Beginning in the Wei-Chin and Liu Ch´ao era(AD. 220-589), an awareness of natural beauty emerged as the major interest of scholars which created such a social atmosphere that served as the foundation of prosperous Chinese art. During the T´ang period, the desire to achieve natural beauty began to dominate every field of art including gardening. This study covers the T´ang period when scholars began to be conscious of aesthetics. The main objective of this study is to examine the significance of natural beauty as interpreted by Wangwei, an artist representative of the period, and of Wangchuan Villa in relation to aspects of garden theory. This study is mainly based on Wangwei´s anthology, landscape painting describing Wangchuan Villa, and historical records related to the Villa. The summary of conclusions of this study is as follows: 1) Wangwei´s concept of natural beauty is a combination of objective natural beauty and pastoral beauty, which stresses the essential beauty of nature. Moreover, he considered nature as a religious Utopia. 2)Wangchuan Villa, where Wangwei stayed until his death, was a place of seclusion representing his idea of natural beauty. There, he was able to realize the paradise of Buddhism full of zen aspirations. 3)From the perspective of garden theory, Wangchuan Villa can be classified as a suburb villa in terms of location, as a landscape garden in terms of elements, and as a villa based on a typical private land system in terms of forms. In addition, it may be considered as a garden that laid the foundation to realize a field of non-visible image and non-visible landscape, which is fundamental element of scholarly garden design.

Background: Gastrointestinal cancers are common malignancies associated with high mortality rates. Healthcare systems are always faced with high costs of treatment of gastrointestinal cancers including stomach cancer. Identification and prioritization of these costs can help determine economic burden and then improve of health planning by policy-makers. This study was performed in 2015 in Kerman City aimed at estimating the direct hospital costs for patients with gastric cancer. Materials and Methods: In this cross-sectional study, the medical records of 160 patients with stomach cancer admitted from 2011 to 2014 to Shafa Hospital were examined, the current stage of the disease and the patients' health status were identified, and the direct costs related to the type of treatment in the public and private sectors were calculated. SPSS-19 was used for statistical analysis of the data. Results: Of the patients studied, 103 (65%) were men and 57 (35%) were women. The mean age of patients was 65 years. Distribution into four stages of the disease was 5%, 20%, 30%, and 45%, respectively. Direct costs in four stages of the disease were calculated as 2191.07, 2642.93, 2877, and 2674.07 USD (63,045,879, 76,047,934, 82,783,019, and 76,943,800 IRR), respectively. The highest percentage of costs was related to surgery in Stage I and to medication in Stages II, III, and IV. According to the results of direct costs of treatment for stomach cancer in Kerman, the mean total cost of treating a patient in the public sector was estimated at 74,705,158 IRR, of which averages of 60,141,384 IRR and 14,563,774 IRR were the shares of insurance and patients, respectively. Conclusions: The high prevalence and diagnosis of disease in old age and at advanced stages of disease impose great costs on the patients and the health system. Early diagnosis through screening and selecting an appropriate treatment method might largely ameliorate the economic burden of the disease.

Purpose : Our study aimed to compare the effectiveness of low-level laser therapy (LLLT) and light-emitting diode therapy (LEDT) for chronic pain intensity reduction and body temperature increase in older adults with chronic pain. Methods : Overall, 144 of 332 participants' records were used in this retrospective chart review. The study was conducted at a private health center in Busan city and the integrative medical center of a tertiary care hospital in Daegu city, South Korea. Patients experiencing chronic pain for over 6 months were assigned to either the LLLT or LEDT group. Both groups underwent 16 sessions of phototherapy held twice a week for 8 weeks, with each session lasting 60 minutes. The primary outcomes for both groups were the mean visual analogue scale (VAS) scores and body temperatures in both groups. The secondary outcome was the correlation between changes in body temperature and pain intensity. Measurements were recorded at the baseline and at each follow-up session. Results : A decrease in pain intensity and an increase in body temperature (p<.001) were observed in both groups. There was a significant difference in the VAS scores and temperature changes between the groups (p<.001). Odditionally, there were significant differences in the patterns of change in the VAS score and body temperature between the groups as the sessions progressed (p<.01), and a strong inverse correlation between body temperature and pain intensity changes were observed (p<.01). Conclusion : The use of photobiomodulation therapy at a specific wavelength may improve pain severity and simultaneously increase the body temperature among elderly people with chronic pain.

Objective: The aim of this retrospective study was to evaluate and compare the changes in the pharyngeal airway (PA), maxillary sinus volume, and skeletal parameters after rapid maxillary expansion (RME) and alternate rapid maxillary expansion and constriction (Alt-RAMEC) followed by facemask (FM) therapy. Methods: The records of 40 patients with skeletal Class III malocclusion due to maxillary retrognathism were collected, and the patients were assigned into two groups. The first group comprised 8 male and 12 female patients (mean age, $10.0{\pm}1.1years$) treated using RME/FM for an average of 10 months. The second group comprised 10 male and 10 female patients (mean age, $9.64{\pm}1.3years$) treated using Alt-RAMEC/FM for an average of 12 months. Cone-beam computed tomography images acquired before (T0) and after treatment (T1) were evaluated. Results: Regarding the skeletal effects, significant differences between the groups were the increase in ANS-HRP (perpendicular distance of ANS to the horizontal reference plane, 0.99 mm, p <0.05) in the Alt-RAMEC/FM group and the decrease in PP-SN (palatal plane to Sella-Nasion plane, $0.93^{\circ}$, p < 0.05) in the RME/FM group. Maxillary sinus volumes increased significantly in both the groups, and the increase was statistically significantly higher in the Alt-RAMEC/FM group. Although no significant intergroup differences were observed in PA volumes, both lower ($1,011.19mm^3$) and total ($1,601.21mm^3$), PA volume increased significantly in the Alt-RAMEC/FM group. Conclusions: The different expansion devices and protocols used with FM therapy do not seem to affect the forward movement of the maxilla and PA volumes. In contrast, the increase in maxillary sinus volume was greater in the Alt-RAMEC/FM protocol.

In this report, we describe a case involving a 34-year-old woman who showed good treatment outcomes with long-term stability after multidisciplinary treatment for unilateral cleft lip and palate (CLP), maxillary hypoplasia, severe maxillary arch constriction, severe occlusal collapse, and gingival recession. A comprehensive treatment approach was developed with maximum consideration of strong scar constriction and gingival recession; it included minimum maxillary arch expansion, maxillary advancement by distraction osteogenesis using an internal distraction device, and mandibular setback using sagittal split ramus osteotomy. Her post-treatment records demonstrated a balanced facial profile and occlusion with improved facial symmetry. The patient's profile was dramatically improved, with reduced upper lip retrusion and lower lip protrusion as a result of the maxillary advancement and mandibular setback, respectively. Although gingival recession showed a slight increase, tooth mobility was within the normal physiological range. No tooth hyperesthesia was observed after treatment. There was negligible osseous relapse, and the occlusion remained stable after 5 years of post-treatment retention. Our findings suggest that such multidisciplinary approaches for the treatment of CLP with gingival recession and occlusal collapse help in improving occlusion and facial esthetics without the need for prostheses such as dental implants or bridges; in addition, the results show long-term post-treatment stability.

A chatbot is an interactive assistant that utilizes many communication modes: voice, images, video, or text. It is an artificial intelligence-based application that responds to users' needs or solves problems during user-friendly conversation. However, the current version of the chatbot is focused on understanding and performing tasks requested by the user; its ability to generate personalized conversation suitable for relationship-building is limited. Recognizing the need to build a relationship and making suitable conversation is more important for social chatbots who require social skills similar to those of problem-solving chatbots like the intelligent personal assistant. The purpose of this study is to propose a text analysis method that evaluates relationships between chatbots and users based on content input by the user and adapted to the communication situation, enabling the chatbot to conduct suitable conversations. To evaluate the performance of this method, we examined learning and verified the results using actual SNS conversation records. The results of the analysis will aid in implementation of the social chatbot, as this method yields excellent results even when the private profile information of the user is excluded for privacy reasons.

As research of oral history improved, not only public institutions but also private sectors actively collected and managed too. Despite these demands, however, there was not enough systematic analysis of systems targeted at oral archives. In this study, which started from this problem equation, the characteristics of oral archives and systems were analyzed and the institution that manages and serves current oral archives was selected to derive problems. It also analyzed the information required by the Presidential Archives, which collects oral archives but plans to build a system design. I will present suggestions for the establishment of a systematic oral archives management system focusing on problems and improvement measures that arise in the process.

Koryo Dynasty has greatly effected the meat eating practice in Korea. And by focusing on this period, this paper has in vestigated how this practice influenced and effected our meat eating culture. The 'Orders to Prohibit Butchery' written on Koryo's history books were to encourage stockbreeding rather than to follow the Buddhist policy they followed. By encouraging stockbreeding, they wanted to promote the usage of cattle in farming and thus increasing agriculture industry as a whole. Nonetheless, records show that hunting was permitted to a certain degree. And this allowed the civilians to depend their meat supply from hunting and for the fire field farmers to capture wild animals that harmed their crops. Moreover, through 'Kiwujae' (Kiwujae - a shamans service to pray for rain / ritual (praying) for rain.), we could see that earlier part of Karyo's rituals and ceremonies followed the Buddhist tradition while the latter followed the Shamanism tradition. Perhaps this was the result of allowing 'meat' for the service offerings. As Shamanism could be considered as a religion that allowed 'meat', prevalence of Shamanism was promoting meat-eating at mess(after these rituals and ceremonies that offered food (meat inclusive) to their guardian or god, the civilians would dine together.). In relation, this public eating practice slowed down the progress for storage technique. Therefore, meat-eating was developed through public and mass dining rather than through the form of family or private. On this account, we can safely regard meat-eating practice as a 'public event'. On the other hand, the history of castration is not so long in Korea. And the purpose of such practice was to use the stock for farming rather than to yield high quality meat. It is known that Mongol in Koryo period has greatly influenced meat cooking in Korea. And the exemplary dish is the 'tang' (tang - kind of soup. However less creamy, clearer broth and with more ingredients than soup.). However, the tang we ate in everyday life had the same cooking method as the tang we offered for services. Moreover, since we did not use castrated animals for our offering as the Mongolians, we must not have been greatly influenced by them. But if so, perhaps the influences would have been limited to the nobility.

Japanese economy suffered from a great recession for one decade between 1993 and 2002, because of the bubble bursting. Recently, a similar situation broke out in the USA and spread throughout the world. This paper investigated the effects of economic policy on the Japanese depression in order to find out how the recession, caused by financial crisis, can be reasonably removed. The analysis of documentary records indicate that there exists an optimum rate in government debt and the point in time of economic policy is decisive. Statistical studies with a VAR model and a State Space Model suggest that government expenditures affect the growth rate of national product but with a short term and it has a time lag of a half year. Income tax has a grievous negative effect on the growth rate with a long term and it works without a time lag. Therefore the increasing of taxation should be put into force very carefully. However private investment is a determinate factor for the recovery of depression.

Background: Moderate sedation is an integral part of dental care delivery. Target-controlled infusion (TCI) has the potential to improve patient safety and outcome. We compared the effects of using TCI to administer remifentanil/manual bolus midazolam with manual bolus fentanyl/midazolam administration on patient safety parameters, drug administration times, and patient recovery times. Methods: In this retrospective chart review, records of patients who underwent moderate intravenous sedation over 12 months in a private dental clinic were assessed. Patient indicators (pre-, intra-, and post-procedure noninvasive systolic and diastolic blood pressure, respiration, and heart rate) were compared using independent t-test analysis. Patient recovery time, procedure length, and midazolam dosage required were also compared between the two groups. Results: Eighty-five patient charts were included in the final analysis: 47 received TCI-remifentanil/midazolam sedation, and 38 received manual fentanyl/midazolam sedation. Among the physiological parameters, diastolic blood pressure showed slightly higher changes in the fentanyl group (P = 0.049), respiratory rate changes showed higher changes in the fentanyl group (P = 0.032), and the average EtCO₂ was slightly higher in the remifentanil group (P = 0.041). There was no significant difference in the minimum SpO₂ levels and average procedure length between the fentanyl and remifentanil TCI pump groups (P > 0.05). However, a significant difference was observed in the time required for discharge from the chair (P = 0.048), indicating that patients who received remifentanil required less time for discharge from the chair than those who received fentanyl. The dosage of midazolam used in the fentanyl group was 0.487 mg more than that in the remifentanil group; however, the difference was not significant (P > 0.05). Conclusion: The combination of TCI administered remifentanil combined with manual administered midazolam has the potential to shorten the recovery time and reduce respiration rate changes when compared to manual administration of fentanyl/midazolam. This is possibly due to either the lower midazolam dosage required with TCI remifentanil administration or achieving a stable, steady-state low dose remifentanil concentration for the duration of the procedure.
