  • The purpose of this study is to examine the relationship between reading attitude, reading amount, and personality type of college students, and to prepare a plan to improve the reading rate. As a result of the study, Reading attitudes have been shown to affect reading volume, paper book reading amount, personal reading amount, and e-book reading amount. In the personality type, openness has had a positive impact on reading and reading attitudes. On the other hand, the attention was negatively affecting the reading amount and the reading attitude, except for the amount of e-book reading. The implications derived from this are as follows. First, college students need a library environment and a library environment that can read books that can read books. Second, in order to increase the reading amount of extraversion, it is necessary to conduct dynamic reading activities in the center of the activity and conduct a local reading club activity linked to community activities.

  • This study attempted to investigate users' information needs in an educational research library, which delivers web-based digital reference services to library users, by analyzing reference questions asked by remote users. A total of 242 questions from two electronic bulletin boards was examined in terms of 6 types of questions asked and 23 subareas of education. The study found that 56.1% of reference questions on the library bulletin board were pure reference questions in curriculum, textbooks and teaching & instruction. Suggestions for effective use of digital reference services were made: easy access to menu services, use of web forms, development of digital reference systems providing search functions and response functions.

  • Purpose : This study conducted a systematic review and meta-analysis to evaluate the clinical effectiveness of laser acupuncture for each condition using information from laser acupuncture trials registered on clinicaltrials.gov from January 2013 to June 2023. Methods : We quantitatively and qualitatively analysed the results of 16 clinical trials of laser acupuncture whose research results were confirmed. A risk of bias assessment was also carried out to assess the quality of each clinical trial. Results : A meta-analysis including three clinical trials was conducted to evaluate the comparative effectiveness of laser acupuncture and sham laser acupuncture in reducing pain and found that the laser acupuncture group had a statistically significant reduction in pain compared with the sham laser acupuncture group. In addition, 11 of the 13 trials not included in the meta-analysis showed a positive effect of laser acupuncture. Conclusion : Although laser acupuncture has a long history of clinical use and a lot of research, there is still some scepticism due to the lack of a clear mechanism of action and inconsistent reports of clinical effectiveness. In addition, there is a significant lack of systematic reviews of clinical evidence for major disease specific, and ongoing research is needed to establish an objective evidence base for the clinical effectiveness of laser acupuncture.

  • Pcrosonimr westermani is a lung fluke of humans that Is usually found in the lunes but may be fecund elsewhere in many unusual locations. A case of pelvic paragonimiasis was found incidentally by surgical intervention of inamatov disease and myoma uteri. She was a 51-year-old Korean woman complaining of lower abdominal pain and intermittent vaginal spotting. Numerous Porosonimus ova were observed in the reseated omentum in the pelvis after total abdominal hysterectomy. It is suggested that pelvic paragonimiasis may be one of causative agents of pelvic inflammatory disease.

  • Thymic carcinoid or neuroendocrine tumor of thymus is a very rare disease and has poor prognosis due to frequent recurrence and distant metastasis. A 43-year-old man was refered to our hospital because of Rt. chest pain and tightness. Chest X-ray revealed $7{\times}8$cm sized mass on Rt. anterior mediastinum. Surgical excision was performed and light microscopic, immunohistochemical and electron microscopic findings were confirmed as atypical thymic carcinoid tumor with thymic cyst. The patient has been followed up without recurrence or distant metastasis postoperatively for 3 months to now. We report a case of atypical thymic carcinoid with thymic cysts.

  • Thymic carcinoid tumor is a rare mediastinal tumor, which was firstly described by Rosai and Higa in 1972. A carcinoid tumor of the thymus has recently been regarded as a distinct tumor from thymoma, and is probably Kultschizky cell origin. The pathologic diagnosis of thymic carcinoid is made from findings from light microscopy, immunohistochemical studies and electron microscopy. About 50% of thymic carcinoids were seen with endocrinopathies. Recurrences and extrathoracic metastasis are characteristics of thymic carcinoids. Surgical removal of the intial and tumor recurred are considered to be the most effective treatment today. However, the role of the adjuvant radiotherapy and the chemotherapy is still uncertain. Herein we report a case of thymic carcinoid tumor, which was confirmed by operation and pathologic study.

  • Recently, processor arrays to enhance the banRecently, processor arrays to enhance the bandwidth of buses and to reduce the complexity of hardwares, using optical buses instead of electronic buses, have been proposed in manyliteratures. In this paper, we first propose a constant-time algorithm for parentheses matching problemon a linear array with slotted optical buses (LASOB).Then, given an algebraic expression of length n, we also propose a cost optimal parallel algorithmthat constructs computational tree form in the steps of constant time on LASOB with n processorsby using parentheses matching algorithm. A cost optimal parallel algorithm for this problem that runsin constant time has not yet been known on any parallel computation models.

  • With respect to the histogenesis of the neurofibroma, there are many controversies, since von Recklinghausen postulated that neurofibromas are mainly fibrous tumors arising from the connective tissue of the nerve sheaths. According to the recent studies through the electron microscope, the neoplastic perineurial cells are regarded as the main components of the tumor. So, the neurofibroma enucleated from the median nerve at the level of proximal arm without resulting neurologic sequale was examined through the light- and electron microscope. Ultrastructurally, this tumor is composed of the perineurial cells, fibroblasts, and collagen fibers. The predominant perineurial cells show distinct basal lamina, and contain abundant microfilaments.

  • The iterative wave-function reconstruction (IWFR) method developed by Allen et al. (2004) was reviewed with concern for its applicability. The high resolution transmission electron microscopy (HRTEM) studies of the materials such as GaAs, $YBa_2Cu_3O_7$ and $Al_2CuMg$ reported in the literature were utilized in this review. In this process the basis of validity, the limiting conditions and the information limit of this method were discussed. It was particularly noted that the phase contrast image of the exit plane wave evaluated from this method reveals not only $C_s$-corrected atomic resolution within information limit, but also strong tendency of contrast proportional to the magnitude of the atomic number of compositional atoms in a crystal.
