Classifying vegetables recorded in Sikgamchalyo of Jeongjoji of Limwonsibyukji and Tangaekpyeon of Donguibogam and comparing the types features, efficacy and side effects based on Kimi Theory(氣味), we found forty one leafy vegetables, six root vegetables, nine fruit vegetables, nine mushrooms, seven seaweeds and two other vegetables in Limwonsibyukji and thirty five leafy vegetables, eight root vegetables, eight fruit vegetables, one mushroom, two seaweeds and one another vegetable in Donguibogam. According to the literature, vegetables are classified by five conditions(五氣) and five tastes(五味) and many are cold with sweet and bitter taste or warm with hot taste. They are efficacious in protecting the five viscera, building up energy, controlling heat, calming febrile diseases, promoting urination and excretion, calming cholera morbus, improving skin condition, calming the stomach, neutralizing poisonous effects and improving eyesight. To help prevent and cure diseases, those with cold physical constitution must take warm vegetables to vitalize their physiology and those with hot physical constitution cold vegetables for balance. To improve their physical health, our ancestors tried to control their bio rhythm with food and medicinal material and promoted health and prevented diseases by taking such food. We therefore expect that we can have a healthy dietary life by taking advantage of the five conditions and five tastes of vegetables and continuing the spirit of Yacksikdongwon(藥食同源).

Trigeminal neuralgia is a condition associated with severe episodic lancinating facial pain subject to remissions and relapses. Trigeminal neuralgia is often associated with blood vessel cross compression of the root entry zone or more rarely with demyelinating diseases and occasionally with direct compression by neoplasms of the posterior fossa. If initial medical management fails to control pain or is associated with unacceptable side effects, a variety of surgical procedures offer the hope for long-lasting pain relief or even cure. For patients who are healthy without significant medical co-morbidities, direct microsurgical vascular decompression [MVD] offers treatment that is often definitive. Other surgical options are effective for elderly patients not suitable for MVD. Percutaneous retrogasserian glycerol rhizotomy is a minimally invasive technique that is based on anatomic definition of the trigeminal cistern followed by injection of anhydrous glycerol to produce a weak neurolytic effect on the post-ganglionic fibers. Other percutaneous management strategies include radiofrequency rhizotomy and balloon compression. More recently, stereotactic radiosurgery has been used as a truly minimally invasive strategy. It also is anatomically based using high resolution MRI to define the retrogasserian target. Radiosurgery provides effective symptomatic relief in the vast majority of patients, especially those who have never had prior surgical procedures. For younger patients, we recommend microvascular decompression. For patients with severe exacerbations of their pain and who need rapid response to treatment, we suggest glycerol rhizotomy. For other patients, gamma knife radiosurgery represents an effective management strategy with excellent preservation of existing facial sensation.

Purpose: The focal ossification of auricular cartilage is an unusual clinical entity in which the ear becomes partially or totally rigid and immalleable. This condition may result from cold injury, local trauma, inflammation, or various systemic diseases. Patients may feel mild discomfort, but there are usually no other serious symptoms. We present a case of focal ossification of auricular cartilage in which the cause is unknown. Methods: A healthy 58-year-old man presented with a 2-year history of hard mass of right posterior auricular area. He denied any precipitating historical events like cold injury and inflammation. Routine testing did not demonstrate systemic abnormalities. Ultrasonographic examination revealed a $22{\times}10{\times}11mm$ sized heterogenous isoechoic mass showing an acoustic shadow. Results: Excisional biopsy was performed under local anesthesia. Histological examination revealed the ossification with deposition of trabecular bone in normal elastic cartilage. The patient was healed without any problems and satisfied with the result. Conclusion: We report clinical experience of focal ossification of auricular cartilage, which is quite a rare clinical entity. It should be considered that there is the possibility of ossification of cartilage when it meets the benign mass of the ear.

This clinical case report describes the digital workflow that combines a face scan, cone beam computed tomography and an intraoral scan to visualize the outcome of prosthodontic treatment in the anterior region. This approach improves communication between clinic, laboratory and patients. A patient with healthy general condition came for a restorative treatment to treat post-traumatic central incisors of maxilla. A virtual patient replica was made by incorporating a face scan, cone beam computed tomography and an intraoral scan. Design mockup of definitive restorations was shown to the patient and modified according to the patient's desire. This digital workflow facilitates the fabrication of optimal esthetic restorations, and enhances the predictability of outcome of restorations.

The decrease in fatness of the Pacific oyster Crassostrea gigas, which consequently results in decrease in the profit of aquaculture industry, has become a source of serious concern in southeast coast of Korea. The ratio of flesh (edible portion) to total oyster weight, commonly called edible portion yield ("suyul" in Korean), have been used as a fatness index for the healthy and valuable state of oyster from the early stage of oyster farming in Korea. More than 360 data sets were collected from early culturing periods (in the 1970s) to the present from approximately 15 published literatures to evaluate the long-term fatness trend of oyster, reared particularly in submerged longline culturing system in Gyeongsangnam-do province. Slight decrease in oyster fatness during the 1970s to 1990s was detected in Tongyeong and Geoje Bays; however, from the 1990s to the present, clear decreasing trends were observed with a decrease of 0.04-0.08% year^-1, especially during harvest season. Oyster mass production per unit area almost doubled within a short period in the early 2000s; however, changes in coastal environment factors inhibited the fattening of shellfish from the mid 1990s. These results indicate that the severe competition in feeding and low biological production in water column might be some convincing reasons for the decrease in fatness of oyster from the 1990s, in Tongyeong and Geoje Bays, Korea.

Purpose: To determine whether responses to serotonin are altered in bladder strips from cats diagnosed with a naturally occurring form of bladder pain syndrome/interstitial cystitis termed feline interstitial cystitis (FIC). Methods: Full thickness bladder strips were isolated from aged matched healthy control cats and cats with clinically verified FIC. Bladder strips were mounted in an organ bath and connected to a tension transducer to record contractile activity. A serotonin dose response ($0.01-10{\mu}M$) was determined for each strip with the mucosa intact or denuded. Results: Bladder strips from control and FIC cats contracted in response to serotonin in a dose-dependent manner. The normalized force of serotonin-evoked contractions was significantly greater in bladder strips from cats with FIC (n=7) than from control cats (n=4). Removal of the mucosa significantly decreased serotonin-mediated responses in both control and FIC bladder preparations. Furthermore, the contractions in response to serotonin were abolished by $1{\mu}M$ atropine in both control and FIC bladder strips. Conclusions: The effect of serotonin on contractile force, but not sensitivity, was potentiated in bladder strips from cats with FIC, and was dependent upon the presence of the mucosa in control and FIC groups. As atropine inhibited these effects of serotonin, we hypothesize that, serotonin enhances acetylcholine release from the mucosa of FIC cat bladder strips, which could account for the increased force generated. In summary, FIC augments the responsiveness of bladder to serotonin, which may contribute to the symptoms associated with this chronic condition.

Purpose. This study was conducted to analyze fatigue and subjective oral health status in the employees in educational institutions and provide basic data for the development of a program for the promotion of oral health. Methods. As for the subjects, this study conducted a survey with 468 educational personnel in elementary, middle, and high schools in the Daegu-Gyeongbuk area from March through June 2016 and utilized 407 copies finally. As for the items on the survey, this study conducted an investigation on their general characteristics, fatigue, and subjective oral health status(halitosis, xerostomia, temporomandibular disorder) with the self-administered method. With the data collected, this study conducted frequency analysis, t-test, ANOVA, and multiple regression analysis, using SPSS 20.0 statistical program, and the statistical significance level was .05. Results. As a result of this study, it turned out that by sex, fatigue was higher in women(4.59 points); by the place of work, those in 'elementary school' had higher fatigue(4.59 points); and by health condition and oral health status, most of them responded that they were 'not healthy'(4.81 and 4.84 points, respectively) and there was a statistically significant difference (p<.05). As for the correlation between fatigue and subjective oral health status, there were positive(+) impacts on halitosis(=.248, p<.001), xerostomia(=.097, p<.05), and temporomandibular disorder(=.148, p<.01), so it turned out that there was a correlation between fatigue and subjective oral health status. Conclusion. Based on the result of an analysis of the impacts of the fatigue level on subjective oral health status, it is judged that it would be necessary to continue to build up a program that can promote the oral health status of the educational personnel. In addition, it is necessary to conduct studies continuously for the development and application of a program for the change in lifestyle and behavior that can lower their fatigue.

Background: Dementia is a condition in which a person who has been living a normal life suffers from various cognitive impairments in memory, words, and judgment that considerably disrupt daily life. The oral care ability and subjective oral status of elderly individuals with dementia are lower than those of a healthy person. The oral health care of individuals admitted to nursing homes inevitably falls to nursing assistants and nursing care staff. This study aimed to investigate the need for oral health management items of and to provide basic direction for the future of the Dementia National Responsibility System. Methods: Elders aged 65 years and over were selected from a comprehensive welfare center. A total of 155 questionnaires were analyzed. The questionnaire consisted of 15 items about general status, 9 items about recognition of the Dementia National Responsibility System, 5 items of the subjective recognition of oral health, and 6 items of the correlation between oral health and dementia. Results: Among our subjects, 71.0% answered that they did not know about the Dementia National Responsibility System, 78.7% answered that they think they need the system, and 81.9% think that they should add dental health items to the Dementia National Responsibility System. The response to the need for dementia national responsibility, oral health items in the Dementia National Responsibility System, and oral specialists all showed scores of >4 points. The need for the Dementia National Responsibility System, oral health items, and specialists were found. Conclusion: It is necessary to include oral health care items in the Dementia National Responsibility System so that elderly individuals with dementia can receive the needed oral health care.

This study was carried out to investigate benthic sedimentary environments and benthic polychaetous communities on the coast of Ulsan, located on the southern East Sea of Korea. This survey was conducted at 15 stations, four times seasonally in January, April, July and October 2016. From the coast to the outer sea, surface sediments turned into fine grained sediments. There were complex coarse-grained sedimentary facies in various forms in the coastal zones while those with mud facies were found in the offshore zone. Organic matter content (LOI) and sulfide amount (AVS) recorded extremely high values, and increased from the coast to the outer sea, showing a similar trend to mud content with depth. The benthic polychaetous community revealed a mean density of $525ind./m^2$, and the total species number of species was 84. The major dominant polychaetous species were Magelona japonica, Lumbrineris longifolia and Heteromastus filiformis throughout the four seasons. Magelona japonica was concentrated predominantly in shallow coastal areas, but was present in all the regions of the survey area. Lumbrineris longifolia showed higher density in offshore regions more than 30 m deep, whereas H. filiformis showed higher density in coastal areas less than 30 m in depth. As a result of cluster analysis, the study area was divided into three ecological areas according to species composition, such as the northern coastal area between Ulsan PortOnsan Port, the southern area around Hoeya River and the outer sea area. Benthic environments in the study area, as determined by AMBI and BPI index, maintained a healthy condition in all four seasons with the AMBI at a level above GOOD and BPI at a level above FAIR. As organic matter accumulation continues to take place in the Ulsan coastal area, it is essential that detailed research activities continue to be carried out and ongoing monitoring be maintained.

PURPOSE: This study examined the dynamic range of motion (ROM) of the hip, knee, and ankle joint when wearing different shoe sole lifts, as well as the limb asymmetry of the range according to the leg length discrepancy (LLD) during normal speed walking. METHODS: The participants were 40 healthy adults. A motion analysis system was used to collect kinematic ROM data. The participants had 40 markers attached to their lower extremities and were asked to walk on a 6 m walkway, under three different shoe lift conditions (without an insole, 1 cm insole, and 2 cm insole). Visual3D professional software was used to coordinate kinematic ROM data. RESULTS: Most of the ROM variables of the short limbs were similar under each insole lift condition (p>.05). In contrast, when wearing a shoe with a 2 cm insole lift, the long limbs showed significant increases in flexion and extension of the knee joint as well as; plantarflexion, dorsiflexion, pronation, eversion, and inversion of the ankle joint (p<.05). Of the shoes with the insole lifts, significant differences in all ROM variables were observed between the left and right knees, except for the knee internal rotation (p<.05). CONCLUSION: As the insole lift was increased, more ROM differences were observed between the left and right limbs, and the asymmetry of the bilateral lower limbs increased. Therefore, appropriate interventions for LLD are needed because an artificial mild LLD of less than 2.0 cm could lead to a range of musculoskeletal problems of the lower extremities, such as knee and ankle osteoarthritis.
