Although Quaternary marine terraces and onshore paleo-shoreline records provide clues to our understanding for the mode and nature of neotectonics in the Korean peninsula, it cannot be accomplished without knowledge on both independent information of the past sea level records and tectonic deformation field together with precise results of numerical dating for higher terraces. This study reported cosmogenic radionuclides ($^{10}Be$) dating results conducted in higher terraces in the eastern and western coasts of the Korean peninsula. As a result, the measured concentration ratio of $^9Be/^{10}Be$ and the exposure ages were much younger than expected. It implies that either there is possibility of error in experimental processes or the samples experienced a complex exposure history probably included a burial at some stage. Considering the past climatic conditions around the Korean peninsula and a possible complex exposure history after the emergence of marine terrace, the discovery of a suitable study area and a sampling site are an essential part of successful $^{10}Be$ dating technique.

Objective: In May 2011, an interview with three United States Forces Korea veterans revealed that chemicals believed to be 'Agent Orange' were buried at Camp Carroll (situated in Waegwan, Chilgok-gun, Gyeongsangbuk-do, Korea) in 1978. Many hazardous chemicals, such as perchloroethylene (PCE), trichloroethylene (TCE), and organochlorines were subsequently found in a joint US-ROK environmental investigation, although dioxins or burial evidence related to 'Agent Orange' have been not uncovered. This study was carried out to investigate the relevance of hazardous chemical exposure and health effects of the residents around Camp Carroll. Methods: The authors conducted a health questionnaire survey among residents around Camp Carroll regarding Waegwan groundwater ingestion, length of residence in Waegwan, and physician-diagnosed disease history (such as cancer, hypertension, diabetes and etc.). Logistic regression was performed to identify the associations between hazardous chemical exposure and physician-diagnosed diseases. Results: Among the 5,320 residents, excluding those living outside the Waegwan area, 3,430 subjects age 30 and over were analyzed. Among females, upon correction of age, smoking history and Camp Carroll working history, a higher distribution in the Waegwan groundwater ingestion group was demonstrated for patients with physician-diagnosed cancer and hypertension. The odds ratios have a tendency to increase with increased length of Waegwan groundwater ingestion. Conclusions: This study may be limited by not adopting a cohort study for the evaluation of factors that may confound environmental exposure. Yet it is meaningful that the correlation between Waegwan groundwater ingestion and chronic diseases were found through regression analysis in female; and further, this outcome may be used as a sampling basis for a secondary epidemiologic study.

We analyzed the preliminary survey data (2014-2016) of macrobenthic community biomass (n = 112) from the wind farm area located in the southern part of the west coast of Korea and compared this data with data from the entire west coast (n = 369; 2006-2008). Modal classes from frequency distributions were 6 times higher in the latter (5 vs. 32 g/㎡). The mean and median values of the latter were 1.3 and 1.7 times higher (mean, 20.7 vs. 27.8 g/㎡; median, 17.1 vs. 29.5 g/㎡), and the maximum value was 3.4 times higher. Mood's median test showed significant difference at p-value = 0.01. We estimated the biomass-to-depth relationships from each data set by using Akaike Information Criterion and regarded the non-overlap of the 95% confidence intervals as indicating significant difference. The biomass was different from a 10 m depth below, and 3 times higher in the west coast at around 20 m compared with the maximum depth of the wind farm area. A local event of catastrophic sedimentation ranging from 1 to 2 m was observed in the wind farm during winter surveys. This could be a probable source of the lower biomass, but information on biomass seasonality and a natural experimental approach seem to be needed for the conduct of further studies. This study is meaningful in that it provided the background to assess future changes by understanding the lower level of benthic productivity in the area. We expect this study will contribute to the preparation of measures that can remove or mitigate the source of the lower biomass and improve the productivity of fishery resources in the area.

To prepare for the changes in the future, this study considered people in their seventies and eighties in rural areas in the last decade. Based on a survey of rural life by the Rural Development Administration, all factors were analyzed using SAS ver. 9.3. The rate of rice farming decreased, and vegetable-cultivation increased from 8.4% in 2001 to and 26.6% in 2008 for people in their seventies and eighties. The number of family members decreased to 1.96 in 2010 from 2.04 in 2001, and annual income increased by KRW 20-29 million for those in their seventies and eighties, whereas it was more than KRW 30 million for those in their forties. Bathing with warm water increased to 88.9% from 69.8%, and household waste treated by self-incineration decreased from 86.4% to 40.0% in the last decade. Separate collection spread since 2008. Food waste disposal and the burial (46.0%) showed had for people in their seventies and eighties, and animal feed increased (50.7%) for those in their forties at 2001. The separate collection increased by 39.6% in 2010 for those in their seventies and eighties and by 53.5% for those in their forties(p<0.05). The manufacture of jang and kimchi showed were little annual changes for people in their seventies and eighties. Food storage processing was higher for those in their forties. For those in their seventies and eighties, food group intake over the 2004-2010 period increased from 3.3 times a week to 4.2 times a week for protein foods and from 4.9 times a week to 5.5 times a week for vegetables. There was no change in fruits, milk, and seaweeds for those in their seventies and eighties, but there was an increase for those in their forties. The results suggest the continued increase in the manufacture of jang and kimchi and protein and vegetable intake for those in their seventies and eighties. Some direction to welfare, mechanized rice planting and living with neighbors together would be continued with good nutrition for elderly residents.

A nondestructive experimental feasibility study was conducted using magnetometer to find buried cultural objects at pottery and steel matters in low-relief mountaineous area of Doojeong-dong, Cheonan, Chungnam Province from May 23 to July 18, 1998. Magnetic survey was carried out with $20cm{\times}20cm$ grid in a site of $20m{\times}40m$ before excavation, and the distribution of magnetic anomalies was compared with the results of excavation. Magnetic sensor was located on the surface of ground during the magnetic survey on the basis of an experimental result. Positive magnetic anomalies of maximum 130 nT are found over a pair of potteries. Magnetic anomaly map reveals several anomalous points in the 1st and 4th quadrants of the survey site, from where potteries and their fragments were confirmed. Six points out of seven points cprrelated with magnetic anomaly are found contain earthwares, whereas a magnetically uncorrelated location produced earthware made of unbaked clay. Steel waste such as cans and wires hidden in soil and bushes also influenced magnetic anomalies. Therefore, it is better to remove such steel wastes prior to magnetic survey if possible. Some magnetically anomalous points produced no archaeological object on excavation. This may be explained by shallower level of excavation than burial depth.

The application of magnetic method for archaeoprospection has been carried out through two archaeological areas in Egypt, Abydos and Abu Sir, In order to find out tile ancient Egyptian archaeological features. The magnetic work at the selected archaeological site of Abydos area was carried out by gradiometer survey, while magnetic work at the selected archaeological site of Abu Sir area was carried out by gradiometer survey and magnetic susceptibility measurements. A gradiometer survey with raster of 0.5 m/0.5 m has been carried out on a surface area of $9600 m^2$ at Abydos area to relocate the buried Solar Boats. The magnetic data were processed using Geoplot software to treat the field noises and enhance the quality of the obtained images. The final magnetic images indicate the existence of 12 Solar Boats as well as tombs, remains of ancient rooms and walls. All of them are expected to belong to the Middle Kingdom, particularly from the 18th to 20th Dynasties. Two magnetic tools have been applied over a selected site of $25600 m^2$ at Abu Sir area in order to detect the hidden archaeological features nearby the Sun Temple. The acquisition of the magnetic data was initiated by the measurements of the topsoil magnetic susceptibility of 272 samples collected from the whole studied area, and then followed by the gradiometer survey to measure tile vertical gradient of the geomagnetic field over an area of $14400 m^2$. The magnetic susceptibility results show the presence of high concentration at the middle part of the study area with a little extension to the south western side, with maximum value of about $36{\times}10^5$ SI. They may indicate the proximity of ritual monuments. Also, they offered the site of interest for carrying out a gradiometer survey. The gradiometer results show tile existence of numerous distributed archaeological features made of mud-bricks with different shapes and sizes. They may indicate tombs, burial rooms, dissected walls; all of them are expected to belong to the 5th Dynasty of pharaohs, who used to build their buildings by mud bricks. The depth of the expected buried archaeological features has been estimated from tihe gradiometer. It is around 1.2m for deep features and 0.42 m for shallow features.

In May 1987, 11 clay icons and other stone products were excavated in an abandoned ancient tomb which was located in 541-1 Hwangsung-dong, Kyungju. 6 clay figures of them were depicted realistically man's features and postures, costume at that time that they gave a lot of significance to the fields of Korean Costume's Academic Society. The main purpose of this thesis is to study the background of costume history when it was made and its formal characteristics with the study of those 6 clay figures. Shilla accepted the customs and attires of Sui and T'ang by means of frequent in coming and out going Chinese envoy as well as Shilla's envoy, monks, hostages, and students in China. From that period, the diversity of Shilla's costume began to develop by introducing Tang's style into Shilla's costume. Crested hat of men's clothing of the clay figures in Hwangsung- Dong is Bokdu Men's figure II wore Bokdu which Hugak is attached to Byunhyung. The garment is a Po and it is a tight sleeve and silhouette's Banryungpo. The horizontal line of hemline of men's figure 1 can be presumed by expression of Ran though it is not as accurate as the clay figues in Yongg-ang-Dong. As for torso part 1, it can not be known the style of the crested hat because the head part was damaged, but it were shoes, belt and common sleeve, Banryungpo on tight sleeve shirt and tight trouser. The hair style of the women's clothing in Hwangsung-dong clay figure is Bukkye peculiar to Korea. The costume was slim silhouette that people wore tight sleeve and short blouse and long skirt and belted on their bosom which dresses style was in vogue from late Sui dynasty to the early years of the Tang period. The silh ouette of slim silhouette's high waist which can be seen in the women's dresses is mainly worn by Chinese and affected Shilla's costume. Therefore the dresses style of the clay figures in Hwagsung-Dong, it is considered it is a dresses style of tight sleeves and slim silhouette together with the adaptation and abolition of foreign elements on the basis of Shilla's own elements like Bukkye hair style and tight sleeve and silhouette. The style of Yonggang-Dong's clay figures expresses spherical gei and common sleeve, loose silhouette of flourishing Tang's costumes planly whereas the style of Hwangsung-Dong's clay costumes expresses refined spirit of the Shilla(Shillaism) though it is extremly simple.

This study investigated the formal characteristics and chemical compositions of eighty beads excavated from a Silla tomb complex at Deokcheon-ri, Uljin in order to reveal the methods of production and the characteristics of the raw materials involved, thereby illuminating characteristics of the relics from each tomb. The beads excavated from these Silla tombs include one curved bead, one tubular bead, and 78 globular beads. Among them, the curved and tubular beads and three globular beads were identified to be made of minerals, and the remaining 75 beads are made of glass. Most of the glass beads are thought to have been produced using the drawing technique. The characteristics of the beads were classified according to their site of excavation. The globular beads from Tomb No. 34 belong to the lead-barium glass and potash glass groups, indicating that these beads were produced at a relatively earlier period in time. The glass beads excavated from the tombs in the northern portion of the complex differ in color and chemical composition from those in the southern portion, which indicates the character that each group of beads had different aspect according to site location. Considering that the excavated beads were mainly from fifth- and sixth-century tombs, it is likely that certain groups of people living around Uljin used and buried beads in their tombs. As the governance of Silla became more centralized in the sixth century, the use of beads for burial purpose appears to have come to an end in this region.

Two lime-soil mixture barrier tombs were excavated from the tomb complex of the Woo Family of the Danyang Wu clan dating to the Joseon dynasty in Godeung-dong, Seongnam-si, Gyeonggi-do. Relevant records offer information for more precisely dating these tombs and identifying their occupants. Tomb No. 4, in which a married couple was interred, has a corbeled square ceiling and inscriptions and paintings on its outer walls. The conservation treatment and an infrared inspection revealed that they were intended to express mourning. Tomb No. 6 has a corbeled rectangular ceiling and a single individual interred within. As the basic structure of the tomb was partially damaged in the process of disassembling it while moving the burial site, it was planned to exhibit the tomb outdoors after the remains and relics are collected. However, as the conservation treatment revealed the presence of funeral fans and pitch, and since the remaining structure clearly demonstrates the features of lime-soil mixture barrier tombs from the Joseon dynasty, the plan was changed following a meeting of an advisory council that decided in favor of presenting the tomb indoors. According to the analysis, the pitch is assumed to be resin of a rather low purity due to the immixture of foreign substances. The two tombs are expected to serve as important materials for related research, such as changes by period in the forms of Joseon-era tombs.
