Since the suggestions on the paleo-glacial landforms in and around the northern high mountains of Korean Peninsula by some western and Japanese scientists in the early 1900s, the likelihood of the glacier existence in the Baekdusan over the Quaternary glacial period has been had in common among most of the Korean geomorphologists. In the other meaning, some have cast doubt on the likelihood the paleo-glacier in the Baekdusan because there has been no unequivocal evidences for the glacier such as striation, moraines, except morphologic characteristic landforms possibly related to glacier. Here we show some evidences for the existence of the glacier in the Baekdusan and their cosmogenic $^{36}Cl$ exposure ages over the late Quaternary and would put forward a model on the Quaternary landscape evolution of the Baekdusan, with a focus on the relationship of 1000 AD explosive eruption and the glacial landforms. The exposure ages constrained by cosmogenic $^{36}Cl$ abundances of the col surface of the western slope located below the glacier yield 46~26 ka, which is inphase with the last glacial period. Given all the evidences above, we can draw a conclusion that the glacier existed on the Baekdusan over the late Quaternary and the style of glaciation changed from extensive ice cap through valley glacier to restricted cirque.

Field observations have been conducted to investigate the physical environment around oyster farms in Gamak Bay. Tidal waves near the two channels at the northeast and south of the bay had almost the same amplitudes and phases. Water temperature responded sensibly to the tides, rising at high water and falling at low water, except for the northwest region. The currents more regularly varied in accordance with a tidal period as long as they are at the faster-flowing region. A considerable flow has been found near the seabed of the northwest of the bay, normally known to be a stagnant area, and also the flow was opposite to the surface flow. Average moving speeds and directions of the flow at each station coincided well with patterns of the residual currents computed by Lee ef al. [2004], except for the northwest region. The discrepancy for the northwest region is not clear but it may have resulted from the facts that the computed flow pattern represents only the case of spring tide and in addition, a northwesterly wind prevailed all the observation time.

The three generations of Haenam Yoon, who have been handed down to Gongjae Yoon DuSeo (1668~1715), Yoon DeokHee (1685~1776) and Yoon Yong (1708~1740), were based in Haenam. They had an artistic soul on the stage of Hanyang and succeeded in the art of the family, building a reputation as a family of Seonbi painters representing the late Joseon Dynasty. Born as the eldest son of Gongjae and lived at the age of 82, Rakseo learned a variety of studies, calligraphy and painting from his father and Lee Seo. While learning the paintings of the early and mid Joseon period, and accepting the Namjong painting method, he pursued the realism and three-dimensional sense of the subject by adding a Western-style shading method. In particular, he showed outstanding talent in horse paintings and pottery figures, expressing his original 'Beauty that realistically portrays real scenery'. Cheonggo, who was born as the second son of Rakseo and died at the age of 32, was good at Namjong landscape painting using various tree drawing methods. He painted the original Siuido by changing the topical poems, as well as detailed observations and explorations to accurately describe the facts of the object. In addition, 'Beauty showing affection through realistic scenery' was expressed by newly changing and reinterpreting the tendency of home appliances painting to express the spirit as a form beyond the realistic landscape. Rakseo and Cheonggo father and son made a 'NogUdang' painting style, drastically changing the paintings of the late Joseon Dynasty, and had a great influence on the history of Korean painting.

The purpose of this study was to investigate the kinds of native and prohibitive foods in Hansan-Do area. The kinds of the prohibitive foods and the reason prohibiting those from pregnant or lactating woman, fisherman and sick people were surveyed by using a guestionnaire from 1994 to 1998. The results showed that Chungmu Gimbab was perceived highly as a native foods and the reason for prohibiting specific foods was not based on scientific evidences.

This paper reviews the results of recent observations in the Yeonsuri valley of Mt. Youngmun during springtime (March to May) in 2012. Automated weather stations were installed at twelve sites in the valley to measure temperature and 2, 3 dimensional wind. We examined temporal and spatial characteristics of temperatures and wind data. The Yeonsuri valley springtime average temperature lapse rate between the top and bottom of the entire period is $-0.44^{\circ}C/100$ m. It can be changed by the synoptic weather conditions, the lapse rates is greatest in order of clear days ($-0.48^{\circ}C/100$ m), rainy ($-0.41^{\circ}C/100$ m) and cloudy days ($-0.40^{\circ}C/100$ m). In the night, the temperature inversion layer (thermal belt) and the cold pool are formed within the valley. In addition, we measured temperature and wind distribution from the bottom to 3.5 m, the cold layers existed up to 1.5 m, which were affected by ground mixed layer. The results will provide useful guidance on agricultural practices as well as model simulations.
