The purpose of this study is to consider the characteristics of character's body-image throughout the on-line games and with this study we researched the symbolic meaning reflected by the character's body-images throughout the fashion. The characteristics of the body-images presented in modern fashion is expressed in 4 features on Lineage II game. First, it adopts the ways in which modern fashion expresses the erotic image and represents various sexual stimulation, which can not be represented in the real world, in cyberspace. Second, it expresses the beauty and taste in sensitivity by exchanging the items, which are the features of body-image, each other as the neutral body-image and pursuits for the double side feature between males and females by dismantling the point of view to sex. Third, it shows the new value system different from the existing one by using extraordinary items and materials that you've never seen in real fashion as the abnormal body-image expressed in informal and inaccurate principal of deformation. Fourth, it show the body with the items which induces more interest and curiosity than the real world do as the humorous body-image accompanying with childish amusement and pleasure.

Objectives & Methods : This study aims to investigate the application of the principle of the mutual communication between organ and bowel(臟腑相通) on Tong's acupuncture. We classified the frequently used Tong's acupuncture points according to the principle of the mutual communication between organ and bowel. Results & Conclusions : Considering the locations and indications of the most frequently used points among the 740 master Tong's acupuncture points, we could reach the following conclusions; 1. The chief virtues of 66 master Tong's acupuncture points could be explained by the principle of mutual communication between organ and bowel. 2. Among the relationships of mutual communication between organ and bowel, the most frequently applied relationship was relationship which applied to 16 master Tong's acupuncture points, and the , , , , and followed. 3. Considering the body regions, 13 out of 66 master Tong's acupuncture points which the relationship of mutual communication between organ and bowel was applied to, were located at the 1-1 region, and the same number at the U region, the others were at the 7-7, 3-3, 2-2, 4-4, 10-10, 6-6, 5-5 regions in the order of the number of the points, and none at the 9-9 region.

BACKGROUND: Groundwater is believed to possess many beneficial effects due to its natural source of various minerals. In this study, we examined the effects of natural Jeju groundwater S1 (Samdasoo$^{TM}$), S2 and S3 pumped up from different locations of Jeju Island, Korea, along with local tap water, on body weight gain, serum lipids and lipoproteins, and liver histopathology in high-fat diet-induced hyperlipidemic rats. MATERIALS/METHODS: Rats were randomly and equally divided into 6 groups. Different water samples were supplied to the hyperlipidemic rats as their daily drinking water and the widely-used anti-hyperlipidemic drug simvastatin was used as a positive control. Body weight, serum lipids and lipoproteins were measured weekly. Liver weight, liver index and liver histopathology were examined after the execution of the rats. RESULTS: After drinking Jeju groundwaters for two months, S2 but not S3 significantly reduced weight growth and serum triglycerides levels and increased high density lipoprotein-C (HDL-C) without affecting total cholesterol or LDL-C. S1 and particularly S2 significantly reduced the severity of liver hypertrophy and steatosis. All Groundwaters had much higher contents of vanadium (S3>S2>S1>>tap water) whereas S1 and S2 but not S3 markedly blocked autoxidation of ferrous ions. CONCLUSION: Jeju Groundwater S1 and particularly S2 exhibit protective effects against hyperlipidemia and fatty liver and hypothesize that the beneficial effect of Jeju Groundwaters may be contributed from blockade of autoxidation of ferrous ions rather than their high contents of vanadium.

Objective: This study aimed to assess the technical feasibility, efficacy, and safety of the safe triangular working zone (STWZ) approach applied in percutaneous vertebroplasty (PV) for spinal metastases involving the posterior part of the vertebral body. Materials and Methods: We prospectively enrolled 87 patients who underwent PV for spinal metastasis involving the posterior part of the vertebral body, with or without the STWZ approach, from January 2019 to April 2022. Forty-nine patients (27 females and 22 males; mean age ± standard deviation [SD], 57.2 ± 11.6 years; age range, 31-76 years) were included in group A (with STWZ approach), accounting for 54 vertebrae. Thirty-eight patients (18 females and 20 males; 59.1 ± 10.9 years; 29-81 years) were included in group B (without STWZ approach), accounting for 57 vertebrae. Patient demographics, procedure-related variables, and pain relief as assessed using the visual analog scale (VAS) were collected at different time points. Tumor recurrence in the vertebrae after PV was analyzed using Kaplan-Meier curves. Results: The STWZ approach was successful from T1 to L5 without severe complications. Cement filling was satisfactory in 47/54 (87.0%) and 25/57 (43.9%) vertebrae in groups A and B, respectively (p < 0.001). Cement leakage was not significantly different between groups A and B (p = 1.000). Mean VAS score ± SD before and 1 week and 1, 3, 6, 9, and 12 months after PV were 7.6 ± 1.8, 4.2 ± 2.0, 2.7 ± 1.9, 1.9 ± 1.5, 1.7 ± 1.4, 1.7 ± 1.1, and 1.6 ± 1.3, respectively, in group A and 7.2 ± 1.7, 4.0 ± 1.3, 3.4 ± 1.6, 2.4 ± 1.2, 1.8 ± 1.0, 1.4 ± 0.5, and 1.7 ± 0.9, respectively, in group B. Kaplan-Meier analysis showed a lower tumor recurrence rate in group A than in group B (p = 0.001). Conclusion: The STWZ approach may represent a new, safe, alternative/auxiliary approach to target the posterior part of the vertebral body in the PV for spinal metastases.

Objective : The aim of this study was to investigate the effect of tong's acupuncture on recovery of motor disorders in stroke patients. Methods : Twenty two patients with poststroke-hemiplegia were randomized into two groups. Ten patients(test group) treated by 2 methods-tong's acupuncture and body acupuncture. The other twelve patients(control group) treated only by body acupuncture. The activity of daily living was measured with a National Institutes of Health stroke scale(NlHSS) and Modified Barthel Index(MBI). The therapy was performed one a day for 2 weeks. Results: In terms of score of NIHSS. the test group showed statistically meaningful decrease after 2 week treatment. but the control group showed statistically meaningful decrease after I week(p<0.05). And in terms of score of MBI. the test group showed statistically meaningful increase after 2 week treatment. but the control group showed statistically meaningful increase after I week(p<0.05). There was no statistically meaningful difference after 1 and 2 week treatment between the groups. Conclusions: These results support that test group has almost same effectness compared with control group in improvement of the activity of daily living of poststroke-hemiplegic patients.

With the advancement and deployment of wireless communication techniques, wireless body area network (WBAN) has emerged as a promising approach for e-healthcare that collects the data of vital body parameters and movements for sensing and communicating wearable or implantable healthful related information. In order to avoid any possible rancorous attacks and resource abuse, employing lightweight ciphers is most effective to implement encryption, decryption, message authentication and digital signature for security of WBAN. As a typical lightweight cryptosystem with an extended sponge function framework, the PHOTON family is flexible to provide security for the RFID and other highly-constrained devices. In this paper, we propose a differential fault analysis to break three flavors of the PHOTON family successfully. The mathematical analysis and simulating experimental results show that 33, 69 and 86 random faults in average are required to recover each message input for PHOTON-80/20/16, PHOTON-160/36/36 and PHOTON-224/32/32, respectively. It is the first result of breaking PHOTON with the differential fault analysis. It provides a new reference for the security analysis of the same structure of the lightweight hash functions in the WBAN.

Subjects : We tried to analysis dermatosurgical prescriptions including 477 WonBang(元方) prescriptions for SangJungHaTong(上中下統) introduced by HwangDoYeon(黃道淵). Methods : Prescriptions in BangYakHapPyun(方藥合編) is generally categorized into SangTong(上統), JungTong(中統), HaTong(下統) which are called PoJe(補劑), HwaJe(和劑), KongJe(功劑) respectively. This study classified and analyzed major diseases and symptoms appeared in dermatosurgical prescription and composition of medicine, as well as in BangYakHapPyun(方藥合編). Results and conclusions : The results of examining dermatosurgical prescriptions in WonBang(元方) of SangJungHaTong(上中下統) in BangYakHapPyun(方藥合編) are as follows; 1. The proportion of dematosurgical prescriptions was SangTong(上統) $\frac{10}{126}$(7.9$\%$). JungTong(中統) $\frac{22}{181}$(12.1$\%$), and HaTong(下統) $\frac{16}{163}$(9.8$\%$), which means that JungTong(中統)(HwaJe 和劑) takes up relatively the largest portion. 2. As for SangTong(上統), upper level herbs used in medicine are Glycyrrhiza uralensis(甘草), Paeonia japonica(白芍藥), Angelica gigas(當歸). Astragalus membranaceus(황기). Ginseng(人蔘), Poria cocos(복령), Atractylodis macrocephalae rhizoma(白朮). Cinnamon(肉桂), Rehmaniniae radix preparat(熱地黃). And these herbs are the components of Sipjundaebo-tang(十全大補湯), one of the most well-known medicine for weak energy and blood(補氣血). 3. As for JungTong(中統), in addition to medicine for weak energy and blood. Ledebouriella seseloides(防風) that removes ill elements on skin surface and Pung(風) called "wind". Limonium tetragonum(桔梗) that eliminates discharges and sputum, Angelica dahurica(白芷) that removes discharge and suppress tumor are applied. Other herbs are Ostericum koreanum(羌活). Skullcap(황령),Schizonepeta tenuifolia(荊芥), Aurantii fructus(地殼), Cimicifuga heracleifolia(升麻), Bupleurum falcatum(柴胡), Lonicerae flos(金銀花). These herbs are more effective for wind-calming treatment. cooling down fever, clearing skin irritation, detoxication. removal of tumor and discharge than replenishing energy and blood. 4. As for HaTong(下統), Angelica gigas(當歸) and Ledebouriella seseloides(防風), the two major herbs for SangTong(上統) and JungTong(中統), are mostly used. In addition, Skullcap(黃芩), Gardenia jasminoides(梔子), Eisenia bicyclis(大黃) are other major components and their key efficacy is to lower fever and KongHa(功下). 5. Herbs applied for SangTong(上統), JungTong(中統), and HaTong(下統) in large quantity are Glycyrrhiza uralensis(甘草) that harmoniously combine different herbal elements and Poria cocos(복령) that discharges humidity and watery elements out of body, removes humid and hot elements, and strengthen gastrointestinal system. Based on this, it is inferred that prescriptions for this study focus largely on treatment of humid and hot elements. In the composition of this prescription, Angelica gigas(當歸), Paeonia japonica(白芍藥), and Cnidium officinale(川芎) are taking up relatively large proportion, which are basic herbs for Samul-tang(四物湯). Therefore, it is incurred here that the concept of "replenishing blood" bears importance in dermatosurgical treatment. 6. As for herb medicines used for more than two types of prescriptions of SangTong(上統), JungTong(中統), and HaTong(下統), most of them are simultaneously used for SangTong(上統) and JungTong(中統), or for JungTong(中統), and HaTong(下統) except for Atractylodis macrocephalae rhizoma(白朮) and Gleditsia sinensis(조각자). This finding implies that prescription or treatment that are simultaneously applied are replenishing and harmonizing, or harmonizing and attacking while replenishing and attacking never go together.

This study has been carried out to investigate the cause, pathological mechanism and treatment of symptoms regarded as the ischemic heart disease in Nei-jing(內經). I've got the following conclusions. 1. From the side of xing-bi(胸痺), the ischemic heart disease(IHD) was caused by that the energy in one's heart wasn't extended in the way of Yin-xie(飮邪), namely waste matter of human body and symptoms and treatment wern't written. 2. From the side of xin-bi (心痺), HID was catched by the mechanisms that the blood vessel is blocked. or the heart's blood was deficient owing to the mutation of mo-bi(脈痺), the lack of yang-ming(陽明) and excessive thoughts and worry and others. The symptoms were feeling oppressed in one's brest, palpitating, sudden dyspnea, the dryness of thorat, frequent belching and the fear by the inverse flow of the energy(氣). The treatment was that the yin(陰) was cured immediately, but the yang(陽) mustn't be attacked. 3. From the side of xing-tong(心痛), IHD was suffered from by mechanisms that following the han-sa(寒邪), namely the cold makes a invasion on humanbody, the vessel was blocked, spasm, filled and the amount of blood flow was poor, or caused by injury of vessel, the inverse flow and the disease of shi-dong(是動病) of shou-shao-xin-jing(手少陰心經) and so on. The pain was cramped into the upper and lower back or lower abdomen or throat and accompanied with nausea, abdominal dropsy, constipation, the impending of breathing and so on. The cure was mainly that acupuncture was applied at the jin-su(筋縮) region or meridian in relation to symptoms, but if the pain were severe, acupuncture mustn't be applied. The prog nosis was worse. 4. From the side of xing-tonge(心痛), IHD was divided into zhen-xing-tong(眞心痛) and jue-xing-tong(厥心痛), but pi-xiog-tong(脾心痛) and wei-xing-tong(胃心痛) out of jue-xing-tong(厥心痛) also included the symptoms of the digestive disease.
