三宜堂金氏是生活在朝鮮末期的女性詩人. 她是一個沒落士大夫的後代(金馹孫的後代), 18歲(1786)時與湛樂堂河笠締結婚姻. 她畢生留下的詩文均收錄於《三宜堂金夫人遺稿》之中, 該書於1930年出版. 三宜堂金氏十分善於寫詩, 《韓國漢詩》第3卷女性詩篇中共翻譯并收录了她的詩作59篇, 與黃真伊5篇, 蘭雪軒許氏30篇, 師任堂申氏2篇相比, 這组数字是对其實力的肯定. 甚至在趙東一编纂的《韓國文化通史》卷3中也提及到了三宜堂金氏, 可以說她是一位非常優秀的詩人. 三宜堂金氏作為士大夫閭閻家的詩人, 主要創作詩歌, 所創作的詩文中有不少關於#x300A;詩經》的內容. 她熟讀《詩經》并確立了《詩經》觀及詩觀, 很好地掌握并发挥《詩經》詩的效用性及活用性, 这为她自己詩歌性質和特色的形成, 奠定了基礎. 三宜堂金氏在自己創作的235篇詩中, 活用《詩經》詩句, 展示各種表現手法, 这是非常出色, 达到了其他诗人無法模仿的水平. 她使用的手法有以下几种:引用《詩經》詩語, 對《詩經》詩句進行再調和及化用, 《詩經》詩句的再造合及化用. 其中最高超的表現手法可以說是《詩經》詩句的再造合及化用. 金夫人在創作詩作時, 既有原封不動地引用《詩經》詩語或詩句的情況, 但大部分使用了《詩經》詩句再造合及利用的這種手法, 既類似於《詩經》詩句, 卻換作其它表現來表達自己的想法, 十分巧妙靈活. 這種活用不同與自春秋時代開始流行的《詩經》詩篇的"斷章取義". 金夫人將這種手法運用到自己的詩篇中, 既作爲詩的表現根據, 同時使詩具有含蓄性, 在營造詩歌古樸風格時, 呈現出高水平的境界.

The research investigated the interaction effect of video resolution and device luminance on the perceived characteristics, presence, and fatigue viewing virtual reality. Experiments were composed of mixed design, and the resolution and luminance were classified into three types, HD, 2K, and 4K, and 20, 60, and 100, respectively. Participants watched video of 6-minutes randomly, and responded to the questionnaire after watching each video. The results showed that no interaction effect existed. Meanwhile, there are statistically significant differences on the luminance of depth perception, the resolution of visual intervention, and the resolution of adjustment fatigue. Also, higher resolution and luminance showed higher cognitive function, presence and fatigue.

By means of the compatibility according to solving environmental pollution and energy problem due to the emissions of NOx and smoke from diesel engine this paper experimentally inspected the effect of using emulsified fuel, gas oil-water, for combustion characteristic, that is combustion pressure, pressure rise rate, heat generating rate, the period of ignition delay and specific fuel consumption, and CO, HC, NOx concentration and smoke density. When using emulsified fuel, as a water addition rate was increased, combustion pressure, pressure rise rate and heat generating rate was increased, the period of ignition delay was lengthening, the specific fuel consumption was some what increased in contrast to diesel fuel in low load, but deceased in high load region. And NOx concentration was decreased, CO concentration was increased in low load, but decreased in high load region, HC concentration was increased in contrast to diesel fuel in all region.

Eddy covariance method is widely used in measuring vertical fluxes of mass and energy between the atmosphere and the biosphere. In this method, scalar concentration is measured with either open-path or closed-path sensors. For the latter, fluctuations of scalar concentration are attenuated as the sample travels through a long tube, resulting in flux loss. To quantify this tube attenuation, water vapor concentrations measured with both closed-path and open-path sensors were analyzed. Our statistical analysis showed that the power spectral density obtained from the closed-path sensor was different from that from the open-path sensor in the frequency range of > 0.5 Hz. The loss of water vapor flux due to tube attenuation was < 5% during midday. At nighttime, however, the flux loss increased significantly because of the low wind speeds and the weak turbulence sources. Theoretical calculation for the tube attenuation showed a small bias in high frequency range probably because of the interaction of sticky water vapor with a tube wall.

Under the background of regional cultural development and cities' diversity, various tourist destinations attract tourists' attention and visit by mining their unique folk culture. As a part of sustainable tourism, gastronomy tourism can provide residents and tourists services only by improving the residents' facilities without damaging the environment. However, the existing gastronomy tourism only makes tourists in the folk scene, and tourists can not overstep the cultural differences caused by intersubjectivity to experience the core of folk culture. This paper attempts to use the observation method, cross-subject study, and case study to study the role of food docent-guided tours in understanding folk culture. Moreover, the docent-guided tour studies how the docent can help tourists go deep into the core of folk culture better to realize the sustainable development goal of gastronomy tourism.

This study investigates the delay in setting characteristics of mortar influenced by variations in super retarding agent(SRA) content, curing temperature, and strength levels. Utilizing a settimeter, the research introduces an objective approach to accurately determine the setting time of concrete with SRA under diverse environmental and material mixing conditions at construction sites. The findings indicate that the settimeter, in conjunction with a nonlinear regression model, can effectively estimate the setting time of super retarding mortar. Optimal management of the initial setting is recommended at approximately 45ST and the final setting around 80ST. This methodology enables more effective quality control in the setting times of super retarding concrete.

Most of total nitrogen in the surface soil exists in organic forms, of which amino acid-N is the major fraction. By-product fertilizers provide soil with humic substances, and humic acid is an essential component of humus. Amino acids(AAs) are easily converted to inorganic-N forms and thus play an important role in N fertility. This experiment was conducted to investigate the contents and distributions of AAs in humic acids which were extracted from the commercial by-product fertilizers of different composting materials. Total contents of AAs in humic acids ranged from 1.2 to 5.6%, of which neutral AAs were the highest with ranges of 0.8~4.5%. AAs contents in fertilizers composted from the plant residues such as leaf litter, sawdust and bark were in an order of neutral>acidic>basic AAs. In contrast, those from animal wastes, such as poultry and pig manures, were in an order of neutral>basic>acidic AAs. Distributions of total, acidic and neutral AAs were in the respective order of leaf litter>sawdust>pig manure>poultry manure>peat, bark>sawdust>leaf litter>peat and leaf litter>sawdust>bark>peat. Distributions of the basic AAs were in the reversed order of the acidic AAs. In bark fertilizer with increasing compost maturity, contents of the acidic AAs were increased in compensation for the decreases in those of neutral and basic AAs. Results demonstrated that distributions of amino acids in humic acid of by-product fertilizers were different from composting raw materials and degrees of humification.

A new devised conductivity meter was used in the rapid and convenient determination of salt contents of soysauce and margarine. The equation $(1){\sim}(5)$ was set up between the electric conductivity (x) for 100 times diluted solution of soysauce and the salt contents (y). y=0.083x-1.253 $(at\;15^{\circ}C)$ (1) y=0.077x-2.062 $(at\;20^{\circ}C)$ (2) y=0.071x-2.686 $(at\;25^{\circ}C)$ (3) y=0.066x-3.153 $(at\;30^{\circ}C)$ (4) y=0.062x-3.522 $(at\;35^{\circ}C)$ (5) y=(-0.001139t+0.0999)x+(-0.126t+0.557) $(temperature\;range;\;15{\sim}35^{\circ}C)$ (6) y=salt contents [%], x=conductivity $[{\mu}{\Omega}^{-1}{\cdot}cm^{-1}]$, $t=temp.\;[^{\circ}C]$. The salt contents could be estimated by the equation $(1){\sim}(6)$ and the measured conductivity. The estimated salt contents agreed with that determined by conventional method within 0.27[%] as salt contents. For margarine, the equation (7) was setup between the conductivity (x) and the salt contents (y) y=0.00266x+0.057 $(at\;20^{\circ}C)$ (7) y=salt contents [%], x=conductivity $[{\mu}{\Omega}^{-1}{\cdot}cm^{-1}]$ The salt contents estimated with the equation (7) and the measured condutivity agreed with that determined by conventional method within 0.028[%] as salt contents. The electric conductivity obtained with conductivity meter could be a valuable criteria salt contents test of Korean soysauce and margarine determining in a few second or minute by handy compact portable meter.
