getting more attention than before, some recent studies introduce delay based admission control (AC) scheme which delays the admission to the macro-embedded small cell for a relatively short time to prevent unnecessary handover caused by the short-term visitors of the small cell area. In such delay based ACs, when we use improper delay parameter, the system frequently makes incorrect handover decisions such as where unnecessary handover is allowed due to too short delaying, or where necessary handover is denied due to too long delaying. In order to avoid these undesirable situations as much as possible, we develop a new delay parameter decision method based on probabilistic cell residence time approximations. By the extensive numerical and analytical evaluations, we determine the proper delay parameter which prevents the incorrect handover decision as much as possible. We expect our delay parameter decision method can be useful system administration tips in hierarchical cellular system where delay based AC is adopted.

Purpose - The purpose of this study is to achieve effective system improvement and operation methods for the improvements on the ability of firms'preparation of the financial statements Design/methodology/approach - This study conducts a survey of not only the accounting staff but also accounting specialist such as CPA or CTA. Findings - For the improvements on the ability of firms'preparation of the financial statements, comprehensive improvement in accounting education is needed as follows. First, the focus of accounting education should be converted to the consolidated financial statements, case study and analysis of accounting standards. Second, Financial Supervisory Service and Korea Accounting Institute in cooperation with accountancy firm need to create an accounting education program. Third, the focus of accounting education should be converted to consumer oriented education by providing accounting knowledge with various methods of teaching. Fourth, this study suggests the creation of the committee on Accounting Education. Research implications or Originality - As a result of the incorrect practice of firms'relying on auditors to prepare the financial statements, social concerns about the reliability of accounting information are raised because the incorrect practice decreases the auditor's independence and weaken the auditor's ability to verify accounting information. Therefore, this study analyzes the current status of auditors'preparation of the financial statements.

Background: This study aimed to evaluate ChatGPT's performance accuracy in responding to questions from the national dental hygienist examination. Moreover, through an analysis of ChatGPT's incorrect responses, this research intended to pinpoint the predominant types of errors. Methods: To evaluate ChatGPT-3.5's performance according to the type of national examination questions, the researchers classified 200 questions of the 49th National Dental Hygienist Examination into recall, interpretation, and solving type questions. The researchers strategically modified the questions to counteract potential misunderstandings from implied meanings or technical terminology in Korea. To assess ChatGPT-3.5's problem-solving capabilities in applying previously acquired knowledge, the questions were first converted to subjective type. If ChatGPT-3.5 generated an incorrect response, an original multiple-choice framework was provided again. Two hundred questions were input into ChatGPT-3.5 and the generated responses were analyzed. After using ChatGPT, the accuracy of each response was evaluated by researchers according to the types of questions, and the types of incorrect responses were categorized (logical, information, and statistical errors). Finally, hallucination was evaluated when ChatGPT provided misleading information by answering something that was not true as if it were true. Results: ChatGPT's responses to the national examination were 45.5% accurate. Accuracy by question type was 60.3% for recall and 13.0% for problem-solving type questions. The accuracy rate for the subjective solving questions was 13.0%, while the accuracy for the objective questions increased to 43.5%. The most common types of incorrect responses were logical errors 65.1% of all. Of the total 102 incorrectly answered questions, 100 were categorized as hallucinations. Conclusion: ChatGPT-3.5 was found to be limited in its ability to provide evidence-based correct responses to the Korean national dental hygiene examination. Therefore, dental hygienists in the education or clinical fields should be careful to use artificial intelligence-generated materials with a critical view.

Conventional research on image restoration has focused on restoring degraded images resulting from image formation, storage and communication, mainly in the signal processing field. Related research on recovering original image information of caption regions includes a method using BMA(block matching algorithm). The method has problem with frequent incorrect matching and propagating the errors by incorrect matching. Moreover, it is impossible to recover the frames between two scene changes when scene changes occur more than twice. In this paper, we propose a method for recovering original images using EBMA(Extended Block Matching Algorithm) and a region compensation method. To use it in original image recovery, the method extracts a priori knowledge such as information about scene changes, camera motion and caption regions. The method decides the direction of recovery using the extracted caption information(the start and end frames of a caption) and scene change information. According to the direction of recovery, the recovery is performed in units of character components using EBMA and the region compensation method. Experimental results show that EBMA results in good recovery regardless of the speed of moving object and complexity of background in video. The region compensation method recovered original images successfully, when there is no information about the original image to refer to.
