This paper analyzed how people of Late Chosun Dynasty communicated through the 8 Korean novels with the assumption that the fictitious world of novels reflect the social circumstances of that time. In oral communication, hierarchical relationship of kin was the most important variable. Between strangers social status was the most important variable. The communication between people and the authorities was performed mostly by oral because the majority of people were illiterate. In village community, information on the common interest diffused by oral communication in bank of stream, parish pump and auberges. Through this process the public opinion of community was formed. In media communication diverse patterns were performed, such as letters, written materials, and diary. Contrary to the western culture, it was analyzed that written material was taken more reliable than oral communication. The fact that reading diaries of others were permitted showed that the concept of privacy had not existed yet. Books were used for the purposes of education and leisure. In conclusion it can be said that the communication of people in Late Chosun Dynasty was mainly by oral communication and supplemented by written materials.

In this study, how to instruct the computational estimation of addition and subtraction was considered from the perspective of a 'intended-written-implemented' multi-dimensional curriculum. To this end, the 2015 revised elementary school mathematics curriculum as a intended curriculum and the 2015 revised first~sixth grade textbook as a written curriculum were analyzed with respect to how to instruct the computational estimation of addition and subtraction. As an implemented curriculum, a research study was conducted in relation to the method of instructing teachers about the computational estimation of addition and subtraction. As a result, first, it is necessary to discuss how to develop the ability to estimate and set it as a teaching goal and achievement standard in a separate curriculum to instruct it with learning content. Second, it is necessary to provide an opportunity to learn about various estimation methods by presenting specific activities so that students can learn the estimation itself in a separate operation method. Third, in order to improve the computational estimating ability of addition and subtraction, contents related to the computational estimation need to be included in the achievement criteria, and discussions on the expansion of the areas, and the diversification of the instructing time will be needed.

1. Objects This paper was written in order to understand the formative process of Soyangin pharmacology. 2. Methods We analysis Soyangin pharmacology through pathology and new prescription in ${\ulcorner}$Gabobon(甲午本)${\lrcorner}$ and ${\ulcorner}$Sinchukbon(辛丑本)${\lrcorner}$ of ${\ulcorner}$Dongyi Suse Bowon${\lrcorner}$. 3. Results and Conclusions New prescription of Soyangin in ${\ulcorner}$Gabobon${\lrcorner}$ is same or similar to that in ${\ulcorner}$Chobonkwon${\lrcorner}$. So we can recognize that almost Soyangin pharmacology of ${\ulcorner}$Gabobon${\lrcorner}$ is made when Dongmu write ${\ulcorner}$Chobonkwon${\lrcorner}$. And the maintenance of Yin-Qi is key point of Soyangin's pharmacology New prescription of Soyangin is made by regular rules in ${\ulcorner}$Sinchukbon${\lrcorner}$. Dongmu say that Hyungkae(荊芥) Bangpung(防風) Kanghwal(羌活) Dokhwal(獨活) is herbs for descending-Yin, and Sukjihwang(熟地黃) Sansuyoo(山茱萸) Bokryung Taeksa(澤瀉) or Saengjihwang(生池黃) Sukgo(石膏) Jimo(知母) is herbs for ascending-Yang And all new prescription except Sukjihwangkosam-tang(熟地黃苦蔘湯) is composed of asneding-Yang and descending-Yin's herbs. New prescription of the exterior disease contained all descending-Yin's herbs and that of the interior disease contained all ascending-Yang's herbs completly. Namely when ${\ulcorner}$Gabobon${\lrcorner}$ was written Soyangin pharmacology is the maintenance of Yin-Qi by selecting prescription of cold character. And when ${\ulcorner}$Sinchukbon${\lrcorner}$ was written, base sprit of Soyangin pharmacology was not changed. Pharmacology was added ascending-Yang and descending-Yin at a time.

The first record of buckwheat in Korea was revealed from an old Korean book, "Hyangyakguguebbang(鄕藥救急方)" written in the era of king 'Gojong' who governed the country from AD 1236 to 1251 in the Korea dynasty. Buckwheat in Korea has been known to be introduced from China in 5th -6th century. One of the most famous buckwheat noodles, 'Naengmyeon' had been used popularly among the people in the Korea dynasty. It is true that buckwheat had been cooked and sold in temples during the Korea dynasty, and was regarded it as one of the temple foods at that time. Buckwheat has been cultivated as an alternative crop and buckwheat grains have been used as a hardy plant when the food situation for people was lacking in Korea. Buckwheat was an important crop in a slash-and-burn field(shifting cultivation) of the mountainous area in Kangwon province. A written history of the shifting cultivation in Korea was found in an old book "Taekriji" which was written by Lee, Jung-Hwan in the Chosun dynasty. The area and number of households of shifting cultivation in Korea was 40,000 ha and 135,000 household, respectively in 1973. Fifty to sixty kilogram of buckwheat grains per la was harvested at an altitude of 600 - 800m. Folk songs which have been sung among the people in shifting areas include buckwheat meal. One of the folk songs for buckwheat is as follows; "they do not eat rice with or without waxy property but eat buckwheat mixture." Since 1974, shifting cultivation has been legally prohibited to allow revegetation of destroyed mountains and rehabilitation of woodlands in Korea. Buckwheat has been traditionally marketed as noodle or flour for the manufacture of noodles, and also as groats for food in Korea. Consumption in markets has increased over the past several years. Buckwheat grains are mainly consumed in the form of noodles in Korea. However, many people have recently pursued a desire to make food products of high quality in processing buckwheat materials for health reasons.

Currently, the existing schedule management of ship repair has depended on hand-written notes of engineering manager in the repair ship yard. Simple management based on the hand-written notes is inefficient because current states of equipments and staff are not graspable in real-time. To solve this problem, the ICT based scheduling method is required in ship repair industry. In this paper, we propose a system based on ICT which manages schedules for repairing ships. The proposed system solves the problem occurred by the management to use the hand-written notes. Because the system has a function to report the current state of ship repair, it is able to cope with various problems, such as delay, wrong repair and so on. Moreover, the system is able to maximize the efficiency of ship repair process due to efficient management to staff and equipment.

Objectives : In this paper, the outline and overall content of the Majinhwiseong, a specialized medical text on measles written by Lee Wonpung was introduced, along with its academic historical meaning. Methods : The entire Majinhwiseong was analyzed according to content and form. In terms of form, organization, construction, cited literature, etc., were studied, while in terms of content, diagnosis of disease pattern and treatment formulas were studied. Later, based on cited medical texts and the author's social position, the academic historical meaning of this book was discussed. Results : Through the Majinhwiseong, Lee Wonpung strengthened the credibility of the text by not only providing medical knowledge on measles but listing their sources and comparing and analyzing related contents. In the diagnosis part, Lee focused on the changes in symptom, shape, color, and pulse of measles, discussing in detail its differential diagnostic methods. In the treatment part, while listing numerous formulas suggested by Ming (明) masters, Lee did not leave out treatment experiences of Joseon physicians. Meanwhile, the Majinhwiseong is indicative of measles medicine in 18th century Joseon having been progressed in the private sector rather than the official, and how the results of private sector medicine were being absorbed into the official realm through the Uiyakdongcham (議藥同參) system. Conclusions : The Majinhwiseong is a practical treatment manual written by clinician Lee Wonpung to deal measles which was widely spread at the time. The author organized existing medical knowledge on measles for clinicians while reflecting outcomes and medical situation of Joseon physicians in this book. Based on these findings, we could verify that medicine in 18th century Joseon had been progressing actively around the private medical sector.

In this article, the problem of a two-dimensional thermoelastic half-space are studied using mathematical methods under the purview of the generalized thermoelastic theory with one relaxation time is studied. The surface of the half-space is taken to be thermally insulated and traction free. Accordingly, the variations of physical quantities due to by laser pulse given by the heat input. The nonhomogeneous governing equations have been written in the form of a vector-matrix differential equation, which is then solved by the eigenvalue approach. The analytical solutions are obtained for the temperature, the components of displacement and stresses. The resulting quantities are depicted graphically for different values of thermal relaxation time. The result provides a motivation to investigate the effect of the thermal relaxation time on the physical quantities.

Let $P_c(z)=z^n+c$ be a complex polynomial with an integer $n{\geq}2$. We derive a criterion that the critical orbit of $P_c$ escapes to infinity and investigate its applications to the degree-n bifurcation set. The intersection of the degree-n bifurcation set with the real line as well as with a typical symmetric axis is explicitly written as a function of n. A well-defined escape-time algorithm is also included for the improved construction of the degree-n bifurcation set.
