In 2019, the first excavation survey was conducted at the Temple Site No. 4 of Yaksugok Vally in Namsan Mountain, Gyeongju to determine the original location of the headless stone Buddha statue and the structure of the temple site. The survey excavated a stone Buddha head that was confirmed in a comparative analysis to be petrologically and mineralogically identical to a headless stone seated Buddha statue found derelict nearby. Traces of gold leaf and black adhesive were found on a portion of the right side of the face of the Buddha head buried in the ground. Since it is exceedingly rare for lacquer and gilding techniques to have been applied to a large stone Buddha statue without a base layer, this study examines the gilding techniques of the time by analyzing the characteristics of the materials used. In this process, the structure of the gold foil was observed through analytical microscopy and scanning electron microscopy with energy dispersive X-ray spectrometry, and the gold (Au) component was identified. As a result of analyzing the black adhesive using pyrolysis-gas chromatograph/mass spectrometry (pyrolysis-GC/MS), pyrolysis compounds such as hydrocarbons, fatty acids, catechol, and catechol oxidation products were detected. This was identical to the characteristics identified upon analyzing lacquer collected from species of lacquer tree whose main component is urushiol. Therefore, it was confirmed that the stone Buddha head excavated from the Temple Site No. 4 of Yaksugok Valley was separated from a nearby stone seated Buddha statue, and that the gold foil was attached using lacquer sap collected from lacquer trees, which grow in Korea, China, and Japan.

Purpose: The purpose of this study was to identify the effects of aromatherapy on blood pressure and stress responses of clients with essential hypertension. Method: There were fifty-two subjects divided into an essential oil group, placebo group, and control group by random assignment. The application of aromatherapy was the inhalation method of blending oils with lavender, ylangylang, and bergamot once daily for 4 weeks. To evaluate the effects of aromatherapy, blood pressure and pulse were measured two times a week and serum cortisol levels, catecholamine levels, subjective stress, and state anxiety were measured before and after treatment in the three groups. Data was analyzed by repeated measures of ANOVA, one-way ANOVA, and $X^2-test$ using the SPSS 10.0 program. Results: The blood pressure, pulse, subjective stress, state anxiety, and serum cortisol levels among the three groups were significantly statistically different. The differences of catecholamine among the three groups were not significant statistically Conclusion: The results suggest that the inhalation method using essential oils can be considered an effective nursing intervention that reduces psychological stress responses and serum cortisol levels, as well as the blood pressure of clients with essential hypertension.

This study was carried to investigate the treatment characteristics of the phenol and catechol with an anaerobic fluidized bed reactor(AFBR) having a dimension of 9 cm i.d. and 1.25 m height. The reactor was operated at $35\pm 1\circ$C. The COD concentration of the effluent, the gas production rate and the composition of gas were measured to determine the performance of the AFBR as the hydraulic retention time(HRT) was decreased from 2 days to i day at 600 mg/l of the phenol and catechol concentration. Stable treatment of the phenol wastewater could be achieved with the AFBR at 18 days but the catechol wastewater couldn't be. At HRT 2 days, the phenol wastewater showed the COD reduction efficiency of 93% and the gas production of 2.7 l/day and the catechol wastewater was obtained the COD reduction efficiency of 82% and the gas production of 0.72 l/day. Also at HRT 1 day the phenol and catechol wastewater showed the COD reduction efficiency of 95% and 73% and the gas production of 4.0 l/day and 1.25 l/day, respectively.

The dying properties of fabrics with Chaenomelis Fructus extract were studied through an investigation of the characteristic of Chaenomelis Fructus colorants, the effect of dyeing conditions (dye temperature, dyeing concentration, and times on dye uptakes), effect of mordant, effect of UV irradiation, and color change in addition, antimicrobial ability and deodorant ability were estimated. In the UV-Visible spectrum, the wavelength of maximum absorption of Chaenomelis Fructus extract was 280 nm and showed that tannin is the major pigment component. From the increase of absorbance by UV irradiation, it was assumed that catechol tannin color was developed through UV irradiation. An increased dyeing concentration resulted in a larger dye uptake. Dye uptake increased as the dyeing time and temperature increased. Chaenomelis Fructus extract showed relatively good affinity to silk than cotton. Mordant, Fe and Cu were effective to increase the dye uptake of cotton fabric in addition, the dye uptake of silk fabric mordanted with Fe and K improved. UV irradiation let the color of dyed fabrics develop regardless of the UV irradiation stage however, UV irradiation on the dyed fabric was more effective than on the extract for the color development. Dyed silk fabric showed very good antimicrobial abilities of 99.9% in addition, deodorant ability improved in the fabric dyed with Chaenomelis Fructus extract.

Purpose: Anxiety and depression are the concepts that commonly used as an emotional approach in the nursing researches and most of researches have been used questionnaires as a marker of anxiety and depression. There were few researches using physiological markers in measuring anxiety and depression. Methods: Journals published between 1950 and 2007 that include depression and anxiety measuring through physiological markers were reviewed. Results: As in the case of the hypothlamus-pituitary-adrenal axis system, it appeared that cortisol, epinephrine, and norepinephrine belonged to the category of hormones which were responsive to anxiety and depression. Plasma norepinephrine was a marker of the anxiety whereas plasma cortisol was a marker of the depression. The anxiety and depression were correlated with immune and taste, but it considered as an outcome variable not a physiological marker. Conclusion: Catecholamine and cortisol reflect anxiety and depression state. Our findings suggest that further researches are needed to distinguish between markers and outcomes of depression and anxiety using physiological markers.

Fatigue is a significant problem in health care. The relationship between chronic fatigue and psychiatric disorders has generated significant interest in recent years. Increased rates of psychiatric disorder among individuals with chronic fatigue have been reported. Fatigue may be defined as physical and/or mental weariness resulting from exertion. The cause of fatigue is complex, influenced by events occurring in both the periphery and the central nervous system. Because fatigue may result from a number of causes, it should be treated comprehensively. The treatment is largely symptomatic and rehabilitative.

The vasodilatory shock after cardiopulmonary bypass is defined as the condition involving severe and persistent form of hypotension, tachycardia, normal or increased cardiac output and decreased systemic vascular resistance. Because of the unsuccessful response to infusion of fluids or catecholamine vasopressors, a sustained systemic shock state occurs and results in a high morbidity and mortality. We successfully treated this syndrome of 3 patients after open heart surgery with low dose of arginine vasopressin(AVP). Therefore, we report these cases with a review of related articles.

The present study was carried out 1) to show the ontogenic development of CA-and GnRH-containing nerve fobres in the median eminence, 2) to simultaneously demonstrate the synaptic contact between these two nenre fibres in the rat median eminence at the ultrastructural level using light and electron microscopic doublelabel immunostainlngs. GnRH-and CA-nenre terminals were detectable in the median eminence at embryonic day 19.5. The CA-newe terminals were obsenred in the entire legion of the extern31 lavers, while GnRH-newe terminals only in the lateral portion. At the 14th postnatal daw, both %ropes of nerve terminals showed a very similar distribution to those of adult one. In the median eminence of adult rats, a substantial overlap existed in the distribution of GnRH fibres with CA-containing nerve fibres. This overlap was most intense throughout the external palisade zone. Furthermore, an electron microscopic double label immunostaining showed that there was a close apposition of CA- and GnRH-nenre fobres. These axo-axonic contacts occurred frequently in the internal and palisade zones, i.e. at the level of the fobre preterminals. These morphological results suggest that the CA-mediated GnRH secretion may occur via sxo-axonic interaction in the median eminence.
