4.2. Pengujian Sistem
Setelah implementasi sistem selesai, maka tahap selanjutnya yang akan dilakukan adalah pengujian sistem. Hal ini dilakukan untuk mengetahui apakah sistem berjalan
sesuai dengan rancangan sebelumnya.
4.2.1. Pengujian Sistem Tahap Crawling
Pengujian yang dilakukan adalah proses crawling. Proses crawling dilakukan secara online. Data jurnal yang ada pada sebuah halaman website, akan diunduhdan akan
masuk secara otomatis ke dalam database tabel_konten. Tabel_konten memiliki 6field yaitu id_konten, url, konten_html, konten_teks dan kategori. Dapat dilihat pada
Gambar 4.8.

4.2.2. Hasil pengujian proses stemming
Pada Gambar 4.9 kata yang sudah di stemming, ditentukan jumlah bobot per kata. Contohnya, jika ada kata yang sama pada satu jurnal tersebut, maka bobot
stemnyaadalah jumlah dari kata yang sama.

4.2.3. Hasil pengujian bobot dan normalisasi
Hasil dari pengujian ini akan didapatkan bobot dari kata yang sudah mengalami proses stemming seperti pada Gambar 4.10.

4.2.4. Hasil pengujian nilai relevansi
Hasil dari pengujian ini, akan didapatkan nilai relevansi. Hal ini membuktikan bahwa jurnal yang dibandingkan akan berhubungan Gambar 4.11. Sehingga dalam
melakukan proses pencarian jurnal, dapat dilihat bahwa jurnal yang dicari memiliki relevansi dengan jurnal yang lainnya Gambar 4.12.

Gambar 4.11 Hasil Pengujian Nilai Relevansi
Pada Gambar 4.11 diketahui bahwa, id_topik satu jurnal nomor satu dibandingkan dengan seluruh jurnal yang ada pada database. Contohnya, jurnal
dengan id_topik 1dengan id_page 10. Hasil dari pengujiannya yaitu, kedua jurnal tersebut memiliki nilai relevansi sebesar 0.030952380952381.

Konten
The intratumoral distributions of [18F]FDG and [64Cu]Cu-ATSM have been reported to
be similar in adenocarcinomas but different in squamous cell carcinoma SCC in clinical
studies. In the present study, we compared the intratumoral distributions of these two tracers

a SPECT biomarker of tissue injury identifying cell death. The objective of
this study is to investigate the potential of DU imaging to quantify capillary

which retain
the histological
characteristics of the original tumors, and in cancer cell line xenografts of corresponding
origin, to
investigate the
underlying mechanism of the distinct FDG and Cu-ATSM
distribution patterns in adenocarcinoma and SCC. Methods CTOSs derived from colon
adenocarcinoma and lung SCC and cell lines established from colon adenocarcinoma and
lung SCC, which were used for comparison, were
subcutaneously transplanted
into immunodeficient mice. One hour after
administering [14C]FDG and [64Cu]Cu- ATSM,
the intratumoral
distributions were
compared in the xenografts by using dual-tracer
autoradiography. Adjacent
sections were evaluated for necrosis, vasculature anatomy, Ki-67 antigen, and
pimonidazole adducts using hematoxylin and
eosin and
immunohistochemical staining. Results There was a higher
regional overlap of high FDG and Cu- ATSM
accumulations in
the adenocarcinoma CTOS xenografts than in
the SCC CTOS xenografts, while the overlap in the adenocarcinoma cell line
xenograft was lower than that observed in the SCC cell line. High FDG accumulation
occurred primarily in proximity to necrotic or pimonidazole adduct positive regions,

Results Lung DU uptake increased significantly p amp;lt;0.001 by 39

respectively, compared
to normoxic rats. There was strong
correlation r2 =0.82, p =0.005
between lung DU uptake and the number of
cleaved caspase 3 CC3 positive cells, and endothelial cells accounted for
more than 50 of CC3 positive cells in the hyperoxic lungs. Histology
revealed preserved lung morphology through 48hours. By 60hours there
was evidence of edema, and modest neutrophilic infiltrate. Conclusions
Rat lung DU uptake in vivo increased after just 48hours of amp;gt;98 O2

adenocarcinoma CTOS xenograft had the stereotypical glandular structure, resulting
in more intricately mixed regions of live and necrotic cells compared to those

primary contributors to the enhanced DU lung uptake, and support the
utility of DU imaging for detecting
early endothelial cell death in vivo.
