The popular landscape paintings in Jaseon Dynasty had become the prototypes of the paradise of people and played the essential role in making the typical types of garden in those times. The representative types of the paintings include , , and etc. They made ways to produce the typical types of Joseon landscape gardens such as 'Dowon Type Gardens', 'Gugok Type Gardens', 'Prospect Type Gardens' and 'Gilji Type Gardens' etc. The types of garden above showed their landscape characteristics corresponding with the types of painting respectively. The 'Dowon Type Gardens' mostly located at the mountain valley showed enclosed landscape suited for refuge it corresponds with the composition of . The 'Gugok Type Gardens' mostly located at the long and winding valley composed of sequential sceneries with open and enclosed views corresponding with the composition of . The 'Prospect Type Gardens' located mostly m the hilly sites holds open views contrasting with the earlier types, and activated with the influence of . The 'Gilji Type Gardens' influenced by extended their territory beyond the main garden and made the vicinity areas, including the whole village, a paradise in respect with feng shui. Most of the garden types in Joseon Dynasty have alternated the bipolar characteristics of Prospect and Refuge in time and area respectively.

This paper is to compare the contexts and old place names in old county maps of Goryeong-hyeon(高靈縣) according to the four types of maps. 23 maps covering Goryeong-hyeon were collected from the old county-map atlas(郡縣地圖帖) and Eupji(邑誌). The first type(named 'picture county map') included 8 county-maps in which information of military, and administrative contents are mainly mapped. The second type(named '1-ri grid system map') included 4 county maps in which information about beacon routes and road systems were regarded as very important. The third type(named '20-ri grid-system map(方眼地圖)' included 4 county-maps which were drawn as same scale with 20-ri(里) grids. The fourth type(named 'local county-map(地方郡縣地圖)' included 5 county maps which were drawn by local mappers. Types of toponyms which were included in maps are different by the propose of map-drawing. In the picture county maps, place names from military, and administrative contents are written. In the 1-ri grid system county maps, place names especially from military and transportation are fluent. In the 20-ri grid system county maps, generic name from natural environment, such as mountains are very fluent. In the local county maps, city-walls and castles are drawn exaggeratively and detailed generic name from warehouses and villages are written in those maps. This study shows that Daedongyeo-jido was drawn on the basis of 20-ri grid system county maps with the supplementation of geographical information.

This exploratory study aims to review the risks and threats of social network services(SNSs), particularly focusing upon the policing perspective. This paper seeks to acknowledge the present risk/danger of SNSs and the very significance of establishing a strategic framework to effectively prevent and/or control criminal misuse of SNSs. This research thus advocates that proactive study on security issues and criminal aspects of SNSs and preventive countermeasures can play a significant role in policing the networked society in the time of digital/internet age. Social network sites have been increasingly attracting the attention of entrepreneurs, and academic researchers as well. In this exploratory article, the researcher tried to define concepts and features of SNSs and describe a variety of issues and threats posed by SNSs. After summarizing existing security risks, the researcher also investigated both the potential threats to privacy associated with SNSs, such as ID theft and fraud, and the very danger of SNSs in case of being utilized by terrorists and/or criminals, including cyber-criminals. In this study, the researcher primarily used literature reviews and empirical methods. The researcher thus conducted extensive case studies and literature reviews on SNSs. The literature reviews herein cover theoretical discussions on characteristics, usefulness, and/or potential danger/harm of SNSs. Through the literature review, the researcher also concentrated upon being able to identify a strategic framework for law enforcement to effectively prevent criminal misuse of SNSs The limitation of this study can be lack of statistical data and attempts to examine previously un-researched area in the field of SNS and its security risks and potential criminal misuse. Thus, to supplement this exploratory study, more objective theoretical models and/or statistical approaches would be needed to provide law enforcement with sustainable policing framework and contribute to suggesting policy implications.

A field experiment was conducted to evaluate the effect of slow-release fertilizer on the yield and quality of the third-harvest tea leaves. The yield of the third harvested tea leaves was decreased to 5.8-14.4% in slow-release fertilizer block, except to the N $50kg\;10a^{-1}$ ($316kg\;10a^{-1}$), compared to traditional urea treatment ($313kg\;10a^{-1}$). Nitrogen uptake and nitrogen uptake efficiency of slow-release fertilizer was reduced as nitrogen application level increased. The contents of chemical components related to the tea quality such as total-nitrogen, total amino acid, chlorophyll and theanine were somewhat lower in the slow-release fertilizer treatments, except to the treatment of N $50kg\;10a^{-1}$, than those in the traditional urea application, but those of tannin, caffeine and vitamin C were not different among the treatments. In scoring test, apparence and quality of green tea of the slow-release fertility treatments were not different, except to the N $40kg\;10a^{-1}$ treatment, compared to those in the treatment of urea. In conclusion, slow-release fertilizer and conventional urea treatments showed not different in both yield and quality of green tea.

This study was conducted to investigate the quality characteristics of makgeolli containing aronia, (Aronia melanocarpa (0-1.9%)). After an initial decrease in the range of pH from 4.93-5.04 to 3.43-3.61 over a period of 6 days, it gradually increased until 14 days. As the fermentation proceeded, sugar contents and reducing sugar contents initially increased in majority of the samples, and subsequently decreased after 2 days. Total acidity contents increased until 6 days and then became higher as the content of aronia increased. Total acidity levels were within the range of 0.50-0.62%. After 14 days of fermentation, the alcohol contents ranged between 11.97 and 14.13%. Over the same time span, the amino acid content increased from a range of 1.57-2.22 to 5.86-6.92%. The microbial cell count and yeast colony count increased over the initial 4 days and then gradually decreased. Total polyphenol content and total flavonoid of aronia makgeolli were significantly higher than those of the control group. Based on the sensory evaluation, makgeolli with 1.3% aronia demonstrated the highest overall acceptance.

This study determined the hazardous heavy metal content of mushrooms from markets in Seoul, Korea. One hundred and fifty mushroom samples were digested by the microwave method then the hazardous heavy metal (Pb, Cd, As, Cr, Ni and Hg) content was determined by the inductively coupled plasma-mass spectrometry (ICP-MS) and mercury analyzer. The average values of heavy metals in the samples were as follows: (mean [minimum-maximum], ${\mu}g/kg$); Pb 7.8 (1.9-30.0), Cd 45.3 (0.7-292.4), As 54.6 (24.2-229.3), Cr 42.6 (8.4-334.3), Ni 22.4 (up to 180.4), and Hg 8.9 (2.0-25.0). The contents of hazardous heavy metal in mushrooms were lower than those reported previously and also lower than the Provisional Tolerable Weekly Intake (PTWI) limit prescribed by the FAO/WHO. Thus, it could be suggested that the hazardous heavy metals levels in the mushrooms of retail market were adequately safe for consumption.

The political dynamics of Malaysia in 2016 should be seen as a process of losing an political opportunity mainly due to the split in opposition parties. The opportunity for political development was triggered by the ruling party in crisis. The ongoing 1Malaysia Development Berhad (1MDB) scandal involving the Prime Minister Najib Razak would have provided a favorable condition for the transfer of power. The opposition parties have however failed to utilize the chance that has arisen since the general elections in 2008 and 2013 due to the chronic problem of disunity. It can be seen as distortions of political development referring to a phenomenon in which a chance for regime change formed by the crisis in authoritarian regime is distorted by internal conflicts among opposition parties. Malaysia's political turmoil seemed to paralyze its economy while foreign policy was used as a tool for domestic politics. It was reported that the key economic indicator have worsen including exports and budget deficit. The ringgit had dropped to its lowest level since the economic crisis in 1997-98 which was mainly attributed to diminishing credibility on the Najib's administration. Najib's political struggle has also impeded Malaysia's foreign policy which has attempt to embrace China and the Rohingya issue. The chance to manage key risks would be diminished if oppositions' disunity continues as there is speculation that the general election could be held in 2017.

Mt. Hee-yang is located in Mungyeong-si, Gyeongsangbuk-do, South Korea. Through the analysis and interpretations of twenty-two different ancient writings which covers Mt. Hee-yang, and three times of field studies, I tried to analyze the cognition of our ancestors in those days regarding Mt. Hee-yang. Since Mt. Hee-yang goes very deep in the mountain range, Mt. Hee-yang was recognized as appropriate place for seclusion or operating Byeolseo. From the era of Silla, in terms of Fengshui, Mt. Hee-yang was also interpreted as an image of either a phoenix flying into the sky(鳳凰登天) or a valley of a phoenix and dragon(鳳巖龍谷). This cognition comes from its formations of topographical features, and continued to the era of Joseon Dynasty. The purposes of excursion were to retrace the course of predecessors, to attain one's long-cherished desire to visit, or to enjoy holidays. From the analysis of Mt. Hee-yang's visitors, the average social status of them is lowered a lot around the end of Joseon Dynasty, compared with the early period of Joseon Dynasty. Studying the visitor's route of Mt. Hee-yang, I could see the places that are highly-recognized were the top of Mt. Hee-yang, Seonyudong(仙遊洞), Bakundae(白雲臺), Yayuam(夜遊岩). Mt. Hee-yang was recognized as Sun-kyung(仙境) where Sin-seon(a taoist hermit with miraculous powers; the sage of old) lives, and mostly it was main destination of visit while Bakundae(白雲臺) was perceived diversely on each visitor because of its strange scenery.

The $14^{th}$ general election which should be held by August 2018 has been a dominant factor for Malaysian politics, economy, social changes and foreign policy in 2017. UMNO, the dominant party within the ruling governmental coalition, has focused on securing Malay support, voters which made them to sought political cooperation with PAS, Malaysia's Islamist opposition party. A consequent event followed by the strategic ties between the two parties is the rise of political Islam in Malaysia though PAS' 'Islamization' or 'desecularization' has never been adopted by UMNO. The rise of political Islam and Malay support have become the most important factor for the next election, which increasingly enhanced the role of 3R of Malaysia politics; Race, Religion, and Royalty. The Pakatan Harapan (PH), the newly formed opposition coalition without PAS, has elected Mahathir Mohamad, the former Prime Minister, as its candidate for prime minister. Malaysian economy and foreign policy seem to be subordinated to politics. Stabilizing ringgit and restoring economic growth enabled the Najib's government to reveal 'election budget' for 2018. Najib has spoken out Islam-related international issues including the Rohingya crisis and Jerusalem issue. It is to some extent the extension of domestic politics. The rise of political Islam will be a highly influential not only in the coming election but in the political and social development in the aftermath of the election.

In this paper, system dynamics considering dynamics and time was examined to study the changes in system structure according to reinforcement (policy intervention) of regulation and punishment for fishing boats, and the strategizing directions were analyzed. Until now, regulations and punishments on fishing boats have been conducted temporarily and short-term as a precautionary measure to prevent accidents and imposed penalties. However, due to various anomalous side effects, the expected results were not achieved, negligent accidents occurred constantly, and follow-up measures were repeated. Resultantly, the regulation and punishment of fishing boats is a reinforced safety standard, and there is a necessity to improve facilities, equipment, and industry, and develop technology (including time delay) to prevent accidents. However, as the negative (illegal) activities continue without immediate and significant resistance, the safety blind spot for accident prevention cannot be minimized. Thus, policy intervention based on linear thinking without sufficiently considering variables of the dynamic mechanism and time can distort the basic values pursued by the policy. For the regulation and punishment of fishing boats, a strategy to supplement the mechanism should be prepared prior to the preparation of reinforced safety standards. Improvement and development of related technologies, mandatory training hours for anglers, fishing industry, and related organizations, proposal of specific action plan for Fishing Management and Promotion Act for growing fishing-related industries.
