  • Although Traditional Korean Medicine had always referred to Mamok(痲木: Paresthesia) as the prodrome of stroke for a long time, yet there were only few research papers on it. Hence, the purpose of this research is to explore the relationship between Mamok(痲木; Paresthesia) as the prodrome and an attack of stroke. Setting 509 Korean impatient women as the subject of research, 264 of the whole are stroke patients and 245 are non-stroke patients. Blood tests, questionnaires, and body measurements (height, weight, waist, hip) are performed to the subjects. Basic population traits, life-style, and past history are included in the contents of questionnaires. whether or not they have experience the numbness, description about the clinical characteristics of the symptom, the body parts which the symptom occurred, the onset of the symptom, and the incidences are examined in the category inquiring the numbness of the hand and foot. After adjusting for age, unilateral numbness was associated with significantly increased risk of stroke. When adjusted for other factors(Half of WHR, History of Hypertension and Diabetes mellitus, Cigarette smoking, Alcohol drinking, Education, Marital status, Regular exercise), the risk of stroke was positively associated with unilateral numbness.(Age Adjusted Odds Ratios=2.282(95%CI=1.107-4.705), Multivariate Odds Ratios=4.105(95% CI=1.233-13.671)) Whereas no significant association was observed in the onset and the incidence of unilateral numbness. This study suggest that preceding Mamok(痲木; paresthesia) before stroke attack is may be common prodrome symptoms of stroke. Prospective cohort study on the association between Mamok(痲木;Paresthesia) as the prodrome and an attack of stroke in Korean population will be necessary.

  • In spite of the increasing significance on a scale of building measurement unit and its system having been used in many areas of architecture, only a few researchers carried out the studies on a specific period. It is even harder to find a research results dealt in view of architecture. This research gives a focus on different types of scales employed in the ancient buildings and their sites, based on the research results of unit scale or scales found in recent excavations. After the review of literature on the scales widely used in the ancient times and of the various types of scales excavated archeologically, a kind of scale unit system that had been widely and extensively employed throughout the period of 'Three Kingdoms' could be revealed. The scale system is possibly able to be applied to estimate the exact scale of buildings and their sites as well in that era. The research results show that the scale and its system employed in the East and West buildings and their sites of 'Kum-dang' in 'Mi-ruk Sa' temple are different from 'Kokuryo' scale that was believed in to be used in the temple. Contrary to the suggestion by excavation report on the type of scale employed in the buildings their sites, a scale of 29 centimeters, similar to that of Tang, was employed. It was also found that one module consists of three 'Chuk's of 88.8 centimeters. Based on this scale system, we could conclude that three modules of the buildings on the front and two and half modules of them on the sides were explained by this scale and its system.

  • Background: The expression of MMP genes has been demonstrated to be associated with tumor invasion, metastasis and survival rate for a variety of cancers. The functional promoter polymorphism MMP-2 C-735T is associated with decreased expression of the MMP-2 gene. The aim of present study was to detect any association between MMP-2 C-735T and susceptibility to breast cancer. Materials and Methods: The MMP-2 C-735T polymorphism was studied in 233 women (98 with breast cancer and 135 healthy controls). All studied women were from Kermanshah and Ilam provinces of Western Iran. The MMP-2 C-735T polymorphism was detected using a polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. Results: The frequencies of MMP-2 CC, CT and TT genotypes in healthy individuals were 59.3, 38.5 and 2.2%, respectively. However, in breast cancer patients, only CC (71.4%) and CT (28.6%) genotypes were observed (p=0.077). In patients the frequency of the MMP-2 C allele was significantly higher (85.7%) compared to that in controls (78.5 %, p=0.048). The presence of C allele of MMP-2 increased the risk of breast cancer by 1.64-fold [OR=1.64 (95%CI 1.01-2.7, p=0.049)]. The frequency of MMP-2 C allele was also higher in patients ${\leq}40$ years (88.9%) than those aged ${\geq}41$ years (67.5%, p=0.07). In addition, the frequency of MMP-2 C allele tended to be higher in patients with a family history of cancer in first-degree relatives (76.6%) compared to that without a family history of cancer (67.3%, p=0.31). Conclusions: Our findings indicate that the C allele of MMP-2 C-735T polymorphism is associated with increased risk of breast cancer. Also, the MMP-2 C allele might increase the risk of young onset breast cancer in our population.

  • These days, fashion museums that were established during the 60~70s in advanced countries are spiritedly planning opportune exhibitions as well as opening collections and accumulated research materials to the public. They are also publishing innovative visual references and offering various educational programs. They play a crucial role in speeding up the development of creativity of fashion designers by accumulating archives through analytic researches. Since Korea has applied western fashion for over a century, now is the time to make a fundamental long-term plan for establishing the identity of Korean fashion by gathering and classifying the history of a century. Thus, the aim of this study is to reach a conclusion to construct fashion museum in Korea to discover as well as develop fashion talents and eventually enhancing national competitiveness. First, the theoretical study on the history and the functions of fashion museum were analysed. 'The collection & exhibition' in the common thread is one function of the fashion museum. Another function is 'the research', which includes accumulations, classification and record of materials in a particular point of view. It also includes publishing catalogues with temporary exhibitions and open management to the scholars and the designers. 'The communication', which is enacted through various educational programs and events for inflow of new visitors, is the other function of fashion museum. The current state of fashion museums in advanced countries and Korea were also analysed. Korean public museums only owned traditional collections while public fashion museums in other advanced countries usually owned collection of the past and the present together. The only contemporary fashion museum in Korea is run private which leads to many problems. Finally, The study went further to suggest the advanced model of fashion museum in Korea based on the research.

  • BACKGROUND/OBJECTIVES: Low early pregnancy serum 25-hydroxy vitamin D (25[OH]D) levels can increase gestational diabetes mellitus (GDM) risk, although inconsistent findings related to that association have been reported. This study examined the association of serum vitamin D with GDM and the possible influencers on this association. SUBJECTS/METHODS: This study included 259 pregnant women within the Seremban Cohort Study (SECOST). Blood samples at < 14 weeks of gestation were drawn to determine serum 25(OH)D levels. GDM diagnosis was made at 24 to 32 weeks of gestation using a standard procedure. Association between serum vitamin D and GDM was tested using binary logistic regression. RESULTS: Nearly all women (90%) had mild (68.3%) or severe (32.2%) vitamin D deficiency (VDD). Non-GDM women with mild VDD had a significantly higher mean vitamin D intake than GDM women with mild VDD (t = 2.04, p < 0.05). Women with higher early pregnancy serum vitamin D levels had a greater risk of GDM. However, this significant association was only identified among those with a family history of type 2 diabetes mellitus (T2DM) and in women with a body mass index indicating overweight or obese status. CONCLUSIONS: The high prevalence of VDD in this sample of pregnant women underscores the need for effective preventive public health strategies. Further investigation of this unexpected association between serum vitamin D level and GDM risk in predominantly VDD pregnant women and the potential effects of adiposity and family history of T2DM on that association is warranted.

  • Objectives: The study examines the relation between urinary arsenic concentration and blood pressure, which is a risk factor of cardiovascular disease. Materials: In this study, the urinary arsenic concentration, history of diagnosed disease, and blood pressure of 782 local residents in Gwangyang, Yeosu, and Hadong regions from May 2007 to July 2007. Results: The urinary arsenic concentration of total participants was $9.06{\mu}g/g-ct$. The logistic regression analysis of medical diagnosed history and urinary arsenic concentration, showed statistically significance (p<0.05) of high urinary arsenic concentration in participants with diagnosed hypertension. In addition, diagnosed hypertension it was observed that the high blood pressure was related with the pulse pressure. Conclusions: The arsenic concentration level was low in this study, but the exposure to low levels of arsenic has an effect on hypertension. Also, hypertension is related to pulse pressure and mean arterial blood pressure as well as being risk factor of cardiovascular disease. Therefore, close supervision of low -level arsenic exposure is needed.

  • Cryptic species complexes are increasingly recognized in phycological research, obscuring taxonomy and raising questions about factors influencing speciation. A recent exploration of kelp genetic diversity on Haida Gwaii, British Columbia revealed the existence of a new species, Saccharina druehlii, which is cryptic with Saccharina sessilis. This suggests that molecular investigations further north may be required to elucidate the taxonomy and evolutionary history of this lineage. Although, for several decades, S. sessilis was considered a single highly variable species, its taxonomy has been far from straightforward. In particular, Hedophyllum subsessile (Areschoug) Setchell is now recognized as a synonym of S. sessilis in North America, but as a growth form of Saccharina bongardiana in Far East Russia. To resolve this taxonomic confusion, we sequenced mitochondrial (CO1-5P) and nuclear (internal transcribed spacer) markers of S. sessilis populations from the Aleutian Islands, Alaska, USA. Interestingly, none of our sequences matched S. sessilis sensu stricto. Instead, CO1-5P sequences from populations in the central and eastern Aleutians matched exactly S. druehlii with increasing sequence divergence occurring westward. Samples from Attu, the western-most island, composed a genetic group that clearly represents Kjellman's concept of Hafgygia bongardiana f. subsessilis and is distinct enough from S. druehlii and S. sessilis to potentially constitute a distinct species. Therefore, Saccharina subsessilis comb. nov. is proposed for this entity. Our results suggest the existence of a species complex at the crown node of S. sessilis and thus further investigation of Saccharina in Alaskan waters should be conducted to reconstruct the evolutionary history of this fascinating lineage.

  • Two dogs (Case 1: Poodle, 4 years old, spayed female; Case 2: Bulldog, 3 years old, intact female) were referred to us for treatment of vomiting; Case 1 had a history of acute vomiting that started 1 day prior to presentation, and Case 2 had a history of chronic vomiting that started 2 years prior to presentation. The vomiting did not respond to medication in the local animal hospital. Results from abdominal ultrasound examinations showed that case 1 had gastric wall thickening, and case 2 had no remarkable findings. For both cases, we performed gastrointestinal endoscopic examinations, and several biopsy samples were obtained from different gastric areas. On the basis of the results of histopathological examinations, both dogs were diagnosed with atrophic gastritis concurrent with a Helicobacter infection. Clinical signs improved after antibiotic therapy. This case report describes the clinical, endoscopic, and histopathological findings of atrophic gastritis concurrent with a Helicobacter infection.

  • Recently, cultural heritages in South Korea gain many interests of restoration and preservation from the government since many of that have been severely damaged during earthquakes. Many previous studies in both terms of experimental and analytical approaches have been done to examine structural behavior and decide appropriate methods of preservation. Being motivated by such researches, this research aims to investigate a religious stone pagoda dated back to the Goryeo Dynasty in Korea. The structure consists of a granite stone foundation and baked bricks, which resembles the shape of traditional pagodas. In order to examine the structural behavior of the pagoda, an analytical model is implemented using ANSYS, a comprehensive engineering simulation platform. For the time history analysis of the pagoda, several earthquake excitations are chosen and input to simulation modeling. Seismic response of the tower such as time domain, natural frequency, modal shapes and peak acceleration measured at each layer are presented and discussed. In addition, the amplification ratio of the tower is calculated from the accelerations of each layer to determine tower stability in accordance with Korean seismic design guide. The determination and evaluation of status and response of the brick tower by simulation analysis play an important role in the preservation of history as well as valuable architectural heritages in South Korea.

  • Background: This study investigated current research trends in bee venom acupuncture in Korea. Materials and methods: The literature in Korea was reviewed using the search engines Science and Technology Society Village, Korean Studies Information Service System, National Discovery for Science Leaders, and Oriental Medicine Advanced Searching Integrated System. The keywords searched were "bee venom," "apitoxin," "apitherapy," and "bee sting." We selected 412 studies, which included Korean literary studies, experimental studies, and clinical studies. Results: We classified them by publication year, research type, disease and topic, and quality assessment. Among bee venom-related studies, clinical studies (235 studies) outnumbered experimental studies (149 studies) and literary studies (28 studies). Nineteen experimental studies concentrated on the theme of "anticancer." In the type analysis of clinical studies, lumbar disorders comprised 45 of 235 studies, followed by the effect on body. Forty-two randomized controlled trials (RCTs) have been published from 2003 to date (2015). Twenty-two studies used appropriate randomization methods. Fourteen studies had a Jadad score of 4-5 points; 15 studies, 1-3 points; and 13 studies, 0 points. Conclusions: Bee venom treatment is based on Korean traditional medicine theory. Numerous research studies suggest its effectiveness. Effort and academic approach on bee venom are expected to receive a positive evaluation.
