Annals of the Joseon Dynasty is the authentic record of the historical facts and events taken place throughout the entire period of 472 years(25 generations, 1392~1863)described in a chronological order. The tremendous volume of the records contains the factual events taken place in almost all the fields of the Joseon Dynasty ranging from politics, economy to history of the dynasty. Not only because of its affluent contents but also with the precision of its records, it was designated as the National Treasure No. 151 in1973 by the Korean government and also registered as the Memory of the World by UNESCO in October 1997.This study is to report a exhaustive investigation results on the conservation state of annals of the Joseon Dynasty, especially Mt. Jeongjoksan edition, under the storage of the Kyujanggak in order to obtain the current condition, and thereby to estimate the any deterioration of the waxed volumes in the future. According to results of the investigation, we are going to verify damage causes of annals of the Joseon Dynasty, and to consider scientific conservation methods for the permanent preservation of invaluable cultural heritage. The major problem with the preservation of annals has arisen particularly from the deterioration of the waxed volumes of the Mt. Jeongjoksan edition. In order to provide for the counter measures for this problem, we have conducted twice investigations(first :1998~1999, second : 2003) to the internal and external conditions of waxed volumes(Annals of King Taejo~Annals of King Myeongjong).The result of the investigation has indicated that the paper quality of the some of the waxed volumes (Annals of King Taejong~Annals of King Sejong) is cracked and folded and the pages are imbedded to each other due to the hardened or congealed wax on the paper. Some of the pages are even getting moldy. And in order to detect as to whether“ there has been any deterioration progressed to the waxed books in the modern storage facility of the Kyujanggak equipped with constant temperature and humidity condition, the first investigation(1998~1999) and the second investigation(2003) have recorded the values of acidity, whiteness and moisture rate of the waxed paper, reporting an observation that there has been no difference on the measuring items. This indicates that no virtual deterioration has been progressed so far to the waxed volumes preserved in the Kyujanggak. Also, except for the causes of deterioration to the paper by insects and microorganisms, the major cause for the paper damage seems to the change of moisture of the paper caused from the alteration of the temperature and humidity of the storage environment. With this understanding in mind, we have conducted an environmental investigation on the three selected points of the storage in the aspects of the temperature, humidity, air current, $CO_2$,HCHO, and $SO_2$.It has been observed that the temperature stood at $16.9^{\circ}C~20.2^{\circ}C$ and the humidity was stable between 53%~56% during the period of the investigation. The concentration of the carbon monoxide and carbon dioxide of the storage were very similar to those in the air. These data lead to presume that there is no problem in the aspect of carbon oxidization. But the concentration of sulfur dioxide, hydrogen sulfide and formaldehyde of the storage were detected a little higher than those of standard. Therefore, we consider that it is necessary to ventilate the internal air of the store room by means of operating air purification devices.

There are several methods of pest control for the prevention of wooden cultural properties from damages caused by insects, especially termites. Those are as follows; physical control, chemical control, biological control, and integrated pest management. In Korea, we primarily use mvestigation of monitoring, fumigation, treatment of insecticidal and antiseptic chemicals, soil termiticide treatment, and termite colony elimination system. As damages by termites were detected at Eunghyanggak and Saundang of Haeinsa temple in June, 1998, we carried out monitoring with wooden device, in order to investigate damages of wooden building by termite and paths of termite invasion. According to the result of investigation of monitoring from1999 to 2002, we found that termites were inhabiting continually at forests around Haeinsa and that wooden buildings such as Saundang, Cheonghwadang were damaged by termites. So we thought that control methods such as soil termiticide treatment and termite colony elimination system would be effective. Especially, to investigate efficacy of termite colony elimination system, we carried out efficacy test of termite colony elimination system in Jongmyo during 17 months(2000.7.~2001.11.). The result of efficacy test showed that termite colony elimination system eliminated termite colonies gradually(over 12 months from installation of colony elimination system to elimination of termite colony).

N/A Postherpetic neuralgia is frequently painful, incapacitating, mood depressing, and sometimes lifelong. We investigated the influence of duration from eruption to nerve blocks in conjunc- tion with patients age on analgesic and preventive effect for postherpetic neuralgia. We retrospectively evaluated 50 outpatient medical records for the above T4 dermatome. Patients had been referred to pain clinic and were treated over 2weeks from Jan. 1988 to Dec. 1993. Fifty patients were divided into 4 groups as follows: Group I (a) less than 4weeks from eruption to nerve block and younger than 65 years old. Group I (b): less than 4weeks from eruption to nerve block and older than 65 years old. Group II (a): more than 4weeks from eruption to nerve block and younger than 65 years old. Group II(b) more than 4weeks from eruption to nerve block and older than 65 years old. Mean number of stellate ganglion blocks were 29.7. Tramadol, amitriptyline, nicardipine were most commonly prescribed. Group I (a) had the most improvement rate(77.8%) as com- pared with other group(46.6, 52.7, 56.0%). Number of patients who complained of severe pain (VAS>5) were 0, 3(39%), 2(15.4%), 5(30%) in I (a), I (b), II (a), II (b) group respectively. In conclusion, analgesic effect was best in cases of patients younger than 65 years old whose treatment were started within 4 weeks of eruption. Patients older than 65 yrs, analgesic effect did not vary on the timing of treatment.

포스파티딜세린(Phosphatidylserine; PS)은 생체막에서 구조적인 역할을 담당하는 인지질로서, 생체 내 다양한 세포작용에 필수적인 신호전달 효소의 보조인자로서 작용하는 것으로 알려져 있다. 하지만, PS의 생리활성에 대한 연구는 거의 이루어지지 않았고, 특히 피부에서의 생리활성에 대한 연구는 전무한 실정이다. 본 연구에서는 무모생쥐의 피부에 tape-stripping으로 경표피수분손실(TEWL)의 증가를 유도한 후, PS를 도포함으로써 그 손실을 현저히 감소시켰다. 또한, PS 도포군의 피부에서 세라마이드 함량이 증가된 사실을 확인한 바 있다. PS 도포군에서 non-hydroxyl 세라마이드와 glucosyl 세라마이드의 함량이 비처리군과 비교하여 각각 1.4배와 1.6배로 증가하였다. PS는 또한 피부각질세포의 분화를 촉진하였다. 피부각질세포에 PS를 처리함으로써 세포 형태가 분화상을 띄고 있음을 현미경 상에서 확인하였고, 표피분화의 특이적 표지 단백질인 Involucrin (INV)과 Transglutaminase 1 (TG'ase 1)의 발현이 각각 3.5배와 3배로 현저히 증가하였음을 웨스턴 블랏을 통하여 확인하였다. 또한 무모생쥐 피부에 PS를 도포한 결과 INV와 loricrin 단백질 발현이 증가하였다. 본 연구는 PS가 피부에서 생리활성을 나타낸다는 최초의 증거를 제시하며, 구체적으로는 각질세포 분화를 촉진함으로써 피부 세라마이드 함량을 증가시키고 경표피 수분손실을 감소시켜 궁극적으로 피부장벽을 강화하는 작용을 한다는 것을 보여준다. Phosphatidyiserine (PS) is a phospholipid which plays the structural role in membranes and serves as a cofactor of signaling enzymes for diverse cellular functions. In this study, we observed that topical treatment with PS significantly decreased trans-epidermal water loss (TEWL) induced by tape-stripping in hairless mice. Also, ceramides in epidermis were increased in PS-treated group compared to vehicle-treated one in vivo. the amounts of non-hydroxyl ceramide (NHCER) (1.4 fold) and glucosylceramide (glucosylCER) (1.6 fold), in the skin of hairless mice, were increased by topical treament with PS. Also, we demonstrated that PS stimulated keratinocyte differentiation. We observed that PS treatment morphologically altered normal human keratinocyte (NHK) from the proliferating phase to the differentiating one, suggesting that PS stimulated epidermal differentiation in NHK. We also showed that the expressions of the specific markers for epidermal differentiation, involucrin (INV) (3.5 fold up) and transglutaminase 1 (TG'ase 1) (3 fold up), were significantly increased by PS treatment, compared to untreated control in vitro. In addition, topical treatment with PS resulted in a progressive increase in INV and loricrin protein levels in vivo. In conclusion, we provide the first evidence for the physiological activities of PS in skin, and we suggest that PS strengthen the epidermal permeability harrier by stimulation of keratinocyte differentiation.

국내에서 생산된 채소류 15종 620건에 대해 수은 함량은 Mercury analyzer로, 납, 카드뮴, 비소, 구리, 망간, 아연 등은 습식분해 후 ICP로 분석하였다. 본 연구 결과, 채소중 미량금속 함량(최소~최대(평균), mg/kg)은 수은 0.0001~0.019 (0.002), 납 0.001~0.28(0.02), 카드뮴 0.001~0.078(0.016), 비소 0.001~0.06(0.02), 구리 0.06~24.81(0.77), 망간 0.17~15.12 (2.32), 아연 0.13~28.70(2.51)으로 나타났다. 본 연구에서 얻어진 분석치들은 국내외 다른 연구자들의 분석치와 비슷한 것으로 나타났으며, 이는 우리나라에서 생산된 채소류중의 미량 금속 함유량은 오염된 수준이 아닌 자연 함유량 수준인것으로 파악되었으며, 우리나라 사람이 이들 농산물로부터 섭취하는 미량금속의 양은 안전한 것으로 판단된다. 또한 우리나라 국민이 채소류를 통해 섭취하는 납, 수은, 카드뮴 등의 중금속 주간섭취량은 FAO/WHO에서 중금속 안전성 평가를 위해 정한 PTWI의 2~7%를 차지하고 있다 This study was conducted to estimate the contents of trace metals in vegetables which were produced in Korea. The levels of trace metals were determined using a mercury analyzer, an ICP (inductively coupled plasma spectrometer) and an AAS (atomic absorption spectrophotometer) after wet digestion. The values of trace metals [minimum~maximum (mean), mg/kg] in vegetables were as follows; Hg: 0.0001~0.019 (0.002), Pb: 0.001 ~0.28 (0.02), Cd: 0.001~0.078 (0.016), As: 0.001~0.06 (0.02), Cu: 0.06~24.81 (0.77), Mn: 0.17~15.12 (2.32), Zn: 0.13~28.70 (2.51). These results showed that metal contents in vegetables on domestic markets were similar to those reported in other countries. The weekly average intakes of lead, cadmium and mercury from vegetables take 2~7% of PTWI (Provisional Tolerable Weekly Intakes) that the FAO/WHO Joint Food Additive and Contaminants Committee has set to evaluate their safeties.
