This study investigated the development of eyeglasses and design transition in materials and types through literature survey. The scope of this study on the basis of the 15th century, for this study survey reaches from the 15th century to modern. The result of this study were as follows. Real magnifying glasses was first mentioned by the Arab physicist al-Hazen who was famous of his treatise on optics. The oldest documents which explicitly refer to the art of making lenses for eyeglasses and magnifying glasses were the Venetian artisans of 1300. In the 15th century someone thought to remedy the unstability of glasses by securing the bridge on the forehead. But it was only in the 17th century that someone contrived to stabilize the frame by strapping it on the face by means of fine cords that reached behind the ears. Eventually in the early years of the 18th century the English optician Edward Scarlett invented the rigid earpieces which solved once and for all the problem of holding the eyeglasses firmly in place. In the 19th century, eyeglasses' fashion were monocle and pince-nez. In the 20th century, various lenses and frames were appeared. Therefore eyeglasses to correct defective sight, sun-glasses, as well as a most succesful item among modern fashion accessories.

This study focused on front-blouse-type skirts from the 15th and 16th centuries and aimed to investigate their formative characteristics and wearing patterns. Previous studies, literature, records, paintings, and excavated clothing items were used as research materials. The researcher categorized front-blouse-type skirts into three types based on the construction method. The first has the front-center portion of the skirt folded up, the second has the center portion cut short, and the third has horizontal dart pleats on either side. An examination of 48 items from 18 excavation sites of front-blouse-type skirts showed that only the front-center portion folded up type appeared in the 15th century, and it was only in the 16th century that the other forms of skirts were worn. Finally, based on the analysis, the pattern of wearing front-blouse-type skirts and their changing factors was deduced. Front-blouse-type skirts were identified as ceremonial skirts that were popular in the 15th and 16th centuries among the types of long skirts available. The popularity and usage of this type of skirt began to spread gradually in the 15th century. In the 16th century, various types of front-blouse-type skirts were brought into vogue by the royal family and the external register. It can be inferred that the popularity of front-blouse-type skirts gradually declined in the 17th century as other types of long skirts, folding skirts, and Sran type skirts emerged.

The Purpose of this article is to study the excavated women's costume of the Joseon Dynasty, and to help identify the period of those costumes with the time of the burial unknown. The excavated women's costume is concentrated in 16th to 17th century, and the reason is due to the method of the burial. The characteristics of costumes from each period is as follows. The special features about 15th century costumes are the women's Dan-ryeong(round-collared jacket), Dae-gum style shirt(shirt with the squared collar facing each other), and skirt with horizontal dart. The 16th century costumes are the women's Dan-ryeong, wide Jegori with various length, skirt with horizontal dart, skirt with its hem folded, and pants with shoulder strap. In the 17th century, the formal dress changes to Won-sam from Dan-ryeong. The collar changes from the squared shape to the cut Dang-ko collar, and the skirt with its hem folded is not seen after the early 17th century. The long jacket changes to Dang-ui and gets settled, and the clothes becomes smaller and tighter. In the 18th century, the women's formal dress gets settled to Won-sam and Dang-ui, and the pants with shoulder strap is no longer seen. Jegori becomes shorter and smaller compared to those from the 17th century, and again gets wider and bigger in the late 18th century, and it leads to the change of making a big sized shroud.

This study applied the text frequency method to analyze the crops prevalent during the Chosunwangjoshilrok dynasty, and categorized the results by each king. Contemporary perception of grains was observed by examining the staple crop types. Staple species were examined using the word cloud and semantic network analysis. Totally, 101,842 types of crop consumption were recorded during the Chosunwangjoshilrok period. Of these, 51,337 (50.4%) were grains, 50,407 (49.5%) were beans, and 98 (0.1%) were seeds. Rice was the most frequently consumed grain (37.1%), followed by pii (11.9%), millet (11.3%), barley (4.5%), proso (0.8%), wheat (0.6%), buckwheat (0.1%), and adlay (0.05%). Grain chronological frequency in the Choseon dynasty was determined to be 15,520 cases in the 15^th century (30.2%), 11,201 cases in the 18^th century (21.8%), 9,421 cases in the 17^th century (18.4%), 9,113 cases in the 16^th century (17.8%), and 6,082 cases in the 19^th century (11.8%). Interest in grain amongst the 27 kings of Choseon was evaluated based on the frequency of records. The 15^th century King Sejong recorded the maximum interest with 13,363 cases (13.1%), followed by King Jungjo (8,501 cases in the 18^th century; 8.4%), King Sungjong (7,776 cases in the 15^th century; 7.6%).

The research started from the consideration that, although many aspects of the Milanese Early Renaissance are well known today, thanks to a vast literature, only few studies, so far, have paid attention to the ordinary world of architectural work - and its obscure protagonists - of this area and this period. Moving from the belief that this topic is crucial for a complete understanding of the 15th century architectural world, characterized by a progressive overlapping of roles and responsibilities in the worksites, this study aims to provide a contribution to expand the understanding of this matter, by focusing on a particular aspect of it: the role of the public administration in the architectural activity. In particular, the paper analyzes the characteristics of the "Office of the engineers of the Municipality of Milan", one of the major public architectural institution of the Duchy of Milan in the 15th century. Through an extensive archival survey, conducted in the major archives of Milan and Lombardy, the research achieves two main findings: a) the reconstruction of the complete Office staff throughout the 15th century and, b) an outline of the role and identity of the Office and its officers, through the elaboration of data collected. In particular, professional roles, technical duties, cultural background and tasks of the officers, together with Office management, appointment procedures and salary conditions are highlighted. This research, not meant as an ultimate study on the topic discussed, is intended to provide some material and reference points for further researches that will aim to expand the understanding of this matter.

Through big data analysis of the 'Joseonwangjosilok', this study examines the perception of ginseng among the ruling class and its utilization during the Joseon era. It aims to provide foundational data for the development of ginseng into a high-value cultural commodity. The focus of this research, the Joseonwangjosilok, comprises 1,968 volumes in 948 books, spanning a record of 518 years. Data was collected through web crawling on the website of the National Institute of Korean History, followed by frequency analysis of significant words. To assess the interest in ginseng across the reigns of 27 kings during the Joseon era, ginseng frequency records were adjusted based on years in power and the number of articles, creating an interest index for comparative rankings across reigns. Analysis revealed higher interest in ginseng during the reigns of King Jeongjo and King Yeongjo in the 18th century, King Sunjo in the 19th century, King Sejong in the 15th century, King Sukjong in the 17th century, and King Gojong in the 19th century. Examining the temporal emergence and changes in ginseng during the Joseon era, general ginseng types like insam and sansam had the highest frequency in the 15th century. It appears that Korea adeptly utilized ceremonial goods in diplomatic relations with China and Japan, meeting the demand for ginseng from their royal and aristocratic societies. Processed ginseng varieties such as hongsam and posam, along with traded and taxed ginseng, showed peak frequency in the 18th century. This coincided with increased cultivation, allowing a higher supply and fostering the development of ginseng processing technologies like hongsam.

This study was conducted to examine the chronology of Taesil Seokham(Taesil Stone Boxes) stored in Taesil of the Joseon Palace and classify the styles to discuss how these boxes have developed. By doing so, this study defined the archaeological styles of taesil seokhams in the chronological order. Although taesil seokhams are placed when taesil are first created, they do not have any texts engraved on them and it is difficult to gain information only from examining taesil seokham. However, Taejiseok(memorial stones buried in Taesil) and Agibi(gravestones buried in Taesil) were created along with taesil. These resources were examined and compared with literature records to find when each taesil seokhams was created. The critical elements to consider for the chronological arrangement were both the cover and container of the boxes and the transition of their style could be classified into four major stages. In detail, the Joseon Dynasty's taesil seokhams initially inherited the style of the Goryeo Dynasty to be formed into rectangular boxes. Through the transition of the mid and late 15th Century, the semi-circular cover with cylindrical container became the popular style in the late 15th Century. In the late 16th Century, the style of the previous period was further developed to add some decorative elements, such as projecting ornaments, but the ornaments were added for functional purposes rather than artistic purposes. However, the style went back to the semi-circular cover with cylindrical container in the early 17th Century. From the mid 17th Century, various styles appeared with ornaments only on the cover, cone-shaped cover with no ornament, or mortar-like container. However, a new style of cone-shaped cover with ornament emerged between the early and mid 18th Century and continued to stay until the mid 18th Century. In the mid 18th Century, the cover remained unchanged, but the container became a keyhole-shaped space with one side forming a "ㄷ" shape. However, in the late 18th Century, the most typical style of the semi-circular cover with cylindrical container reappeared to show that this is the most universal style. Last, in the mid 19th Century, the cover changed from semi-circular to rectangular with flat top. After this, the taesil seokhams began to disappear. In terms of style, it can be classified into four stages. In the early Joseon Dynasty, the taesil seokhams were underdeveloped and inherited the style of the Goryeo Dynasty (Stage I; 1401~mid-15C), but Joseon's unique style began to develop from the late 15th Century (Stage II; 1477~1641). After that, partial ornaments were added for adornment (Stage III; 1660~1754), but the typical style reappeared in the late 18th Century to finally degrade in the late Joseon Dynasty of the mid 19th Century (Stage IV; 1790~1874). This arrangement of style and chronology would greatly help archaeologists anticipate the time and owner of taesil seokhams even if only taesil seokhams are discovered without any records. * Tae(胎) : Placenta and umbilical cord * Taesil(胎室) : A facility(chamber) of burying Tae(胎) in rite when royal descendants are born.
