  • Objective : The surgical approach for recurrent pituitary adenoma after trans-sphenoidal approach (TSA) is challenging. We report the outcomes of the endoscopic TSA for recurrent pituitary adenoma after microscopic TSA. Methods : From February 2010 to February 2013, endoscopic TSA was performed for removal of 30 recurrent pituitary adenomas after microscopic TSA. Twenty-seven (90%) patients had a clinically non-functioning pituitary adenoma. Twenty-four (80%) patients suffered from a visual disturbance related to tumor growth. The clinical features and surgical outcomes were retrospectively analyzed for the ophthalmological, endocrinological, and oncological aspects. Results : The mean tumor volume was 11.7 $cm^3$, and gross total resection was achieved in 50% of patients. The volumetric analysis based on the postoperative MR showed that the mean extent of resection rates were 90%. Vision was improved in 19 (79%) of 24 patients with visual symptoms, and endocrinological cure was achieved in all of three functioning pituitary adenomas; however, the post-operative follow-up endocrinological examination revealed a new endocrinological deficit in one patient. Two patients required antibiotics management for post-operative meningitis. Conclusion : The endoscopic TSA can be an effective treatment option for recurrent pituitary adenoma after microscopic TSA with acceptable outcome.

  • The purpose of this study was to demonstrate the feasibility of VIA screening with cryotherapy and to record normative values for indicators anticipated in similar low resource settings. Women aged 30-49 years were targeted, resulting in 1961 women screened and treated at two primary health care (PHC) centres near Suva, Fiji. Recruitment was through provision of information, education and communication (IEC). Referrals to a gynaecology outpatient department (OPD) at a referral hospital occurred throughout the screening pathway. Participation was 32% (95%CI 31-33%), higher in iTaukei (Melanesians) women (34%, 95%CI 33-36) compared to Fijians of Indian descent (26%, 95%CI 24-28). Regression analysis, adjusted for confounders, indicated significantly lower participation in those of Indian descent, and age groups 35-39 and 45-49 years. Of those examined by VIA, 190 were positive with aceto-white lesions (9.9%), within the expected range of 8-15%, with minor geographic and ethnic variation. Positive VIA results were more common in the peri-urban area, and in those aged 35-39 years. Of women aged 30-49 years, 59 received cryotherapy (none of whom had significant complications), 91 were referred to OPD, two cervical carcinomas were identified and eight cervical intra-epithelial neoplasms (CIN) II-III were diagnosed. These results provide normative findings from a community-based VIA screening program for other similar low resource settings.

  • Objective : The authors reviewed the experience of 19 patients with orbital tumors and summarize the clinical features, surgical treatment and outcomes. Methods : The authors searched the database for all patients who underwent surgery for the treatment of orbital tumors at a single institution between 1999 and 2007. Data from clinical notes, surgical reports, and radiological findings were obtained for the analysis. Results : Orbital tumors constituted a heterogenous array of histopathology. The presenting symptoms were exophthalmos (52.6%), visual disturbance (26.3%) and pain (21.1%). The surgical approaches used were transcranial in 17 patients. Tumors located in the intraconal or perioptic space were surgically excised using a frontoorbital approach (8 cases). while pterional (3 cases). orbital (2 cases) and combined approaches (6 cases) were used for tumors in other sites. Total resection of tumors was achieved in 12 of 19 patients. In 4 patients with glioma and lymphoma only diagnostic biopsy was done. Three patients experienced visual deterioration postoperatively. Two patients had temporary diplopia, and one patient had temporary ptosis. Conclusion : Surgical treatment could be the mainstay of therapy for the majority of symptomatic orbital tumors. Many orbital tumors can be treated safely via a transcranial approach. Frontoorbital approach allows the surgeon to reach both the intraorbital and intracranial structures. Knowledge of the microanatomy of the orbit and meticulous surgical skills are necessary to overcome the pitfalls of intraorbital surgery.

  • As urban residents' standard of living has recently risen, efforts to improve urban landscapes have increased. It is very important to manage streetscapes to improve the urban landscape because they are one of the essential elements in city construction and urban landscaping. This study focuses on the indicators that manage streetscapes more accurately and realistically. To achieve this purpose, this study used dynamic simulations considering shape and layout of buildings, the primary factors in streetscapes. This study can be summarized as follows: 1. Two indicators to manage streetscape were investigated in previous studies: one to increase visual openness and the other to reduce visual overstimulation. These indicators had high correlation with scenic beauty. Therefore, increasing openness and reducing overstimulation are essential to improve streetscapes. 2. Two household tower type buildings should be arranged along roadsides to increase openness and scenic beauty. However, low tower buildings with two household are not suitable along roadsides because they create monotony and intervals are needed between buildings. 3. To increase openness, the angled arrangement of buildings is suggested $75^{\circ}{\sim}90^{\circ}(105^{\circ}{\sim}135^{\circ})$ for low buildings, $30^{\circ}{\sim}45^{\circ}(135^{\circ}{\sim}150^{\circ})$ for mid-sized buildings, and $75^{\circ}{\sim}90^{\circ}(105^{\circ}{\sim}135^{\circ})$ for high buildings. 4. To reduce overstimulation, the height and setback control regulations should be at an angle of less than $45^{\circ}$. This study suggests more accurate management guidelines by organizing the indicators that could effectively manage streetscapes and by overcoming limitations of reality shown in a static simulation.

  • This thesis sets out to study the immanent mechanism of architectural space which had been classified as external space in general. The mise en $sc{\acute{e}}ne$ could consider one among various immanent tools to deal with the singularity of interior architecture. An imaginary interrelationship between cinema and architecture offers a possibility which a mise en $sc{\acute{e}}ne$ could be used with a space making equipment. The mise en $sc{\acute{e}}ne$ is a conscious equipment to lead a meta-function of simple visual-perception. The mise en $sc{\acute{e}}ne$-space has been supposed to visual-perception cases and conscious cases in interior architecture. In particular, as a result of analysis, it becomes clear that the mise en $sc{\acute{e}}ne$-space is a kind of something signifer to expose designers's an abyss of conscious and unconscious. In my opinion, this is the very way that the contemporary interior architecture is exposed to its singularity by a mechanism of mise en $sc{\acute{e}}ne$-space. In conclusion, the psychoanalysis-frame of mise en $sc{\acute{e}}ne$-space has brought out any possibility of an interpretation about architectural immanent themes like a subject, meaning creation, and construction logic, and it has also been useful to reveal the architectural singularity.

  • This study is a model of research for the developing 3D character contents about facial expression as a sort of non-linguistic signs, focusing on an expression of emotion factors of a person. It contributes a framework for symbolic analysis about Human's emotions along with a general review of expression. The human face is the most complex and versatile of all species. For humans, the face is a ich and versatile instrument serving many different functions. It serves as a window to display one's own motivational state. This makes one's behavior more predictable and understandable to others and improves communication. The face can be used to supplement verbal communication. A prompt facial display can reveal the speaker's attitude about the information being conveyed. Alternatively, the face can be used to complement verbal communication, such as lifting of eyebrows to lend additional emphasis to stressed word. The facial expression plays a important role under the digital visual context. This study will present a frame of facial expression categories for effective manufacture of cartoon and animation that appeal to the visual emotion of the human.

  • Vocalizations of the common dolphin Delphinus Delphis, were recorded from a single hydrophone while coastal visual survey was performed in the East Sea in March 2017. Like most Delphinidae, common dolphins produce whistles, echolocation clicks, and burst-pulsed calls, with repertoires that differ between species and geographically separated populations. This study focuses on using frequency analysis to classify sounds into three categories and to compare them with those of other common dolphin populations. The fundamental frequencies of the whistles were high in the 6 to 14 kHz range, while echolocation clicks were in the 40 to 90 kHz frequency band. These results are similar to high-energy distributions in the same frequency band in other regions. Based on this study of the acoustic characteristics of dolphins off the east coast of Korea, cetacean vocalizations can be classified using a database of cetacean sounds in Korea. In addition, this technique could improve data quality for visual whale surveys and could be applied to various other research subjects.

  • In cinema, a montage can be defined as temporalization. In reverse, it is evident that this method results in the spatialization of time. In movies, you are free to go to the past or future, see separated times together, and separate the same time into different ones. Therefore, in one aspect, time is turned into space, and on the other hand, space is turned into time. In conclusion, space in cinema inevitably expresses time. The movie the creative arrangement of time and space played a big role in making a movie that simply overlaps a story from high school to the present attract over seven million audiences. Director Kang Hyung-cheol used his unique film production language to transform boring into cheerfulness and stale to delight, and he helped the audience heal their wounds from their youth. He said, "The most important aspect of movie production is creating visual stories, and the background of such visual story is time and space." This paper aims at analyzing the creative time and space production of the director in the film .

  • Purpose: In this study, the effects of stability exercise, extracorporeal shock wave therapy, and taping on pain and function in patients with myofascial pain syndrome of upper trapezius were compared. Methods: The subjects were divided into the stability exercise, ESWT and the taping treatment group and the clinical outcomes were evaluated by visual analog scale (VAS), pressure pain threshold (PPT) and a constant-murley scale (CMS) at pre-treatment and post-treatment. Paired t-test and ANOVA was used for statistical analysis. Results: All groups were statistical significance in the change in visual analog scale (p<0.05). The difference between the ESWT group and taping group was statistical significance in the change in pressure pain threshold (p<0.05) except for the taping group. Using the constant-murley scale, the stability exercise group showed a significant decrease in pain, and a significant increase in ROM, ADL, strength, total score of shoulder (p<0.05); however, the ESWT group showed no difference on ADL. In addition, there was no difference in strength for the taping group. The comparison of the effect between the stability exercise group, ESWT group and taping group in CMS showed a statistical significant difference in pain, ADL and ROM (p<0.05). Conclusion: These results indicate that stability exercise, ESWT and taping could be considered an effective and efficient treatment modality for myofascial pain syndrome of upper trapezius.

  • This study has analyzed the scanning path algorithm shown at the process of exploring spatial information through an observation experiment with the object of lobby in subway station. In the estimation of observation time by section, the frequency of scanning type was found to increase as the observation time got longer, which makes it possible that the longer the observation lasts the more the observation interruptions occur. In addition, the observation slipped out of the range of imaging when any fatigue was caused from the observation or the more active exploration took place. Furthermore, when the trend line was employed for the examination of the changes to the scanning type by time section, "concentration" "diagonal or vertical" showed a sharp and a gentle increases along with the increase of time section respectively, while "circulation. combination, horizontal" showed a reduction. The observation data of the subjects observing a space include various visual information. The analysis of the scanning type found at "attention concentration" enabled to draw this significant conclusion. The features of increase and decrease of scanning types can be a fundamental data for understanding the scanning tendency by time.
