  • Objectives : The purpose of this study was to fix the synonyms, origin, formation mechanism, description, and efficacy of Hwangnapchim in Elucidation of Materia Medica. Methods : Through searching histories and herbal classics, We categorized the contents, and compared with Aquilariae Lignum Resinatum. Results : The synonyms of Hwangnapchim were classified by 3 categories : Napchimhyang-type, Ganamhyang-type and Ginamhyang-type. In early period, it was called by Napchimhyang-type, named after its description that was similar to beeswax. Afterward it was called by Ganamhyang-type or Ginamhyang-type, because of the name "Kynam" that was called by in its producing region. And there were records of producing region of Vietnam, Cambodia, and being from abroad, while those of Vietnam were most frequent. According to custom duties of Ming Dynasty, Hwangnapchim was 17.5 times as expensive as Agarwood. Hwangnapchim shared main producing region, original plant, and process of formation with Agarwood. Therefore, its original plant was Aquilaria crassna, but added honey during formation process. Hwangnapchim was classified 5 types according to its description, the highest quality was Yu-gyeol, resembled beeswax, and easily recovered if get a scar. Hwangnapchim had a fragrance at room temperature, a spicy flavor, and the efficacy of blocking urine and feces. Conclusions : These results showed that Vietnam was major producing area of Hwangnapchim, and that it shared same origin with Agarwood, but it had different description, efficacy, and higher prices because of being added honey during formation.

  • Objects : This study aimed to identify the origin species of Ulmi Cortex and Ulmi Semen Pasta. Methods : I searched for different types of 'Yu(楡)' from Zhong Xiu Zheng Huo Jing Shi Zheng Lei Bei Yong Ben Cao (重修政和經史證類備用本草) of the Song Dynasty, then compared the descriptions of Yu with real life species. Items that were inconsistent were sequentially deleted to finally find the original species that satisfies all conditions. Results : There were five types of Yu : Jiyu(地楡), Jayu(刺楡), Langyu(郞楡), Goyu(姑楡), and Baekyu(白楡). Jiyu was Sanguisorba officinalis or Sanguisorba officinalis var. longifolia which was a herb. Jayu was Hemiptelea davidii (Hance) Planch. which had thorns on its branches. Ulmus laciniata had leaves that split into three branches. Langyu was Ulmus parvifolia which beared fruit in the fall. For these reasons, the four items above were ruled out. The fruit of Goyu was Ulmi Semen Pasta, which was the largest among fruits and was therefore Ulmus macrocarpa. The fruit of Baekyu was Yuhyup(楡莢) and the ancient coin Yuhyupjeon(楡莢錢) was resembled Yuhyup. The normal pulse of the lung resembled the appearance of falling Yuhyup. The peel of Baekyu was Yubaekpi(楡白皮), and when it was removed from coarse bark, contained an abundance of white sap; the place where this sap overflowed on the stem bark was white, therefore Baekyu was identified as Ulmus pumila. Conclusions : From the results above, the origin species of Ulmi cortex was Ulmus pumila and the origin species of Ulmi Semen Pasta was Ulmus macrocarpa.

  • The present study investigated the relationship among the level of family differentiation, quality of family relationship, and intimacy with their partners in 381 adult children. First, this study examined the relationship between the level of family differentiation and quality of family relationship. The result showed that the level of family differentiation was positively and significantly correlated to quality of family relationship. This finding indicated that family differentiation may be used for an objective and useful index to measure the dynamics of emotional system and the level of family-of-origin emotional health. Second, the influence of the family of origin was studied through exploring the relationship between the level of differentiation of family of origin, and adult children's intimacy with their partners. It was found that the family differentiation level was positively and significantly related to adult children's intimacy with their partners at each subsystem, but family differentiation levels of parents more influenced on adult male's intimacy than on adult female's intimacy with their partners.

  • At local, galaxy properties are well known to be clearly different in different environments. However, it is still an open question how this environment-dependent trend has been shaped. In this presentation, we will show the results of our investigation about the evolution of star-formation properties of galaxies over a wide redshift range, from z~2 to z~0.5, focusing its dependence on their stellar mass and environment. In the UKIDSS/UDS region, we estimated photometric redshifts and stellar population properties, such as stellar masses and star-formation rates, using the deep optical and near-infrared data available in this field. Then, we identified galaxy cluster candidates at z~0.5-2. Through the analysis and comparison of star-formation (SF) properties of galaxies in clusters and in field, we found interesting results regarding the evolution of SF properties of galaxies: (1) regardless of redshifts, stellar mass is a key parameter controlling quenching of star formation in galaxies; (2) At z<1, environmental effects become important at quenching star formation regardless of stellar mass of galaxies; and (3) However, the result of the environmental quenching is prominent only for low mass galaxies (M* < $10^{10}M_{\odot}$) since the star formation in most of high mass galaxies are already quenched at z > 1.

  • Objective : Sometimes a vertebral artery (VA) enters the spinal canal via the C1-2 intervertebral space, a variation regarded as a C2 segmental-type VA. This paper describes the anatomy of the C2 segmental-type VA and reviews its clinical importance. Methods : Between March 2014 and November 2015, 3386 patients underwent computed tomographic angiography. I identified C2 segmental-type VAs, associated vascular variation, the origin of ipsilateral posterior inferior cerebellar arteries (PICAs), and the clinical symptoms associated with C2 segmental-type VAs. The origin of an ipsilateral PICA is divided into 5 types. A type 1 PICA originates from ipsilateral VAs coursing suboccipitally (IVASO), a type 2 originates from ipsilateral proximal C2 segmental-type VAs, a type 3 originates from ipsilateral distal C2 segmental-type VAs. For type 4, the PICA does not originate from an ipsilateral VA. For type 5, the PICA is the terminal end of an ipsilateral C2 segmental-type VA. Results : One hundred thirteen patients had 121 C2 segmental-type VAs; 47 were associated with an IVASO, and 74 were not. Four type 1, 13 type 2, 60 type 3, 42 type 4, and two type 5 PICAs were identified. Only one patient showed symptoms associated with a C2 segmental-type VA, being a 71-year-old man presenting with a C2 segmental-type VA infarction. Conclusion : For C2 segmental-type VAs, the ipsilateral IVASO and origin of the PICA are important for predicting the outcome of this type of VA infarction.

  • This study examined hwangbek dyeability for cotton, silk, and wool from different tree species and origin as well as their berberine and palmatine content. A total of 12 different hwangbek were examined, six purchased directly from different locations of China and six purchased from the Seoul Medicine Market. Hwangbek purchased from China were 3 Kwanhwangbek (Phellodendron amurense Rupr.) from Jilin, Liaoning, Heilongjiang and 3 Chunhwangbek (Phellodendron chinense Schneid.) from Sichuan, Yunnan, and Guangxi. Hwangbek purchased from the Seoul Medicine Market included 3 hwangbek that originated from Korea and 3 hwangbek imported from China. We extracted 2.5g of each hwangbek into 500mL of water for 60 min at $80^{\circ}C$. Dyeing was conducted using the IR dyeing machine for 30min at $55^{\circ}C$ using a 1:100 liquor ratio. Cotton was mordanted using tannic acid followed by potassium antimonyl tartrate trihydrate treatment before dyeing. Berberine and palmatine pigments in hwangbek were identified with the HPLC-DAD-MS instrument and the amount of pigment was quantified using an ion chromatogram. The results indicated that the K/S values of dyed fabrics were highly related to the amount of pigment in hwangbek used for dyeing.
