The ozone concentrations measured at the National Air Monitoring Stations between 1990 and 1995 were reviewed to detect any anomalies in the measurements. By screening the cases, in which variation of the ozone concentration from the previous measured value is greater than 75ppb, 125 station-days were identified as the test cases for the anomaly test. Historical and parallel consistencies of the measured concentrations were examined by plotting data for each test case. The detected anomalies can be classified into four categories; single outliers, anomalous variations during the startup period, baseline rises, and fluctuations in th diurnal variations. Anomalies were detected in as many as 80 cases among 125 test cases. Because of these anomalies, the number of hours exceeding 100ppb in the areas other than the Greater Seoul Area(GSA) could decrease from 157 to 107. Further studies for developing the methodology for eliminating the abnormal monitoring data are warranted for the data from the National Air Monitoring Stations are official to the both inside and outside of the country.

This study investigated the changes that occurred in housework from the traditional socie쇼 focused on the Yi Dynasty to the industrial society in Korea using the methods of historical research. The changes that occurred in housework had two principal effects. The first was to integrate the work of servants and children to the work of women. In the Yi Dynasty the servants called Nobi were entrusted with the hard housework and the children from their earliest dys assisted women in the house. The second was markedly to increase the productivity of the average housewife. In the period of industrialization the household technology might have eliminated the labor of housewives but housewives took the responsibility of almost all the processes in housework.

"Jung Ri Eui Kwae" is the book, illustrated and recorded with court coutesy and manners during the King, Jung Jo's honoured coming to his own father's royal tomb "Hyun Ryung Won" of Sa Do Seh Ja(The Crown Prince to be mourned) with his own mother Hae Kyung Koong Mrs. Hong. According to this book, we can see the costumes and its ornaments of the civil and military officials and also of Yu Ryung(the maden court musician) and Dong Ki (a young Kisaeng girl) during serving at Bong Soo Dang bangquet celebrating his own mother's 60th birthday anniversary. It is interesting to review once more the royal ceremonies representing the portion of the costumes and its ornaments in the 18th century of the Yi Dynasty, Yung-Jung Jo era that is to be thought the reform period in almost every field of social system.

The purpose of this paper is to review the contribution made by some phoneticians including Si-gyung Chu, Du-bong Kim, Hyun-bae Choi, and Geuk-ro Lee in the early 20th century. It is known that the period can be characterized as the coexistence of traditional phonetics and modem phonetics. Si-gyung Chu well recognized the physical nature of speech sounds from the physiological point of view. Although Du-bong Kim adapted Chu's approach in some ways, he made some more detailed modifications in explaining the vocal organs. Hyun-bae Choi tried to explain the consonants and vowels systematically based on Western theories of phonetics. Finally, Geuk-ro Lee made the most significant contribution by introducing the experimental phonetics.

Osteochondral lesions of the talus are isolated cartilage and/or bone lesions that are known cause of chronic ankle pain. They can occur as the result of a single acute ankle injury or from repetitive loading of the talus. Technical development in radiologic imaging and ankle arthroscopy have improved diagnostic capabilities for detecting osteochondral lesions. Characteristics which are important in assessing an osteochondral lesions include: the size, the type (chondral, subchondral, cystic), the stability, the displacement, the location, and the containment of lesion. Nonoperative treatment involving period of casting and non-weight-bearing is recommended for acute, non-displaced osteochondral lesions in select pediatric and adolescent patients. Operative treatment is recommended for unstable lesions or failed conservative management. Marrow stimulation techniques (abrasion chondroplasty, multiple drilling, microfracture), osteochondral autograft or allograft, autologous chondrocyte implantation, are frequently employed. The purpose of this article is to review the historical background, etiology, classification systems, diagnostic strategies, and to describe a systematic approach to management of osteochondral lesions of the talus.

The purpose of this study is to understand the meaning of architectural history of designated cultural properties of modern educational facilities through the analysis of its status. This study considerate acceptance and evolution of modern educational facilities during the about seventy years from 1895 to 1965. Also, this study analyzes items that is distribution of construction and designation year, regional groups, and status of main structure material, status of conservation and utilization of facilities, its characteristics of architectural style. In this study, the result of analysis show that most analysis items of investment buildings are tend to biased and concentration to one direction. Accordingly, designated cultural properties of modern educational facilities are weakly express architectural representation and symbolism in the period of modern educational acceptance.

Simyak (審藥) was a government officer to lowest, but it was appointed and dispatched directly by officials from the central government. Simyak played a role in mediating between the provincial and central health care. Therefore, understanding Simyak is necessarily required in the researches on the local health care in Joseon dynasty. Preceding researches of Simyak only have contained superficial information causing many errors. The purpose of this paper is to understand Simyak correctly through the historical literature review. The author found the following facts in this study. First, Simyak was succeeded to the government officer of Uihakgyoyou (醫學敎諭) in the previous period. Second, through the change of the name of Simyak, it can be presumed that the main task of Simyak was changed from the role in local medical education to the officer sending the herbs to the central government. Third, in the later Joseon dynasty Simyak was monopolized by some families just like any other medical officials. Fourth, Yangdowollyengui (兩都月令醫) and Tongyeongguryogwan (統營救療官) can also be put in the category of Simyak.

One of the hazard of nature is a drought. Its impact varies from region to region and it is difficult for people to understand and define due to differences in hydrometeorological and social economic aspects across much of the country. In the most general sense, drought originates from a deficiency of precipitation over an extended period of time, usually month, season or more, resulting in a water shortage for some activity, group, or environmental sector. Palmer Drought Severity Index (PDSI) is well known and has been used to study aridity changes in modern and past climates. The PDSI index is estimated over US using USHCN historical data.(e.g. precipitation, temperature, latitude and soil moisture). In this study, low frequency drought variability associated with climate variability such as El-Nino and ENSO is mainly investigated. With respect to the multi-scale analysis, wavelet transform analysis is applied to the PDSI index in order to extract the low frequency band corresponding to 2-8 years. Finally, low frequency patterns associated with drought by comparing global wavelet power, with significance test are explored.

This research examines the concept of 'homo sovieticus' by reviewing the sociological essay novel homo sovieticus written by Zinoviev who was one of the well-known dissident in Soviet Union period, and attempts to have critical understanding of the concept. It is an interesting research topic that current Russia and Russians who get through the historical layers from Soviet to post-Soviet regime at the time current trend that allows to have various academic discussions of post-Soviet. It is required to examine the past of Russia and Russian to make precise estimation of their current and future. Therefore, it is necessary to re-examine the term of 'homo sovieticus' which is conventionally accepted. This research aims at broad comprehension of homo-sovieticus by focusing on the Zinoviev's own understanding instead of the habitual use of the term which only contains ideological and political intention.

Obelisks are historical monuments. There are several obelisks dating from ancient Egyptian period, located around various parts of the world. The city of Istanbul is a home to the Obelisk of Theodosius at the Hippodrome. Due to the expectation of a large event in the near future, the evaluation of seismic response of the Obelisk gets importance. Therefore, in this study structural dynamic behavior of the Obelisk was investigated using discrete element approach. Nonlinear dynamic analyses were performed using real and synthetic time series. Real and synthetic ground motions analyzed from this study seems consistent with the earthquake hazard levels that would be expected at the site of the Obelisk in the occurrence of an event of moment magnitude above 7.0 near Istanbul. Results are evaluated in terms of variation of displacement, relative displacement of adjacent blocks, normal stress and shear stress in time.
